We do have nastier stuff here at work, bad enough that I'm not allowed to take it out of the resin room where we keep all are paints and adhesives and any other sort of harsh chemicals, I'm not even sure what it is I just know we have 2 different types that can't leave that room, I have never understood why we even have them when we can't hardly use it.
Anyways 1QwkSport2.5r after you strip your 25La let me know how it goes, I have another LA that may get the same treatment

I may have mentioned it before, but the control line guys have been using the LA .25 specifically, and using any mods. One was even a rear exhaust. http://flyinglines.org/kb.frankenstein.html There are a few articles about them there. I know the smaller FP .15 was slower than the LA and it had the extra port. I tried a turbo head in an LA .25, it was only slightly better. The LA .15 was a bit better, but not nearly as much as the ASP .15 improvement.

Some literature I came across. http://www.flyinglines.org/kb.la25rework.html

Now you have some ideas to get going on. We are not allowed to modify our LA .25 racers at all. Out west there, it is encouraged. I think I have a plane that is pretty much legal for that class. No paved circle to test it nearby though. I think my old Supertiger .21 car motor went about 90 mph in it, back in the 1990s. Maybe this LA might be around there? I would not paint it, it would not let the heat out unless it is a metallic paint IMHO.

25 size ugly stik ! theres not much difference in weight between a 25 and a LA46 .Something around a 1100 mm or 1200mm w.s. Or a smallish size 46 arf . Whats your experience level ? I have a OS55 on a scanner and it zooms aroun ok or even a sonic are good value . Maybe if u want a rokect keep that LA for something else . Cheers

I would say I'm an intermediate to advanced pilot, well probably more intermediate since I've had a few years away, I have a Eflite edge 540bp profile that I fly now and again but that's all the last few years.
Before that I was flying every Sunday with my friends, if you look in my Hangar here on rcu you can see what I've flown, there's a couple birds in there waiting for a maiden flight still.

Those links gave me some numbers to use and an idea of performance to expect... But there's things I intend to do that they didn't, so we'll see if it works or not.
Now os to get the sub-zero weather to blow away so I can get to work... Yuck. It was -4F during the day yesterday and -14F overnight. Ish.

What I understand is that using ringless piston/tapered bore configurations, the metallurgy has to be just right to maintain piston seal at operating temperature. The proper alloys required to facilitate this are more expensive and as such probably why most engines are ringed in those larger displacements. I didn't mean to say nobody use ringless pistons in those bigger engines, it's just very uncommon to see it. I don't know what would be more expensive - properly plating an aluminum liner with chrome or using the right brass alloy and piston alloy to use a true ABC setup.
I am very much a fan of my AAC engines. I have an AAC Enya and two AAC Jetts. The liners weigh a fraction of an equal sized brass liner.

Deal, depends on what you mean by "authority", but to me anything in the 3 to 4 lb range will do very well with an LA 46.
If you wish for an OS 15AX, why not try the new Enya 15CX? Scroll down, then check out the exchange rate...$73 bucks plus shipping.

Those new Enya's really are beautiful motors, actually I think the 15cx would fill my needs perfectly, and the price is definitely better then the old OS 15cvx or whatever it was called, they wanted $120 plus if memory serves me.

Well I have two of the OS 11AX engines on the way Hopefully here in two weeks. depends on customs. Just have no clue why I spent that much money on two engines. I am a sucker if it says limited edition.
I am glad enya is still making engines i will have to order some with tax money

Well since collectors engines I will only open one box to ogle at and the other will be sealed in case i decide to sell it one day. I did look at doing gold plating on my own and for around 3,000 bucks I could get the right equipment to do aluminum parts and could do other parts but not sure i want to go down that road. I was never a jewelry kind of guy but the saito or SO 30 FS that came out I was hooked lol I wish the 11AX was much lower in price though as i am sure they would a bunch of them. Even if the price was 150 people would buy them.
