Thanks guys. Its by no means blistering fast

The last two pases in the video are on 8 cells
The first are best with the 12 cell batt still charged.

Im using those cheap 6 cell chineese batteries that are included with the RTR sets.........they are kind of CRAP :-)

I have ordered some proper 3300 Nimh pack for it.

How can it be tuned further ?
A metal prop?
Same size as the one I have on now?
How do i tell if I need a small/larger more/less pitch prop ?
