Author Topic: My first cox .15; which plane? (Read 3243 times)

John Stiles · « **on:** December 15, 2009, 09:08:05 AM »

I'm the proud owner of a used[bench run only]Medallion cox .15 and it has tons of compression. I have an idea this little engine is gonna be fast. So, being relatively new at this type, which plane/size/type would y'all experts suggest? I have the TD .09 engine, and I built this copy of an e-flight plane I built that I fly with the .09 but I'm pretty sure I'll hafta go quite a bit larger. Thanks for any suggestions

There are a lot of kits for the Medallion .15. I still have my oldest daughter's SIG Acromaster hanging on the hook. She flies it once in a while. I use 7-6 or 8-4 props.

The wing on this plane is 24" x 8".

For your first plane for that engine I would have to second Ty's choice!

Where else could you get a kit in today's market that has:
Kit Features
•Balsa Profile Fuselage
•Built-Up Balsa Wing
•Shaped Balsa Leading Edge
•Shaped Balsa Trailing Edge
•Die-Cut Plywood Doublers
•Sheet Balsa Tail Surfaces
•Molded Plastic Canopy
•Formed Wire Pushrod
•Formed Wire Landing Gear
•Silkspan Covering Material
•Building & Flying Instructions
Hardware Pack Includes
•Nylon Bellcrank
•Nylon Control Horn
•Hinges
•Bolts, Nuts, Screws etc.

All this for less than twenty five dollars? You can choose another anytime later!

For kits I would suggest the Akromaster or Flite Streak Jr. Check with SIG and Brodak for current kits.

For profiles from plans there's also the Magician 15, Jr. Satan, Shark 15, Ringmaster Jr.

For full fuselage plans there's the Jr. Nobler.

Good luck with your new engine. Glow plugs are available from Cox International (Xena & Bernie).

Jr Ringmaster.

If I could find one

Paul Smith · « **Reply #8 on:** December 15, 2009, 04:44:32 PM »

Brodak Junior Lightning Streak.

No problem getting plans and/or kits.

Dennis Adamisin · « **Reply #9 on:** December 15, 2009, 06:43:45 PM »

Brodak Jr Flite Streak or Jr Lightning Streak are both great kits and great flyers.

Another choice; the Brodak 1/2A Pathfinder - believe it or not, is virtually the same size...

Wear ear muffs. Little boogers are noisy.

I have a never run Olympic 15 that I'm debating to use. My favorite engine as a kid, which may explain why the TV is turned up so loud.

A Sig Akromaster would be a good kit. Don't bother with the flaps. I flies fine with just an elevator.

Don't worry about my ears.......they dun gone

I believe I did it to myself in the service of my country!

John Stiles · « **Reply #12 on:** December 16, 2009, 07:19:47 AM »

I'm leaning towards the flight streak....been a long time since I built one of those.

I had an Olympic 15 as a junior. My first big engine, bigger than 1/2A anyway. I wish I had gotten it later when I know better how to use it.

It's a pressure-only engine. I wasted a lot of effort trying to run it on a suction tank.

Dennis Adamisin · « **Reply #14 on:** December 16, 2009, 11:14:35 AM »

I have one of the Sportsman 15's I'd like to fly some day. Thats the plain bearing de-rated version of the Olympic. Beautiful engine - but tough to mount!

John, what do you use to cut all those nice circles and shapes in your balsa? I always seem to have troubles even with sharp blades in my zacto when going against the grain!! Nice looking little combat ship.

Different sizes of tubing serrated on the edge and twisted on the lines.

John, the Flite Streak Jr. is an excellent choice. You will find that construction of the Brodak version is different from the old Top Flite one. While Top Flite still owned the FS Jr. George Aldrich came up with the Lightnin' Streak series fot Brodak using a different empennage. When John Brodak acquired the Flite Streak series, George Aldrich worked with him so they would be EXACTLY as he designed them before George would put his name on it.

Top Flite had taken some "short cuts" that altered its flying characteristics a bit. I have built many of the TF versions but none of the Brodak versions (yet). I do have the Brodak Flite Streak kit but haven't built it.

While the FS Jr. would be great for a Tee Dee or Medallion, it may have too short a nose for an Olympic or Sportsman. I remember having to notch out a FS Jr. a bit to fit a Webra Mk-1 diesel (also rear induction).

A SIG Akromaster might be better for those because of the longer nose section.

Okay.......back to the drawing board then

Hi John

FWIW I will throw in an opinion. All of the planes listed are great planes, i believe my first choices would be the Sig Acromaster - our group has had a lot of success with those - and the 1/2A Pathfinder. I have just recently found out just how good that little plane can fly. Best of luck with what ever you choose.......

I flew the Sig Acromaster with an FP10. The Cox 15 Medallion is nice and light and would give you a good balance, but you might want ~52 foot lines. Any of the Juniors (FLite, Lightening, Ringmaster) would be a good choice too.

You might check Dee Rice and Pat Johnston (check out the "Brotherhood of the Ring) for Ring Jr. kits. I always liked that plane. I still have a Sterling Ring Jr. I call it my lead sled!

Thanks Alan, I have 52' lines, and I will certainly check
