She looks like a winner!

I have always wondered how the metal pan gets grafted into the fiberglass fuselage.

Here a few little videos from the first test flights 2011 with the MB 40 and BVM ´91 speeder.
It is very difficult for the cameraman to find the fast modell in the blue sky. I think better than nothing to get a little feeling for the speed.

You seem to have about 2:45 of fuel on board - I would guess for the .91 that is about 400cc or a little more?

What is rpm on the ground?

The 6,5ccm MB pylon engine runs on 31 500 rpm/min on the ground the BVM ´91 with 23 500 rmp/min.

400ccm fuel for the 15ccm engine and 240 ccm for the 6,5ccm engine.

Best regards Michael
