Mod-U-Liptical Boost
(Contributed - by Mark Daughtry Sr.)

[Rocket Pic]

This model features an interchangeable motor can that has four configurations hence the "Mod" part of the name:

1. 13mm (Estes mini or "T" engines) times 2

2. 13mm times 3

3. 18mm times 1

4. 24mm times 1

The glider features all swept elliptical surfaces hence the "liptical" part of the name.

The pod breaks in the middle and is recovered with a

1 1/2" X 6' streamer.

Mod-U-Liptical Flight History Report:

[Rocket Pic 02/24/98 Launched on 2 ea. A3-4T's. Good flight, ejection/separation, a touch of stalling during glide. Added weight to nose before next launch.

04/11/98Launched on 2 ea A10-3T's. Good flight, ejection/separation, and glide.

04/11/98 Launched on 3 ea A10-3T's. One engine did not light, but though it had uneven thrust, it still logged a good flight with a little bit of an arc to it.

04/11/98 Launched on a C6-5. Quick, high boost with *very* long glide time. (did not have a stopwatch though)

04/11/98 Launched on a D12-5. I thought the C flight was fast, but boy howdy, this one really rocked! Very quick, high flight and the glider seemed to hang in the air forever. It took me about 45 minutes to find the model. Thank goodness for fluorescent orange paint!

04/18/98 Launched on 2 ea A10-3T's. Good boost, but the Kevlar® shock line got tangled up in the fuselage behind the wing for a Red Barron. No damage to the model.

04/18/98 Launched on 3 ea A10-3T's. Good straight boost, flawless ejection/separation, and good glide.

05/02/98 Launched on 2 ea A10-3T's. Good boost, perfect ejection/separation, and good glide.

05/09/98 Launched on a C6-5. Good boost, but then strange things happened. It first appeared that the shock line had become entangled in the fuselage, but then the pieces untangled and the glider came in at an extreme (about 45 degree) angle. It buried the nose end of the glider into the soft dirt about 1/2". Upon inspection of the glider, there was a piece of recovery wadding (Estes type) clinging to one of the wings near the fuselage.

05/17/98 Launched on on 2 ea A10-3T's. Flawless flight from boost to glide.

GUEST's OPINION:
08/10 - "I built and flew this kit and found it challenging, but it's a wonderful flier. The hardest part was getting it to and from the site without damaging it! The suggestion of bright colors (e.g., fluorescent red-orange) is a darn good one. I suggest the entire glider be painted this color and don't forget your return address. My ultimate goal is to fly this thing at Black Rock with an F12!" (R.B.O.)

Date	Name	Motor	Ejection/ Altitude	Wind	Notes
08-07-2010	Ross Ohmen	Est SU C6-3	Apogee - Perfect	Calm	Event: Aeronaut - On my first flight, the pop-pod tangled with the glider, and everything fluttered to the ground - no damage.
08-07-2010	Ross Ohmen	Est SU C6-3	Apogee - Perfect	Calm	Event: Aeronaut - On the second flight, I rolled up the streamer in the shock cord, and it did not tangle with the glider. Glider was slightly tail-heavy, which caused a pronounced stall pattern.
08-07-2010	Ross Ohmen	Est SU C6-3	Apogee - Perfect	Calm	Event: Aeronaut - Added more nose weight, and this time it was perfect. Didn't go too high, but sure flew a long time!!! Wide circles with very low descent rate - glided right off the flight line, and into the desert. Awesome, and the crowd loved it.
