I'm using an airstart olympus/AT450 and can attain proper CG w/o lead. I'm using (2) 3600 NiMh batts for the airborne system and a 2000 LiPo for the ECU.

I think you'll be ok with the required air for the engine. remember the engine is going to draw the air from wherever it can. the inlet system in the jet will provide plenty of air for it to draw from. However, if you're seeking smoother airflow to the face of the engine then consider moving the engine back slightly.

my engine inlet bellmouth bisects the front engine mounting former. i.e. front case fuel, air, propane fittings just barely reach the former.

Hi Guys.

I'm putting my old air start AMT Pegasus into my Boomerang XL.
As it's a heavy lump, so I'm positioning as far forward as I can to avoid excess lead in the nose.
Trouble is, there is only a 1" gap between the turbine and fuel tank.
Is this enough clearance for the turbine to breath properly ?

The tank is securely gripped by its neck and cannot move aft.

Thanks.
