Glacier, thanks for the specs. It gives me something to shoot for when testing mine. You've got plenty of thrust I'd say. Nearly 4 lbs of thrust!
If you haven't posted pics and specs of your retracts already would you do so?
That would look so cool that I'm considering it if price isn't too much and set up not too difficult.
Did you go with larger diameter wheels incase you land off the pavement? I tend to miss or overrun the runway on occasion.
