I completed the MTP II (Modular Testing Platform) as far as I could while I waited to receive the new Motor and Servos I’d ordered. They came in the last day of this week, so I’ll be completing the MTP II next week.

There is a lot of improvements on this design/construction over the first MTP, some include:

-Minor fuselage improvements for better aerodynamics and strength. (including moving the wooden dowels to be apart of the construction instead of just sitting inside the fuselage.
-Improved airfoil: I got a lot of feedback that while the K2 airfoil was functional, I’d be better off with a more classic airfoil, so I built a Clark Y airfoil. I got the information for this wing from: http://www.worldofkrauss.com/foils which is an AMAZING site for airfoil research. You HAVE to go check it out. I gives not only the exact shape of each airfoil, but also it’s flight characteristics. Very cool.
-Next, instead of using one of my radio’s channel to control the rudder, I’m using it to control a set of ailerons, which will give me a lot more control and allow me additional roll stability options. I stole this idea from fellow YouTube user PeteDaws.
-I also used CA Foam Safe Glue instead of Hot Glue. In the past I’d had airplane literally melt in the trunk of my car due to all the heat, CA Glue won’t fail due to that as once it’s bonded, it doesn’t let go. Also I found that the construction of the airplane was much more precise and clean. Weight also dropped by about 15 – 20%.
-Lastly, I ordered a larger motor as the last motor was too weak for this size of airplane.
