I know a few of us have one, but I couldn't find a thread already in place.
I've only just got around to assembling my replacement airframe kit after having it boxed away for over a year. The details of the power train ....
Motor: Turnigy NTM 3542 - 1000kV (http://www.hobbyking.com/hobbyking/s...00KV_700W.html)
ESC: Turnigy Trust 45A (http://www.hobbyking.com/hobbyking/s...arehouse_.html)
Prop and hub: Durafly P-51/P-47 which from my measurements seems to be a 10x6x4 but it hasn't got that indicated anywhere, so I can't be sure.
Batteries: 3S 2200mAh Nanotech
Static test result: 38 Amps, 1400g thrust
The plane is just a fraction nose-heavy with this configuration, I've got a little moving-around to do to correct that. Overall performance is just what I was after - it's not a bullet, but it has acceptable top speed for a low pass and climbs really well. It's not really that efficient because I think the top 15% to 20% of the throttle movement results in more power consumption for practically no return in either speed or thrust so I might make an end-point adjustment to save the wastage there. Predictably, the heavy prop on a 1000kV motor results in a tendency to roll to the left just after take-off, but once you're ready for that it's easy to deal with - certainly not a hazardous problem. I wanted to use the prop for its semi-scale looks. The Durafly Mustang and Thunderbolt have 750kV motors, which is probably more sensible with this prop - I might experiment with a change to the motor one day, but for the moment everything is pretty good so I'll leave it as is.
A great model and all the things I've read about it over the past couple of months are verified in my experience. I wish I'd put it together months ago.
The next thing to do is do the flap mod and then an individual paint job. Here's a couple of shots of the business-end with the prop on display ...
