This 1/10th Scale B17 under construction
The photo to the right shows the engines mounted ready for synchronizing. Wing is in test bed stand to save wear and tear on the fuselage. The break in on all four engines is now complete and total run times vary from 9.2 - 10.10 hours per engine. About 98% of the test flying was done with a cub on a 16x12 prop. Keith firstly tried a 13.4x13.5 3-bladed prop but was not happy with the results. He then tried a 15x13.5 and a 15x13W 3-bladed APC prop cut down to 12.5" diameter to provide fuselage clearance and prop overlap and has had much more success with them comparing well to the 16x12.
Top Tip Keith comments 'the engines do not care for cold temperatures and are stiff to turn. I solved this by running my vehicles motor and holding the RCV engine to the exhaust for a couple of minutes before starting '
