Is anyone out there flying this model?
What setups are you using.

I have one fitted with a TT46Pro engine and 10/7 APC prop but it seems very underpowered.
I'm not sure whether it is because the tank is so far back from the engine (I'm not using a regulator or pump).
I run 15% Nitro / 3% Castor / 17% Coolpower fuel

I just want some speed out of it but can't seem to get it with this motor - I've tried a few different props.

Any suggestions?

I have a spare ST51 and a few Saitos (82, 56, 65 & 72) that I could use on it, otherwise I may have to get a bigger engine but I am not sure how easily it will balance if I do that.
