In the recent thread on Pukey Profiles and ply doublers I dropped a little hint concerning seeing PW's latest fly last weekend on both Saturday and Sunday.

Uh, there's a little more to the story...

Rick Cochrun and I were setting up at an adjacent circle, Paul was flying, his Dear Wifey having launched the model. Of a sudden all was quiet, although it's not such a shock when the only noise is being made by an electric model. I mean, Rick's whining over my insistence that he remove what I saw as quite a lot of right rudder was the loudest noise on the field.

Ah, but then I noticed Mr. and Mrs. Walker were surveying damage having recently been done to the model and doing that slow little dance wherein small parts hiding in grass are being looked for.

I thought, "Hmmm, this can't be good; surely that model is to depart for Muncie and then France within the next couple weeks."

Reluctantly I headed toward what turned out to be the crash site. First sight of the model--being held quite casually by Paul I must note--was enough to make one puke.

But I held my tongue and was almost instantly glad to have not uttered what I was really thinking. Because what I was thinking was that the model was toast: Cowl hosed, split motor mounts, surely the electric motor was junk...

Oooops! Electric motor, dummy! So that area of the fuselage which was torn up did not conceal major structural damage simply because the motor is mounted at the rear, the bulkhead quite possibly not being damaged. Or in any case a relatively easy fix.

And if you think about it, the nose area in an electric is more of a fuselage extension--a cowling if you will--and it carries very little in the way of load.

"I didn't see it, what happened?"

"I flew into my own wake. No problem, it will fly again tomorrow. The bad thing is that I broke my prop."

Honest, that's what he said!! Okay, maybe not those exact words, but I am real close of that you can be assured.

Well, I wasn't quite so optimistic. The CF gear was broken and while this could have absorbed some of the Impact, it could just as easily have transferred substantial loads to not only the gear mount but the fuselage as well. I was thinking the latter to be the most likely scenario.

Well, the three of us looked for small parts. Marked the spot, while PW was back in the pit area we came back and looked for small parts. Mainly as there was little else to do and if Paul wanted to go into a woe-is-me routine I was willing to give him some space.

Nothing untoward took place, when I strolled in the inventory of equipment and tasks for the rest of the day had been pretty well completed. And Paul's attitude was unchanged: "I'll have it fixed and be out here in the morning."

He packed up and left.

While I wasn't planning on flying Sunday I did call that night to see how repairs had gone and to promise to be at the field, even if just to do launch duties. I got there a little early and so did Rick Cochrun, who had intentionally left his mower in the van. Rick whipped that sucker out and had the primary circle fully prepped well before Paul was ready to fly.

And fly he did! Some structural damage was still visible, but I loosed the thing for the first flight of the day and he hammered it through a pattern.

Impressed? I was **really impressed** and I have been around this guy for a good long time.

Alas, all was not to the 100% level. New prop for one thing and I just now realized the piece broken 24 hours previous is likely the exact same prop I was using a couple years ago--on a Saito 56!

But model speed was the real issue as no matter how that electronic speed control knob was turned, the tacho didn't show the desired results.

Not a deal-killer; all new electronics had been ordered up on Saturday, were to come in Overnight Fed-Ex. I didn't ask how big a chunk new gear took out of the credit card.

There was a funny moment where during a flight the motor would make weird noises. This first happened in a maneuver, once it happened a couple more times Paul was just flying level waiting for the flight timer to kick in. Still, it made this mild retching noise one more time and so I yelled out: "Am I going to have to turn off my cell phone?"

Truly, all seems well at this point in time. Rick called last night to say that Paul had been flying Wednesday morning, evidently to avoid predicted thunderstorms which actually did show up that night and this morning. Prior to leaving the model was pronounced as having gotten its mojo back, fully ready for competition.

Ya know, I am certain a great many of us simply don't "get it" when it comes to the demands of competing at the W/C level. Heck, I don't fully "get it" and I have seen Paul's dedication time and time again over the years that I have known him.

