AP .09 and the .15 engines
 

Anyone using these engines on their c/l planes?Worth using or not?Do they perform or not?Looking for some inexpensive .15 size plane engines.
thanks Jim.

I like them for the value at least. The muffler needs the outlet opened up or removed completely. Just a bit less power than an LA, which is a great motor. The Aussies use them for their 1/2A team race. This is the only one I have flying right now.

I have a .09 destined for a build I am doing. I bought new, had fun breaking it in. Fun because it gradually picks up performance, and who doesn't love being told to run it wide open to break it in. It has a good sound, and I went so far as to buy a new .15 from HobbyKing, I think it was.
Here's a good vid of a .15 on a delta wing

I don't need a lot of power for what I am doing so won't open up the exhaust tube.

For the price, you can't go wrong getting one and trying it out.

I have started a delta similar to that one for the .09 I have. Called the "Crazy Herb Cheap Delta" Everyone calls the .15 a Hornet, but really it is the Yellowjacket, the .09 is the Hornet. What other .09 or .15 is still being made now for less than $200?

I have an ASP 15 (which is actually a 12) and a couple of LA 15's. Each run only a couple of times. And a LA rc thats never been run. I would take $100.00 for all three if your interested. Plus I'll be in Phoenix in a couple of weeks if thats close to you I can deliver.

i SEE YOU HAVE JUST A VENTURI ON THE .15, WHERE DID YOU GET THE VENTURI SETUP FOR IT?

Here is my Dragoon with an AP15 - it came with the venturi off eBay (the engine that is not the venturi).

How does the plane fly with the AP15?Plenty of power?What size wing is that?

I made the venturi and needle valve assembly on mine. The needle is a 2-56 threaded rod with a taper I just ground on a sanding belt. It was stainless steel, so I could not solder it, so I had to butt nuts to keep the big washer on. There is a control line venturi available though, as a friend has one. I believe the needle assembly from the RC one threads into it. It is above the casting though, not like mine. I can not speak for Annette, but mine goes fairly fast with the thin wing. It kind of mushes around on loops, which is because of the wing being, well, a real estate sign. I have since cut the wing much smaller. It was traced from an F2D combat wing, but now is more like a Lil Satan. Still flies about the same. I have added a pic of the modified muffler, and a header I made for using http://www.rcuniverse.com/forum/atta...mentid=2148881a pipe. The muffler stinger can be unscrewed which opens it up to about 5 mm. It is a 6mm thread. I tapped it to 5/16" -32 or something and made a new stinger. I have also tried a turbo plug head which I made up. It helps about 1,500 rpm.

The Dragoon is not finished yet.

It's 37" span.
