My last two new heli engines have been an O.S.70 and an O.S.50SHX,
both of which have blown holes in the piston.The 70 originally had the mark 1 piston, this was replaced with the mark 3 piston under warranty
and has been no more problem.The 50 was also repaired under warranty and I guess that I was just unlucky that it failed.In the past I have had numerous O.S. engines, probably over twenty if I include aero
engines, but I would have to think twice before I buy another O.S. heli engine.On the other hand, I purchased my West 50 second hand and would definately have another one.

I'm just going by what I was told at the hobby store. I was more interested in building up my new Raptor 30 today, so I didn't go into any further. At some point I'm going to upgrade the Rappy to a 50, so I'll just toss the TT39 into the Shuttle to have as a backup heli.

But, I thank you for the information!

PaulH-MA,
I'm suprised that your Enya 35 has a metric thread on its shaft, I have an Enya 30 heli engine from the late eighties and that has a 1/4 UNF thread.I thought that the 35 was a later engine.My Shuttle from the early nineties required an engine with a 1/4 UNF thread as did the Concept 30 and the Space Baron (Enforcer).I can't think of a 30 size heli that required an engine with anything other than a 1/4 UNF threaded engine , are you sure that your Enya has a metric thread?

I dont everyone is forgetting about the west engines, however even you yourself have mentioned in a previous post it is not a set and forget engine, constant changes everytime you go out flying.
I have a west 36 in my rappy 30, previous to that i had a tt39. Hands down the west has got more power, but the tt was a whole easier to work with.
The other thing is the fuel - expensive, and you have to use it to maintain warranty, and nobody will tell us what is the oil content.
Dont get me wrong i love my West 36, I also a WEst50v1, again fantastic engine, but there are easier engines out there.

My West 50 is definately a set and forget engine.I haven't had to touch the carb since I first tuned it in (it was a second hand example which had already been run in).

Am I hearing right - you need to use Weston brand fuel to maintain their warranty on engines they sell?

I have heard that you have to use Westons own fuel, but having had problems with it in O.S. and Y.S. engines in the past, I don't use it.Prosynth has a very low oil content and I would rather not have the warranty and use fuel with more oil.A friend had his West 50 rebuilt under warranty when it seized up but he said that he would never use Prosynth again, I think the risk of another emergengy auto bothered him.I have also been told that West engines only run properly on Prosynth fuel, but I use a fuel with a castor/synthetic mix of 20% oil without problem.

If you do not the Weston recommended fuel you will get a 1 year warranty, running ProSynth you get 2 years.
You do need to be more careful as the oil content is lower, so the tell tale smoke stream is not visible, but the engine is supposed run cooler as well.

littleman time for you to step in here - as a Weston rep what do you advise...

fuel
i use cp 15 and i find that it is a better running cheaper fuel and i dont beleive that you will have to worry about the warrenty at all. i agree that the prosynth has to little oil, i had the same problem. i just use the cp and have no problems.

What is the lube content and make up of Prosynth? What Nitro levels are available? Is Prosynth sold here in the US?

I don't know the oil content by volume, Weston U.K. will not tell you.However, a fellow club member is a chemist and he checked some Prosynth 10 for me and concluded that it had about 17% oil by weight.So by volume I would guess that the oil content cannot be more than 13% if that.As for nitro content, I have checked their web site and they list straight fuel right up to 50% nitro.If the oil content is different with different nitro content or if the fuel is available in the U.S. I don't know.
