I am building a hk 450tt flybarless and have run into few issues.

3 screws on the fibre housing refuse to budge and i am not able to put the boom support and landing skid. any idea how to loosen them?

i have got the turning tgy-306 for the tail and its a smaller servo than the servo holder given with the kit? is there a way to get around that?

thanks for your help

Apply heat to the screws going into the metal to loosen up the threadlock and then remove .

For servo you'll need tail boom servo mount from V2 or something with new re-sized Links.

What gyro you planning to use ?

Thanks, I tried heating as well it helped for some screws not for all.. I broke my hex driver to do that as well .
For the flybarless control I have turnigy v2 and mini fu bar sent free by HK. Can we source tail boom servo holders locally? Thanks for your help..
