blade 400 tail wag....

[recker69]

i have a blade 400 and i started to get alittle tail wag on the first flight after a very minor repair of a main shaft and a fly bar. im pretty new to helis so i could use alittle help.
i also have a guestion about every time i make a input on collective i have to slightly throttle up so i can maintain a consistant hover. i dont know if thats normal or not. it seems to me that the extra load on the motor from a input would mean that the esc can not flow enough amps to keep up?

hope over to the b400 section

but repair means fixed a bent or replaced?

and yes in normal mode the rpm will change at the same time collective pitch changes. idle-up is more of what your thinking a constant rpm only thing changes is the blade pitch. its the upper left switch. recomend being very comfertable flying the 400 before you rune idle up since if you go down droping the stick will not stop the motor. you have to know to hit the TH hold as quick as posible.

but vibs can be trick

most of the time it can be anyone of the shafts or all of them. blade tracking flybar tracking. belt tention.

hope over to the 400 forums thiers a running vib thread now that may help
also a b400 bible that will also answer lots of questions
