OK here the pic. That a good ideal to wait till you have the engine mounted before installing the batt and also waldo's set up is more than likely better for you as you will be removing you batt for charging.
Waldo I told the little wife what you said and she just raised 1 eyebrow[] lol. is your us 1000 up an flying because I was thinking with 1500 plus square inches of wing on the tripe wouldn't the big tigre be more fitting IE give her that 3d power. NOw if any 1 out in t---t land want to donate an os 160 fx to the waldo tripe I would bet he would not object that way he could take off with some 1 just holding the plane with the nose pointed up an just let go
Of course I know the 61 will fly her but the 160 would turn her into a space shuttle. maybe waldo could get some work from nasa lol
