Friday's the day for the FW190 and the red outrunner. Will my JS-18 handle the "round engine"? Or, is a PC 25 (or equivalent) needed for the boost in capacity? The Corsair was a hoot, but three flights and one "landing" was one of my poorest records. At least the park guys got a good laugh with their morning coffee. I'll probably keep the fuselage as a "static display" for my grandkids. My approach to these things has a bit of caution, but even as an old man it's hard not to get caught up in the "go big, or go home" mentality when so much performance is at your fingertips. Oh well, live, and pay more! See ya, Jack

Alfa Linkages


I would say from experience that you would need to secure the wire ends of the Alfa aileron linkages with a drop of CA or Epoxy or something else. Before I did (I just put a small drop of Epoxy on the end of the wire) I was able to pop them off the control horns on landings. Not all landings but depending on how rough they were, I could pop them off. Of course, I was caught up in the flying and did not know one side had come off. Talk about increased pucker factor! My next launch yeilded an FW 190 that would roll but very very slowly! I had no idea what was going on until I landed (Safely than god!) that I was only flying on one aileron. So, just a drop of some adhesive of your choice on the end of the linkage wires (not touching the horn itself of course) should keep this from happening ever again.

Pumi good point,

I use a little piece of that white tube ca'd to the end of the linkage..also a drop of epoxy at both ends of the bowdens. They may slip as well.

Sorry for your loss

I was sinking in the sand ...190lbs+ 42lbs.. does look funny though.

I had small lengths of the supplied plastic tube on each control rod end with a dab of CA. I believe I had problems internally in the right wing. There was a pretty large section of foam crushed, that was replaced, but I couldn't access the entire run of the control rod. Additionally, the spar had sheared in my last fandango which required a substantial amount of epoxy to heal. I put quite a bit of right trim in on launch, and it seemed to be fine. After throttling back, I removed the trim and it tended to roll right. I countered it for a while with left trim, but it just kept getting a more pronounced right roll--of course I didn't notice that I'd max'd trim out to the left, and was holding pronounced left stick by the time it departed the envelope and played tarzan. I was resigned to the fact that it probably needed some more tweeking after the surgery, but I couldn't resist seeing it dance the sky--only to fall on it's backside. Oh well. Thanks for the tip and I'm glad your FW made it back in one piece! Keep 'em flying. Jack

This sounds consistent with the control bowdens slipping and binding..
the same thing happened to me..kept adding trim to what was a perfectly trimmed model, and she kept wanting to bank opposite.. landed ,brought her home and noticed the bowdens were loose. I gently lifted the foam adjacent to the aileron servo and dabbed epoxy on the underside. released the tension,and the bowden is now anchored securley. Problem solved.
Good luck!

Swamp Fox,

I'll have to wait for a wind event to bring the rest of the wing down to verify, but that sure sounds like the ticket. Was insidious until it was too late--cooked this frog! I'm writing it off to the learning curve. Better next time--I hope. See ya,

Hooked On Flying!!!
Hey fellows I have been bending over the ends of the control rods on both ailerons and elevator. Not enough to cause a bind but they will not pop out either. I have had no problems with either the P51 or F4U using this technique. Got 15min on the F4U and 20min on the P51 this morning before the thunder showers roll in today. The meadow is getting pretty ragged and did a flop and flip with both planes today. No damage as the grass is forgiving but the spring back from the grass flips the plane over afer coming to a stop. The flying in the meadows days are numbered and fortunately i am almost done with my T-6 and can fly from the resort parking lot as it has landing gear.

Might be coming over the crest Sunday aftn, headed for Minden. Where abouts do I look for the airshow meadow? (Try not to hit my car). Jack

Going east on Hwy 50 just after you go through the casino corridor. As you come to the Burger King on the right after Kingsbury Grade you will see a very large meadow on the Lake side of the road. I usually use a pullout at the north end of the meadow along side the hwy. Usually fly in the AM before the winds kick up. If you come this way PM me and we can always fly up at the Heavenly Resort parking lot which is a great spot but requires landing gear.

Congrats on the stick time. look forward to your at-6 report.If it's like my Spit, you'll want to get that gear in a vise and rake it forward a good deal (if ya haven't already). a nose over on asphalt would be horrific with the scorps. Also be ready for big time torque upon rog...not that it'll happen ,just be ready.

Hopefully y'all (Jgentle) will meet up...too cool..

good luck !

Just finished putting the modified decals on and will let dry tonight. All thet is left will be a coat of Testors Dull Cote and install the pilot when he arrives by Friday and she will be ready to maiden. I have everything forward as the ESC is mounted on the back of the firewall and the reciever on the forward bulkhead. I also moved the rudder and elevator servos as far forward as possible about 2" on the servo tray. The battery tray is made so the battery will go al the way up against the firewall. I have not tried to balance but did weight it tonight and to my surprise it was 20.1oz without the 4.6oz battery pack. This will put her at about 25oz which is about 2oz lighter than I thought it would be. Will post some pics on the T-6 thread when all is complete. She came out very close to the planned paint scheme and will be very visible.

"Have Glue - Will Travel"
dawnron1's Avatar

I have the AXI 2212/26 with the radial mount, and I did indeed have to cut the cowl opening larger to accomodate the rotating motor. Swamp Fox was a big help to me in this area, thanks SF! Also, many thanks to tahoecrest for his help and advice! I also did add another mounting brace in a "t" shape behind the firewall on the bottom leg of the AXI radial mount; you'll find that the mount will only contact at three points without it. On the advice of Mike Connally, a modification that needed to be done on my Corsair was to glue in a "standoff" toward the end of the elevator pushrod tube. If not, the tube would flex quite alot when the elevator servo moved back and forth. Also, the aileron tubes were glued to the underside of the wing for the same reason(excessive flexing). By the way, this is the first maiden report for my Alfa Corsair; I've had too much fun flying it and forgot! My first maiden with Mike was a bit windy and with no decals on, my orientation was terrible. So after installing the decals and after my friend Tom adding a coat of water based urethane to them, I flew the "second maiden" of my Corsair last Saturday successfully with light winds and an experienced flying buddy beside me. And other than a slight trim adjustment, this plane is rock-solid and goes just where you point it. As many have said, it flies like a much bigger model, and on a 2-cell Lipoly pack, I flew at about 3/4 throttle for most of the flight. As far as landings, I found that cutting the throttle, and then adding just a little throttle with a tiny bit of up elevator at the end of a final approach gave the best landings for me. And I also found that even though I had both low rates and high rates set, that flying on high rates all the time was fine. And tahoecrest, you were right, it ain't a Formosa for sure, especially on three cells! However, I found that you can still cruise around scale-like as Sarge has said. Although I can't recommend this as a trainer, if you have experience with alierons, this is a very manageable airplane, just a little faster. I'm still getting used to the orientation thing, though. I found that the more sun you have, the better. I'll try to post some pics of my mods tonight. Thanks too all for your help and advice! I love the Corsair!

Congrats on your successful maiden and your working landing technique is similar to my own although because of my Alfa's being on the heavy side and the high speeds I fly at they may land a little faster than yours. I also have the dual rates setup on both my planes which work well for the slower scale like flying but at the higher 50mph+ speeds the high rate makes the plane to responsive and squirrley, but that is to be excpected though. Look forward to your pics and it won't be long before you may be seeking those high performance speeds that many of us are flying our Alfa's at.
