The amount's something that the organizers will have to sort out. Too little, and nobody goes in; too much and it's too easy to buy a trophy. Setting that amount is above my pay grade

This is the best idea ever. "you need to build your plane to these specs, and keep in mind, that your plane can be claimed at any time" Claiming rules are the best way I've seen about ensuring an even playing field.

The actual amount needs to be enough to discourage the practice, but not so high as to make it ~never happen~. It needs to be a real threat. In some racing series, if you claim someone is running a cheater engine, you pay for the gasket seat to get them to teardown the engine.

In LeMons racing, you can can have your car bought for $500 at any time. Just throwing it out there, Say 200% materials cost? I need to do some drawing again, and work on the engineering. 3.

A low-powered racing class around a standardized industrial V-twin class or even the tried-and-true stock 1600cc VW would be a great place to start. With such modest power, aerodynamic cleanliness and careful piloting would determine the outcome, not big dollars. Maybe a claim price of$15,000 or $20,000? 4.

They're actually pretty common in the horse racing world (https://www.toba.org/owner-education/claiming.aspx). 7.

If it's the former, great: it will tend to give priority to good build quality and good piloting. If the latter, it would give more scope to creativity. 8.

Mar 6, 2016 ### autoreply ### autoreply #### Moderator Joined: Jul 8, 2009 Messages: 10,732 Likes Received: 2,542 Location: Rotterdam, Netherlands I'm aware of them (almost exclusively on your side of the pond). The difference I see is between people winning due to big$ investments and people simply being cleverer or working harder on stuff. I wouldn't want my airframe work to be up for sale to the highest bidder. Say 2K in material in there, but hundreds of hours of work?

That's where just doing your bidding system on the engine system might work out. I feel that the engine is the only aspect of the airframe where putting in more money improves your performance markedly. Just having to give up your engine if desired for a fixed price (say 20K for a O200 in F1?) makes a lot of sense to me, just not including the rest of the airframe.

Given that the VW derivatives are the only engines that are proven and have a significant lower price point as the O200, Rotax 912 and the ULpower's, that's pretty much the only way to "cheapen" it up. Instead of complex rules; simply limit fuel consumption during the race with a universal amount of fuel you can use. If you cap this, have a steep but fair penalty for using more and you don't need complex rules to avoid expensive engine mods.

Can you tell us more now or do we have to wait until Osh?

Why not? If your plane is so much superior that you always win, it gets bought. The next time the competitor wins in your plane, you just buy it back. If you win because you are the superior pilot, you still win in the other guys plane. The claimer generally has to have placed in the top 3 spots to be able to claim the winning machine and generally has to surrender his machine in exchange.

If you are really smart enough to come up with a far superior race plane, within the spirit of the rules of keeping things inexpensive, then you are probably smart enough to not win often enough, or by enough of a margin to invoke the claiming option. Many claiming races have clauses that say you have to win by more than Z% or 3 out of 5 races before the other racers can use the claiming rule.

I do understand the sentimental desire to keep the machine you spent so much time, thought, and money to create: but this is racing! Emotion should have no place in the equation, just like good engineering. One poster on the RAH site one time made the comment that "anything more than good enough is unprofessional". This applies to racing as well. If you have better ideas you never implement all of them at one time. Just use what you need to win that one race. When the rest of the field starts to catch up you just take the next step up - but only use part of it :devious::whistle:

Supervee Air Sports is a continuation, of sorts, of the very successful low cost racing class called 'Formula Vee' which existed fro 1977 thru 1997. It is a 'Formula', with VW based air-cooled engines, 75 sq. ft of wing area, at least two 500 x5 tires, cockpit width and height restrictions, cockpit visibility requirements., minimum empty weight of 450 pounds, strength requirements of a minimum of 6 'G' + or- , and more details….………We have a small core group building new racers, or re-building old Formula Vee racers, Most notably the Sonerai 1, and the Wittman V-Witt, and two are currently flying with registered race numbers, ready to race. A half dozen more are in the works. We are on Facebook…'Supervee Air Sports', and we are also on the 'Affordable Air Racing' pro boards site…..I feel that we may have already talked about this on this site, but I am continuing to promote the completion of new aircraft, so we can return to competition in the next couple years…You can build a flyable Sonerai 1 for under 12 grand, complete, if you watch your spending….In today's world I find that affordable..Ed Fisher

Back when I was young, a long time ago at the local dirt track they had "claimer" races. Anybody could buy a race car (a claimer) for a set price, this prevented people racing in that class from spending to much on there car to be competitive as it was likely to be claimed and then raced by there enemy the following week. By extension if a class of "claimer" aircraft was established by the nature of the class it would prevent those participating from investing more than the claimer price established and would (I think) be a hoot.

I went back and looked thru the other , similar topic thread about cheap air racing…..hmmm….44 pages. This ones at 19 and growing. Some interesting and intelligent ideas. But no progress. However,,,,I know what was really inexpensive, and it still is. The little VW has so much going for it….And we are progressing and already have a group preparing several airplanes, to 'race cheaply'. Check out 'Supervee Air Sports' on Facebook…..Ed

The big idea behind the CAR-251 is to be frighteningly simple to build. Both for the ease of verifying the design is a CAR-251, and for low effort building. A square fuselage, with flat top rails. A wing that builds on a flat surface. Etc...

If any given plane is "much faster", there's something that would need looking at there... Realistically though, I'd like claiming to be "engine first". It wouldn't even need to be flight.. a dyno could tell the truth there.
