Default Plane for Cox .020 TD.

Recently acquired a used Cox .020 TD. What is a good plane for it? I have seen the kits on BMJR and Select Hobbies. But seems most are either old timer free flights that would have to be modified for R/C or electric models that may or may not be easy to convert. Thinking of a sport model with aileron and elevator and maybe rudder as well. Though an old free flight conversion might be interesting if it will thermal well after climb. Also I do not have any radio gear that small so servo and battery recommendations would also be helpful.

I have experience with rubber band models, and 1/2A CL, and 40 up RC, but no small RC experience, other that a small electric model that fried its battery after a while.

I'm interested in the responses you get. I have been thinking it woud be fun to try a Cox .020. Is your engine throttled?

If it is throttled, it would have a throttle ring which is more of an on off switch really at about a mm it will idle, at 2-3 mm it is wide open... the BMJR Dakota is a cool little bipe...Rog

The Corky and really all that I have seen, that is that have plans or I have seen elsewhere seem to be for beginners. The only thing I have seen other than the BMJR .020 sized old time replicas is the .020 size Ugly Stick of which Ihave seen a couple of versions. So I guess I am interested in two ends of the spectrem, but both high performance in there own way. Either high performance endurance, or high performance aerobatics.

Default RE: Plane for Cox .020 TD.

Seeing nothing so far offered seems to meet Sport Pilots requirements-I suggest you go trawling in the MB or MAN archives for the 80's-Bill Cannon-the 'Cannon R/C' guy had two designs published for the G-Mark 03 and 061 engines he distributed in the USA-and of course he sold the micro R/C gear to go with them. My memory is a bit vague on detail-but they may even have been the same design at two different sizes.
As I recall it was a low wing full house 4-channel aerobatic design-which should satisfy sport pilots need for performance. The G-Mark 03 Humming Bird engine was slightly larger in size and displacement that the TD 020-but of similar power (the TD would probably have a slight edge!)
Built light-and with modern gear, this should perform well.............

I'm only about a week away from departing for the FF World champs, so have no intention of trawling through dozens of back issues of MB or MAN to find the specific article and plan. My gut instinct is that it was in Model Builder not MAN-but I could be wrong. Someone here will recall the name of the design, and the appropriate issue. then its over to Sport Pilot if he likes what he sees. I don't know what the current status of the MB plans service is-Bill Northrop died a couple of years back. I'd just be inclined to scan the plan from the mag and have it enlarged by a copy shop to the correct size.

Another option would be any of the Ace R/C 1/2A pattern ships scaled down to about 30", or the 'Eyelash' ditto (which was a MAN plan)

Fortunately-a google search under 'Bill Cannon' means I don't have to-the design mentioned above whose name I could not recall is the Griffin III and Griffin VI-it was published in Dec 1982 Model Builder, in two versions-one for .03 and one for 06-28" and 36" respectively............and better still, you can find the plan in downloadable form at www.outerzone.co.uk and I happen to have that issue of MB and can scan the article if needs be

If you're competing, best of luck to you.

Scaling down will give you a lot more choices for quick or more aerobatic planes. Here are a few more plan sets. On the GLH, don't bother with wheels - just leave the bottom of the fuselage flat.

Yes I'm on the NZ F1A team-and good luck is always welcome! [hopefully I had my full ration of bad luck last time- a serious hamstring injury in practice the day before F1A. Its very hard towing a glider when all you can do is hobble!] The prevailing feeling this time is that the venue-Moncontour is in western France-south of Brittany-will be hot and windy-not the conditions I'm entirely comfortable with....

The planes I recommended are available in kit to ARF form, and reasonably priced. Call John @ 586 773 7069 and tell him what you are looking for-his kits all fly really well and are definitely proven.. Most are older than me! JMG specializes in scale-ish looking pattern and pylon planes that have glass fuses and foam core wings. Some wings are built up, and he does sheet them if you want him to.

Default RE: Plane for Cox .020 TD.

OK, plans are great, but really I hate to cut out parts, though not bad for a small plane. I had expected someone to suggest an electric to glow conversion. The fact that most electric kits cost way more than they should (even when they don't include the motor)is probably the reason. But I have found one that seems to fit the bill, there is a electic kit without motor from Hobby King that looks to be a long nose version of the LA stick. One could easily shorten the nose and attach a Cox .020 to it. And there is even a wood only kit to build another for after the crash!

Anyone try this?

Sorry forgot the link before.

That looks fun. 23 inch wingspan. A TD should fly it well. You might have to use slightly bigger servos than the ones suggested because of the IC vibration. But for $27, its pretty cool.
