Class C

There's a little article on C Class at:
http://reocities.com/CapeCanaveral/G...4707/index.htm

I'm copying the text here (who knows how long the site will survive...)

"""""""""""""
"""""""""""""
This article by D. Pickard has been kindly forwarded to me by "dedstik"and "Steve-O-Bat". Due to the original photocopy dropping out in places, the strain on the emotions and patience of hand typing it from an e-mail to me, my corrections to American usage of some spelling, and minor revisions of syntax and grammar, there may be some differences or omissions, however the core of the notion is here.
..................................


The incredible sound of racing 60s on high nitro brews at top speed on the end of long lines will be heard again in Australia.

C class team racing was unique to Down-under modelers during the 1950's and 1960's when it was a top drawing card in any competition day. McCoys and Doolings would fight it out for outright honors against smaller engines that countered lower speed with better economy.

The move to recreate this spectacle kicks off with Vintage C class team racing's first public airing set for the last day of the Australian National Championships in early January 1996. "That will be a demonstration to ensure as many people as possible witness the most awesome sight in team racing," said Ross Filshe of Melbourne, the man behind the move to re-introduce 10cc racing. "A circle filled with flat out McCoys or other 60's rocketing around on 70 feet lines is an experience no one ever forgets."

The rules for Vintage C will be very similar to what was used when the class faded 30 years ago. The cut-off date for plane designs will be 1965 with a minimum wing area of 250 square inches, a two wheel undercarriage with 2.5 inch diameter wheels and a minimum fuselage cross section size at the cockpit of 4.75 inches deep by 2.5 inches wide. The plane must be in the spirit of the event in the way it resembles a full size racer with a conventional cowled engine and the pilot having forward vision.

The engines must be from 5.01 to 10cc and of deflector piston type with no Schneurle porting. Fuel mix is open, but the tank must be no bigger than 60cc.

The event will be flown on 70 feet (center to center) lines of 18 thou thick from a metal handle that has a safety thong around the flier's wrist.

"One of the most vivid memories I have of this type of event," Filshe said, "was seeing so many cut and bleeding fingers as the McCoys bit back at pit men. We can't have that these days, so electric starters are being permitted."

Former Nats Winner, Ken Taylor, said the class eventually sorted itself out into two distinct areas, those with specialist .60's which fought bad fuel economy and difficult restarts and ordinary large stunt motors (35 to 45) which were handicapped with only 45cc of fuel. "We often saw the situation where C team race was the last event of the day where a lot of stunters would take out their engines and refit them into big team racers. Popular engines were OS Max 35, Enya 35, Fox combat 40, and I remember a Kyowa 45. The 35's ran on 9x8 props and the 45's on 9x10's which contrasted with the 60's on 9x12 or more.

"On the right setting, everyone stood a chance of winning. I. .....not legible on poor photocopy, sorry!
out a National with a Merco 35 powered model called a Cre .....not legible on poor photocopy, sorry!

Ross Filshe said he sees Vintage C team racing in Australia will become no more than a high profile demonstration indulgence of a handful of enthusiasts. "I don't expect we'll get anywhere near numbers of Vintage A or B but we've got enough enthusiasts with big fast 60's to put on a good show."

These are big planes that fly very fast and make a heck of a noise. They also pull like the powers of hell on the handle.

"So far, those interested in having a go are looking at 60 sized engines such as McCoys, Doolings, OS, and Enya from the period with later big ones including Super Tigre and replicas of older-style 60s such as from Stalker. I doubt anyone will use a 35 as that would be too close to the 29s currently well catered for in B class," Filshe said.

I don't know if anyone is racing that class now. Maybe it is too much of a good thing?

This is a great posting, I would love to hear from anyone partaking. i think that 60 size "C" category can be the ultimate Team Racing due to the beauty of larger racers and the audible and speed effect. Let's hear more from individuals involved.

An American Class B racer from the 50s: Blunder Buster, designed by Ron Schuver and published in Air Trails, March 1955.

The plan is not CAD quality but looks quite useable.

My old clunker

Here is a picture of an old racer that I picked up long ago. I had two of these at one time but cant remember what happened to the other.

hmmmmm..... you have two engines and pans but just one airplane. Makes me suspect something unpleasant happened to the other one.

Can you tell more about it? What engines, does it have a name, who built it, when, ... ?

(I'm sure I could think of more questions )

pertime,

First off let me thank you for all the plans and pictures you have posted of team racers. I just love this stuff! I had two planes and one I just trashed ( bad shape). I also had three motors and a bunch of parts, all ETA's. Traded one ETA for some other diesels and as you can see I still have two left. Also have an Oliver MK.III. Can't tell you anything about the plane as I picked up everything at a sale just to get the motors for my diesel collection. Any one need a ETA and pan for a trade on something similar????

