Default RE: Composite ARF 2.1M conversion


ORIGINAL: Paul Eagon

I have been flying a 2x2 on electric now for about a year. I am using a Hacker A60-18M with an APCE 24x12 and 10 cell 5000mah lipo's. Speed controller is a CC 85. Max amp draw is 75 and I am producing 2600 watts.

I painted the basic plane with base coat clear coat with color change trim, so it is about a pound heavier than normal. With the 5000mah lipo's, it weights 16lbs. Tha calculates to 162 watts per pound. I have a DA-50 version that weights 15lbs.

The power to weight ratio is good for IMAC and light 3D. It will hover but the pull out is ever so slow. 12 cell would cure this but I am satisfied so far and like flying it. If I want staight up crazy power, I fly the DA version.

I placed the stock firewall where it needed to be for a DA-50 in case I decided to go back to gas. The Hacker adjustable motor mount worked great.

Don't worry about tail weight. I have two 8411's in the back for elevator. To get the recommended cg, I actually had to move the lipo's back as far as I could under the cowl and still be able to reach the rear hold down strap. I have the 6 cell radio battery just behind the firewall and should move it back under the canopy but I have not got around to it yet. The front of each 5 cell lipo is about 1/4" in front of the firewall.

Paul how long is your flight time on the A60? I'm planning my set up for a A60 14L and trying to decide on 5amps or 8.
