Sterling Plan Build Off idea?

Has anyone thought a Sterling Plan build off? It might be kind of fun and interesting to pick just one series of the convertible kit series, i.e. the A, E or K series. They would have to be built RC with at least two functions and could use E or glow power.

Any thoughts?

Restricting a build off to one "brand" of plan doesn't sound like a good idea. A builder's favorite model design might not be available in one brand of plan. Most of the old Sterling, Berkeley, Flyline, and other no-longer-produced-kit plans were intended for rubber or glow power and single-channel RC, free-flight or control line. Would the the object of the fun contest is be to convert old kits or plans to multi-channel electric powered RC, and successfully fly them by a set deadline, and have forum members vote on their favorites? Would there be any exclusions of brands that are currently in production, enlarging plans, modifying dimensions of tail feathers? The object of the contest and reasonable rules need to be agreed upon.

If one of those kits floats your boat why not enter it in scale build off 4?

Thanks E-Challenged for responding!

Maybe it's just me in my desire to rekindle that time of building my first kits. For some reason the sterling kits were some of my favorites. I was wondering what kind of interest there would be in building the old birds with new equipment and hopefully achieve better performance. (Especially those convertible kits that promised to be able to fly with everything from rubber to small RC) I know there are modelers much more skilled than I at accomplishing that feat.

The free 'flighters' often have contests that exclude all but one series or brand of models, but it may be good to include the defunct Berkeley, Scientific and Comet kits. As far as currently produced kits, there seems to a fair abundance of modelers already converting them, (Guillows to name one) but the long out-of-business brands don't seem to have as much of a following these days. It would be nice to resurrect some interest in them.

As far as enlarging the plans or modifying the dimensions? I would think keeping the dimensions adds to the challenge, except for maybe tail feathers. (Some things just don't fly that well without improved tail surface areas.)

Finally, yes, have them built and flown by a deadline and have members vote.

Thoughts?

Hey Kiwi,

I could do that, for certain, but I am wanting to stir up an interest in out of production stuff, including Sterling.

Great idea I've had on my mind forever. Gotta include the Comet kits. Just built 2 recently that turned out well and fly well. Like anything else, with enough effort you can get a good result, but they honestly were horrible kits. Given that one has to pad half the formers/notches and reconstruct the wing to scrap the awful looking X-construction, they're darn near a scratch build. They would be perfect for a competitive build-off. Got 3 Sterling kits sitting right behind the Cherokee below, waiting to be built and one coming in the mail as of today.

I'm game! Converted a few of them already. Why? Because it was a challenge!
Consider it revenge for all the ones I built as a kid that flew about 10 feet before re-kitting themselves....

Haha! I concur Glenn. I could get them to fly 10 ft if I threw them really hard.

So, here is a list of some rule ideas:

1. The defunct kit mfg that can be submitted are Comet, Berkeley, Sterling, and
Scientific.
2. The project can be built from plans or kits.
3. The plan outlines and dimensions must be followed.
-except where a larger tail surface would be required
- wing and/or horizontal stabilizer incidents need to be changed
- wingspan and fuselage length and moments can not be changed.
4. It is ok to change some of the construction techniques to improve weight and
strength. Bows for wingtips and empennage are ok.
5. It must fly via RC. Any number of channels is ok.
6. Proof that it flies by photo or video
7 Submission dead _______________
8 Final Date for completed models _______________

Anything else you guys can think of would be awesome. For me it's about sticking as close to the plans as possible, just to see if I can do it.

Joe,

If the model can be plans built, can the plans be scaled up or down?

Hey George,

The key challenge of this contest would be to use the designed dimensions and make a flyable model. So dimensions should remain except for maybe enlarged tail surfaces. Even then I think most of the kit designers enlarged them originally.

Joe,

Just had to check you know... I believe your right about the designers already drawing enlarged tail surface for the most part...

I've never had to enlarge any tailplanes with of a number of old kit designs for them to fly well. I believe a number of them are enlarged a bit, while most of the issues people have reported are probably due to improperly set CG. With some of the micro under 2' span jobs it may be a bit of an issue.

Yes, most designers took tailplane size into account. I think that most of the kits we are discussing, were designed fairly well. It just seemed the balsa wood came from oak trees. I have heard that they had to use harder balsa for die cutting.

Can anyone think of any other pertinent rules? And does anyone have a suggested start date? (I am thinking dead of winter, say like December or January)
