Loops for the F645 Rotorhead made out of 12x1mm heatingpipe and brassplate

I removed the PCB from the F645 and placed my Flysky reciever, then i placed a GA250, wich has got a wonderfull new Firmware ( https://www.rcgroups.com/forums/showt...=1493174&pp=50 ) then i configured the gyro and went out to fly... and it works! The gyro is very stable in heading-hold-modus, in rate-mode it drifts clockwise, but as the heading-hold-modus is really fine, you donīt really need the rate-mode. The only thing i have to do for now is to trim the pirostops, as the heli sometimes bounces on hard stops.
The heli could be moved very sensitive now with the TH9x, it is such a pleasure now to do exact turns in small places, i could not do this with the original transmitter.
A big compliment to OlliW, who did the job on the GA250 firmware and to all the others, who made the ER9 Firmware for the TH9x and other TX -> they did a great job!

Since the original tailmotor gets very hot and didnīt last long i followed Moki and convertet to brushless tailmotor. The only difference between Mokiīs F45 and mine is, that i didnīt used the BL_Heli software, because the toolstick for programming the controller is too expensive for only one time Programming. I used an Atmel Tiny13 with a software that the user quax had posted in this forum ( https://www.rcgroups.com/forums/showthread.php?t=744929 ) It works fine and the Tail stays very stable. For the motor i also used the turnigy 1811 with a 6x3 GWS-propeller. The holder is build of polyamide
