Thanks Don i will give some a try. joe

Don,
Looks like our MI LHS (the Prop Shop) carries "Foam Cure". I know you are down in Florida but you will return some time. Same price as your link on line.

Thanks for that. Support of the local shops is a good thing.

My ov-10 is coming along nicely thanks to MPF.
I am really enjoying working with this stuff. It is far nicer to work with compared to depron.
The only complaint I have is that some sheets are a bit wavey, some have as much as 1mm difference in thickness.

I still haven't decided what to do with the elevator control. So far I have a servo in one of the booms and intend to fit a bell crank at the tail.
Open to other suggestions.

Fit the elevator servo in the other boom and use a flexible sleeved control rod. This way you'll balance the servos weight laterally, and not start off with a plane that wants to roll because one side is too heavy.

Edit: I think I misunderstood. I thought your servo in the boom with a bell crank at the tail was for rudder control. Anyhow now you can have both!

Wow, Brett, you ain't just foolin' around! That bird is looking great! Shows off the formability of MPF, too.

On the thickness & waves, yes, unfortunately MPF isn't as consistent as Depron (not as expensive as that either, of course; and like or not, we're process constrained on those characteristics - getting the best the process can deliver at this time) For most folks the variations are inconsequential or minor irritations. We don't recommend using MPF for applications like the 3D profiles where the straightness & stiffness of Depron is critical. I've never used Depron, having come at the hobby from fanfold and dollar store foams, and MPF is orders of magnitude better that those. But I can understand that folk coming from Depron may see it differently. My experience has been that they seldom can be detected in the finished plane.

Thanks, I may go for the flexible idea because it would be a lot neater.

I was going to just fit a counterweight in the wing to offset the servo. I always balance my planes laterally.
However I may fit a rudder servo on the other side. I wasn't going to use rudders but am rethinking that.

Re: the waviness, you just have to watch what side you are using because one side is nice and flat.

Have you guys considered adding magnets to you site ? I would think they could be slid into the box and its something that i use on almost all my builds .

Magnets....Interesting suggestion.

Any others think they would like to be able to order magnets with foam?

And, what specifications of magnets would be desired?

I would highly consider it. 1/4" round neodymium are the ones I look for most often. Good for cowls, hatches, canopies...

Brett, which glue are you using on the mpf, and is it sandable?

Speaking of magnets, here's a tip I find invaluable. I always have the hardest time getting screws into servo horns and micro connectors etc etc etc without dropping and losing them. So, here's what I do: I have a stack of 1/8" neodymium magnets I got from a jeweler friend. He was using them as clasps for bracelets and necklaces. Stick one on the side of your screwdriver to instantly magnetize it and never drop a screw again. Thought I'd share since I did this trick just tonight.

I have 1 of these

That way you can magnetize and demagnetize as needed
