Well mine is close... UL1. This was suppose to be the Pocket Mechanic but never got my decals done and then sold it. Plett 290/30/4 torque version on 12 cells and 642. It hauled. I would say it ran 35ish. With lipos today it would have been wicked fast. I think I had Gp3300 cells for this one. I still have some pletts so I still have a chance to test those motors with lipo. Looks like I did not have the wings on either. I knew those would not take the tumbles so I never put them on.

It is really deep red...not sure why it looks like friggin bubblegum...oh wait...no digital camers were around then. Where does time go :)

Pink is cool if you are the fastest boat at the pond.. but if your not............................:bounce:..:just-kidding:.. i know its red.. its just the wrong boat in the wrong thread.. .i bet you knew that tho....:confused2:

I just wanted to show off my old boat. It was the fastest on my lake...even though I am the only one on my lake! That proto type looks like the wood hull.

But back to your point...yes, Pink is certainly my favorite color (aerosmith dude) You would probably like the name of our BBQ team "Pink in the Middle" nothing much but a few weekends a year to get out a little BBQ, college girls, keg, jello shots and this usually goes on for two days...oh wait and a 40' RV with Dish and 1000 watt sound system...I only have one rich friend and he seems to not be able to stay married. Good thing or the RV would be history.

I'm pretty sure you were burning that stinky fuel while we were cooking ESCs and burning 1200 mah nicad cells! I thought I went to heaven when the 2400s came out. They could deliver a good 15-20 amps and usually dump before the race was over. Talking about propping right!

grim dood these images look so friggin scale!

im planning to cut out that black windshield and find me some thin clear plastic and cut it to match the black windshield,glue it and add very tiny little painted bolts over a very thin strip of black paint to make the look of where the glass meets the hull. (you dig?) THAT my friend should really give a scale look on this hull. i dont care what any1 says, im glad this hull was designed!!!:thumbup1:

you see what im talkin bout? thats what im mean....

but guess what im actually gonna do? im actually gonna get the front cockpit piece and build a lightwieght cockpit out of light balsa wood or somthin i could use. suggestions are open. cut to the shape of the inside (lol man its kinda hard to explain) BASICALLY MAKE A RACING SEAT WITH THE REST OF THE WHOLE 9 YARDS!

then, im going to CAREFULLY cut the black windshield off leaving a VERY thin strip of it left so i can glue the new CLEAR windshield on along with the same little bolts you have on that t-hull....

think about it!! you never see somthin like that on a model hydro! im sure some1 has done it....AND ITS SOOOOO EASY!

if any of you guys out there are bored and wouldnt mind doin this to your model go for it!!! as soon as i get my model in my hands, im going to begin that project and take many pictures as i can to start a scale look on a BADASS model !!!

so if any1 has any suggestions on what material i can use to make a small
lightwieght cockpit for the ul-1 i'd love to hear it!!!

once again thanx grim!!!!!

Cool site. Thanks. Back when I was manufacturing UL-1 hulls and ESCs I sponsored Jerry at a couple races. I think that was Detroit in 2000 or so, and maybe Evansville. What a blast - full size UL boat with an "RC-Hydros.com" logo on the tail! I built a Pocket Mechanic for the owner (my UL model was scale of the UL-72 & UL-125/UL-10 hulls).

Almost every one of the full-size racers is a really cool guy.

Same as noted in other posts....MaxAmp 5250s with the Grimracer 40X57/3.

Runs were 47-48 mph 1st lap...about 1 mph slower than last time with nothing changed. I figure the choppy conditions slowed me some....less time with the prop in the water. She ran great and took everything (full speed) I gave her in the corners. Repairs still holding up too. :thumbup1:

I won the race by staying out of everybody's way and finishing! haha. Actually, I was pretty impressed with the Miss Elam. It runs good! This was the first run ever on my UL-1 and it held it's own pretty well even with the stock prop. The guys who have been running theirs a while and have experimented with props and strut depth, etc. were faster than me by a couple of mph but they all flipped or smoked and didn't finish. The next heat after this one I changed from the stock plastic prop and put on the grimracer 40x52/3 and she came alive even more. Next time I get a chance to run, I'll play around with some more setups. I love the way the boat drives. Rock solid. I will tell you one secret, I'm running 5000mAh batts. The guys running smaller (lighter) batts couldn't keep the boat on the water! Weight is your friend!

Cheers!

