OS 40 FSR good compession, smooth bearings. No silencer

6Nice ASP 70 FS. Smooth bearings and good compression. Surplus to requirements.

On thinking back. There werent the regular people selling fuel at Woodspring. I managed to find this fuel on one stall and it was the only one they had. I wonder if it was not actually Pro Synth but something that was in one of their containers.

I cant agree with that. I have been running both ASP and SC engines for years without any problems.

A few months ago I was running up an ASP 70 FS on my test bed after fitting new bearings. When I went back to it a few days later I could hardly turn the needle valve. After a bit of investigation it turned out that the problem was being caused by the rubber "O" ring on the needle valve. Couldnt quite work out why and put it aside for further examination. Fast forward to a few days ago and I was running a brand new SC 61 on my test rig. When I went back to it the following day, same thing. The needle valve could hardly be turned The rubber on the needle valve had swollen. I can only assume the fuel I am using is causing the problem. The fuel is Pro Synth 2000 with 10%. I bought this at woodspring in 2024. I will stop using it and get some different fuel and fit new rubber rings and see how things go.

I was Christmas shopping with the wife and after a few hours I was getting a bit worn out so decided to take a detour. My phone went with the inevitable "where are you". I said you remember when we were first married and didnt have much money. She sajd yes I remember. I said you remember that jewelers that had that lovely diamond ring in the window that I couldnt afford at the time, she said oh, yes darling I remember. I said well I am in the pub next door.

Had it for years. When I joined the Army in the sixties there was no proper ear protection apart from a bit of wadding poked in the ears. I spent a lot of time firing the SLR rifle which was high velocity right next to the lug hole. This combined with my job running up and testing engine power packs at full RPM to check governors did the damage. It was only later on that proper ear defenders were issued for range and other work. I find that day to day it isnt that noticeable. It is when there is no backround noise that it becomes intrusive.

Just purchased one of the new SC engines. An SC 61 two stroke. Very nice, excellent casting and all round good quality. And no, I am not in the trade

My only thoughts on the National centre is that more thought should have been made as to where it would be situated. If you live in Cornwall it is a bit of a trip. Somewhere more central would have been better, and would have provided easier motorway access for a lot of people.

Just picked up lidl black Friday brochure. I notice they are selling a Sky super performance stunt jet. Flies up to 35mph, barrel rolls, loops etc. I wonder how many people buying theese will bother registering with the CAA and afixing a registration number.

Not a lot of help with a plan, but the post reminded me of my own CFI. It was my first low winger after progressing from my Veron super Robot. I was a member of the RAF Wildenrath club around 1980. It was a great little model to progress with.

Have to do a bit of disassembly to get the tank out which I will do. At present it sits level with the carb , but there could be another issue. if after doing that it is still the same I will go electric. I have two other models both have SC 70 fs engines one is side mounted and the other at 125 degrees.They both run fine

I have posted before on my problem . Basically I have an SC 70 FS mounted sideways in a model, the engine runs at full chat but will not idle. It hunts and cuts out. When I mount it on my test stand it runs and idles perfectly. I changed the plug. Bought new fuel still the same. I removed the engine and fitted an OS 70 surpass. No difference. I came to the conclusion that the fuel tank may be too far back. A very kind reader to this forum sent me a perry pump to try but it made no difference. My plan was to convert it to electric this winter. I just wondered if an engine with a pump might help. I know OS do pumped 90's but that would be too big.

I am thinking of buying an OS 70 ultimate to help with fuel supply issues on one of my models. I believe that this engine pumps pressure to the fuel tank to help with fuel delivery. I read of several reports that there have been issues with this engine and its fuel system not performing very well and going out of tune after being set up and cutting out on idle. Does anyone have experience of this engine and its performance.

Yes I know that but I have a problem, the problem is that the Achievement scheme was meant to voluntary. I would be quite willing to go and fly in front of their club members and let them decide if I am safe to fly now, not as I was when I took an A 20 odd years ago..
