Blackjack 26

[forescott]

Just picked up a new blackjack hull & hatch off flea-bay. I've always wanted one, and was gonna purchase one as my first F.E. boat, but opted for the supervee instead.(I was turned off by the steerable outdrive) So I had a strut from a proboat thundercat and speedmaster rudder. I cant decide whether to use the H/K typhoon 500 outrunner(1800kv) or the castle 1512(1800kv). I purchased both, plus I picked up a proboat 45amp esc. and have a couple of turnigy 120's I can use as well. Also ordered a pair of flightmax 5000mah 40c 2s lipos. This will be a 4s for fun/5s for more fun setup!

[forescott]

I'm also using a 3/16 flex cable inside the stock stuffing tube w/o teflon.

[syncronized77]

What 3 blade prop are you running? In regards to the motor choices...I'm sure the Turnigy 500 is lighter than the 1512 so it may be more beneficial when running 4S. But if you're going to run 5S, I'm sure the 1512 will run much cooler than the TT 500.

[forescott]

I will probably end up using something like the x642. The one in the pic is a grim 40/57/3

[koontek]

Hey Scott,
I ran the castle 1512 1800KV (the one they have on sale) on my blackjack and got it up too 54.3 MPH on a chip carbon fiber 51 mm prop. I Just got my x648 prop that i need to put on and see what happens. here is the video

http://www.youtube.com/watch?v=xHXFf-tbDog

The motor ran really cool. At the time the cooling jackets where out of stock but i just got one so i think that should also bring the temps down even more.

[forescott]

Finished up the blackjack with a ul-1 motor(still awaiting the typhoon outrunner and castle 1512) and ran it today with 2-3300mah 4s packs in paralel (still waiting for my turnigy 5000mah 2s 40c packs to arrive). First run with the grimracer 40/57/3. The boat would not even plane!( I think because the thundercat strut is really thick around the prop shaft and wouldn't allow enough water around the blades) Then I threw on an m445 and that sure enough did the trick. I was a little weary of using a 45mm prop with the ul-1 motor, but ran it for 3-minutes and motor temp was 78 degrees! No gps yet, and it was a little choppy so I didn't get to really wind it out but its a little rocket!! My guess is mid forties with this setup. More results to come.

[blackcat26]

The 40x57 is more for lighter riggers and such. Been there....and tried that!

[forescott]

It was one of the smaller props that I had. I was suprised the blackjack wouldn't plane with it though.

[blackcat26]

Yeah the problem is the pitch for how small the diameter. Plus that boat may be a little heavy with 2 4s pack in it.

[6S HYDRO]

i gotta BJ hull and hardware (fullers) for sale in the swapshop. 80.00

[blackcat26]

Hey Scott, you may want to try and get a tapered washer or something for the front of that stru also. Looks like that flat edge might be causing some drag.

[forescott]

The strut is a little beefy for the blackjack!

[forescott]

Ran the blackjack again today and got a gps reading of 44mph. Boat was dipping to the right at slow speeds in a straight line. The only thing I changed was cutting 3/4 inch off the rudder and slight strut adjustment. Anyone know what might cause this? I'm stumped!

Cutting 3/4" off the rudder. Sounds like you have a case of torque roll now. A longer rudder will help combat that.

[forescott]

Made some changes to the blackjack. I flipped the rudder bracket around to move it out of the prop wash. Got a smaller strut to accomodate smaller diameter props. (now the hull looks like swiss cheese!) And am gonna try out the 1800kv typhoon outrunner with a proboat esc. Should have my 2s packs in a couple of days and gonna give it a try then!

[forescott]

2s packs came in. One had a bad cell. I had to send it back. Ran it with two 4s 3300mah packs in paralell. Ran really good on a grim 42/55 until the outrunner end cap came partially off and spun around like a knife! Locktited the screws this time and ran it again with a new S&B x-642. Great prop. Ran about 40mph on 4s. brought it back in and the motor was separating! Another set screw that came loose! Got it put back together with some more locktite. I ordered another motor I wanna try out. Got it from the castle sale. Its a little bigger in diameter and if its anything like the castle inrunners I'll be really happy with it!!

[LarrysDrifter]

Damn.Thats a shame on the outrunner.Hopefully the CC outrunner doesnt come apart.

