I set out to find the max speed of my MTP2, with disastrous consequences.
I used the “How Fast” (see http://www.wingedshadow.com/howfast.html) to tell me my max airspeed after each flight.
At full throttle flying straight, I got 62 MPH, in a steep dive it reached 79 MPH, and in a straight down deadly dive, it reached 92, after which the wing separated and the airplane was destroyed!
The MTP3 will be built over the next few weeks and will have new design features to protect against this happening again as well as other improvements.
