That's why you need a bigger diameter prop in front than in back and a psru to run it.I meant the accelerated flow. A typical prop in cruise accelerates the air backwards ... a 15% velocity increase leads to a 32% higher fuselage drag.
Hello again,Care to post pictures and provide specifics?
engine-> connexion with driveshaft -> spline connexion to PSRU with rubber absorbor (flector)Looking at your first picture, is that a drive-shaft in the middle in navy blue color?, seems like it's a steel car type drive-shaft, what type of coupling do you use, do you have a picture of it?
i have bought thes drive tree / PSRU from shirl Dickey for e-racer but before using i have check and open the psru and done some small modifications: calculation of all gaps and grind metal steel ring to adjust exactly the position inside psru of all elements.Thank you - that's a first. I don't think I've seen a remote mounting of this sort before. Looks very interesting. Does the gear box lubrication work with the engine's?
gear box come from "CASALE" (www.casalev-drive.com)....and what is the reduction ratio (engine cruise RPM)?
Also, what does the all up powerplant weigh (engine, drive, fluids, etc)
