One if Ed Fishers designs that is overlooked is the Zippy Sport. No quicker way to build a wing...

Often a two stroke on the front but this one is a 1834 VW.


Based on the takeoff run it may be a little heavy for the plane. I wonder how it would perform with one of Scott Caslers 45hp 86x94mm twins at 85lbs.

I built and then flew a Zippy Sport for many years.
My plane started out with a Rotax 503.....it performed very well.
A year later, I had the opportunity to pick up and install a Rotax 582....it flew like a homesick angel.
Then I built a 2180 Revmaster for another project I was working on but didn't want to do the break in & testing on the new airframe,so,a new engine mount later and a recalculated weight & balance and the new engine was installed......even with the added weight the plane flew awesome.

From what I saw on the video......there is nothing wrong with the airframe & engine combination.
That extended take off run was due to the pilot dragging the tail down the runway.
The tail should have been up within 15 - 20 feet of him applying power.
That was pilot error....not the aircraft.

What a great post. How do you think it would fair with a 1834cc vw and a 225lb capitan?

That will depend on many factors......your piloting skills,all up weight of you & aircraft,density altitude,how well your engine is running,prop & pitch......etc.
My aircraft exceeded the published factory figures and I was very happy with it.
But.....my aircraft was also very overpowered with the Rotax 582 because I installed a PEP kit that gave it another 10 - 15hp.
So my 582 was putting out around 75-80 hp. along with an adjustable pitch 3 blade Ivoprop.
And then I was partaking in a no-no with the Revmaster 2180.....I was running a 3 blade Ivoprop on it so I could play with the pitch as needed/wanted.
A composite prop on a direct drive 4 stroke is generally frowned upon but I kept an eye on the blade tapes and never had an issue....I was lucky.

There's just too many factors to consider to give you hard numbers.
Build the plane light and learn how to fly it properly and you will acheive or surpass the factory numbers...it's a great design and good flying airframe.

One word of advice/caution.....be careful pushing the nose over under power...it will see VNE very quickly.

Yes the builder of my Cygnet Zig Berzins was among the first to have a composite prop issue on a direct drive VW and expended a great effort spreading the word to prevent the grief he experienced happening to other aviators. I have a huge book of correspondence between him the EAA and IvoProp. A very interesting read. The benafit of his efforts was you were aware of the risk you were taking short term and mitigation was in place the whole time I am sure.

Ed gave me Zipster plan set #2 he was/is a prolific designer who has contributed to experimental aviation a great deal of innovation.

I am grateful for the 100+ hours of conversations I have had with Ed over 20 years.

I know he has passed his designs on to new owners to take forward. I wish more.of his design cohorts did this several interesting designs are permanently out of circulation.

I sold my plane about 14-15 years ago to a local guy and thought it would be around for a while.
2 months after selling it the guy moved to Florida and I havent seen the plane since.
Hindsight being what it is.....I sometimes wish I had kept it.

Regrets... how was the build I suspect the Widget System makes for a very quick build on the wing. I know who owns then widget tooling and rights. The unknown is who is selling the ZippySport plans? I think it is a Stitts Skycoupe inspired single seat. I will give Ed a call unless he chimes in here.

How was the view I am spoiled in the Cygnet SF2A.

That's Jerry......he's a great guy to deal with.

Found some interesting history at lunch Zippy started with a 1200CC VW engine and migrated away as it transitioned into GreenSky's hands. Also this design appears to have escaped the Widget/Tube method Ed Developed. I did not know it had folding wings... If anyone has pictures of the wings folded please upload on this dialog...

I am attaching a snip from the Sonerai list Ed visits. He used a flywheel drive 12-1300cc vw for about 4 years on a zippy Sport. Seems like a flywheel drive 1600-2180 would make a fine Zippy Sport Prime Mover. I believe this factoid has gotten POP's attention in the past. SSSC or Zippy Sport hmmm.

It would fly much better with a standard weight pilot.
230# pilots should be looking at bigger aircraft, IMHO.
Yes I would lean to a 2110 or 82x90.5VW I will probably stick with the Cygnet for the time being with a great big wing it flies at gross perfectly fine. The orange one was flown by a 160lb pilot on a 1600cc. Ed was closer to 160 in those days he flew a 1200cc.

POPS SSSC may be more fun if speed is not the game and already proven for 230lb pilots on a 1834VW
