Danny Fenton Posted August 5, 2022 Author Share Posted August 5, 2022 Alan to be honest i have no idea. I have tried to do as others have suggested, i will run it like this, if it breaks again, i will re-think. I have a 5065 Turnigy that would drop straight in....... only kidding.....

Eric Robson Posted August 5, 2022 Share Posted August 5, 2022 Small rubber bobbins, there are some on Amazon 15mm x10mm M6 screw either side. Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted August 5, 2022 Author Share Posted August 5, 2022 I tried rubber, it melted and exhaust was worse. Lets see how this is before we go hacking the front about. Cheers Danny 1 Quote Link to comment Share on other sites More sharing options...

Danny, I know these are not quite the same as your situation, but here are a couple if photos of how I added stabilising brackets to exhausts. Both are Saito engines and both are linked to the engine or the engine mount 2 Quote Link to comment Share on other sites More sharing options...

alan p Posted August 6, 2022 Share Posted August 6, 2022 Seeing as your motor mounts are integrated as part of the airframe (assuming beech rails)surprised there is that much torsional vibration. Do like David's solution though. Stick with it you will get there in the end.👍 Still think you will need a food parcel sent to the flight line to keep you going with the 6oz tank.😉 Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted August 6, 2022 Author Share Posted August 6, 2022 16 oz Alan! Yeah the vibrations were a lack of running in and massively rich low end. We will see how it behaves now. Cheers Danny Quote Link to comment Share on other sites More sharing options...
Colin Leighfield Posted August 7, 2022 Share Posted August 7, 2022 I’ve got a Saito FA82 in a Mick Reeves Fw190D9 and never had any vibration issues. I have found though that I can have problems in setting it up on the ground if I take too long over it, because it tends to overheat and that messes it up. 1 Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted August 8, 2022 Author Share Posted August 8, 2022 Hi Colin, the mixture was way to rich, there is possibly not a vibration issue any more. 1hr round trip to go run it has put me off doing any more. Was hoping to fly the Auster in the scale comp this Wednesday but havent had time to mess with it further.... i will fly my new Chippie instead. Out of interest what are the symptoms of overheating? I havent run this with the cowl on yet, what should i look out for? Cheers Danny Quote Link to comment Share on other sites More sharing options...
cymaz Posted August 8, 2022 Share Posted August 8, 2022 (edited) Suddenly stopping in mid air at an unrecoverable altitude ......and I'm not being sarcastic either. A club mate nearly wrote his Stampe off on Saturday like that. After a couple of mins after we got there it still nearly burnt your fingers.... Gradually losing power and engine speed is a good indication Edited August 8, 2022 by cymaz 1 Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted August 8, 2022 Author Share Posted August 8, 2022 Okay cheers, anybody any idea of cylinder temp, as i have a temp gun i could measure it through the cowl nose opening Cheers Danny Quote Link to comment Share on other sites More sharing options...
cymaz Posted August 8, 2022 Share Posted August 8, 2022 220F seems the general consensus on the web. I'm sure you've got the motor well baffled as I seem to remember 1 Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted August 8, 2022 Author Share Posted August 8, 2022 Yep within 1mm for the most part. Worried the baffling will work in the air but not on the ground, as Colin alludes to with his fw190. Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted August 8, 2022 Share Posted August 8, 2022 Do all of your engine setting up before you fit the cowl then its down to fine tweaks on the flying day, I'm sure you are not going to have a problem with it. 1 Quote Link to comment Share on other sites More sharing options...
cymaz Posted August 9, 2022 Share Posted August 9, 2022 If you are worried about the engine, as Ron says, also fly the maiden without the cowl. Adding nose weight to compensate the cowl weight. 1 Quote Link to comment Share on other sites More sharing options...
Colin Leighfield Posted August 9, 2022 Share Posted August 9, 2022 I think Ron and Cymaz have hit the nail on the head. When I flew this originally, the motor was pretty much right “out of the box”. Later on I decided to tinker with the settings to “improve” it, but leaving it running for too long without realising that it was overheating, lead me to set it up too rich and causing it to run evenly and cut when I throttled up for take-off. I haven’t flown it for a long time, but now that I’m flying again, probably will, because it’s a brilliant flyer. However, next time I’ll set it up with the close fitting radial cowl removed. There’s no question that the FA82 is a good motor, it has a great reputation. 1 Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted August 17, 2022 Author Share Posted August 17, 2022 Okay the final engine runs tonight have proved very successful. There was no significant vibrations and the exhaust is solid. The idle is low enough that the model doesn't creep, and there is more than enough power. Still a little smoky at full throttle, but I can live with that. Will probably only put 10oz of fuel in the 16oz tank and try that, see what's left after 5 minute flight. The more fuel the further forward the c of g More antics in the garden Next stop the maiden..... Cheers Danny 4 Quote Link to comment Share on other sites More sharing options...

alan p Posted August 18, 2022 Share Posted August 18, 2022 Other option is a nice thick (leather type) gardening glove most diy stores sell them . Will still hurt if it catches you but there is protection, better bruised than sliced!! Looking forward to a successful maiden flight👍 Quote Link to comment Share on other sites More sharing options...