One other thing, two of the guys were melting the solder on the motor/esc bullet connectors! Their boats were fast as hell, one was running an Octura M640 and the other an M645. They were scratching their heads. Simple...they were overamping with those props, generating enough heat to melt the solder. One of them had his ESC fail as well although it didn't smoke.

I've read somewhere that the M645 prop is the secret. I have one too but I'm NOT going to use it if it is gonna fry everything. Could be their strut needs to be raised more. Basically I'm just a Sunday boater and don't have the time or inclination to fart around with stuff and spend any more than I have to. I do know the boat runs great with what I have. After all, the secret to winning is finishing the race.... right?

Capt. Crash
02-23-2009, 02:19 PM
Great report....and I agree with the prop selection too. Although I'm only using the 40X57/3 and getting about 3-4 mph more out of it than the 40X52/3, it is a trade off in run time. I was getting 3 good 2.5min runs out of the less aggressive prop vs 2 runs out of the 40X57. Both set ups are very stable after shifting the weight forward though. I'm glad the Elam is running good too....it will make for more selection in a good ole back yard dog fight. :thumbup:

sailr
02-23-2009, 02:54 PM
The only problem I'm having using the 5000mAh packs is the boat wants to submarine really bad from a dead stop startup. Not sure if strut angle would help me here or not. I hate to screw with it too much because it's running really well. Not sure how long we ran but probably close to 10 minutes. I only put 3000mAh's back into my 5000 flightpowers after that run. Nothing was even warm.

Capt. Crash
02-23-2009, 03:05 PM
I'm using 5250s and have to goose it full power momentarily to get out of the hole...if you have a air dam it will be worse because it drags in the water till you get up. I have no problem getting up on plane with mine and it hooks up (quits cavitation) within a few feet of giving full power once it's up. Sometimes it takes it 20-50 ft to hookup if I just go full power from a dead stop.

sailr
02-23-2009, 03:51 PM
yep, I'll have to play around with it. Every time I goosed it, it went deeper...;-0 I figured the airdam would just be problems so I didn't put one on. The guys running them can't seem to keep 'em stuck to the boat anyway. My boat doesn't have any tendency to blow over so no worries.

My 5000's will just BARELY fit in there lengthwise. What kind of 5250's are you using?

EATMYWAKE
02-23-2009, 07:48 PM
and what run times you getting with the 5250 batterys and what prop??? i cant seem to find an answer. and can't you guys just give the boat a little throttle and a shove to get it on plane? almost like a running start. like the nitro hydro's. great pics sailr

sailr
02-24-2009, 03:47 AM
Of course we can throw the boat in on plane, no problem. It's if we stop out in the water for some reason or want to do a dead stop start, getting it on plane is a problem.

I didn't really time my runs with my 5000mAh batts. We throw the boats in, make a couple of laps on a 330' course, and then do a flying start and race for 6 laps. Our total time out there is probably around 3-4 minutes. With the 40x52/3 brass prop, I use about 3000mAh. So I'm really only getting one run on a charge.

Read post #46:

I simply scuffed the factory White paint before spraying on the Fluorescent Red lacquer. This is a beautiful high gloss glowing color lacquer that can be color sanded then buffed for even more shine.

Warning: DO NOT USE the Polycarbonate version of this paint. Polycarbonate paint is only used to spray inside clear lexan car/truck bodies.

The White primer you see in background is for another project. I never used it on this boat.

Andy/Detox, you can use the TS series of Tamiya paints, BUT test for compatability with Tamiya surface primer on a small portion of the pre painted surface after wet sanding. Tamiya paints are fantastic. All my boats are painted with this paint

Be extremely careful using Steel Wool on your electric boat. Two reasons. First, the magnets in the motor can 'suck up' small fragments of the steel wool and cause you some serious problems like shorting out the fields, causing premature bearing wear, overheating, etc. Second, anyone that has ever used steel wool on a full size boat only does it ONCE. The tiny fragments from the steel wool lay on the gelcoat of the boat and cause rust stains that will NOT come out!

If you can find BRONZE wool, that's the stuff to use. I have tried unsuccessfully in the Tampa area to find 'fine' or 'extra fine' 3m scuff pads. I haven't tried an auto paint store yet. That's next. In lieu of all of the above, I use 600-1000 grit wetordry sandpaper.

And your point is? You have to work with what you can get and won't cause problems like steel wool.