[forescott]

It still works. Its a great 25 dollar motor. I'm starting to really like the outrunners!

[LarrysDrifter]

I bet.I heard one of my Aligns run in my buddies Apparation and was hooked on the sound alone!

[forescott]

I agree, but the turnigy typhoon doesn't have that "whine" :crying:

[forescott]

I got the castle outrunner installed today. Its larger in diameter than the typhoon, and it has that supercharged sounding "whine"!!

[LarrysDrifter]

Sweet!!:thumbup:

[forescott]

Unfortunately I think I puffed my 4s packs! They sat in the blackjack for a couple of days after I ran it. They were still plugged into the esc and I think I may have hit the lvc on my last run just before bringing it in. My hyperion charger wont charge them and says "check pack, low voltage" :doh:

[blackcat26]

No problem Scott. Charge them for a few minutes as a nimh and bring them back to a recognizable voltage. Then you will be cooking with crisco.

[forescott]

I was able to save 1 pack. Thanks blackcat!

[forescott]

I was able to get a run in today with the castle outrunner. Impressive motor! Got a gps reading of 37.8mph on the H/K typhoon outrunner(1800kv) on 2-3300mah 4s packs in parallel with an x642.

The Castle outrunner(same kv) got me 43.3mph with the same prop and heavier 4950mah 4s packs in parallel. Motor temp was around 110 degrees. I'm anxious to get some 2s packs to cut down the weight and gain a little mph. The blackjack is a little small for 4s2p.

Still not too happy with the performance of the 45 amp esc. Its too touchy and I have a seaking 60 that I'll probably replace it with.

[blackcat26]

I was able to save 1 pack. Thanks blackcat!

Oh well, one is better than none....

[Diesel6401]

Hey great minds think a like. I just got a BJ about 3 weeks ago from craigslist, guy is a member here and did a AMAZING job on it. Custom decals and fullers outdrive really setup it up wonderfully. I'm using this hull to break into the outrunners. I set it up with a Tiger outrunner I bought from the swap shop and a x642 did not gps it but after about 4 passes on 4s the motor came in at 105F and the esc was 65F (stock BJ 45amp), water was about 45F. This outrunner had watercooling, not sure why she came in so hot. It's only 1600kv and rated at 5s. I bought the typhoon outrunner last month and it took 4 weeks to get here from Hobbycity because I didn't use express shipping. Haven't had a chance to run that motor yet though. I also have the CC outrunner being sent, when you showed me it on the hotr thread I started I gained interest. Glad you like it, I will use a seaking 120 on mine.

Don't want to thread-jack but here she is. I call her Miss America lol

[tiqueman]

D, take the turn fins off. :buttrock:

[Diesel6401]

D, take the turn fins off. :buttrock:

I ran it only once and handled great. I'll have to get a better shot of the outdrive, it's freaking long as hell. OK, I will take them off, looking for mostly straightline speed anyway. Goal for this boat is learning outrunners!

[forescott]

You're gonna like the castle outrunner! I like not having to use a cooling can for the motor, but keeping the battery wires away from the motor is kind of a pain. I'm going through a lot of zip-ties!

Sweet, I ran mine along and zip-tied to the rail. 1 tie worked for me for the motor/esc wires.

[dano1]

Salutes the blackjack, nice ride

This is round 2 for me, had 1 sold it and wanted another 1. Got lucky on craigslist.

[forescott]

I got a brand new hull and hatch for 60-bucks. Couldn't pass it up!

[calcagno45]

Whats the bolt circle for mounting the Castle 34-24-1800 outrunner? 25mm?

[forescott]

2-holes @ 25mm, 2-holes @ 30mm

[JackBlack26]

Working on converting my Nitro to electric right now. I already layed a layer of glass along the whole bottom and I'm working on getting the hull prepped for paint. I was going to use a spare Feigao 1830kv, XL motor in it. I'm intrigued by these out runner motors now. Do they not need a cooling jacket? Castle still has the 32-24-1800kv motors at clearance prices. If they don't need a cooling jacket I will pick one up for sure!

Get one! No cooling jacket required. They are great motors. I am thinking about getting another for a spare.

[JackBlack26]

Thanks. I think I will order one.

So you're running the Castle out runner motor with a Pro Boat 45A ESC? It's holding up well?

