RE: Hobbico Superstar EP
I have a Superstar with Ailerons I use for a video camera plane. I use an AXI 2808-20 with a wood 10X6 prop and it will go vertical as long as I want. I use the wood prop because it looks cool and performs as well as an APC. The plane weighs 2 lbs 6 ounces with a 2100 mAh ThunderPower 3 cell Li Poly. I replaced the gear with an aluminum one I fabricated from 6061-T6 aluminum which I bought from scrap for a couple of dollars from a metal supplier but you can buy the same thing from model suppliers. I moved the main servos (Hitec 425 BB) forward under the CG and put the Thunder Power battery over the landing gear. That way I can shift the battery around for correct C/G depending on the confirguration I am using with the camera.
The landing gear just bolts on with two 6-32 bolts. I cut a piece of white vinyl 3" by 1" to put it crosswise between the fuselage and the aluminum gear to protect the fuse from the aluminum gear shock. Many flights and the fuselage is perfect and no landing gear problems. It is beautiful.
I also use "Tundra Tires" which are inflatable tires from Trexler (330) 296-9677. They are their # 6 heavy wall tires and really cushion the landing and stop bouncing and facilitate takeoffs in rough fields due to their width. They are fun to inflate, and can be patched with a bicycle patch kit if you damage one on a sharp object.
I use two HS-81 servos for the ailerons, each mounted in 1/2 of the wing which I made to come apart for transport. I made the wing bolt-on.
I'm using a videocam from Black Widow and downlink to a Sony Digital Video Recorder, although you can use a video cam as easily.
I added a steerable tailwheel driven from a second pushrod running thorugh a tube and attached to the rudder servo.
The power of the outrunner is not required all the time, but in a pinch I can push the throttle up and get out of a tight spot with the camera onboard.
I use a Jeti speed control.
Finally I latch the bottom hatch with a 1/2" wide by 1-1/4" long white vinyl tab cut out of 1/16" vinyl sheet from the hobby shop. It is attached to the middle of the hatch at the front with a 2-56 bolt permanently and to the landing gear with a 4-40 nylon bolt which runs into a tapped hole in the middle of the landing gear. Loosen this bolt to take the hatch off.
I want it easy to remove but very secure. I did an 1/2 loop pullout from inverted and it threw the 2100 mAh Li Poly out through the hatch opening as I pulled level and I never found the battery. I had the hatch held on with a rubber band temporarily while I was experimenting. Learned from that. Now I velcro the battery in place with a 1" X 1-1/2" piece of velcro, and put a strap around it too and bolt the hatch closed. Too expensive and dangerous firing Li-Poly missiles out of a plane over the freeway which is what happened. The plane fluttered down and landed on a strip of grass unharmed.
