KB45 front endbell stripped, now what? - Page 2 - RC-Monster Forums

well, the jb is curing as I type this. If it holds the weight of that big kb after being propelled on 6s and cartwheeling I am going to buy stock in the jb weld company. (Justice Brothers, they make swell chemicals)

see harold, your jb weld could be done setting by now ;)

i think there needs to be a heatsink/clamp for the KB motors. the feigao sized ones are great at keeping the feigaos from falling apart. the better cooling is just a bonus. if there was one for the KB45-xl motors, i'd buy 1.

Me too, but Mike said that there was no plans for one any time soon. I'm sure he would do a custom order, but it wouldn't be cheap.

Yeah, I can imagine a custom one-off clamp for a different diameter motor would be prohibitively expensive. $60 for the motor, $200 for the heatsink - and you still don't have a Neu despite paying the price of one.

I wouldn't think it would be that expensive, but more expensive than a Medusa and one of Mikes clamps for them.

hopefully it will hold. If not, I'll jerry rig a clamp from front to back with some all-thread and, oh, I don't know, chewing gum?

maybe someone can ask make if he can start making and selling heatsink/clamps for the KB motors. the design could be the same as the feigao sized one but bigger.

I can also attest to the power of JBweld. I had two motors with separated rotors, a hv4400 novak and a 1200xl basic lehner (different times but same problem). neither had split, so i JB welded them and they held as long as i had run them. I still run the 1200xl to this day without problems, on 5s lipo. I used the standard JB weld , not the quickweld and the standard will hold to 600* if heat

The std jb is much better than the kwik.

You do need to let it cure for 24hrs or so, but it is near indestructible then...

Thanks linc, I forgot about the 24hour waiting period

Well, this will be an ultimate test for jb weld. The threads were toast, so after applying the jb weld instead of screwing the endbell back on, I just "popped" it baack in with a hammer blow. Thats a 2 pound motor hanging on with nothing but an adhesive! I plan on cartwheeling at about 60mph, so we'll see........
