0.010 and 0.020 CL or R/C Kit suggestions?
I reciently came by a once in a lifetime purchase (for me anyway) from a nice gent mid Canada. Am now the owner of a 0.010 and 0.020 teedee.
Seeking to bend the forums ear on some kit suggestions? Hoping to find something currently produced or plans. CL or r/c. Also entertaining a rtr foam park flyer, just slapping a Cox on with some cg adjusting. Considering a electric mini ugly stick as well. I need to go trough some of the threads on here as well so much good info.
Is the plastic tank any good on these in terms of reliability, don't mind fiddling but not all day long.
Really looking forward to cleaning these up and getting them ripping again.

Re: 0.010 and 0.020 CL or R/C Kit suggestions?
Such a nice find.
To my mind, foam and nitro don't go together but some have made it work for more than just a few flights. That said there was a member of my Florida club that had a foam airplane with an OS something on it and flew the daylights out of it. Towards the end it was more fiberglass and epoxy than anythng else. I love the Ugly Sticks, kit or scratch one out would be my suggestion.

Hello, congratulations on the purchase.
Cox engines are amazing, my favorite is the .020 Tee Dee.
There are many cute projects to do yourself.
I share some ideas here:
P-51 Mustang
AMA PT
You can reduce the plane you want, you can modify the structure and you can make the model of your dreams, just focus and you will achieve it.

Thanks for the feedback appreciated it. Beautiful birds thanks for sharing.
Right now I'm thinking of scaling down my skyray 35 plans.

Re: 0.010 and 0.020 CL or R/C Kit suggestions?
In addition to the models suggested by others, I would recommend, for an RC plane, the Sharkface, that was available on ebay a few years ago, and though designed primarily for a 020 engine, my 010 Tee Dee pulls it with authority.

I prepared its bulkhead with mounting screw patterns meeting the 010 an 020 Tee Dee-s both, for the plane's versatility. The holes at the bottom were designed as lead-outs for the fuel line and filling line, but made these lines rather vulnerable at landing without a landing gear, so I finally led the lines out on the fuselage sides.

Or, you may want to build your own RC plane like I did, see my Lil' SpeeDee together with the Sharkface:

Today this is my go-to plane if I want to fly anything in the 010 league
I see the exhaust port orientation of your 010 is sideways, but the ports on the 020 may be orientated near-parallel with the crankshaft. In such a position the 020-s and 010-s too are prone to self destruction by their hot flue gases melting the red delrin tank. This is especially true with 30% nitro in the fuel and flying on a hot day...been there, seen that, done that...
As a remedy I apply a piece of aluminum shield cut from a beer can and tuck its tabs between the bulkhead and tank such that the shield overhangs the tank where it is hit by the hot gases. The thin air gap - constantly flushed by the propeller blast - between the shield and the tank will prevent the extreme heat from damaging the tank.


I could also give advise on a larger 020 application like my Roaring 20 that I power with a 020 in RC service...a real fun, antique design...too bad its kits are all gone from the market, but Outerzone may still offer the plans..
Good luck with these engines, they are the ultimate COX fun to play with !!!

Re: 0.010 and 0.020 CL or R/C Kit suggestions?
Oh wow thanks for the replies. Those are some really fun looking models!
The Dimond wing is cool!!! I was reading an older (for this young buck), aero modeling magazine from the 1950s it spoke to the different options for compensating for line weight, and the Differential lift that occurs between the faster airflow out wing vs the inboard one. It had a clever statement that noted, tip weight, rudder offset, engine offset are options to tune your model, however use of all at once will yield poor results. Or something to that effect.
That combat wing sure looks exciting. Man I'll need to build some of all these to be happy now lol.
To get started I ordered this kit off ebay, couldn't say know for the price. I think an 0.020 will work, we shall see. It's called the r03-stik
