Default Help- electric conversion - Zero fighter

Hi Folks,

Just returned to the hobby - after 25 years - few months back, with a nitro powered airplane. But recently found a 1987 Kyosho "Zero Fighter" which has never flown before. The stock powerplant is a LeMans 240e motor.
I am going to attempt a brushless/ Lipo makeover. Planning to use a Turnigy 2213 20T 1050 Kv with 3S 1600 Lipo.
It will be great if someone who has attempted something like this before can offer tips/ ideas.

Cheers..

You have provided no information about the plane so we have no basis to help you. I know nothing about that plane.

2 pounds, 20 pounds? 30" wing span? 90 inch wing span?

Wing span and weight would be helpful.

Why did you pick that motor?

Note that nitro planes are typically built much heavier than electric planes. They have to withstand the vibration of a glow engine. Electrics don't place this stress on the structure so electric planes can be built lighter.

You should read this thread:
http://www.wattflyer.com/forums/showthread.php?t=31071

The first benchmark would be watts/pound of all up weight.

For something like a fighter I would recommend a minimum of 75 watts/pound for sport flight and I would probably target more like 100 watts/pound. So, if the all up weight will be around 5 pounds, a 500 watt motor/battery/prop combo would be a good target.

You can do this with an outrunner or an inrunner with a gearbox.

This is all described at the link I posted.
