I haven't seen a CL scale kit for that plane but there is probably a RC scale plans or kit that can be converted for CL scale. Due to the lack of dedicated CL scale kits for many years we can been converting RC kits over to CL scale for a long time, it works I fly the great planes RV-4 (56" span kit) with no problems.

Many years ago, Consolidated Models, Inc. had a 41" span CL kit of the Avenger.  Although long out of production, you may be able to find plans for that one on the AMA website or elsewhere.

The AMA Plans service lists several Avengers.

One is a 64 inch RC model from Model Akirplane News, Dec 76.  Also a 26" Profile for CL.

thank you gentlemen for the replys,i am looking forward to enjoying control line full time now as i have left rc for good,interested in scale and the TBF will be my tribute to the flight 19 Boys,,,

Butch, the hardest part of the conversion will be running the leadouts and mounting the bellcrank.

Just mount the bellcrank as close to the CG as you can while still having a straight run of the leadouts, keeping in mind that a free and low-friction leadout installation is more important than getting the bellcrank nailed down right at the CG.  Then make holes in the ribs (if you want the leadouts in the wing) for the leadouts, put in leadout guides, and proceed.

If that plane has the dihedral angle that I remember, I would be tempted to mount the leadouts externally -- put the LO guide on top of the wing tip, put holes in the fuse for the leadouts, and mount the bellcrank above the wing.  You'll lose some looks (and possibly scale points, if you compete), but you'll gain a lot of ease in assembly.  Then for your second scale CL model you can mount the leadouts in the wing.

You should also find it helpful to study as many magazine plans as you can, to find design elements that you can copy in your conversion.

Unless you have built a low wing model with dihedral and had an unfavorable experience with the bellcrank/leadouts in the wing, I suggest it is not a good idea not to recommend against doing so.  It has been done on scale airplanes, even semiscale stunt ships with no problem.  Since the possibility that inverted flight will not be flown with the scale airplane, there is little or no problem with the vertical CG and the bellcrank/leadouts can be placed in the wing, in most cases, with little or no problem.

Just saying.  And yes, I know what I am talking about.

But you don't need to ask how to do it.  I was aiming my post at Butch, who apparently cannot just look at a set of plans and say "ahh, that's how to do it!"

Me, I'd go ahead and whack holes in the inboard wing ribs as appropriate and put the leadouts and bellcrank inside.

So, which is it?  You first recommended putting the bellcrank/leadouts above the wing, now you say you would put them inside the wing (which world just fine).  I would also recommend putting plenty of tip weight in the outboard wing which I think is a good idea for any CL scale model.

Keith, what do you recommend that an absolute beginner to control line fly?  A 150mph combat wing?  A 200mph speed ship?  Or maybe a trainer?  If you say "why, a trainer, of course", then either you only fly trainers, or you think that a recommendation should be aimed at the abilities of the person being recommended to.

I recommend to Butch, to whom it is not obvious how to convert an RC ship to control line, that he run the lines above the wing, because it is easy.  If Butch had been designing and building model airplanes for at least 40 years, and I would tell him to put the leadouts in the wing, because it is pretty.

Butch -- do keep in mind that I'm just making suggestions here.  If, after thinking about things, you're comfortable with putting the leadouts in the wing and you can see how it's done -- go for it.

Tim,

I was not recommending any kind of airplane.  Butch has already told us he wants to build a scale Avenger.  And he has told us he has built model airplanes before.  So I think it is safe to assume that he knows enough that a scale airplane is certainly not a combat ship or a speed ship or whatever.  Yes, you explained that it would he would "gain a lot of ease in assembly".  In my opinion, there is not much to be gained in the easiness.  You still have to have leadouts, then, you have a leadout guide (in this case on top of the wing) and that does not help make it any easier to finish and paint.  As far as performance is concerned, there is no advantage to have external leadouts and an unsightly leadout guide on top of the wing.  And you do not need to have "40 years of experience" to mount a bellcraank in a wing.

I was just suggesting that there was no technical reason to do what you recommended. Besides, I think it is a matter of opinion if it is easier to have external leadouts with a tip guide than putting everything in the wing.  For me, it is easier to paint the thing with the controls buried than if you have to work around the leadouts and a tip guide, or even if you have a removable guide and detachable leadouts (which is some cases is necessary, like for highly swept wings and such), but that is a whole other subject, beyond the scope of this discussion.  Just as beginner's airplanes and combat ships and speed shps are beyond the scope of this discussion.

Suggest you lighten up just a bit.

If doing it as a profile interests you at all Don Hutchison's C/L profile stunt version is a very scale appearing design that would be an excellent flier. It wouldn't take much at all to make it into a competitive scale model. It's also big enough to present well with out being so large that it's difficult to transport.

I was thinking the same thing. Detailed out, it would make a nice Profile Scale.
