HD Goblin and Low RPM

YouTube Preview Image

Here is exclusive info from Phillip regarding his heli.

Everyone seems to only think Goblins are only good at high RPM hardcore 3d, but a bone stock 700 can be flown with just 6S @ 1200-1100RPM just fine 😀 The head wobble range is between approximately 1400-1650RPM, below the heli flies just fine again.
The heli in the Video has a X-Era Goblin edition 500KV motor, Heli Jive 120HV, AR7200BX and Torq Servos and a 6S Turningy 4500mAH 30C Lipo. The main blades are MS Composit Rapid 710mm, the tail stock Goblin kit SAB tail blades. I use the Kontronik jives internal BEC and a Spektrum DX8.

Flying time about 6 minutes for about 2500mAh used.

That was one of the first trials of flying low RPM and i had setup the throttle curves for three different speeds but hadn’t realized that my normal pitch curve was only -6° / 0 / +12° because i usually only use it for spool up. That made for some head scratching as to why the heli didn’t climb inverted until i switched to flight mode 1 where i had -12 / 0 / +12 😉
