To be honest I am a little concerned with the structural integrity of the whole Airplane...

But looking at this photo...



The engine looks skewed to the right... (Which has obviously been done to clear the exhaust mount)

The Fuse looks to be either leaning to the right, or bent... (This could be from the Camera or Landing gear)

I noticed you had not drawn the Horizontal Thrust lines onto the fire wall and I think your engine is too high as a result...

Apart from the Aero issue associated with this, I think your Carb may be too high in comparison to the fuel tank, which may mean engine/fuel problems...

I am comparing your Airplane to my 60 setting on the work bench right now...

I had to take out about 3/4 of an inch on both sides of the cheeks to clear a ST G-90 into the Airplane... My Carb is sunk below the Cheeks!!!

And although Quirky... I don't think you are onto a winner with the Lego men... At least weight wise… If not because the first hard landing is probably going to send them west…

Not trying to be a downer Dude... But there would be nothing worse than paying for and building the Airplane only to wreck it in the first minute of the first flight...
