Greetings from Nashville;

I'm sending along a race report from Lyman Slack of the Florida Club 40 race group. I can't attend as many of them as I could when I lived in Florida. I'll be racing with them at their next race on Oct 13 though.

Doug Bebensee



Lyman's report:

CLUB 40 PYLON RACES – 22 SEPTEMBER 2007



Near perfect weather greeted the twenty-eight pilot who registered. Air Boss Russell Stricker had his Chief Starter Ted Barker running the Judges’ Briefing and the Pilots’ Meeting right on time.

We knew we had some first-time racers on hand, but when Ted asked for a show of hands of who was in their first race, we were all surprised when we saw at least six hands pop up! One of these was Corky Prahler, who had his lovely wife Jan spotting for him. Special thanks to Jan for helping with registration and the matrix.

We had some great racing in a lot of the heats, and sadly, we also had some not-so-great crashes. A few of these were caught on camera by Wayne Darnaby. Jim Neelands was unable to make this race, but we’re sure he’s mad at the way some flyers just don’t respect his love of the pylons! In fact, Chuck Rodel and Ted Barker both managed to test the strength of their racers against the pylons. Chuck won this one as he managed to at least take part of the #2 pylon down with him; the #1 pylon won when hit by Ted’s model. Ed Smith’s new racer in USAF livery fell to a mid-air with Larry Ralston. Russ was in a mod-air as well, but managed to limp home with minimal damage.

For the number-cruncher out there we had racers from seven clubs, including for the first time from the Hernando County R/C Club. During the twenty heats flown, there were 12 pilots winning at least one heat. Jerry Dittmar and Tom Craig had perfect scores, winning all three of their heats. Bob Holbrook qualified for the Gold Heat with 11 out of 12 points. A fly off was necessary between Chris Wieland and Herb Chutter for the final spot. Herb, in his first Club 40 outing won the fly off and advanced to the Gold.

The Gold race was one of the best we have seen, with Bob Holbrook flying a near-perfect course to win, closely followed by Herb Chutter, Tom Craig, and Jerry Dittmar.

After the awards, John Castronover and Bob Holbrook flew a five-lap demo race pitting the Gold winner against John’s experimental “E-Racer”. The speeds were very evenly matched, but Bob flew the same great course to win.

The venue for the October 13th race will move to Archer Field, home of the Flying Gators. Will Honest Ed, Jim Neelands, and John have the home field advantage? They say so! An announcement was made that as promised last year; this will be the “Oktoberfest Race”. If you get hungry early, bring some snacks as no chow will be served at the field. Instead, we will race straight through and after the Gold, all of the participants (flyers, crew, and workers) will be invited to celebrate Oktoberfest at Lyman Slack’s home, not far out of the way for anyone, where complimentary brats, bread, kraut, and brews will be served! Details later.

Here’s the link to a slide show from September’s race:

Here is a heads up on Sky Raider II defect that resulted in complete loss of control and a crash. The covering at the leading edge of the wing was poorly ironed down and did not adhere well to the wood or the covering underneath. There was a very slight, if any, overlap of the top covering onto the bottom covering. In flight the leading edge of the top covering pealed back about an inch and became a spoiler resulting in loss of lift on that wing and the plane spiraled in. The seam of the top covering was right at the leading edge of the wing and air got under the covering and pealed it back. Once this happens you can no longer control the plane.

If anyone has had an unexplainable loss of control and crash, this may have been the cause. I now cap my wing leading edge with a one inch wide strip of iron-on film so that the leading edge is completely wrapped the entire length of the wing. The fix at the manufacturers end would be to wrap the top covering around the leading edge at least 3/8 to ½ inch onto the bottom.

Don, I’m sure that you can get this fix implemented. We crash enough planes while racing without the manufacturer designing crash bugs into the plane.

I have also had this same defect that resulted in very squirrely handling -- I was able to save the plane by immediately cutting power and nursing the plane back to a "very exciting" landing. In my case the covering on one wing stripped back about 2 inches -- and was also not wrapped past the center of the leading edge. There was 1/4 to 3/8 inch overlap on the bottom covering, and I had previously ironed down the compete leading edge to insure this problem would not happen (I thought.....).

An interesting aside (which may be the whole problem) -- when I stripped the covering off the wing, I noticed areas along the leading edge and other areas on the sheeting where the the covering AND adhesive came away clean from the wood -- and other areas where the adhesive stayed on the wood and came away clean from the covering film. What I saw tells me the root cause of the problem is that the adhesive being used on the current Toughlon covering IS NOT STICKING ADEQUATELY to either the covering film OR the airframe surface.

I have also seen areas on the fuselage where the covering film has pulled away from the adhesive, so it appears the problem is not limited to the wing graphics covering material.........

Bob,

I've passed the information on to the manufacturer.