It would be well worth the effort to find some fine bronze wool or fine Scotch Brite pads. Fine sandpaper clogs TOO quickly and is difficult to hold on to while wet sanding.

Hi guys, I prepped the hull using 600grit wet. and then just started masking my lines using fine line tape. Canopy I used a gray scotch brite and special Sikkens product call Primer PO specifically designed for raw plastic, this ensures a good bond between the subrate and your paint (paint wont peel off when tape is taken-off canopy), I think every paint manufacture has this type of primer.

For the windsheild I just masked it off with fine line tape, I dont think its a decal detox.

No wrinkles, I didnt experience any wrinkles, but they can be avioded by not pounding on your paint, go nice and light on your first two-three coats. Also Laquer and Enamel dont MIX, be sure the products you use are compatable.

This is mine... I did open up the bottom of the hull and did some work in the turn fin area to get some strength and structure in there. I also did alot of work on the sponson ride pads. I shimmed and sheeted the right sponson so that it had 1 degree of dihedrial. I shimmed and sheeted the left sponson so that is was completely flat. I finished shooting color on Monday. I will start putting it back together later this week.

What is the theory of giving the right sponson 1 degree of dihedral?

If you look at most of the fast riggers, you'll find that the outside sponson is flat, and the inside is about 1-degree.... I believe they do this to promote better tracking and to counter prop torque. I think it causes one of the sponsons to have a tad more drag, which offsets the prop torque and helps the boat track straighter.


I like the upgrades... similiar to the ride-pads I added on mine, which put the sponsons at just about the same angles... I think mine is more like 0.5 degrees on the left and 1.5 on th right...

Based on the reports of sponsons walking with these boats, I might be inclined to increase the angles a tad more to see if that could be overcome, but I'd replace or properely tune the turn fin first. Many of the pictures I've seen show the boat riding on the bottom of the turn fin. If the boat is fighting that hook in the bottom of the fin, that'll cause issues... Maybe throw a straight fin on there to get everything else dialed, then start playing with the hook. I've personally never had good luck with hooked fins... and always just use a straight one with about 5-10 degrees of inward angle...

Darin alreay answered in detail. I was told that the flat and the 1 deg was the intention of the design. However, my hull had anhedrial angle on both sponsons. So, I went thru the process of making it right. As for the angles themselves, everyone has there ideas. Actually on Brian Blazer's 20 Whiplash it's the opposite. Flat right side and 1 degree dihedrial on the left. To each their own.

Sounds like the strait turn fin was a mistake. Go back to the curved UL-1 or bend the stait fin until it holds water in turns. My fin is tilted up a little. You can see the position of my turnfin against setup board in this link:http://forums.offshoreelectrics.com/showthread.php?t=7539

Here's a quote from UL-1 manual:

TURN FIN – The turn fin is what holds the boat in the corners
at speed. The turn fin can also be tilted back and forth to
change the way the boat handles. Tilting the fin up (positive)
causes the boat to run tighter on the water and tilting it down
(negative) causes it to run looser.

The corners were not a problem....it was the front stretch. The straight fin was fine everywhere except the straightaway. I had no lifting problem with the stock fin...I never had a blow over with it even with the prop all the up to 7/8" and running the 40X57. It is hard to get hooked up with that setup but it runs pretty light and fast. I will be going back to it after I complete surgical repairs of the damaged glass in the fin area. Time to do Darin's turn fin mod.:unsure:

You should also sand the paint and primer off the sponson and add a layer or two of glass on the outside. It's a larger project, but worth it in the end.

Buy all three then test to see wich one you like best. In perfect water my UL-1 reached 50mph using the m440 and the L40 x 57/3. I have not tested the L38 x 55 prop enough but it seems fast also. Flightpower 2s 25c 4900mah and Hyperion G3 2s 25c 5000mah lipo packs were used during all testing.

Water conditions play a big role in top speed. UL-l is very stable and fast in smooth slightly choppy water, but larger chop and race water will slow it down noticeably and make it more LOOSE. Playing with a more forward COG may correct this problem. I have two heavier 4s 35c 3300mah that I will mount sideways in front of hull. This may correct the looseness in choppy race water. Or adding lead may help also.

Here's My old UL-1, it was bought and backordered as soon as they came out, I love these boats, but this hull got on my last nerve and I sold it because of the turnfin mount.