So what? you say? Some guys have it, some guys don't. What's the point?

Well, I'll tell ya the point: On the world stage of CL Stunt competition, we are being represented by the best. Not just Paul, of course, but the entire team, even though Paul defines the competitive nature required, the dedication which is exceedingly impressive.

I think I'll call Mr. Rush tonight. Even though I have one 2008 W/Cs T-shirt and a matching cap, I'm thinkin' it might be a good idea to buy at least one more set, the proceeds backin' up our guys who are doing so much to represent us in the best way possible.

Paul wouldn't let a little thing like this slow him down.

Man, I hate hitting wake turbulence. Happened enough times to me. Nice to see Paul is human, after all. Glad to hear all is ready again.

Matt was complaining about it last night. Said he was seeing parts of his plane that he normally doesn't see in flight (and doesn't want to see). After 90 minutes he decided to pack up and go out again this morning.

Yup,

Wake is bad news, practicing at John Simpson's house about 2 weeks before the '02 Nats I hit wake turbulence with my Magnum just as I started the down leg of the second outside square, needless to say when I applied down elevator for the bottom corner, nothing happened and the airplane went exactly vertically (measured) into the ground bringing the career of that airplane to an abrupt stop/end.

Yes, I got quite a scare this morning.

Didn't Jim Casale build four or five airplanes, fly them all, and select the best two to take to the Nats? That must be why he got burned out!

As I recall, he flew four of them into fence posts in one year. That'll get you, too.

No - wasn't quite that bad, at least in terms of "death by fence post". Just two different planes, two different fence posts, two different years. And both went right a few weeks before whatever World Championships they were scheduled to make their debut (one was in 1986, the other in 1990).

Still stinks, anyway you slice it.

He did lose four planes in a row before the 1985 Nats, including the 1983 Nats winner. They all perished for a variety of reasons. Good thing the fifth plane was the charm ...

There ALWAYS more to the story. This story is not over yet!

However, the chapter not told here yet follows:
As you have read here, I him my wake turbulence on June 28th. It pancaked into the ground, and made many pieces. It was repairable, and with the aid of a new motor shaft, ran like new. The structure was examined carefully after the crash. The only damage was in the forward fuselage, where it was almost torn off completely. Since it was an electric, no sealing over bare wood was necessary, and it flew again the next day.

It was completely re-finished, and by Wednesday July 2nd, was done and back up to full capability. I flew it Friday, July 4th until my batteries were used up and needed recharging. I returned Saturday, where the wind was up form 10 to 15 mph, but flyable. I flew 3 flights, with no problems, and was going so well, I decided to put a brand new (fully broken in) battery into the plane for its first flight.

Once again, nothing exciting happened. It started with a good wingover with four tight flat corners followed by nice round loops, and tight squares and triangles. Again, there were no problems. The horizontal eight followed, and after completing the inside loop, the plane transitioned to the outside and at the top of the outside shook violently, and the inboard wing exploded. With the loss of the inboard wing, the remaining hulk rolled in and over the top of the circle, and punished the ground on the other side of the circle. This time, there was nothing but splinters left. It happened much faster than it took to read this. In a flash, my World Champs plane was gone. The only parts that I salvaged from this were the new carbon landing gear (key word, NEW) and the prop. The spinner was bent, but the prop survived. The motor, speed control, battery are severely damaged, and I do not know if they are salvageable. I’ll check some time after I return from France.

What happened? My best guess is that I hit a bird. There were numerous small swallows flittering around that morning. They have been there in the past, and I have had to dodge them before. The one thing about the electric is that it is quiet. With a 10 to 15 mph wind blowing, the bird may have never heard or seen the plane. I looked for a carcass, but never found one. The remaining pieces of wing spar caps suggest that the wing failed in compression on the lower surface. There is a section missing, but the remaining section indicates a failure in a splice area. This is not the weakest section of the spar by any stretch, so something must have initiated the failure. A small impact by a bird, while the spar cap was in compression could have deflected it enough to buckle. Nonetheless, it’s gone now.

