A concern that might develop in the "stock" class is availability of original VW parts. Though intended to be budget-minded in the original rules, nowadays a 1500 or 1600 with original parts all in great spec could get pricey. Of course no mfg aero engine has those internals but they dont offer 1600s either. An example of an enigma is that many say rebuilt stock rods are often inferior to affordable I beam or H beam rods. No real advantage gained other than peace of mind at 4K RPMs. I assume pistons arent considered internal. All to be ironed out I'm sure Just thinkin' Dave

The FV 1600 rules stated 'free of restriction' with the rods, and any piston, ring set was legal…I will dive into the specs I just found this week, and be more precise here soon. When Jack gets the rules re-typed, I will be sending out rules packages to race number holders….

More food for thought:
You mentioned a restriction on opening the cases for larger cylinders. I have an engine that has been opened for 92mm cylinders. The stroke is stoke so the displacement is 1835. If I wanted to drop back down to 1600cc (1585, actually), I could sleeve the cases and put 85.5mm (stock) cylinders back in the holes. However, if we have a restriction against opening the cases (something you mentioned earlier in this thread), then I could rightfully be challenged and disqualified. I would suggest we avoid that language so that cases such as mine can still be used in the FV class.

Yes, great idea, and its all in how we word things….I am very open to suggestions and constructive criticism. What I DO NOT want is for Supervee to become a rich man's venue…I don't want this to cost what International Formula one now costs!! Thanks for the chart, I have been looking for that for some time. When Jack gets the rules retyped, I am going to have them printed and sent out to race number holders who are serious about competing, and hope to get feedback….

Chucker, I know one uses spacers to set deck height but I would think you'd have to machine some "top hat" style bushings that act as spacers and wall shims that drop into the case. An issue there might be the different coefficients of expansion of differing metals. Otherwise use super thick-walled cylinders with the smaller bore(do they make those?). Maybe I just haven't looked into the options but curious what you have in mind. Dave

Hoping to have a much updated rules package typed up in the next ten days….Will get copies printed, and distributed to all members who own an airplane or a project, with the idea that these are the 'second rough version,' and I would like all to get involved in helping me make them a good set of rules… Refining them with everyone's input is the goal……Thanks go out to member and Pietenpol builder 'Smilin' Jack Fastnaught for working on this with me…....Ed

First batch of rules packages are in the mail…..Next batch will be mailed next Wednesday…The Procedural rules are not written yet, as they will depend on our different Competitions, which will be discussed at our forum this year at OSH. Procedural rules will include descriptions of the different contests, rules of passing, conduct on the course, safety rules and how to enforce them, and so on……..

Will consider a separate division for VW powered Sonerai 2 aircraft if we can stir up some more interest. Right now we have three Sonerai 2's with race numbers assigned. I purposely left the 'Sonerai 2 division' out of the rules package until we can collectively decide what constitutes 'a Sonerai 2'.. My opinion is that it must be VW powered, (Any c.c.), must have the S wing, and can be modified to single seat, but airframe must be same in general size, meaning wing area, fuselage width, wing span, etc. Since there were several hundred 2's built, I would think this would be an attractive option…..Would like to hear comments….Ed

No feedback on the rules package. I assume everybody is in agreement? We can tailor the rules a bit more, but not without an engine expert getting involved with me to do so. Trying to keep everything simple as possible…..Ed

I thought it was all very straight forward. I didn't see if it said shoulder restraints are required but may have overlooked it when searching. I also wondered about stock engine parts. One can surely find used original cranks, etc. but there are a lot of inexpensive aftermarket parts available. Some might prefer that availability over used original VW parts. Cases come to mind here. The cost of a pounded out dual relief case and the machining to get it right could easily match a new "super" case. I suppose the issue is that some of the new parts are junk and reliability is king. Plus assessing what might be inside an aftermarket case... Dave

Been away for a couple days… I will look at the rules this morning. I may have overlooked the Shoulder harness, as I grew up with them, and remember in the 1960's the EAA wanted everyone building an Experimental to have shoulder harnesses, as a 'pledge'…So I take it for granted. Just as if it was just a seat belt. We all assume everyone flying an airplane needs a seat belt. When it comes to rule making, I cannot 'Assume'…..!! I may need to specify 'No Cast Iron Crank shafts'….Hopefully I can get with some engine people to help clarify what is needed to be said….…..

Hello all, I am a Sonerai 2 builder. I am excited to find out I will be able to race with "like" aircraft. That is one of my question, how must "like"? What makes it a Sonerai 2 ? How do I get my hands on the rules? Maybe even a race number.
