Stuart.

Yes, they are epoxy and warming will allow some forming. I guess submerging would be the way, start with a slightly cooler temp and increasing. 75-80 degree water to start?

Thanks!

I gave this a try. (Very) hot water did help them soften, but by the time I'd moved a louvre from the hot water to the fuselage and started screwing it down, it had cooled off enough that it was back to its original shape!

So, I just used a lot of screws, which di the job!

Stuart has finished the beast, makes the 32" prop look quite small!!
A tinted canopy is planned...

Once the LMA paperwork is back he can test fly and enjoy all the work.

So I finally got around to running the engine this morning. The MVVS took a few flips to get going where the carb diaphragms were dry, but one it fired up it ran like a Swiss watch. Very, very smooth.

Next step is the maiden. Hopefully in the next couple of weeks.....
