Andy, the bellcrank could be a Perfect item, they were plentiful and inexpensive. Still have several small ones in the package, made for 1/2A.
Great info and nice craftsmanship being displayed.

I need to set this aside for a bit. I'm building a model for a raffle at the start of June and just realized how close that really is!

I might be a little overdue, but I'd recommend the Juno fin.
Nothing against the Stilletto though -on the contrary-, I saw Les taking his first World title with it, just preference....

@Andy: how's the shoulder doing? And the raffle model? As we'd like to see some progress on your CL project too...
Anyway, one of my RC pals, Niek, is sending his regards. He's helping me out on my first attempts in beating some mini Arduinos into submission in becoming CL timers/controllers. Nothing spectacular though, as yet.....

Shoulder is improving. I was able to hold my transmitter and fly 2 minutes two week ago - then I had to hand off the transmitter to my son. The weather hasn't cooperated since then.

The raffle model is coming along. The thread for it is here: https://www.rcgroups.com/forums/show...Grumer-Grandpa

I correspond with Niek on occasion, just earlier this week in fact. He will like the next update - one of his suggestions is implemented in it.

This plane has been sitting on my "finish someday" workbench for over 3 years now. I think it's about time to get back into it. My nephew Josh started asking me electric C/L questions this morning so he can do them with his son, and that got me moving again. Let's see how long it lasts.

So today I installed the bellcrank and leadouts so I can complete the wing sheeting.

When I saw this thread I had a sudden urge to build another Kenhi Bobcat CL stunt trainer like I crashed after a 1/2 circle flight in the late 40's. It had a Christmas present Fox .29 in the nose and I had a red plastic U-Reely handle. Nobody told me to hold my wrist steady and to raise and lower the handle as needed to keep plane on the level. At 81, with bad knees, I might get dizzy and fall down and get wound up in control lines but learning to fly electric powered CL would be fun. Link show ad for Kenhi CL Models.

Here's a link for RSM Distribution, the make a lot of model kits and supply everything needed for ECL.

The Bobcat is a nice looking plane. Brodak is another big source for C/L products. I have one of their Zeros here that was started by a friend. It wouldn't take much to finish it up. Maybe once I get this done I'll think about it.

With RC, most of us basically fly in circles. Can't roll a CL model though. Maybe I could build a Bobcat and fly it by RC with a dummy Fox .29 cylinder and have it convertible to CL.

Just read that Mr Brodak has passed away, he will be sorely missed by many, not just hobbyists. Hope the family keeps the hobby business going.

I wouldn't be so sure of that...
Mine will roll according to where I put it on the 70 ft. radius half hemisphere....


And yes it's electric... Used it at the 2016 WCh.
Now that I need to replace my batteries, I can't get any at all that: are fitting, not too heavy and have enough capacity.
In 4 years' time, new batteries seem to have become obese with ~ 20% weight gain...

If all you'd want is flying in circles that would probably do. For anything else CL, converted RC models are bad news in general.
Take good care and stay on your feet! Fox .35 was my first 'big'engine:

You must have fed them too many electrons

I disagree. Below are videos of 3 of my originally C/L planes. The UMX-sized model is a Walt Musciano design from 1959 for Cox engines, the Stunt Trainer. It is the same size as the original. The changes made to it are replacing the flat sheet wing with built-up.

The second video is that same design scaled up to .25 size. The changes to it are lengthened nose moment (1"), lengthened tail moment (2.5"), and increase vertical stab area. All minor changes.

As you can see in the videos, both perform quite well in RC. I have also done a 1:1 of Goldberg Li'l Satan which only has equal wing panels (important!) and a larger vertical area. Yup, it's a handful!

Plans for all three are available on Outerzone. Kits for all three are available from Manzano Laser.
