RE: Magic Formula 3D
Slimm
Go for a larger battery pack, as has been said b4, the weight might as well be working , rather than lead.
Recommend you change the piano wire on the rudder pull pull its way heavy and there is nearly 6 feet of it .
if you save an oz on the back you will save 3 or 4 on the front.
you could change the servos on the elevator, to SD250 mg's, that change will save you 2 oz on the back,
And at 6 volt they run very close to 4kg pull and .10 speed each.
That 3+oz saved on the rear will remove most of that lead from the front .
On a different note I have just found out the Saito 91 with muffler is 10g lighter,
than the Irvine 53 with muffler, 520 v 530 grams, hard to believe
