Pics and video of my Mugen MBX5T truggy brushless conversion...

Yes, I am running the RX8 2000 combo in my 6T. Ran it in my 5T earlier this year. After the whole rotor issues, I have not had a problem in 2 1/2 - 3 months racing a couple times a week. Although my RX8 runs 30 degrees cooler in my 6T.

Thank you, that's really helpful to know - I don't want to splash out on a motor that won't fit!
30 degrees cooler in the 6T? That seems weird... are the 5T and 6T really that different in terms of the power needed to push them along? Is the 5T heavier? Or is it a different drive train like a slipperential that is making the difference?

No, I couldn't find a way - the little cubic shapes that make up the heatsink just stick out too far (only about 2 mm), and it is the metal chassis that they bump up against, so there is no give. It was only by chance that I discovered that in time - I was just about to order a Tork motor as the standard CastleNeu combos are not in stock anywhere in the UK, and as luck would have it I was changing the pinion on my Savage Flux, threaded the set screw and had to take the motor out to fix it... so I just tried it out for size.

I really don't know about the Tekno kit - if the motor is the same height from the metal chassis then it would not; but if it is any higher it probably would as we are only talking about a couple of mm.

EDIT: Has anyone tried the CastleNeu motor on the EZrun 80A ESC (on 5s, geared for 40mph-ish)? Will I regret trying that?

There is a significant weight difference. Not 100% sure if there is a differential ratio difference (I should know this). I ran the Slipperential in both the 5T and 6T. It could be many factors of why it runs cooler: gear mesh on the gears. If the mesh was slightly off, it could put more strain on the electronics. I built the 6T from the ground up, and built the front and rear diffs as per the race specs on the mugenracing forums. The 5T never ran hot at all. 150 tops on the ESC (which is still great). It's just the same set-up is even cooler now in the 6T.

Ah, that makes sense - I am sure that the weight difference and the extra care and attention in the build easily explains the difference in temperature..
