Hey all been lurking for a while now am really considering a build. I have 2 O.S. MAX 15 FP (rn) motors - glow and would like to see if the twin can be built big enough for these to work. I have a new flat of blue FF and some $tree foam board and a lot of time coming up during the winter months ahead. Hobby Lobby is only 20 miles north and they have balsa! Any one done this before or could offer advice would be appreciated.

IDEA: Could you do something like a SPAD-variation and use those glow engines? That would get you some increased weight and a possible airframe that wouldn't shake apart with glow motors like the foamies.
Just a thought, not my area of expertise; perhaps someone has considered this. Target the size based on an anticipated weight to match what you can pull with these.
Anyone have ideas on that?

I remember a article a long time ago with that head line....
It means; Build it like the dad gum plans!

Going Nitro and or Spad would be a whole different animal from Foam and tapes original idea here.

I wouldn't give a dollar for any o.s. FP engine ever made. But that's just me.
I do however have two O.S. .10 FSR's n.i.b.

So post up a link if anyone gets a Nitro version going.....

I have been looking at twins for a while now and do have a local sign shop here in town that makes signs and have talked to him about getting larger scrap pieces for single wing construction and have no problem with that!
I am not sure on the size of the project as I really have not built much more than nothing but now that I have the motors might be a hoot to try. Any suggestions welcome!

Front landing gear installed and servo attached.
Larry, you might want to put a big Z-bend in that push-rod, to give it a bit of spring.

Otherwise everytime one of those wheels hits a small stone, it'll put a lot of force on the servo gears and could strip them.

There are various other ways of protecting the servo against shock loads, but that's the simplest.

I see no reason why a coroplast version could not be built with glo engines as the power plant should fly well.... might want to add flaps.

Good luck Larry. You'll need to get information on how much lift you can get with the wing and motor information to see just how large you can make this bird. It may end up being very heavy, being a flying boxcar; it has a lot of surface area on the fuselage That may drive your size down some. Don't know if you can get some advice from the SPAD thread, but might be worth checking in with those guys or another similar thread.

I just cut out the foam for a 75%'er. I take these taped together tiled plans to Office Max and have them laminated then cut out the pieces. This makes a rigid pattern that can be used over and over. A big thanks to the very ingenious F&T brothers and Mr. Larry for the first rate plans.

I have been following the RCPowers site and he has been working on a VTOL craft for quite some time. I was very surprised to see the video from F&T with their VTOL that seems to work very well. Congrats to the guys at F&T. This is a photo my F150 Hydro built from Depron using RCPowers plans. I must say Mr. Larry's plans are nicer. My next Depron plane is the 75% Cargo twin.

The funky whirring, squeeking, whirring, squeeking noises the motors make only add to the coolness of the video.
