We’ve been discussing this on the “What’s on your building board forum” under “Satellite 788” but I thought I should put it here because it seems like I was not the only one under the impression that you could use any non-schneurle 15-19 for the 2017 One Design Event at the Nats. But I just re-read the rules and found you are supposed to use a nostalgia legal engine, as follows:
2017: Zingo (AMA or FAI) / Witchhawk 500 (AMA),with any class ‘A’ NFFS Nostalgia legal engine may be used for the Witchhawk and Zingo One-Design models.
Originally I was going to build a Zingo with a Supertigre .15 and then I thought, why don’t I just use my old Witchawk that I built back in the day with a Veco 19BB engine? I am going to have to think of something else, probably an OS .19

The original rules was written so that only “Non-schneurle .15” were eligible. Apparently some felt that the Witch hawk 500 would be un competitive with a .15 up front, so the rulemakers eventually changed it, so that a “Class A Nostalgia” engine can be used. Most build either design to approx 19-21ozs. and will use a .19, either a Veco .19 Series 100 or O.S. Max .19 for grunt. A Nos .19 turning a 8×4 prop, 18-19K will have more oomph that a Nos .15 turning 7×4, 18.5-20K. This change to NOS engines does even the playing field between the two designs. I had originally planned to build a ,hopefully, lightweight Zingo with a very good S.T. G-15…still thinking of a Zingo but now with a tweaked Veco 19 Series 100 burning 40% fuel.

Robert and Simon…Both right…Need to use a Nostalgia legal engine. Not sure what I was thinking??Daa!! I’m not sure I can carve enough weight out of my FAI Zingo…Might have to start over.

Yeah, I think I’m going to have to start again too…11/29/2016 at 10:26 am #78419Rudy KluiberParticipant
Just remember, guys….He who hesitates (er,,, procrastinates),
Only builds one Zingo.

Alright Rudy, which one are you going to build?…You probably have one of each.!

Denny, gonna be the Zingo with a tweaked Veco 19. I discovered that
sometime in the far distant past I had cut out a set of wing and stab
ribs for a Zingo and still had the plans. So, an easy choice. Also,
while I am sure that the WH 500 is a good design, I was never too partial
to designs with a forward rudder. BTW, a little bit of of trivia…..I
Seem to recall that Jim Clem’s AMA number was the nest number after mine.

Well, I just happen to have a set of Zingo ribs too that Brian Malin at BMJR was kind enough to send me. However, I’m torn. I have a Witchawk that I built a long time ago with a Veco BB .19 and I just need to build a new wing for it and change to a different engine. Well, I should build a new fuselage too as I broke it in half and repaired it with fiberglass a long time ago, and it has a hard tank. So, basically I have a stab and that’s been repaired too. Jim Clem is one of my favorite designers. And I have a feeling everyone is going to build a Zingo, so I’m leaning towards the Witchawk.
