I was given this Pitts by a friend who built it 25 years ago. It was powered with a 15 size glow engine. It was only flown once because of how under powered it was. It was built off of Marutaka plans (and it took me a lot of research to figure that out) and possibly a kit, I don't really know but there isn't any stamping on the parts that suggests it was a kit.
When I got it it was very heavy and with a wingspan of only 31 inches so it had extremely high wing loading. I made an effort to make the airplane as light and powerful as possible but on a budget. I stripped the airplane of all of it's electronics and replaced them all. The servos are parkzone metal gears with the exception of the aileron servo which is an old standard size servo I had laying around. The reason that I used a full sized servo for the ailerons is because the hole was cut out that big and I didn't want to do a bunch of wood work to make it smaller. I powered it with a Detrum 3720 650Kv brushless outrunner with a 13X6 prop. The ESC was a Detrum 50A and the battery was a 1300mAh 3S.
The airplane flew fairly well with this setup but it was still a little less power than I wanted. However the wing loading had gotten low enough that it didn't have to make a smoking hot landing. So I replaced the motor with a Turnigy 3542/4 1450Kv outrunner using the same 13X6 prop 1300mAh 3s and a Castle 60A ESC. Just recently I bought some 1000mAh 4S batteries that are roughly the same size and weight as the...Continue Reading

I built this Gee Bee Model D last night. I have just a little more work to do to the bottom of the nose but otherwise it is done. It has a wingspan of just over thirty inches and it is about 30 inches long. It has a Turnigy XP 3530/14 motor, 10X6 prop, with a Turnigy 30A ESC and a 1000mah 4S battery. I was going to test fly it tonight but it is going to have to wait for a couple of months because it turns out that my transmitter is broken and as I am in high school and I don't have a job I can't afford a new transmitter.

I spent two nights building this airplane it is the version three of my sixty inch twin boom. I have also done three thirty inch versions. It has a mixture of a Armin wing and a FliteTest wing. It is designed to carry a GoPro and still have extreme performance.

I have built a flitetest simple storch and a Foamcub swappable now the fun/foamcub has been flow several times now but the storch remains electronic-less. I don't have pictures of the funcub but it looks astoundingly like a funcub.

I am just finishing up my Bücker Student Swappable model designed by nernic. I am hoping to have a maiden done by Friday or Saturday.

Today is a sad, sad day as today I lost my beloved friend, Hyperion Yak 55SP. After a 35 turn tumble the right wing folded over and no matter how hard I tried it just didn't have enough aileron to hold a knife edge. When I arrived at the scene it was a grisly sight, there was blood (plywood and balsa) everywhere, the heart was still beating (ESC and it was actually beeping not beating) and the head (motor, firewall and cowling) was severed completely. As you can see in the picture I was devastated.

I couldn't help but pust this picture of my families Piper Clipper. It is my favorite picture of it and I was looking at it and I decided to post it. The picture was taken by Roger Cain
