You get more continuous lift at 1/4 throttle because at full throttle you keep getting into a stall situation. The probably doesn't happen once the battery starts losing power. Adding down elevator forces the nose down and aleviates some of the stall. Adding up elevator increases the angle of attack of the wings and the plane will fly slower, so it will not climb into the stall.
Moving the battery forward gets rid of a lot of the stall and you'll climb faster without adding weight.


Since others have posted pics of their landing gear, I figured I will too. Mine was done quite a while ago. I was going to use the landing gear and wheels from and old $2 balsa stick rubber band flyer, but made these out of buttons and pins. I have a choice of 2 hole or 4 hole buttons. I used 4 hole because they're a little lighter. I drilled the center with a #72 bit and pin vise. A drop of CA on the inside edge of the axle stops the wheel from going too far inside. I can easily take off and land on my pop-up camper top.
