I purchased a spare cowl and made a ply firewall to fit a 55 mm O.D. Aluminum Turbo Spinner. A yoke and collet matches it and holds 10x6 folding blades. A bungee ensures positive blade retraction. Extension is symmetrical avoiding start up imbalance loads. Heat damage from the sun warped the black painted plastic and it was removed and replaced with clear .012 inch thick plastic from a pastry container. Canopy glue was used to glue the clear to the white plastic and for screening over the turbine duct openings.

Dive performance with power off is increased due to reduction in prop drag. With a 4S 1500 100C pack amp draw is only 33 amps with 470 Watts of power. On a 20 second full power climb at 80 degrees (SAFE selected On) she climbed to an estimated 1000 ft and after trimming for a 200 ft left hand circle stayed at altitude for 10 minutes power off!

An ISDT BC 8-S shows battery remaining in percentage and in voltage. It can be viewed while running up the motor while straddling the fuselage from behind the prop.

Here is a video of a Twin Mustang in the Test stand. Purpose: to check for unwanted yaw and differential throttle (desired yaw)

I researched the Avios SkyMule thread to look for diff throttle programs and found Oxotnik’s program that reduces the inside motor.

Here is a copy of his post:

I also added throttle curves for both motors. Max Thrust is still available but most of the throttle will be from 3 4 stick position to 0.

I also added throttle cut to both motors using a mix.
