Nothing wrong with using the packs liek that. If you can get more use out of them with split packs go for it. I made up packs like that before (a pair of 2s packs) so I could run them in a 1/10 buggy at 2s or in my 1/8 at 4s.

The Feigaos are so cheap relative to the whole brushless project, I would not see the problem in planning to do two motors. Especially if a guy even thought for a second about getting a Lehner.... that $$ would buy like 4 XL motors...

If you want one motor... get 9XL. It's a good fit for your 50mph on 6s... and you can make do on 4s while waiting on the MMM. Gear it 18/46 and it will be very fast.

Seriously, I think you will find out that 50mph is overkill.. not that it's not cool... but low 40's is very fast and still jaw-dropping for most people.

Get some video if you have it running 50+..... I never gear mine that high so it would be neat to see it.
