Title: Pat King micro Ringmaster twin
Post by: Dave Nyce on December 12, 2024, 08:25:08 AM

Finished building a micro Ringmaster twin kit by Pat King. It has two Cox Tee Dee .010 engines. Very nice kit.
I added a wingtip weight box. Put some lead inside the nose wheel to balance fore/aft.
I planked one extra bay in the wing to make covering easier.
Pat King has lots of control line kits and plans available.

I'm a sucker for twins. This one is just too cute!
Great job. Please post links to flight vids.

I have the little Pat King single engine micro Ringmaster.  As much "fun" as it is to start one .010, hard to imagine the "joy" of getting two of them going.

I don't really have any trouble starting mine. I have six TeeDee .010 engines.  I made a small electric starter for them. Also works on my .020 engines.

Mr. Dave,
I'd like to see the starter. What did you use for the starter cone and holder?

I bought a motor, a LiPo battery, and a high current micro switch on Amazon. Made depressions into a piece of wood for the motor and battery. Drilled into a piece of aluminum rod for the motor shaft at one end and a piece of rubber tube at the other end.

And what fuel/duration can you get with them? What length and line size? Lap time?

I use sig champion 25 fuel of which I still have a few quarts. 10 pound test yellow braided line, 15 to 20 ft long, depending on the model. But I haven't flown the twin yet. Maybe a little longer line for the twin. With .010 integral tank, runs about 1 minute. But I use external tank on most, for run time 2 to 3 minutes.

Thanks Dave,
I'm just wondering if someone can get an official pattern flight with 2 010 engines.  I just got a pair and I'm wondering if it'll be worth the effort.

I had a 1/2A Snapper with a .010 and it could do a complete pattern. I have witnesses who saw it. 🤠
