And who has that much time
And how do you keep your feet on the ground

Rally Sport (2B variant)

Post  fredvon4 on Wed Oct 21, 2015 6:57 am

OK I am editing this in as I just hit the facebook link (I never go to FB links)

So below is just information from my past and nothing to do with the QuickSilver than to note my Rotec was sort of copy of the quick Silver

Original post:
Looks a lot like a Rotec Rally

At Fort Hood around late 1982 I help a helicopter pilot start and run a Ultra Lite run way and sales demonstration side line business.  We were both mid career active duty soldiers.  We both got taught to safely fly the Rotec Rally series of ultra lites in Waco Texas.  Ultimately I became one of the first customers just as the Sport model arrived early 1983. The sport was basically a Rally 2B with strengthened materials allowing modest aerobatics because the wing could take negative loading. We also (illegally) hopped up the Cuyuna 430 two stroke for a bit more power.

If you just bought it or are still thinking about it...the air-frame is pretty sound and you should concentrate mostly on the connection points for dissimilar metal corrosion where stainless bolts got through the aluminum parts.

 The engine is what it is and I am sure is re-build-able if high hours.

The sail materiel, Dacron, is the biggest problem because you can NOT see the age related fatigue and all the stitched seams are suspect.  Re covering with new is still possible but will be fairly expensive

If it is an older model a lot of the control surfaces were actuated by rope attached to Plastic fittings and all the plastic parts will have UV degradation and be suspect

The 18 months I owned it, I had a blast with my Three dimensional motorcycle teaching myself a few aerobatic maneuvers like rolling it over and letting it fall through an inside loop for a reversal of direction. It never did have enough power to do a full inside loop. A dive to increase airspeed to start a loop bothered me as there is a definite limit on the G stresses the air-frame can handle

I stored mine while on a three year trip to Germany. When I got back the cloth was not airworthy so I sold the plane and moved on with life

Nice, that looks like an quicksilver MX. What engine is in it Rotax 503?

I have a trike "Air Creation GTE" which is powered by a 582 with Arplast prop.
Here's a pic of myself in it after a very long flight from 19A (Jackson Co Airport) to 5A2 (Warner Robins Airpark) 174 total statue miles Flying   (Bandit)

Heres another pic this time of me flying, this flight was the first flight of a new rebuilt engine an this pic shows me doing a low flyby or just coming into one.
