Spent the entire day making rubber braided motors for many of the planes I will fly Sunday at the Grassy Knoll.
George made me up some 3/32 rubber for his Volare Model Products Peanut Corsair kit. I think I added a gram of led to the nose and the CG is a bit aft of the recommended location but it flies great there for some reason.
The motor is one strand, one loop braided. I’m starting to get the hang of motor making after a year of the craft learning from the masters.
I Made up motors for the Breda 88. Trying at best to get them both the same. Very important with a twin as you need to have both motors putting out the same thrust. In addition to that they both need to wind down at the same time.If one keeps running loner that the other and you can have a wing over death spiral.
I managed it.
Mystery tailless has a new braided motor also made from Georges 3/32 rubber. I thought the recommended 1/8 rubber was a bit much for the fragile airframe.
The test flight I had at sunset in front of our building was just amazing she just flies perfect every time landing on her wheel.
BF-109 got a new motor. 1/8th , two loop braided.
Most of these motors are all low starters for the maiden and trim flights. Later on I will slowly increase. I have learned a lot from all this especially when first testing with an unbraided single loop to a braided 2 loop or even a single.
It takes more winds to get the same torgue off the bat as you do with a single loop unbraided. I had to wind the braided motors a great deal more to get that punch on launch but got longer flight times and less CG shift. I’m still not there yet but as I kept yelling out to Mary yesterday, “I’m getting better at this!”. 😉
As always keep a log book with a listing of what you did to each plane.
