So sat we took the Gem on a High Speed long distance run. Well things got hot and the Motor Magnet let go. I had a 7.5 Hp motor just waiting to get installed. So I figured cool now is the time.
Lucky for me I had a Gem car parked infront of my car that had a perfectly good Vented 7 Hp factory Ge motor
Moral of the story. You don’t need a R4F or D&D motor to go fast you just need to feed that motor some voltage. And I’m sure if I did some more mods I could get the stock motor magnet to survive. But I figured I had the R4F motor I wanted to try it out. I still want to try a good one out.
PS I had a pretty (what I thought) was whine’y transmission. Well 1/2 of the whine it turns out was comming from the motor. When I put the new/used 7hp motor in 1/2 of my gear whine went away
Interesting to see how Steve’s stock motor works as compared to R4F.
Maybe you should invent a better magnet. Issues seem common.
Does shaft have a centering hole to put a pin in.
