I recently purchased a Hobbico Superstar 40 ARF. The engine mount is already attached to the firewall. The engine attaches with 2 plates and 4 screws. I've been reading alot here about having some thrust angle with the motor. This mount doesn't seem to have any. The instructions doesn't mention it either. Should I put an angle on when I install the engine as the plates give you room to do so, or just put in on as straight as I can? Also, what's the best way to make sure the motor is aligned correctly> Do you measure from the tip of the stab to the tip of the propeller? Any help would be appreciated if anyone has ever flown a Superstar.
