Looking good - Hope the MM can take 5S for you... There is one thing for sure it will move! Might eat a few pinions - were you able to confirm the motors KV.
Hopefully you can get an RCM hardened 10T pinion that will give you the reight gearing...
Nice! I bet the mail man was probably pretty mad he had to get out of his truck to put the 10 seperate boxes of stuff on your doorstep. Atleast thats how my mailmain is...