My UL-1 was running high 40's ...maybe 47mph on a good day on an Ammo2300, and 45mm 3 blade prop, but as all good things come to an end... it took flight and blew over... as It floated to shore I noticed the whole turnfin was gone, bracket and everything, there was a nice neat hole in the sponson. So I parted it out and sold the hull on eBay. Good luck! lol

I hope to get higher top end than the already awesome stock 40x52/3 prop but with lower amp draw/temps. I'm looking for 46-47mph. I wanted to raise my prop up to about 3/4" but the bracket won't let me go any more than just over 7/8"...the factory height. So I will try it there first. The added weight in the nose and starboard sponson due to the added glass, should help keep the nose planted in the straights and sponson planted in the turns. :popcorn2: My boat is now pretty solid and should last a long time if I stay outta the wall.

I've not had one issue with my UL-1, and it runs awesome!
For an RTR under 300 bucks at tower that can run upper 40's (49.0mph on mine) with a decent prop out of the box, who can really complain.. :doh:
Not me

I just installed a Fiago 9xl and Hydra 120 in my UL-1. I will try it out later this evening if the winds calm down. I added two extra caps for extra insurance against esc failure.

That should rip pretty good:rockon2: Good luck

Changed my mind. I will be using the NUE 1515 1y/s (2200kv) with the Grimracer L38/55 prop. I will have to be very careful not to burn the ESC...no off and on throttle. If it does burn I will use my Hydra 240.

I couldn't get the L38x55 to handle well with my 2200kv motor. Good luck. I'll bet you like the L40x57 a lot better.

OK...back from the pond. Wind was blowing and water was a little rough so I couldn't let her rip, but boat obviously faster. The most throttle I could give was about 3/4. I will try again in the morning on smoother water

Hydra 120 esc temp...170 degrees:huh:
NUE 1515 1Y .............131 degrees
Two G3 4s lipo's..........98 degrees

OK...back from the pond. No GPS, but I would say 60mph easily using the L38 x 55 prop and NUE 1515 1Y (2200kv). Weeds are starting to be a problem...rudder would hang weeds and boat would slow down noticably (around 45mph). Boat was very stable on glass smooth water, but once UL-1 hit a small wake it would get very loose (it flipped once). I will add lead tape to the outer sponsons to maybe help stabilize boat better. FUN FUN FUN

ESC temp.....145degrees
Motor............135
G3 Lipos........101

Yea 60mph Ul-1, sweet, Is it stable at that speed or wanna blow over?

Very stable on smooth water with no sign of blowing over. More weight should help stabilize UL-1 in race water.

I think if I modified the sponsons of UL-1 by using less AOA it WILL handle rough race water better. This will take major surgery

Detox, what is AOA and how would you modify it? :confused2:

detox
05-30-2009, 11:10 PM
Angle Of Attack is the angle at which your sponsons attack the water WHILE RUNNING ON WATER. The UL-1 has what some say is excessive or too much angle (boat is flighty or loose even with the lower powered UL-1 motor/esc power). Rest your boat on setup board with bottom of strut resting on surface also. Look at how much the sponsons angle upwards toward front of boat. You want a little upwards angle, but less is best for a tighter running race boat (boat will be more stable and less flighty in race water). It would be difficult to change chage AOA of UL-1 without removing sponson bottom, but it can be done with LOTS of thought. There is a sweat spot.

detox
05-30-2009, 11:17 PM
On setup board with the boat resting on strut (strut adjusted 1" below hull) and sponsons, take a piece of 1/16 ply and slide it back under the sponson until it touches the ride surface. Measure the distance from where the ply touches to the Tale End of the sponson. You will notice the UL-1 has about 7/8" (I think). Shoot for about a 1.3" measurement if sponsons are modified.

Raising the strut (mine is set 1 3/16") will have some effect on AOA and make boat run tighter. Along with adding more weight in the correct places...usually up front.

Remember a wet or tighter running boat is a hotter running boat. Sometimes this will be harder on the ESC and Motor.

COG or Strut Angle maybe. I know nothing about Cats and very very little about Hydros.

I have a sprint cat which is very similar to the Mean machine. COG should be about 9.5" up from the transom. You should be able to adjust your COG with your lipos by moving them forward or back in the sponsons. Your mm should run on the last 3"-6" of the sponsons.

I was having difficulty getting the laser printer decals to come out with the proper yellow color so I just hand cut (3 hours later) all of that out of Yellow Monocote trim sheet. :smile:
