Thanks, guys. These are all great suggestions.
CP, I weighed the wheels separately. There are classic DuBro 2'' treaded (2.00T) - 1.3 oz for the pair. I could save an ounce right there by switching to ultralight foamies.
As for the radio gear, I did just order a new NiMH Rx pack, but of a higher capacity. Still lighter than the 270maH NiCD, but only by a couple of grams.
The receiver is what came with the radio set. I am also looking into what auction deals I can find on a lighter 4/5 channel Rx that is compatible.
Servos are pretty much installed. The mini's IĀ*chose weighed lighter for 3 than the original 2 std. that the plane was planned with. I wasn't sure how small/light IĀ*could go with them. I might do this in the future, but would rather save the $$ right now and the time of ordering and re-installing smaller ones.
IĀ*may eventually build up a balsa wing for this plane. But I would like to get this up in the air for my son, before he loses interest.
What about removing the case on the 8CH Rx? Is there much of a risk, and does anyone know what the weight savings might be?
