Martin Harris - Moderator Posted March 10, 2016 Share Posted March 10, 2016 Best of luck with the maiden - just make sure those screw fastening pushrods connectors are properly tightened and loctited (and rechecked regularly). Personally, I only ever use them for throttles...z bends or clevices for me... Did you consider mounting the engine sideways and perhaps adding a dummy cylinder on the opposite side?

Martin Harris - Moderator Posted March 10, 2016 Share Posted March 10, 2016 ...and rather spookily, just 6 hours after posting the warning above, I was checking over a clubmate's new Piper Cub which had these devices on all of his servo arms. I took special care to check that I couldn't move the rods in the connectors and asked him to confirm that he'd done them up as tightly as possible. We ran the engine for a while in order to iron out some flow problems and once satisfied that all should be well for the maiden, carried it out to the strip. As per my normal practice, I did a final control check for direction and movement before taxying out - and the elevator failed to move. I stopped the engine and we took it back to the pits for examination. You're probably ahead of me by now - yes - the servo arm was moving freely up and down the pushrod...please check yours again very closely before flying (if you decide to stick with them).

Piers Bowlan Posted March 11, 2016 Share Posted March 11, 2016 Very neat build Edward, love the wheels too. On the subject of control surface clevices people sometimes slide a piece of fuel tube over them (once attached to the control horn) as a keeper, to stop them springing open in flight. Can happen, especially with an IC engine. Your workshop (man cave) is amazingly neat too! Quote Link to comment Share on other sites More sharing options...
Edward Perera Posted March 11, 2016 Author Share Posted March 11, 2016 Hi Martin, Thank you very much for your valuable advice. I will take extra precautions with the push rod fastening screws, before every flight. Already they are fitted with loctite. A couple of years back this FS 60 was fitted to a Piper J3. And it had a Dummy Cylinder. Hope you will like the pictures. I did not consider it with the Slyingsby, as the weight of the FS 60 alone was 200 g. more than what is recommended.

Edward Perera Posted March 11, 2016 Author Share Posted March 11, 2016 Hi Piers, Thank you very much for your kind comments. I have already fitted the fuel tubing sleeves on the clevices. Quote Link to comment Share on other sites More sharing options...

Edward Perera Posted March 13, 2016 Author Share Posted March 13, 2016 The Maiden Flight. Today morning the weather was fine,and I decided to do the maiden flight. It was totally a success. As there was hardly any wind, a three point landing was attempted. Quote Link to comment Share on other sites More sharing options...
Colin Leighfield Posted March 13, 2016 Share Posted March 13, 2016 What a nice aeroplane. Looking at those photos I can almost hear it chuffing along. True relaxation. Quote Link to comment Share on other sites More sharing options...
Frank Skilbeck Posted March 13, 2016 Share Posted March 13, 2016 Lovely, a video with sound would be the icing on the cake . Is the OS61 powerful enough? reason I ask is I have an old Vega 50 horizontal twin, this could be an ideal model for it. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted March 13, 2016 Share Posted March 13, 2016 Thatbis great. When I was looking at the earlier pictures I was going to say that I thought that it might need some down thrust but obviously you got that right. That dummy engine is beautiful, really looks perfect. I know just how hard they are to make. I love those wheels too. I used to have a pair of Fulton Hungerford's wheels but they were a little smaller. Nice tailwheel unit too. Quote Link to comment Share on other sites More sharing options...

I had only a few flights yesterday, and believe that the FS60 is delivering just the right amount of power. I am not familiar with the Vega 50 horizontal twin. I would love to see a picture of it, if possible, please. Quote Link to comment Share on other sites More sharing options...

Here you go, but if the OS61 was just enough I don't think the Vega 50 will cut it, it's probably slightly less powerful than the original OS40FS, thanks.

Peter Miller Posted March 14, 2016 Share Posted March 14, 2016 My own T31 M was orignally powered by the early OS 40 FS. but it needed a 40 Surpass. I did own one of the original open rocker 60s which flew a Boddington Bistormer quite well. Quote Link to comment Share on other sites More sharing options...

Hi Martin, I may have check the wheel collars as well !!!! We had to scan the landing area to find the lost wheel collar. And we found it !!!

Peter Miller Posted March 20, 2016 Share Posted March 20, 2016 I HATE wheel collars. I always bind with a little wire ans solder them. Never lost a wheel yet. You were lucky to find it. There are more bits of model scattered round our flying site and in the long grass and wheel collars would be lost even on the mown runways.

Can you give me some detail on the fuse couplings, look really good. Bas Quote Link to comment Share on other sites More sharing options...
