Hi, I just wanted to poll your opinions on oils.
My Gassers are running 50 to 1 mix using fully synthetic oil (castrol tts) and pump gas.
I like the fact that they are much cleaner than nitro birds, but mine seem to deposit oil residue on the blades, tail-boom and frame.
These oily "splashes" are easily removed with a little gas on a cloth, but they are annoying.

Is my mix too oil rich?

Is it normal that synthetic oils do not burn like mineral types?

I suppose what I am asking is is this Normal?.

It is normal when runing with full synthetic oil, that you will get oil "splashes" at 50 to 1, on your helli. what you could do is go with a bit less oil like 60 to 1 or go with a semi-synthetic oil at 40 to 1 or mabey 50 to 1, I run 40 to 1 semi-synthetic oil and get on! oil "splashes" on my helli, give it a try and you will see.

P.S. sorry for the spelling or the grammar I am dyslexic!

I was getting the same mess with the Amsoil Sabre and found it to be very dirty. I switched to the Stihl Ultra HP and it is super clean. The Ultra HP has also gotten some awesome reviews.

Do a search on Flyinggiants.com and search Stihl oil. Also go to the Stihl website for more detailed oil information. As far as detailed information on helicopter usage, I don't think there is any. I know from experience what I like and works for me Someone else may find other brands works better for them.

UK oil types
Yes you can source almost anyting with effort.. but the castrol TT and TTS are easily bought in any Halfords.
A UK tuner advised me to buy Castrol XR77(harder to source)... which I have yet to try...just done the mineral gallon on the new engine..
BUT I looked up the Castrol Oil company's advisories and data sheets on this oil.. Designed as a racing two stroke and they make the point that it is designed to make a deposit to aid tuning.

The point being that if you do end up with a bit of cr@p coming out of the uffler and splashing on stuff .. it doesn't necessarily mean its a bad oil or too rich a mix of oil...it just means you have heli in the way of your exhaust flow...

..which you could probbaly solve either by simply adding a plumbers right angle fitting to the tailpipe or some other deflector or pretreating the bits that get splashed to make it easy to clean?

Oil splashes

Thanks for the info, guys.
I will experiment and try other brands etc.
As for deflecting the exhaust, the guys at my field do tell me that my heli's will fly the other way up!!! I suppose inverted and backwards flying makes it worse. LOL

Thanks again, Keith

..running in with castrol TT... it's what I used on both engines before..and it is convenient to get. I then ran them both on the TTS.. and the engine replaced looked fine on that..it was the source coil that died and cost to replace copared to cost of stock engine didn't make sense to me if there might be other issues too.. so bought a modded engine
