Ok. Thanks for being honest. I have seen my share of high speed claims that were bogus too. It's fun to point a radar gun at them and show them how wrong they are sometimes
I was just trying to get a feel for how well they designed the plane. I remember the smaller plane had an incidence problem too, which is a little unusual these days and can be a pain if the tail is glued on!
I used to race giant scale and my plane did 180mph. After watching a race with Lancairs doing 230, I had my race and I thought there was something wrong with my plane. It looked so slow! A friend assured me that it was running fine and my internal speedo just got all messed up watching crazy fast smaller airplanes rip around the course.
....so don't watch a brushless powered speed 400 plane fly before you fly yours!
