Jolly Cat Refit

[SJFE]

Yeah I know I havent finished the Rio yet. With the esc blowing in the hull I opted for some changes. It's not going to be a quick process. I'm still mulling a few things over. Anyhoo it's all cleand up. Just have a few more stickers to remove. Oh yeah & I ordered the replacment esc tonight. It will be here friday.

So what u going to do with it

SJFE what are the dimensions on that hull? looks pretty big

What are the details of the esc blowing? What ESC and Motor did you have in yours?

[G Doggett]

Hey SJFE , rip out that single motor mount and shaft and treat that beautiful boat to twin motors and drives !!!!!
Its the only way to go.
Twice the hassle but twice the fun.

rip out that single motor mount and shaft

Sorry man No can do. I will leave her as she was intended. If I come into some money I'll just buy a twin. I know i'd mess it up in the process.

My rotor arived today. Great work by Peter Z. Just by chance I happeded to finish the esc today. The mold popped off the esc in a snap. I sanded it down a bit. All thats left is the cooling plates. I am going to make a better fitting one for the next esc. I'll be testing on Sunday.

`that esc will weigh a ton

[SJFE]

150 grams and change. I'll shave it down more today.

[Steven Vaccaro]

I dont think the weight will be a big issue in that hull.

Id say its w/p now!!!! hope it will dissapate heat. Abit overkill on the epoxy???
Maybe say by 1/2 a tube lol?? I just had to say it lol

I was always told a non-porous surface does not dissapate heat. However a wet esc does not create a happy SJFE!!!!

Have you guy's tried MG chemicals Conformal Spray Coating??

I have used a spray by MG chemicals,,, It is a conformal coating for vibration and water resistance,, much like the stuff Castle uses to waterproof thier esc's... I really like it, because it is easy to use, dries in 2-4 min.., and I have gotten a couple of these GX-200A esc's wet, and had no problems at all!!!

All I do is open it up from stock,, spray it with MG,, build a watercooling plate from K&S brass tube and plate,, then re-heat shrink it....

I like SJFE's idea of total encapsulation... Reminds me of SV27 esc's and Kontronics Power-Jazz....

I cant wait to hear some feedback on how they perform.... Any testing SJFE???

[SJFE]

I am testing today but the Jolly s not ready. Just the little twin cat. The DP270 is a heat transfering epoxy with some good exotherm ratings. When I was sanding the bottom the entire block heated up pretty evenly. I should have it ready and tested by the middle of the week. Just waiting on the 70K Boca bearings for the KB.
