BobCat downthrust?
Hi guys.
I'm doing some preliminary CAD work for a DIY "BobCat" and was wondering if the BVM BobCat have the turbine dialed in with some downthrust? I would assume there is but how much?
Also whats the wheelsize used on this jet, for gras ops? From the 3views the mains seem to be ~60mm.
Any help would be appreciated.

Gracias Jesus 
So the stab is set to +2deg relative to the wing? Would account for some of the high pressure area (exhaust) under the stab.
Info much appreciated!

RE: BobCat downthrust?
Haldor, all the angles are refered to the wing airfoil axis. To be honest I never understood wery well this set up, but my BobCat with a P-120 doesn't experiment any changes in fly at full or at idle.
Sorry I can't help more in this question I am not expert in aerodynamics.

RE: BobCat downthrust?
Harald, the front tube is 7/8" and the rear 3/8". I don't know the thickness because my BobCat is scratch built from plans and I have fitted 22 mm. and 16 mm. with 1.5 mm w.t. I guess that the english size is about 1 mm. w.t.
