Rebuilt heli not flying right

[aaron-88]

hi all

right i have finish rebuilding my copterx 450 ae v2,(after a nasty crash)
i have put hxt 900 cyclic servos in, an overlander xp40a esc align main gear set,a cnc alloy head and tail holder.i have left in the standard gy240 gyro but have got a s9650 tail servo.
i only have the standard tx which i cant change any settings on without a computer,and all i have is my ipad.
when im flying it is not behaving like it used to, it seems more skitish and the tail jumps around if i touch the rudder control.i have got the old woody blades on as i am waiting for a set of carbons,the swash is all level pitch seems good,just cant figure it out.also my tx does not have a switch for hh!!very frustrating!

any help welcome.

..always difficult without a programmable tx... but I'd start by measuirng your collective and cyclic pitch ranges..may be too extreme..in which case shortening the horns would calm it down some..

That must be one of theose displayless txs where everything is programmable, but adjusted via USB and a laptop?
So a cheaper tx
or a £600 tx if you include the laptop cost!