[forescott]

Thanks. I think I will order one.

So far so good!

[calcagno45]

Thanks, going to order 2.

[JackBlack26]

Just placed the order for 1 to go in my BJ26 nitro conversion.:rockon2: I cant believe it was only $49!! I'm going to run it in with my water cooled Mamba Max ESC on 4S.

Should be here by the end of the week:thumbup1:

[forescott]

You can actually run it safely on 5s if you like. I'm getting 43-44 mph on 4s with an octura x-642.

[JackBlack26]

I'm going to try the Grim 42x55 with that motor. I really like that prop in my MG. Should make the BJ26 fly!

[forescott]

I tried that one too withthe typhoon outrunner. Great prop, similar performance to the 642.
Hmmmmmm...Miss G. My next toy!

[Diesel6401]

Hey forescott, hope you don't mind if I add to your thread a little. Just wanted to show what I got going on so far. Seems like we are both on the same page with the BJ and Outrunners. I need to get a eagle-tree asap, but once I get one I'll have some data. Here's the 3 motors I have for the BJ.

- Venom (KOS P1) 2000kv outrunner with bracket. I was really shocked the bracket was a direct mount to the BJ.
- CC 1800kv outrunner (same as forescott)
- Turnigy 500 1800kv outrunner (same as forescott)

[roadrashracing]

I'd hate to ask a dumb question but what is the difference between an inrunner vs outrunner?

[forescott]

Be my guest Diesel! Wow the p-1 motor mount lines up with the BJ mount holes. I also have one of these on the way! :spy:

[forescott]

With an outrunner, the outer part of the can spins instead of the inside. Outrunners typically have more torque and use less amps than inrunners. Obviously if the outer part of the can is spinning, then they cannot use a water jacket. Most outrunners have some type of fan/blade setup built in to the end of the motor can to circulate air when the motor spins. Thus they are air cooled, but can be used with a water cooled motor mount to aid in the cooling as well.

[JackBlack26]

Can anyone recommend what timing to set on the ESC for the CC outruner, or any outruner for that mater?

Thanks!!

[forescott]

Which esc? I use the 18 and 22 degree timing advance on the turnigy/seaking models. Most outrunners need high timing.

[JackBlack26]

Sorry, it's the turning 180A. I ran it today at the default setting which I think is like 15* and it ran like a bat out of hell!!

[forescott]

What prop did you use?

[JackBlack26]

42x55. I'll add the video just in case you haven't seen it. I don't have a GPS but it looks way faster than stock. Still have not adjusted the strut from how it came out the box so the bounce is still there even with the batteries hanging 1/2 out the back of the tray.

I'm guessing this setup should put the B26J in to the 50's considering it's lighter, no?

[forescott]

I have a pair of 3000mah 5s packs on the way to run in paralell. Should see 50mph then.

[forescott]

Went back to the typhoon 1800kv outrunner in the blackjack. The castle outrunner was a little too much for the 26-inch hull and was causing some big torque-roll issues. The smaller typhoon outrunner seems to be a perfect match with the turnigy 60A esc and 642 prop. Speed is around 40mph on 4s and the motor comes in at around 110 degrees after about 7-minutes run time.

WOW great info man. 7m run time that's impressive. I am still waiting for the weather to break here so I can run my setup with the 2000kv venom/suppo outrunner. I bought a eagle tree so I can get some good data. Gonna try it with the stock esc. Hopefully it handles the motor ok.

Oh man.. and Im currently working on stuffing 2 of those in one. :ohmy:

[JackBlack26]

What drive hardware are you going to use in the BJ Scott? I'm working on my second hull and have thought about making it a twin as well.

I never called you about the Genesis because I bought a 4074 2200 for it. I'll make it a twin when the 2200 gets boring, lol!

No worries. Ive got a couple SV stingers laying around so those are going on it. Its actually my neighbors boat. Trying to keep it as budget as possible. I layed it up in Carbon the other night and Im laying up the carbon sheet tomorrow to make the mounts, bulkhead, etc out of. I told him to start a build thread on it but hes a slacker. I may have to do it as a "look what Im building for my neighbor" thread

Just got my p-1 up and running today with the new hatch I've been waiting for. The 2000kv outrunner runs real nice in the p-1. Should be quick in the BJ!
