Bass, and spruce, for that matter, is pretty soft.  Shouldn't the engine bearers be maple?

Hi Rich,

Sorry, but Bass is not a suitable material for engine mounts, in my opinion.
You need something much harder and stiffer - good hard Maple or (as Bill says) Beech if you can get it.
Metal is the best, however.

You guys are probably right. If I ever find a suitable diesel, I'll cut off the existing mounts and use metal. Otherwise, I'll convert it to electric.

If you've been wondering...

The number 18 is pretty much done. I have done a couple of short test glides, and it does float. I did find out that because of where I put the electronic timer and the servo, there is a weak area just aft of the wing pylon. In the pictures you can plainly see that I've reinforced the area with CF cloth. The weather has turned cold  here, so I've not been able to paint that area yet (no place inside to spray-paint.

I don't expect to do any more flight testing until March or April.

The airplane did come out light, so I'm hoping for some nice flying.
