This is a plane I built when I got my first RFFS-100 system. Wing span is 19-inches, area is 123 sq. in., and AUW is 23.4g, for a wing loading of about 0.97 oz.sq.ft. Wing is 1mm CF rod. Fuselage is 2.3mm CF tube. Tail is 5-lb density balsa, 1/32 for rudder and 1/16 for the elevator. Covering is RA Microlite, using Avery purple glue stick on the wing. The plane is essentially a scaled down Kolibri/Stubenfliege, with a conventional tail and actuators instead of servos. Since Kolibri is German for Hummingbird. My friend Klaus Helped me name this one Stechmücke, which means little stinging bug, or mosquito.

It flew the first time in March 2001, originally with 120x3 NiMH cells, but now with a Kokam 145mAh LiPoly cell. I'm currently using a M20-HV motor geared 6:1 with a Wes 160x120mm (6x5.0) CF prop. The plan has been published in the August 2001 issue of RC Microflight.

Todd Woodhouse has built a version from the RC Microflight plan. He used the Selman actuators, which weigh about 1g each more than the in-tail actuatorss, but can be mounted near the CG. He saved weight elsewhere with a shorter fuselage in front of the wing, since balancing is now easier to achieve. He also used a built-up tail. His AUW ended up being 22.8g. Nice job building light.

He writes: "First couple flights tonight, and they went great! Plenty of power to go from floor to ceiling and adequate rudder authority to do figure eights inside about a 25 foot square. I would fly under a volleyball net, then a climbing 180 degree turn back up and over the top of the net."