ToughLon is available in Clear. Contact me via email or private message with your US mail address and I will provide a 12" x 30" strip for a very nominal fee. You can use it to wrap around the leading edge. I think I'll start doing it just as a preventative measure.

We will monitor the situation. So please contact me if you have any issues with the covering.

One thing to note is that the solid color Sky Raider Mach II ARF kits have CA hinges. If you prefer another type of covering, recovering the solid color planes is easier than the pre-hinged standard colors.

General engine/class question:

What do folks think of making a 4stroke Raider Club40 class?

The Magnum52 4stroke is nowhere near the powerhouse an OS is, and may help some fields overcome Noise Concerns of screaming 2stroke racers. I havent really looked into it too much, but I did fly a Raider with that 52 and it seemed less powerful than the GP42, yet flew the plane around just fine for sport flying. And of course its cheap for a 4stroke, which I'm liking.

Anybody interested in integrating spec Magnum52 4stroke into Club40?
or does that just not fit the concept of Club'40'

I did not include 4 strokes in my original Club 40 draft because they are a little more expensive, and they are more prone to damage in crashes.

I picked up some of the Magnum 52's while they were on sale. I've only run one on the test stand, but it seems to run well. I mainly got them because we have found it to be a good engine for The World Models Ultimate Biplane. But I think they would do just fine on a Sky Raider Mach II. I've thought about trying it, but I haven't had time.

If your club has noise concerns and you can get guys to put Magnum 52's on Club 40 planes, go for it. Club 40 is about having low cost racing fun. If 3 or 4 screaming TT Pro 40's make that impossible for your club or area clubs, I think the Magnum 52 is a fine choice. I would stay with a single engine if you do 4 strokes because they vary more in design and power curves than sport .40 two stroke engines.

Thanks for the quick reply.

I had a chance to speak briefly to a local Club40 guy today,
and he said ( I'm extremely paraphrasing) the 40 displacement spec was something to take seriously for a few reasons.

Oh well, just a notion I had & figured I'd ask.

What impact would larger engines than .40 (whether 2 OR 4 cycle) have on our present waivers and setbacks...at least in Texas?

Our present waivers are based on specific engine displacements and airspeeds.

We can not use larger than .40 CID and airspeed is limited to 100 MPH average.

Use of larger engines would require the set backs in the R/C racing competition regulations for the specific engine size. **

For engines larger than .40 cu. in. this would be:
450 ft. pylon line to pilots
550 ft. pylon line to judges
675 ft. from pylon line to spectators

The regulations do not differentiate for 4 stroke engines.

** or we would have to go through the process of getting a new waiver for all the fields using the current one.

Waivers allow for deviations. http://www.RCProWarbirdRacing.com uses engines larger than .40 and we get waivers for a 275' pylon setback. with a 150' deadline.

Engines larger than .40 would require a new waiver from the Texas group.

One reason I have proposed the 1.5 mile, under 100 mph courses is because speed is more of a factor than engine displacement.

I did not realize that KidEpoxy is in your area. I don't think that introducing 4 strokes in your area is a good idea. But I don't see a problem with it in places where clubs are noise sensitive and 4 strokes are more acceptable. For electric only clubs, I see no problem with using electric power on a Sky Radier Mach II either.

Chuck,

You guys have a good thing going, and I don't think it would make sense to apply for new waivers. Unless you add 424 and the clubs can handle bigger setbacks. No reason to muddy the waters.

KidEpoxy,

I didn't see that you were from San Antonio until I read Jim's message. Since the San Antonio and South Central Texas clubs are already running the Novice and Advanced classes, it would be best to stay with something you can race in their league, in my opinion. They have a real good thing going. An OS 40LA is not much louder than the Magnum 52 if any, and probably yields about the same speed.

If you want to put a Magnum 52 on a Sky Raider Mach II, go for it. And have fun flying it. Let us know how it does. Maybe Jim can radar it.

I may wind up putting one on a Sky Raider Mach II to test, or give to my Dad. I got him to fly R/C for the first time in 23 years on Friday evening. He flew a little foamie, but he had fun and did great. I think he might like the sound of a 4 stroke on a sport plane. Or I may just put the Magnum 52 in a World Models Clipped Wing Cub that I'm already putting together as a gift for him. I would be curious to see how a Sky Raider Mach II performs with the 52. But I doubt I would promote it for racing unless it solves a significant problem for some clubs.

I dont know about racing,
but the Magnum52 4stroke flew the Raider around ok when I had one back in 2003/4. Did all the basic sport stuff, but not what I would say was impressive power, good for aileron trainer type stuff... or just casual flying with that 4stroke sound. I did feel it was clearly less power than the GP42 it replaced, and after a Dumbthumb Doink the GP42 was back on & flew the Raider much better.

Anyhoo,
it was just an idea that popped into my head,
and again Thanx for the promp answers guys.
