While I’m thinking of covering ideas the wing is now joined. I separated the hardware I’ll use on the left and the hardware that I won’t use on the right. Obviously the decals are not usable either. It is amazing how kits have changed over the years, this design is sleek and cool, yet the components and construction aspects are very dated. I hope it makes me smile on high speed passes…..also the wing blocks were tapped from the factory which is something I have never seen before….very cool

I built this plane a few years ago. Like you I didn't use the plastic cowl. I bought a half built kit at a swap meet for $25. The fuselage was already built mostly. I only had to build the wings. I made the front wheel turnable by putting it on the back of the firewall. I didn't like the how the ailerons are wider at the tips and I was worried about flutter. But I made them too skinny. Maybe a half inch wide? Too small. On the first flight it wasn't enough to control the P factor and it spun and the right wing hit the runway. I thought I had reversed the wing servo. But no, they were fully deflected. Just not big enough. Nice looking plane though. I found another kit. Someday I'll try again.

Glad to hear from someone that built and flew this plane. Thank you for posting.
I cut the ailerons yesterday and they will be full size, but I am thinking about flipping them from what the plans show. They would be similar to a 4-star which are wider at wing root and taper towards the tip. I will dial in the expo but have a decent amount of deflection.
At higher speed low rates could be used.

Let's see what else I can remember. The original builder made the fin much bigger. He also moved the stab higher. I think it's supposed to be on the bottom of the fuselage? He cut a notch an inch higher. I made mine look like the star O.C. version. Kind of. It was passable. I really like the 25 size planes. I could put it in my trunk without taking the wing off. Just throw it in and go. Pissed me off when I crashed it. Can't wait to see what yours looks like.

Appreciate the input, never met anyone that built or flew one, and Google shows nothing for pictures of a built one.
25 size planes are a great size, but I have put 40's on every one I've built, not stupid fast, just enough to get your attention.
Overall design of this plane is sound, but many things need changing if it is to hold up to my flying style.
I'm concerned of the lack of rigidity of the fuse from wing saddle back, thinking about putting a small stringer on each side to stiffen it up a little bit. The rear fuse sides are too flexible in my opinion. I changed the landing gear wire and gained over an inch of ground height.
Here is a pic of a Jack Stafford kit I built, may cover it something like this, bright colors for old eyes...........

I can't remember what the name of this Stafford plane was..........can't find one of these anywhere either

Stafford kit I built

Ailerons are hinged and installed and wing is mounted so I will be using the supplied wing bolts and hardwood blocks, was not sure if I was going to change out that hardware or not. Getting closer to getting a start


ing cg and overall weight. May have to build in a small weight in the aft fuse in order to balance it correctly. I did go with the 4 star style aileron set up.
All up weight so far is 2 pounds 5 oz. I may not make the 4 pounds goal. I still have radio gear and covering to go and have 1 pound 11 oz. to spare..

That sure is a pretty little airplane. You can tell it was designed at the end of the control line period. It carries extra wing ribs. As far as color goes, I made the mistake of covering a plane in blue. Once I got it up in the air I couldn't see the thing.

I understand and agree. My eyes only see the bright stuff anymore. Here is what I flew yesterday, kinda sad actually I can’t go from horizon to horizon anymore as I almost lose orientation and this helps a lot.

A little color…and there are no flaws unless you can see them at 100 mph........

Here is the top of the wing. I did a great planes tracer using these colors several years ago and it shows up good in all weather. Remember don’t look too close….It’s far from perfect.

Plumberdeluxe, Your build of the Olympic Challenger is the first I seen. Nice build and looking forward to your flight review. I have this kit also and may build it this year thanks to your build.

As for your Jack Stafford plane, it's name is Tom Kitty, 25 and 40 size. I built the 40 size in the late 80's and lost it on the first flight. I did a high altitude snap maneuver which ended up in a inverted flat spin and the plane would not recover from it. So I just watched it spin itself into a freshly plowed bean field. If I had thought about it and reacted sooner I could have caught it before it hit the ground. I took my daughter and niece with me. My niece acted as a reporter and did a blow by blow and interviewed me about the crash. Crazy kid!

Nice, Thanks Ron I appreciate you popping in and checking it out. Usually this time of year I wouldn't be building, but after looking for a build or finished picture of one of these planes, I came up empty and decided to build it. It's dated perhaps but I think I can make it usable and fun to fly by making a few key changes. Thanks for also kicking my memory into place on the Tom Kitty, it was the 40 size with foam wing and an sf 46 pumper. I'm just poking along having fun at this one............hope it flies good!

Well I don’t care for the way this turned out, I’m going to be able to see it but can’t hardly stand to look at it. Sometimes stuff just don’t go the way you want. I’ll finish it up and fly it but man it’s ugly.

Dude it’s sad actually but it is what it is. I’m feeling sorry for myself. So I just got the engine compartment fuel proofed and wing servo installed. I am hoping for 3.5 pounds RTF.

hey It's LOUD.....and more importantly, you will not see another one like it at the flying field!
Like you said, you should not have any problems seeing that puppy in the air.

I still give it two thumbs up...
Maybe if you added some of that blue at the wing root area to blend in what you have it would smooth that eyeball twist out a little????
or not...it's not going to make it fly any better and that is probably the most important thing..

I am really enjoying this build and the others you have done. Nice work. I do have to say that while looking at the color scheme, I seem to hear the theme from the Partridge Family playing in my head.

How does that song go? “Cmon get happy” We’ll I guess this thing is “happy” without speaking a word. Just remounted the engine and glueing the stab on, guess I’m committing the the Loud covering version of the Olympic Challenger. I have very few decals to add but let’s face it, this pig is super busy without any…..anything! Love the comments, keep ‘em coming….

Ok plane is now assembled with a few items left to go. I came up with a weight of 3 pounds 5 ounces with 3 servos, batt pack, receiver and switch to go. I did have to add 2 ounces of tail weight. I’m going to be close to the 4 pound goal.
