@NoFate94

I ended up removing the retracts and going fixed gear, seen in part 3

just wondering , did u glide test it before adding the electronics or did u just guess the cg? no disrepect intended just wondering is all

[kwahyttam]

@vtran1000 Yep, I glide tested it long before I tried this takeoff. I also calculated the CG, but this attempt was not a CG problem, it was a landing gear issue.

Been there done that. My observations are you had flying speed - plenty by my count. If your main gear is too far rearward from your CofG the B2 is a bugger to rotate - it's very short coupled. I fly a 10' er and went through all the same issues

thanks for the tip! I think I am a bit nose heavy. I gotta recalculate.

[MinfangDuan]

it looks underpowered

Lookin forward to seeing that huge thing in the air! I had similar issues in the past...my nose wasn't higher than my tail....couldn't rotate on take off....

damn

well better than the landing gear falling off in mid air then loosing them

allways look on the bright side of life lol!
