|Thread: Adding Oil|
No problem. I now know what I want to do. Thanks to you all.
I know that a gallon of castor based fuel would not cost me a lot and had considered it. But I don't really want to throw the 4 litres I have away if it's perfectly useable. I'm not at all tight or penny-pinching, but I just thought that with a little more oil it would be good to go. Thanks for you posting.
Thanks for your posting which I find interesting.
From what I've read, and from what I'm reading from the posts, the engines designed years ago were made from different materials to what they are currently and require different sorts of lubricants to keep them healthy. There seems to be lots of strong opinions out there that seem to contradict each other so it's difficult to decipher which way the pendulum swings. I think there is probably a lot of truth in both sides of the argument for different reasons. But I think that I have enough information now to know what I want to do.
My goodness. I do seem to have opened a can of worms here. I'd no idea that I would receive so many replies (which is good) from what I thought was a simple question. It is what the forum is about though, so I thank you all for your experiences and your valuable information.
Thanks for the post. I am very much okay with the mechanics of engines but very weak on fuel preparations. I know all about castor varnish from all my other engines. I am only going by manufacturers recommendations which I thought was a good place to start. Your experience with purely synthetics is valuable and might be a consideration for me in the future. Thank you for that.
Thank you for that. I have just ordered a litre from Wheelspin Models a few moments ago but thank you anyway.
Yes, I think that's probably the answer.
Thanks for all your valued replies.
The engine is run in and runs very well. I just don't want to ruin it by operating it with the wrong mix.
Have you any idea where would I obtain a small amount of suitable castor oil to add to the mix?
The fuel is reasonably fresh (this year). In 1973 (approx.) I purchased the engine but it only did a couple of 5 minute flights.The two years represents the time it took me to learn to fly in 1994, plus about 12 months afterwards. It's not been used since until about two weeks ago when I re-joined a club. It's now had 4 flights in the last couple of weeks or so.

The engine in question is an Enya 15-III of about 1973 vintage when I purchased it new. It's in good condition and has had about 2 years in total run time. The reason for the request comes from the original instructions which states 20% castor oil. I understand that the engine has a steel piston and liner which is not the same as the more modern engines. I know that models do get very gluey with this amount of oil. I just want to be fair to the engine.
I have about 4 litres of fuel which consists of:-
9% synthetic oil
6% castor oil
I wish to increase the total oil content from 15% to 20%
What sort of oil can I add to the mix to increase the oil content?
|Thread: Covering advice please|
Thanks John. I was amazed just how much work was needed to bring it back into flying condition.
That's a good tip. Thanks for that. Model now covered.
Yes indeed. It's an Enya 15-III. I purchased it about the same time as the kit in the early 70's. The engine has been completely stripped, cleaned and reassembled. It ran very well indeed on my test stand so hopefully it will be okay.
Just an update. My Mercury Galahad repaired/refurbed and final covered. Aerial still to be fixed to the fin. Thanks to you all for your tips. Now for the interesting bit...….
Good advice. Thanks John.
Managed to get some Solarfilm in the colours of my choice. I think it was the last of the stock.
The instructions from Solarfilm say to cover the fuselage (box type) top and bottom first, followed by the sides last. What is the reason for this? I would have thought bottom first, then sides, and top last.
What do you think?

It certainly looks good. Is that the solid colour film on the wings and fin, or the transparent?
Thanks for that. Perhaps Solarfilm was a bit thinner making it a bit more pliable. Just a guess.
