Default RE: battery hatch

Nice hatch! Great idea removing all that ballast. I make electric powered airplanes only and with electrics you NEVER add ballast , just shift the battery pack to balance the plane.
I agree about the ballast thing. Unfortunately, this plane has a very short tail moment and when it was new I didn't want to do the surgery because the finish looked really good. Now that it's been beat up for a couple years and it's the only plane I have flying, I decided that it had to be done.

If repairs, revisions and updates = character, then this plane has tons of it.

A brief history:

It started life with a wankel. The wankel was a gas guzzler, so I switched to a webra .32. It was nose-heavy then, but the Webra's idle was too rich and it couldn't be leaned any more. So I swapped to the next bigger engine I had - an O.S. .46. That's where all the tail weight came in. The plane will accelerate going straight up, but that's all I can say for it. It was so heavy, it was a total dog. I hated flying it.

I put the wankel back on, cut off the stab and elevator and dug out all the lead shot, swapped 4 servos for lighter one (Futaba S3002's to Hitec 255's)., smaller wheels, etc. Haven't flown it yet because the winds today were really bad. Hopefully tomorrow.
