Default raw - low headspeed

i just started my build. any tips for low headspeed, 1200-1500 ?

are the stock 90 dampeners good or is it better to switch to the 80's?

I've flown at 1500 and had no issues with stock.

They say the rigidcore dampers are way to go for low headspeed, Xguard RC sells them

I have the rigid core’s in mine. Every flight is 90% @ 1960rpm, and finish
The last 10%@1200RPM. Works great!

Default RAW Low Head Speed

I merely dropped my ESC output down and with no other changes went from 1950 rpm to 1300 rpm and it flew great. Video below.....

For a video thatís fine but if someone intends to spend time flying at that headspeed they should adjust gearing accordingly.
