I have a question regarding witch motor and ESC I need, the plane is http://www.nitroplanes.com/new204chathi.html the A-10 it came with 2 duct fan 370 motors. I don't know what these are rated for as far as RPM but there not enough. basically I know that the KV number is the no load rpm at 1 volt but I don't know how much motor I need. also I need to know if I need to run 2 ESC or if I can just run both brushless motors off one ESC like the brushed motors that are in the plane now. I'm guessing for the application I'm using them in (duct fans) they will have to be inrunner motors. any knowledge and help will be appreciated.

I have the same plane--grossly underpowered. How do I change motors. I have a park 370 brushless inrunner, can these be used. If so how do I get the old one out.

I'm giving up on the A-10 after crashing it. its pretty much junk. I could try and glue all the pieces back together but the quality of foam is so poor that the smallest incident seems to remove the biggest chunks of the plane. I'll chalk this one up to the whole if the price is too good to be true it probably is theory.

Hey, you still have the Transmitter, servos, receiver and speed control so it is not a total loss.
Pick up an ARF that comes with a motor and put your electronics in. Foamy ARFs aren't expensive.

good call!!! I think its time to go to the hobby shop!!!

If you wnat a fuller understanding of electric power systems, take a look at the TOC of this e-book
