I would be really interested to see the inards of that TS2. How it is setup, location of esc, battery, reciever, length of cables etc? Thanks for that vid.
Anyway, here's a short vid of a MAC .21 powered tunnel to compare to the electric version. Maybe a 2215 BAM would do the job? I don't think I could get the EP1 to these speeds though, lol.

It was a very windy day.[:@]
