22Kv might be too much, hard to say. I've been fiddling with boats off / on for the past 3 somethin years. If there's one thing I've learned it's: there's a crap load of factors that affect how fast a boat goes & how well it handle's.

They can be very temperamental & frustrating - but when you get it right & the boats performing good, it's very satisfying - makes for a fun afternoon @ the lake.

Timing... start your setup at zero degree's timing & run it for awhile see how she does. If she runs good, then bump it to 3.75-deg & see what happens, more timing = more power = more speed - to a point, as I discovered.

Program boxes make dockside changes much easier. HK sells this one... http://www.hobbyking.com/hobbyking/s...ming_Card.html - stay on it for a few minutes & a "One time only offer!" box pops up with $5.69 price - click the files tab->face plate 2 - it's for boats. The HobbyWing boxes also work fine with the Turnigy's.

I ordered the 120 from china so waiting the 22kv I already have is going to be to much an 3 s right

looks good thanks for the photos of everything helps a lot , since i am waiting for the esc, and putting some money in it i might as well doll it up a bit. going to tear it down in the next few days. remove all the stickers and repaint it. i found a couple of nicks. i need to buff down and find some kind of body fill to use on this abs. have not had time to open up the receiver as yet. my last kid is a senior this year and plays ball. and been at bb games, but had a proud dad moment tonight she got home coming queen. anyway back to the boat. still debating on motor size , got to order one of the program cards.

[RCBoaterGuy]

Glad to help - good hear your kid made you a proud dad, no amount of $$ in the world can buy that

Regarding motors, suggestion... hold off for now. My boat is almost ready to go, need to finish adding expanding foam up front & a little in the canopy in case it blows off. All other upgrades are complete.

Once that's done, then can reassemble & take her for a test run. The 1800 PB motor is a lot more potent than the one I used for the maiden (6-pole marine vs 2-pole car). It may prove to be too much, it may not, only time will tell. Please remember, we're talking a thin plastic hull, it can only handle so much power.

Once I see how the boat performs with the 1800, then I'll be in a far better position to offer sound advice based on real world experience. IF, the 1800 works good... fine, you can look for one in the swap shop. If not, then we can go to plan B.

Meantime let me ask you about your battery inventory... how many 2s, 3s, 7-cell (8.4v) humps & so on. Hang with me, I have a good reason for asking

right now i have 4
Turnigy nano-tech 5000mah 2S 35~70C Lipo Pack
2 3s 40c 5000 mah flight max

ok, will do on the motor,

[okieman98]

well don't know what to do now, i sat down today today to tear her down and found some damage . guess one of the kids did something only had the boat in the water 3 times.101_2282.jpg101_2283.jpg

dont know if i need to find a new hull are just patch it and run it and don't fret on paint and stuff

[kfxguy]

O dang! What now? Time for a new one? Beware that the flex is going to lock up in it without mods....

[RCBoaterGuy]

Your in luck!!

I have a spare hull, brand new never been in the water

Bought the SW26v3 brushed version July 2013 (brand new) with the intent of converting it to brushless using the Proboat 1500Kv motor & 45amp ESC from MG29v1, but never finished - one of these days I'll list the motor, ESC + program card in the swap shop.

After doing the pre-maiden run clean up, during re-assembly I noticed the motor & mount assembly moved up'n'down a bit more than I was comfortable with (*because the plastic in that area kinda thin*), thought to myself, the 1500Kv motors are torquey so that might cause probs. Started out to reinforce the hull with fiberglass, but never finished. **That was one of the factors that played into my decision to go with a 2-pole motor, to reduce stress in that area.

After seeing how well the boat pictured in post #25 ran, I put the brushed one back in the original box with manual(s), decal sheets, stand, etc & put it in the closet where it sits to this day.

So far I've sanded the sides of the hull (interior only) with course sandpaper so the fiberglass resin will stick (finishing epoxy can also be used). And laid fiberglass tape in the motor area, it's tacked down with CA glue. This is the stuff I used... http://www.cstsales.com/glass_tape.html

Like I told kfxguy in post #14, want to focus my efforts on my IM31 & have the SW26 for a fun boat.

Regards,

up date, ordered replacement hull, and still waiting for the esc to come in,

What cooling jacket is used on the Tacon 2858-380XL-14T Brushless Motor??

[okieman98]

ok got hull and esc in. got to really decide what size motor i have to get. thanks rcboaterguy for the replacement.will start a tear down this weekend , hopeful this flu is on its way out now

[RCBoaterGuy]

I used this one... http://www.hobbyking.com/hobbyking/s...ize_Motor.html - for the maiden run. Once I got it positioned right, it kept the motor nice & cool on full throttle runs, which is how I ran it mostly. Power was supplied by a Sky LiPo 4000mAh 3S 40C battery. Ran stock plastic prop on maiden; had Chris (www.dasboata.com) apply his magic to the optional SS prop for the next testing session.

I am very happy with how well the boat ran**, but wanted to make some improvements. During re-assembly I could not get that cooler positioned correctly so it kept leaking during pressure testing - it's because of the longer can.

Don't if you noticed but that's a 60mm long can. Hard to get the cooler positioned so the O-rings will seal up on the front part of the motor & the last fin. So got one of these coolers... http://www.hobbyking.com/hobbyking/s...75mm_Boat.html - lot bulkier, but no leaks.

Originally got that Tacon motor for another project, but it proved to be a bit too much power** Didn't want to hassle with a new motor mount in that boat, needed the extra can length so I could put a aluminum cooling coil on the back side.

**Reason the motor proved to be too much for the original boat & made the SW26v3 haul butt is because it's really a 2044Kv motor (+ the extra torque from the 60mm can) - measured with one of these... http://www.hobbyking.com/hobbyking/s...Search=rpm%20m on 3S Battery. Just got that meter today, and just tested the motor before NHRA qualifying started on the deuce.

The blue aluminum cooler works fine on the shorter Tacon (and HobbyWing) motors like this one... http://www.hobbypartz.com/96m272-2848-2100kv-18t.html and these... http://www.hobbypartz.com/3330kv-rc-...car-motor.html

One of the improvements I made was to replace the stock SW26 motor mount with a IM31 mount (PRB4260), the holes for the hull mounting screws are 4mm rather than 3mm, gives some extra wiggle room to get better motor shaft / flex shaft alignment for smoother driveline operation. Also polish your prop shaft & bushing - see post #11.

I also covered hull reinforcement in that post, I'm in the process of doing that upgrade now, almost finished. Really stiffens the front of the boat, just feels a lot more solid. Have a feeling that's going to help tame the nose bouncing you see in a lot of the vids of these boats. Won't have to run the trim tabs so tight, allowing the boat to run looser for better speeds on smooth water.

Ok, this post is long enough, any more questions - feel free to ask.

[Tamelesstgr]

My gosh, thank you for all the great information and links!

[RCBoaterGuy]

Your welcome!!

The blue motor above on 2S = 22,200 rpm's same as the Tacon on 3S - for sale if your interested. Have too many motor's & radio's, couple spare ESC's too, trying to clear out the excess.

Have a pair of 2.4GHz surface radios with Rx's available also.

Will be posting updates of recent upgrades soon. Need to finish adding expanding foam to the front end, then can re-assemble.

My gosh, thank you for all the great information and links!

ok i ordering this servo need a mount from hk if they have them could not figure out what to order, also need a servo arm for the linkage that will fit this servo
