I purchased this power system for the FW 90mm F-16. With the impressive performance of these 9 bladed setups, I was hoping for moderate performance for my F-16. I tried a 4000 70c, 5000 55c, 5200 90c, 6000 50c, and a 6200 50c. No matter the fuel delivery behind this edf and motor all results were full throttle, full length field runs while jerking her into the air at the departure end. Climbs are accomplished at 10° to 15° nose high and anything less than 70% throttle results in a loss of altitude. I'm sure this would be great an another bird, but the falcon weighs a ton.
Initial testing in my fly fly f86 shows good power and great jet like sound. No balancing or vibration issues to report. Have not had a chance to fly my old F86 90mm as of yet. There was not enough room in this jet to install the tail motor cone so just left it open. Will report further after maiden flight. So far so good. Must comment on the prompt delivery to Canada, less than 2 days. Very satisfied with Motion RC Service and products. Also bought 2 F104 70 mm Starfighter and a70 mm 12 blade fan upgrade which works very well in this jet.
Excellent service overall, good price, it will be great if each item has some illustrated instructions, (e.g, wiring and connectors on edf, esc. Etc) it will really help people who are switching from gas to electric or vice versa.
This motor fan combo was a great upgrade for my F16 90mm. It reduced the full current draw from 130 amps to 108 amps keeping my batteries cooler with little flight performance reduction. Sound is a little different but not much.
After flying the Freewing F-4 Phantom with this power system I decided to install it in the Freewing F-15 Eagle ARF I recently purchased. My F-15 can takeoff in 100 ft and that’s with my wheels tightened. If I loosened my wheels and greased them I’m sure I could reduce the takeoff distance to 75 ft. Top speed is excellent and vertical performance is excellent. I posted a couple videos on YouTube and more are on the way. https://youtu.be/Ru_kHa_J4dY
