Leopard Hobby 4282 motor

[slick2500]

So I recently picked up one of these https://www.rcjuice.com/motor-esc/b...brushless-sensorless-motor-for-1-8-scale.html from @RCJuice and when I went to mount it up to my motor mount I noticed that this motor only has M3 screw holes. I know I can't use M3 screws in the motor mount so now I need to either find a spacer to make up the space or drill and tap the motor for m4 screws. Who makes a 1/8 motor with just M3 screw holes in it?

Not familiar with the motor, I haven't replaced mine from stock yet, but I would think it would be better to drill out the motor if you can than to use a spacer on the screw. A spacer means there's still a M3 holding the motor.

Bummer! That is odd that they set such a large motor with m3 sized screws. I like Leo motors, might be worth the effort to tap it?

My Castle 1515 2200kv came with M3 holes as well. I drilled and tapped them for M4 screws. I thought it was really strange that it came with 3mm or that it didn't have both sizes. Oh well, I have the taps so it wasn't a big deal.

Need to tap for m4.

I don't have a tap

Do you forsee the need to use taps more than this one time?

Not really lol

Not really lol

I can go to the post office tomorrow to see how much it would be to ship them to you and then you would just have to pay the return shipping. Would that work for you?

I might just get this kit https://www.ebay.com/itm/M3-M6-Machine-Screw-Metric-Tap-Reamer-T-Handle-Wrench-Twist-Drill-Bit-Set-BI656/143280607406?epid=8016094001&hash=item215c3090ae:g:jsIAAOSw7CBc9adW&LH_BIN=1

It’s really handy to have a few taps, their drill counterparts on hand and a pin vise or old drill chuck to hold the taps. Some times when you get new arms or bulkheads it helps to tap one or two turns to get the screws started.

Not sure if this lead to the pinion coming off or this is a result of the pinion coming off. I only had a 18t pinion on it.

That is pretty hot for a leopard of that KV and size. What was the ambient temp like outside?
How much does that rig weigh? I see lots of aluminum parts there.

I have been running this week and the temps reaching the 90s made a massive impact on motor temps...

It was mid to upper 60s.

I'm not sure but it's pretty heavy. Once I get a new spur and pinion I'll give it another go but maybe I just need a bigger motor.

 

[Wmorgan]

That's a hot one!! ?

 

[slick2500]

This is really starting to piss me off..............And of course I can't return it because RcJuice won't accept motors that were overheated..........................
Not even 2 packs through this turd. That's $80 down the drain........................

So who has a suggestion for a motor. I will not buy another one from RcJuice. I don't really want another BLX185 either.

What about changing to a smaller pinion gear to help it run cooler? No heatsink or fan for the motor?
