WM Midget Mustang. What engine?
I have alot of "poop" for you so take a seat.
I have the white version for 3 years. Flown it only a handful of times. Not because it is a bad plane but white turned out to be the worse color to fly. I have several hotrods. I mounted a OS 1.08 sideways with a Pitts underneath. The original first choice was the 91FX but could had problems.
* First off I glassed the whole firewall area. You cant see it anyways with the cowl and it adds extra strength.
* Take a good look at your servo tray. Two of the slots in the back of it-One for the rudder and one for the elevator. I changed it. I cut out the wood between the two to make one big slot to hold 3 servos. The middle would be for the rudder and the outside for each elevator. I ran two elevator servos.
* I also change the landing gear (recently) I removed the struts for the wings and bought the regular aluminum type you see on trainers. Painted it white, put on the wheel pants and Kavan wheels and the entire appearence of this plane changed for the better.
* I mounted this aluminum piece to the front of the wing. I glassed it up and made a hard point for the gear to go in. I also use Nylon 1/4x20 .
The plane is sweet but a handful. I find landings should have a shallow approach or it won't slow down. I also set up the flaperon function. It is a good plane
* I can't post it here because it has to many pixels but you have to see this before you start and I promise you that you'll go for it. Send me your email address and I'll get it to you.
