Aeromarine 43" Challenger pro gas to FE build

[Spot Me 2]

Hey guys,

I have been out of FE for a little while, but due to too many noise complaints....no more gas running.

I recently picked up a 43" Challenger pro that was a gas boat. I am going to convert it to FE. I only do sport running and I am looking for scale-ish speeds mid 30s or low 40s.
I ordered an Atomik V700 Marine Outrunner and a seaking 120 amp ESC. I will be running on 6s. I need help picking a prop. I only have big gas props. I know Atomik runs a 54mm 3 blade on their 58" cat with this set up. Is this a good place to start?

This is what I am strating with...

Hello,

I just finished building a 41" boat which was designed for gas and made its conversion to FE. It was my first build but you may find usefull information equipmentwise and some other tips.

Good luck with your build!

Fwiw, that is a VERY small motor for your boat. Venom didn't do the best job rigging their boat with gear.

agreed...

I agree with the above post.

Go to southriver rc and get you a good 5" motor mount. That's what your rails look like. And get you an inrunner motor some thing in the 56mm diameter. And something with a kv in the 8s area would push that boat great

I here what you guys are saying. I'm not looking to set the water on fire. I am trying to use what I have already. If its too slow I can always upgrade. I was thinking of a proteus x524 if and when I do.

a slow running boat is a wet running hull
wet running hulls pull lots of wasted amps.... = heat
and a hull this size, well ....

and the motor from venom is marked up about 3 times

The Proteus 56MM motor was only about 10bucks more with possibly 4 times the power

the Leo 5692 1340 motor could be run on 6s like your after and with more power than the venom

I didn't pay that for the motor. I paid $50 shipped for a brand new one. Maybe I will just use it in a different boat cause I just ordered a Proteus 520 and a southriver mount. That should run on 6s with room to grow. Now, on to the prop. Whats a good place to start?

Here is a quote on props. for this size of boat from fellow boaters:

"Probably up to 65mm 2 blade max. You could try a X457, X460, X462, X465, X460/3"

I will be running on my 42" boat a 52mm and a 59mm for starters.

With the proteus 520 depending on what voltage you run it on. Of not start any higher than p 55or60mm prop

Nice looking boat,
I have that v700 motor,
And want to try it in my 36"pro boat shockwave modded to FE.

I am still planning on just 6s. I already have those and the esc can only handle 6s. My plan it to run it on the delta/1280 setting.
