No problem, the builds are coming along very nicely. I'd be interested in seeing what the finished weight is on that S1-A.

My original 50's Sterling S1 is a fat 34oz!

I put the first coat of white dope on the .35 size RM, so I won't bring it in the house around my wife (pictures later). The white really shows the problems with my building. Finished the little coroplast BRM and test flew it. Three one minute flights about prefect of the drawing board. It needs a larger motor to stunt I think, but should work well for training at the Ringmaster Flyathon. I'll bring it to the fun fly in Portland tomorrow.

Sorry for the electric guys, it just makes a great trainer. Then we hit with the gasers!

nice electric!

Here's the Ringmasters I've been working on for the last month or so. They all should be ready for the Ringmaster Flyathon next weekend. I now have the Beginner, Baby, Jr., Brodak S-1, oh and the coroplast electric. With any luck I'll get the Micro do too.

What a handsome group!

Make sure you build the RM 1000. It's an animal!!!!

How well did the Jr. Balance out?

The Jr. flies really well. It has an OS .15 FP for an engine. I've been joking around about entering beginner stunt with it, it will do the whole pattern if I could. I don't think there's anything it can't do. Now me, that's a different story. Next year I'd like to build the Bipe series.

**Cribbs74** Sun Sep 29, 2013 10:24 pm

I have only seen a couple Jr's fly one of them had a .15 FP like yours. It pulled like a freight train, yet it was super nose heavy. I wonder how one would do with a TD .09 up front.

I haven't thought about it for awhile, but I remember it being right on the CG. It is a Pat King model though, maybe that makes a difference. It was a great build, I-beam contsruction and everything fit very nice. The little plane really grooves around the circle, like it's on rails. My son flew it this summer and he hasn't stop demanding I give it to him.

Nice electric. You running a timer or rc throttle? I'd like to see more pictures, when you get a chance.

duke.johnson Mon Sep 30, 2013 10:45 am

I'm running a timmer, you can see it next to the bellcrank. Some guys run a RC throttle for the trainers, it gives them the chance to cut the engine if there's trouble or slow it down if it's to fast for the beginner. What would you like pictures of, I'll have the son take them. I have plans for an Electric Jr Ringmaster someday. I'd also like to build an Electric Akromaster.

Does the timer provide protection in-case of a crash and not overload the circuit?

duke.johnson Mon Sep 30, 2013 11:17 am

I'm not sure, I'm not the best guy to ask about electric set ups. If crashed and the motor is stopped early, you hear a short buzzing noise then the power shuts off. So I would guess the answer is yes. It's an E-Flite timer and you can adjust the RPM's and run time (one min., two min.,three minutes.) It''s cheap and you don't have to have a programmer and you can get it just about everywhere. You can change the RPM's while the motor is running too.

I'm an electric guy lol!

Don't mind me... but that motor seems HUGE for what you need. What size is it?

WingingIt74 Mon Sep 30, 2013 11:33 am

I'd also run a prop saver on there, especially for a trainer.

Here's what I'd have in mind:

This set up was on another trainer this summer. It's 1500Kv and it will not stunt, it just goes round and round. But that's all I wanted it to do as a trainer. The other plane was the ET-1 trainer off the Stunt hanger forum. It was a better trainer, but I wanted a coroplast trainer for the Ringmaster flyathon. So I cut a Beginner RM out of coroplast.

WingingIt74 Mon Sep 30, 2013 12:06 pm

Looks like a Turnigy motor, any idea the model number?

duke.johnson Mon Sep 30, 2013 1:55 pm

I believe it was a E-max FC28-22 1500Kv.

WingingIt74 Mon Sep 30, 2013 1:57 pm

like this one?

No. Sorry, I gave you the wrong number. It's a FC 28-12. The FC 28-22 is the one I wanted, but they were not in stock in the USA.
