Michael Moore's Skyflex 2000
From: Michael Moore grizzman(at)concentric.net
I have some pictures of my maiden electric um-er-flying machine -
Since I haven't been flying in 10 or so years I wanted to start out with something hopefully slow and easy to fly, quick to get together, and fun. I happened across the SKYFLEX 2000 that I bought from New Creations. Mr. Massey also made me up a 7 cell 1700 SCRC pack to go with it.
I have to say that this is a good choice for beginners. I opted to try it without a trainer or instruction because I'm stupid and impatient - but lucky! The first flight was great. With the motor turned on (it has ON and OFF) the thing climbs out at about a 30+ degree angle and is nice and forgiving when I throw too much control into it.
It climbed very fast (in my eyes anyway) and I circled it a few times then brought it in. Without power it descends at about a 30 or so degree angle. The first landing was right down the runway; untill it tipped over at the very end, but I don't count that.
The second flight was fantastic. I became a tad more courageous and flew out farther and did some circles and figure eights untill amidst a steep turn a rubber band broke (my excuse anyway) that holds the sail to one of the frame spars and the thing went into a spin from about 250 feet up straight down into a tree!!! The End I Thought! Funny thing was that it sustained not a bit of damage. The battery shot out along with the canopy cover and that was it. No scrapes, scratches, bent sail tubes, sail holes, nothing. So, I recharged and went back up. I'm not sure how long it will run per flight as my nerves could not allow me to test this machines limits just yet and I was happy just to get it back with juice to spare.
I flew two more good flights and had another minor crash before calling it a day. In the photos you can see the only damage it sustained, a bit of green smudge on the nose from grass smearing on it as a result of the second crash. Other than that - long lives the SKYFLEX. It was great fun to fly and built like a rock, but lighter, and I wish to enter it as a possible beginer flying machine. I haven't flown any others to compare - but it sure was great fun.
I did have problems, especially near the end, with severe steering servo glitching. So, after I took the victory pictures, I dismantled the thing to put on some motor capacitors which I hope do the trick (I paid attention to the EZone Digest). I may also possibly put a small speed controller in as well since it actually has too much power for me when turned on full blast.
Mirage 550 probably the next project -
As always,
thanks for EZone!Mike from Louisburg, N.C.
Robert Wagoner's A-10
Robert is flying his impressive Combat Models A-10 on two Wemotec Ecofan PRO ducted fans powered by Ultra 930/10 motors in parallel connection. Robert says he is still experimenting with cell counts, but is currently using a 20 cell pack of 2000 RC cells to power his impressive warbird.
The wing span of the model is 52 inches. The models length is 47 inches. The all up weight of the aircraft is 7.5 lbs, which brings the wing loading up to a hefty 40 oz/sq. ft. on the 423 sq. inch wing. Full throttle current draw is 38.5 amps, which gives about 773 watts for a power loading of roughly 100 watts/pound.
Robert is using Robart pneumatic retract units. The model also sports working rudder, aileron, elevator, and flap controls. A Hitec Prism 7x radio is used for control.

Gordon Bradt's Lazy Bee
This is probably one of the prettiest pictures we've shown in the gallery. Gordon tells us his Bee is being piloted by Snoopy, who sits in an open cockpit behind the wing. Snoopy's head is spring mounted and moves in concert with the tail feathers. The wing span is modified to a compromise 44 inches. Power is by a geared Astro 05 cobalt motor secured by cable ties, and is fueled by seven Sanyo 1500 mah cells. The wheels are scratch built using mono filament line for spokes and latex rubber tubing for tires. The "training wheel" landing gear is V shaped to provide stability and ground clearance for the Master Airscrew 11x7 wooden prop.
