Hmmm - - - - stupid question warning!!!
Wonder why they didn't use your solution on the original?
Any ideas?
(One very nice model is being built - - - literally before us! - - - kudos!!!!!!!!!)
I preferred to do the 1:2 reduction directly after the crankshaft to halve the number of revolutions of the transmission shafts arriving at the camshafts and therefore less noise.
My gears are low quality, not ground on the teeth and alignment is critical.
In the original engine the 1:2 reduction is on the camshafts (bevel gears Z14/Z28) , the gears were of good quality (I think) and turning faster the torque is halved and therefore smaller shafts and lighter gears.
I too would have chosen their solution, but my shop is not equipped to obtain high quality hardened gears....
The original engine has 2 distributors and a double ignition system, like all aeronautical engines, 6 camshafts, mine has only one distributor, 3 camshafts.
My engine doesn't fly, the original does