What do you do when you need to travel with your racer?

You make a box for it:

This year I have actively revisited my humble control-line beginnings. At 54 this has been a great gift to myself. It has cost me none of my RC interests but has added a dimension to my fun that I have missed for decades. I never did race U/C but have wanted too. It's going to happen now. Your generous gift of so many plans and information (thank you for all the time it took to do this) has come at a perfect time for me. I hope others are revisiting their first loves of model flight, whatever it may be, as it has been a rebirth for me that I would wish for others to experience.

Your thread and the other large plans thread have a added a fresh appearance to a breed of of models that will survive the test of time better than the arf of the month. I have my small share of arfs but they won't be eulogized any longer than the trip to the burn barrel.

I was lucky enough to find a club that has a strong control line following and the members are fine gentlemen all. And some great Gals! If you can't find a local club right away there are several good stooges on the market. Free flight power models and indoor rubber are great fun as well. I wish I could do it all. I'm trying.

Cheers.

Pentti Nore has now posted some photos of his later models from 1980s. Just like others who wanted to win, he went for flying wings. The wing models are superior for winning but many dislike them esthetically. To me, these still look pretty good, and they are made out of wood unlike many current designs.

He also included some clear photos of what is "under the hood" of those later models. What seems pretty significant is: no pan or even metal plate. Instead there's threaded metal inserts glued straight into the wooden crutch. This is stable enough and saves weight. Lighter weight means better acceleration, which can save the fractions of a second that you need to win.

Beauty of course is in the eye of the beholder but personally I find the flying wings just as graceful as the classic racers. To me, it is a natural progression of "Form follows function" and I find them to be very gracious in appearance.

Engines for Racing

I have long been facinated by these designs. A couple I want to build are the Perky and the BlunderBuster. For the .29 Or "B" Class I have 2 Enya .29. A 5103 I think, and a newer Enya .29 Model 5225. I have an O.S. Max .29 and an ST.29. Will these engines be adequate for B T/R. I should know what an ETA is but have never seen one.

I have a Veco .60 C/L engine that I would like to put in a vintage C T/R. A lot of these engines, while they work well have been used except for the new ones, but I want to experience the cool old models. I would T/R with no visions of grandeur for the sheer fun of it unless, this is the predicate of my inquiry, or should I buy better engines? Not likely to buy many. For A T/R I have A Webra .10 and for .15 sizw racers only Enya .15's and .19's. There are six Enya CX .11's and a couple piped that were RC and are as new. All engines, especially the older ones are dedicated C/L and the others have been converted to C/L including an Enya .60 Model III NIB but I was thinking about a Strega for that one.

Observing rules and etiquette, will these engines do?

And thanks for the Perky Plan. I want to build a Perky. Our club also does a big Musciano Event. Any of the smaller hollow log type plans would be really appeciated.

Thanks, Bill

For engine eligibility, you should check the rules that are in effect in your corner of the world.

Assuming you are in USA, you can find the rules at http://www.nclra.org/ . For Class B, it says:
"Any single bypass up to .29 cu. in., or any engine up to .28 cu. in. Full wave tuned pipes are prohibited. Mufflers, or exhaust extensions which do not increase engine performance will be allowed."

I've understood that getting the engine to run well (fast and economical, starts easy) is more important than what engine, exactly, it is. If it seems that the engine is keeping you from winning (as opposed to you keeping the engine from winning) then you might have to look for something new

Some article mentioned that people would take the engine out of their stunt ships and bolt it into a racer for C racing. I haven't heard of anyone doing any C racing recently. Just some scaled up Dalesman's built just "because".

Thanks for the reply

I understand what you have stated and the racing for me is for the enjoyment of the models I never had the opportunity to fly back when.

I am in Canada and our rules for the most part are the same as American as far as I know, with a couple little deviations that are being worked out so that we can compete with the southern neighbours without making the unacceptable deviations that we have worked into our routines that snag us at American events and keep them from coming here so they don't make the same mistakes which is all it comes down to. 1.5 laps between two certain maneuvers always gets us in the US as it must be 2.5 there because of the 2 lap rule. It makes sense to me to do it one way or the other. But the same for both countries.

I like the looks of the Dalesman? Are there plans on hand for it? Thanks for teh little Perk Plan on page one. I have been looking all over for that plan.

We have so many events and I am only familiar with some of them. A newby to a 54 year proud club. I know they run Perkys and have other races. The Fox .35 Race is fun but the LA .25 is allowed also and I would prefer that we stick to Fox for that one or have a seperate LA .25 all else being equal. With the vissisitudinous nature of pitting it would be hard to figure out if it were me or the motor. But maybe not. Engines are more consistant than I am.

Thanks for the info, Bill
