"Meanwhile I have the pixhawk, and without changing the servo frequency (I wasn't able to find the menu) it didn't fry my $3 HK analog servos. So you can :)"
"Looks pretty neat! Is the thing on the bottom side (that's connected to the helical pinion) a clutch? Sorry I don't know anything about that since I've only flown electric.

"I just measured the main shaft of my Trex 450. It's 5mm... You could change the bearings which hold the shaft, and you'll need to find a gear that fits.
Interesting thing that they try to increase efficiency with bumps. But I think this is a long…"

"Wow 30 degrees is HUGE!! A typical (model, 450-size) helicopter has 12 degrees of pitch (both positive and negative 12 deg), or maybe 14 degrees if you're really badass. I'd say go to max 12 and see if it'll hover. If not, larger blades! Make sure…"
"Hm I checked some flight logs from a while back, and you're right! The asymmetrical blades do not appear to be more efficient (headspeed 3200 rpm on trex 450).
So how about flat bottom blades? These are used a lot in model autogyros. With…"

"This is cool! I have 4 years of helicopter experience, and limited tricopter experience.
The thing with multirotors being so popular, is the simple mechanics compared to that of a traditional helicopter (with swash plates, tail drive gear, etc).…"

Hi,Currently I'm looking at PixHawk to autopilot a Techpod drone. I can't seem to find whether the pixhawk supports analog servos, which run on 50Hz. I'm asking this because a lot of FBL systems for helicopters have no analog servo support.Does…
