I've had this half completed kit around for ohhh say about 15 years. I might get around to finishing it soon. the question is can it be converted to Electric? easier to find a electric friendly area than a gas, no tuning needed for various temps, etc. Flight weight is only around 5 LBs. I have zero doubt the batteries I had are now shot to hell for holding a charge after this long for the ol' JR ProPo radio system with 4 servos. So I plan to replace that with a Spektrum DSM2 system, support for both plane and heli would be great. Also have a Heli airwing, a CX2, and a MSR(coming)

I have to pick it all up from storage and bring it home. a few busted wing parts that should be easy enough to repair/replace. Finish construction and cover.

Should be easy to convert to electric. Lots of trainers(glow) get converted.

I'm pretty sure there are a couple of these conversions in thee "Planer Ratings" archive of the Ampeer newsletter. a terrific resource for conversions.

A little shameless self promotion never hurts

Looks to be costly.. hmm.

I am looking to do this conversion as well, but I want to buy the ARF. I had the kit originally with a cheap OS engine that ended life after hitting a tree. It was the best flying plane, I had even added flaps. It would climb amazingly. Great on skis and oversized tires. Please help keep this thread alive!

Any idea what would be recommended for motor size, esc, and batteries? I'm assuming LiPo's, 4 or 5S even. I see Hobby City has an 'L' mount for helping convert to electric for this style engine bay.

I crunched some number through Scorpion calc and this is what I came up with:
Motor: 3020-780 weight : 5.93 oz.
KV: 790
Io: 1.487
RM:.0317
Using a 4S pack and 12X6 APCE prop:
I= 39.57 Amps
Power In: 585 watts
Power out= 460Watts
Thrust= 78.9 oz.
prop Speed 9560 RPM
This is a ball park figure as actual number will vary slightly.
You could also use the 3026-710 for more kick and a little more weight to help balance the plane. However with this motor combination there should be more than enough power for the plane, close to 100W/Lb.
good luck!
BTW I flew one of these using a Mega motor/gearbox combo and round cells several years ago lotsa fun.
