After riding the raptor 2 hubs on 12S (up from 10S originally) and prolly harder than I should I noticed that the hanger was to hot to touch. This was only after like 10minutes of riding and up some not to steep hills of 1-2km. I have the Motor amps set at 60A and battery at 40A running sensored FOC with escape and a 12S4P samsung 30Q battery.
I then decided that I had to make a custom hanger with more alu, bigger cooling fins for increased surface area and bigger area towards the hubs to absorb heat from the hubs better. I designed and milled these over the last two days. I’m new to cnc machining so it’s a rough prototype with some machining errors that I’ll sort out later. Also I don’t know much about hangers/skating in general so if you see anything stupid don’t hesitate to tell me cause I prolly don’t know that I do something stupid Any helpful design tips is also welcome. I’m guessing that if this design can be improved further it can cope with more amps
These images are done approx 15-20 minutes after riding. The ones with custom trucks where taken 12-13 minutes after riding and that was after riding a lot harder. The shots on the stock trucks was after consuming 58Wh and the custom ones I consumed 89Wh and had much more full throttle pulls. It does look like it helped a lot and I noticed it very good when riding that I can now touch the truck without burning my hands but with the stock I couldn’t hold it comfortably.
The last shot of the motor at 63°C is after going uphill hard on the throttle for the third time on the same hill. After doing that hill two times with stock hanger I couldn’t hold the truck. Now the hanger is warm like the motor but it doesn’t show on the thermal images as I forgot to bring tape and alu is reflecting to much throwing the camera off ^^
And some pictures of the hanger
And for the geeks some shots of the machining:
