I have one(granddaughter),she happens to live in my house,I love that little lap baby,she gives it back too. I used to have some thrust plates back when I flew nothing but 40 size,dont know what happened to them,think I cut them up for something? I just use washers now. I had to go fly after work & dentist appt. last night, it was dead calm. I did more in 2hrs of calm than a whole weekend of 20-35MPH. The Do really shines in calm,I actually got it to inverted harrier a little,thats been almost impossible up to now. I finally got it to pull up from harrier to hover without climbing much, I was on the throttle too much,I was at the hover setting before it was vertical. Now I just do a nice & slow throttle up from harrier,it doesnt take much,just a click or three. I did a few T/R a little lower,getting down to 8 ft or so,was so calm they didnt start right away,that was cool,didnt have to work the sticks so much at first. The only thing I wish I didnt have to do is hit the spoileron switch when it goes vertical to hover from harrier,I like to shut it off in case it falls out,those spoilerons can impede the pullout if you are in a bad way. I guess when I get it down good enough,I wont ever get in a bad position.
