.15 size RC airplane engine

would y'all please recommend a .15 RC airplane engine?
i found a set of sig tri-star plans i can build from, and that's the
recommended size engine... and of course it's the size i don't have. ;-)

You could go to

and buy a Cox .15. They are one of the hottest .15's ever made.

The nice folks over at

not only stock the excellent Thunder Tiger GP-15 .15 2-stroke motor, but they have good availability on spare parts as well:

I always try to support my local hobby stores, but they don't carry very much from Thunder Tiger. I've ordered several things from

in the past, and always been happy with the service and value. They even tracked down a particular replacement motor mount for me from a favorite old ARF of mine and added it their catalog at my request.
Thunder Tiger makes great stuff, and I'm really glad I've got a good source to find it!

The TT .15 that Ed recommends is what I recommend. It is light, no ball bearings to hassle with and it runs great.
I bought two of these and two plain bearing Enya .15s a while back when Sheldon's Hobbies was selling out their Enya engines.

I like TT GPs, too.
But I'd recommend a .25 GP for your plane.
Or a ball-bearing .19.
A little extra power never hurt anybody.
I had a TT .25 in a SIG Wonder. It was a very nice combo. The mid-air that took its life wasn't the fault of the engine.
Prior to the .25 GP, I had used a Magnum .15. Even when it was working right, it wasn't as much fun to fly as with the .25.
Yes, weight and wing loading went up. I also had rudders on the thing, so that added another couple of ounces. It was nothing like the 50 oz. electric version that I read about being flown successfully.
YMMV.

I've had mixed luck with Magnums in general, but I've had a few of the .15XLs and they've all performed great.

No. If you scale up the plane, then it's a candidate for a TT .40 GP or OS .40 FP or a .32 or .36. :o)

Obvious choice would be the OS LA 15 for about $60. Another one I like (I have 2) is the Norvel BigMig 15 also for $60.

I like the little OS, but the price is ridiculous.
I'll stick with the $44 and change TT .15. Not to mention the fact that the OS LA series engines are the ugliest engines in existence, right next to Saito engines.

I used a Magnum .15 on the Tri-Star. Need hi nitro content fuel. I used some COX fuel I had around. I forget the size prop I put on it.
The Tri-Star is not high performance, so you really do not need a hotter engine.

| How about a clean, hardly run K&B Veco .19 Series 71? It will blow | the socks of any .15 available today.
Perhaps, but where would one get such an engine? :) (ebay? ick.)

Personally, for a 0.15 sized plane, I'd probably just go electric. But that's just me.

Light, cheap, durable (plain bearing), forgiving.
I went from a Magnum .15 XLS to a TT .25 GP in a Sig Wonder. I was very happy with the results.

There's alot of good info here for finding .15 engines, but what if you
in the exact opposite situation? I have an O.S. 15 LA and am trying t find a good kit to put it in. I was considering the HOB Spacewalker bu I'm not 100% sold on it. Anybody know of any good kits/plans/ARF's fo the .15? What about electric to glow conversions

Check out the Mini Fledgling (scroll down) Built light, a .15 should haul it OK. They're fine fliers! Electric to glow conversions may need to be beefed up due to the added vibration of a glow engine.

The Thunder Tiger Dragonfly .15 ARF might be a fun choice:

It's listed in the trainer section, but by most accounts it's fast and aerobatic. It flies more like a stik than a trainer.
