Default Need info for twin electrics


Hey Gang

I am brushing off the dust from a plan I started to do about ten years ago, the RCM 63" Cessna T-50 twin. I don't know much about electrics but I do know that's the power I want. The plan calls for twin nitro 35's. my problem is, in brushless the motors seem to jump from to small to too big. (I guess). I am not sure what motors to use. I don't understand the motors with three numbers on them that are smaller and I think the 45's are to much so any advise I would greatly appreciate.

This will be a "SHOCKING" Journey down the dark "E" power side.

There are few brands that list the size just like the old glow engine numbers.

Here is one motor that would be about right. Of course you will need (2) of them.

Here is a good speed control, ESC, also need 2 of them. It is out of stock right now. They come and go pretty quick.

Another one, also out of stock

This one is in stock and will work.

Here is a battery, of course you will need two of them.

Using a 12x6 prop will give yo more power than the old 35 glow engine would. If it turns out to be to much power, yeah right, you can go to a 3 cell lipo in stead of the 4 cell.


Here is a good online calculator you can use. Pick a motor, change the prop, number of cells, watch how the amps change. Takes a little time to understand how a battery or prop can change the power of the setup. You will hook up the ESC's with a "Y" harness to the throttle channel.
