Default RE: 3D Hell Raiser

For all those flying this with the recommended hardware from HL, set your Jeti controller to HARD TIMING... it is recommended for the AXI motor, and boy this thing must have 15-20% more thrust now... hard to judge, but hover was around 3/4 throttle, now it hovers at just about 1/2 stick! (using the TP1350, AXI 2208/34).

I guess Mike is busy. He has not commented on our build comments and suggestions. We had to built a third, after TylerMan (my maniac 3D son) splattered his into a heap of twisted crap when he got too cocky. We are getting this build down to a science. It takes about 16 hours to do it right. We have done MANY mods to make the build WAY better. We still stuggle with getting the fuse straight... my biggest beef. Every one gets a little better.

New problem to watch for in flight... I see a "twist" in the top wing at moderatly high speeds, where the leading edge on one side catches the wind and dives and rocks the top wing out of position. When you have this happening, drop the throttle and it will let go and fly right. When it happens, the ailerons won't make the plane respond to roll commands. It took mine in, and it looks like it is due to the weak center cabane, allowing the top wing to twist on the Yaw axis.

We have a new tweak that makes the cabane and wing really tight and this twist almost non-existant. Just take an ice-cream stick and pierce the top wing all the way into the fuse following the back edge of the cabane. Cut to flush on top, and let it go into the fuse 1/4". Then, epoxy the hellraiser out of it. This reduces the top wing twist about 80%. The only way to do it better is to put in more criss-crossing flying wires.
