I have not heard of the Align 35X causing that issue but it's not out of the question.

What size/capacity batteries are you using and how long were the 5-6 flights?

Make sure the main rotors spin freely when you turn them by hand, you should get at least 3 full revolutions when you spin the head.

Post your 35X programming.

im going to go back through and re program.

this is how i plan to set it up..
BRAKE- DISABLED
TIMING- MID TIMING
VOLTAGE PROTECTION- HIGH
AIRCRAFT- SOFT START HELI (NO GOVERNER)
THROTTLE RESPONSE- MEDIUM

not sure about the settings. i have a 430L 3550kv motor

should i run high timing??
governer mode locks throttle at one speed correct???
would i benefit from faster throttle response???

I'd run mid timing and high throttle response.
1-2-2-2-3 is my setup.
