Shockwave36 Conversion build

[saleens7]

Im in the middle of a conversion using the SW36 hull (the old nitro in it just never ran right) and so far i have the motor installed, the esc is ready to be put in, and im only a few bucks away from buying the batt's.

it uses a Quantam 36x70 BL motor and a welgard 100amp esc. It will be powered by 24 IB3600 cells.

looking good, will your esc be water cooled?

[saleens7]

yes, im going to take off the covering and glue on some cooling plates with some thermal epoxy..

There have been some people playing with that motor on other forums. Their experience hasnt been good. Start with a very small prop with that motor.
Take baby steps.

im only using a 40mm prop right now...it looks pretty small....

[Mich. Maniac]

the reason i ask about esc is I want something about 100 amp for my motors but want it water cooled, so far only thing i like is bk9920

[saleens7]

should i replace the current motor with a feigao 14XL? ive been hearing bad things about it, not just from Steven, but on a bunch of other forums..

also, ive been told that i should grind out a small flat spot in the shaft to give the coupler's set screws a better grip, but ive been having trouble....the shaft it alomost indestrictable..ive been trying to grind out a flat spot with a file for hours and have been pressing on the shaft so hard when i do im afraid ill bend it...and so far, the most ive done is scratched it...the coupler has two set screws at around 120* from eachother, would that be enough to hold on to the shaft or will it just spin? i know people who dont put a flat spot on and the coupler never comes loose on em and they use high power setups, where others couplers wont even stay on the shaft longer than 2 second nless they ave a flat spot...im kind cautios about going at it with a dremel too.....is there another way to cut a flat spot in the shaft

Saleens,

What type of file are you using? Try a mill (bastard) file. Designed to be used in one direction only. We use them to sharpen concrete boring bits, and they should work on your shaft. In fact, I used one to file down a DeWalt cordless motor shaft, so I could get it to fit into a 5mm coupler. I powered the motor up and pressed the file against it, and shaved it down in just a few seconds.

ok, ill look for one...

just wondering...im getting a 3 channel futaba FM pistol radio, but what do people use the 3rd channel for?

[Rex R]

if you get some medium strength threadlocker and a tight coupler it can be a challenge getting the coupler back off the motor shaft...I needed a propane torch, fortunatly I was able to pull the motor out of the boat 1st :)

[saleens7]

i found a big file a filed away and eventually i got a small flat spot...i hope it holds..

im getting a 3 channel radioi system...what would be the purpose of the 3rd channel?

[DuckOfDeth]

3rd channel can be used to activate 'drag chute' or to turn on 'interior fire sprinklers'

Duck!!