I returned Sunday with the 2006 Impact, that finished 3rd at the 2006 World Champs. It still flies very well, and I even picked up a few trimming “gems” from the electric plane that helped this one as well. It now flies better than when I took it to Spain. Therefore, not all is lost, and life goes on. It did hurt for a few days, but I will not embarrass myself in France with this plane.

I would like to thank Kim Doherty for all the help in getting this project that close to the WC’s. He now has a new production processor that is for sale, and it works great. Kim also took it upon himself to get my batteries shipped to Europe for the WC’s. Without Kim’s help, I would never have even considered taking the electric plane to France. The restriction on taking Li-Po batteries on commercial planes is very severe, and I couldn’t even take a single battery on the flight. These new restrictions started on Jan 1st of this year. Kim, I truly appreciate all your help these past two years. Thanks you!!!

I would also like to thank Bruno Van Hoek for “hosting” the batteries sent to Europe, for me, at the WC’s.

Are electrics over for me…No way. After flying the 2006 Impact, I realized there is still room for improvement in the design of the electric plane. I will be thinking about what I need to modify to make it better, and get started on a new (electric) plane some time this winter!

The plane is loaded in its transport box, and on its way to Muncie. After the NATs are over, the US F2B team will be spending 4 days at Muncie to practice before heading on to France.

With a heavy heart, but strong conviction to do well in France.

Sorry to hear it, Paul. Your electric quest added even more interest to the WCs than usual.

Good luck - you can win with the experienced plane...

Tough break, Paul (sorry for the pun). I've watched the 2006 Impact fly and you're right, you'll have nothing to be ashamed of. It's a wonderful plane. Know that all your buddies in the Northwest will be pulling for you.

Paul,

Sorry to hear of your WC airplanes demise. It's never good when something like that happens. I'm sure you will take this adversity and turn it to a positive. I guess you can call your '06 plane the Phoenix since it is rising from the wreck of the '08 electric plane.

I was going to open by saying that I might feel worse about the loss of Paul's 2008 W/C model than he does. At least as indicated in his most recent post.

But of course it can't be a bigger deal to me than to the designer/developer/flyer of what was a truly impressive model. And while on this tack, Paul's reaction as per his above missive is **exactly** how he handles situations like this when friends are around. I mean, I was there the first time this model suffered damage; nothing but an upbeat response, the only stated regret having been the loss of a favorite prop.

Speaking of which, some of you might not realize the sort of power PW was seeing from his electric. Earlier I mentioned that it is thought the favorite prop is actually the same piece I had been using on a Saito 56. Now I don't have my notes with me but that is a real good Saito, sipping YS 20/20 fuel, and running so close to fully pinned it's not worth discussing, that motor would pull around 8400 to 8600 on the ground.

I think Paul was running it at nearly the same ground revs, and while the 56 could not possibly have squeezed out another 100 revs, from the sound of things the electric motor being used could have easily eclipsed the nitro-burner and by a fair margin.

Oooops! Sounds like Dirt might be interested in electrics!? Nope, not at all. I really like 21FPs and a real sweetheart of an engine--a RO-Jett 61 on pipe--has got me hooked on grease.

But if we count an early conversion of an existing Impact to electric, last year's model, the 2008 model, this was Paul's third shot a really getting it right. And the boy learns real fast...

So I was really looking forward to seeing how well what might currently be the world's best electric CL Stunt model--if due, apologies to Kim Doherty--in the hands of someone with Paul's track record would fare at the W/C level. And I mean this year, not 2010!

Alas, it is not to be...

Paul,
Sorry!
Bad things happen to good people sometimes.
I have every confidence given your determination and skill that you will do very well at the WC's and make all of us here in the States proud of you as usual.
Best of luck.

Sorry Paul! I was impressed to se your flights with electric. I really think it is future,But you have full capability to win with your Impact 2006. So LA with you! Best wishes on Nationals and W/C! Igor.
