essentially a rebadged Axon Razorback from a few years ago.

Looks like this in full flight (not my vid)

http://www.youtube.com/watch?v=5WEBqtYoH78

Power is from a 2225 2000kv Outrunner on a 10A Esc for Lift and a 2225 3650kv Outrunner on a 20A Esc for thrust. Both run through 55mm EDF Fans

Takes a Lot of getting used to, not advisable for confined spaces, in a big open area it drifts well, almost impossible to keep a straight track. The RTR has the two ESC's running off Channel 2 and Channel 1 powers a tiny servo which moves a rudder behind the thrust fan.

I ended up changing the Lift ESC to Channel 3 so it's either off or on, this allows me to do a few more low speed passes without sacrificing lift.

A few vids on Youtube show the Axon going on grass, jumps etc, I find that the slightest bump can stop this thing in it's tracks, doesn't go up curbs, or grass at all, simply doesn't have the lift to do it.

Have a spare 20A Esc and 3650 outrunner, tempted to put them in as lift but not sure if I'll run into issues having the same power for lift and thrust.

run time is around 15 minutes with a Zippy 2000mah 20C Lipo.

As this is light weight, impacts are not really an issue, the foam chassis absorbs crashes well, body shell is made of a cheap lexan which is very brittle and cracks quite easily.

Any ideas on increasing lift welcome!
