So in December 2013 I thought I want something bigger so I decided to upsize my favourite airplane - the MB339

This is what I was aiming for :

I didn't have any detailed plans, only a low quality jpeg image of the side and top view, the easiest way for me to scale it up was to use an old piece of cardboard and an overhead projector. I projected the image onto the cardboard and traced it by hand.

Below are some Pics I took along the way....Continue Reading

So after lots of scheming i finally did it, I would call this my prototype but it works pretty well, so it might be a while before I build the final one.

Ill add more detail on the hardware later.

New life for an old friend. I bought this old EPP Aermacchi 339 from Canterbury Sailplanes about 10 years ago. When the patching started to get more than the original covering I decided to strip her and completely re-cover. Cant wait to her back on the slope.

So after three crashes, various repairs, and trying to figure out why I kept on getting brown outs, it turned out not to be brown outs after all, I had servo stalls on the eleron servo's. I replaced them with two decent 3kg/cd servos and now she flies like a dream.

Here is the video of my first successful flight, i strapped the camera to the back of my car just to have some proof of the flight.

I thought I would rather add my pictures, videos and comments regarding my U2 build here.

So I had this idea that I want to build an U2 type spyplane, so without delay I drove to the first place i found in Cape Town that sells EPP and bought the only piece off foam they had left, it was about 1200 x 800 x 250.

And so it start . . .

I couldn't find any proper detailed drawing for the U2 online, so I settled for the drawing of a NASA ER2 as a base and added my own twist. Wings are slightly longer and I widened the wing tips considerably, fuzz was mostly fashioned as i went along, Elevator and Rudder are also a thumb suck and I suspect I might have to change them later on. Added ailerons and flaps, but will also need to do some more with them.

. . . covering all done, I added a 300g piece of led and a nice big battery with BEC to allow for other goodies I want to add later, the total weight is about 600g I had to add to the nose to get the CG right.
Only thing that remains is to make a bottom payload cover, mount the control horns, connect the servo's, add radio . . . and fly .
I am a bit concerned that my horizontal stab might not big enough, but I'm planning to redo the tail section later. Ive also noticed after all the tape and covering the travel on the flaps and ailerons is a bit restricted . . . so if i'm right ill have to cut them off, do a bit of sanding and reattach. But im hoping ill be able to do a successful (ie not crash on fist launch ) maiden...Continue Reading
