  1. Sorry Jon - didn't know. Maybe I'll post a video ?
  2. Thanks Jon. You can see it yourself down the ADMFC field ?
  3. Thanks Marty, always good to see what others are experiencing. I also dont seem to have much coming out of the breather - I have looked as its running and there is definitely the occasional drop coming through but nothing much - hopefully that's OK!
  4. Hi Jon, its in the Seagull 15cc size P47 kit. Did have a Laser 100 in it (flew lovely), but I fancied a radial for a long time and thought it would be ideal. The engine fits exactly (with cam covers just touching the cowl. Haven't flown it yet as I am not confident with the motor yet. Hopefully she will now sound as good as she looks in the air. You are right of course - keep to the instructions, but I hate the mess. I will think about it and get it running on 10% and go from there. Thanks for your in put - really helpful ?
  5. Thanks Jon - I appreciate the advice ? If you did a radial 120 I would have bought one! I have to say that all (4) the Laser engines I have are so easy to set up and use. I will probably go to 10% (might try the Laser 5...) but to be honest to Saito instructions state 20% oil by volume - so I guess I'm not using spec levels anyway. Optifuel I think is 18% - so fairly close. Do you think they recommend such a high oil content just to be safe? I know methanol doesn't lubricate like petrol - but petrol engines run hotter and are using a 25/30/50:1 mix - it seems so unnecessary with modern lubricants to run our modern CNC machined engines on high oil levels. Would anyone run a modern car on a 20W/50 oil..? Anyway - thanks again - I think I am a little happier now ?
  6. Thanks Nigel. I think coming down to 10% nitro will help. I have also noticed the fuel nipple (main needle threaded section) was slightly loose - I could move the whole assembly back and forth (discovered this while taking off the fuel pipe!) so have tightened this up but haven't run it since (raining today) so maybe that wasn't helping! I will try running it up again next week and run the higher nitro fuel through to bed it in and then maybe look at 10% fuel to try. I would like to run it on the 5% Laser fuel (that way I only have to take one lot of fuel to the field!) but I worry that its not suitable. Perhaps I should ask Jon at Laser his thoughts...?
  7. Hi Frank, do you know what the oil content is with the Prosynth? Its a good point you make regarding the nitro. Do you get a lot of unburnt residue in the exhaust? When I say a lot I mean you can see it pouring out of the exhaust! Even on full throttle its like someone is spraying cooking oil from a spray gun! Even the old 2 strokes didn't chuck out as much as this - its mad. On full throttle it goes through an 11oz tank in about four minutes flat.! It sounds great runs well (top end is a bit inconsistent) but just drinks fuel like there no tomorrow...
  8. Hi Nigel, the engine runs fine - its just the amount of exhaust waste (unburnt oil?) that is my issue. The instruction say to use 10-20% nitro and 20% oil. The Optimax 20 is only 18% oil but there is still a huge amount of exhaust waste. Just wondering if anyone out there was running the same engine but maybe on 15% oil (like Laser 5). Maybe I just need to live with it and get used to cleaning huge amounts of oil off the model again! ?
  9. Hi John, Yes tuned OK - transition is smooth and crisp (with 20% nitro not that hard), I am running with the Just Engines on board glow set up (recommended on other threads)with OS 'F' plugs. The engine runs just fine - its the amount of unburnt (looks quite clean) residue coming out of the exhausts. Its a glow, so I know there is going to be smoke and residue (I have quite a bit of experience) its just the shear amount that is surprising.... If this is the way - then so be it. But running Lasers and going from 'std' to Jon's 'Laser mix' fuel which he told me had a little less oil made a massive difference to the amount of muck coming out of the exhaust and the amount of fuel the engine consumed. The re-tune when switching was dramatic - far leaner, but all my Lasers run brilliantly without any issues (no on-board glows and regardless of fuel tank position!)
  10. Is anyone out there running their Saito R3 120 on anything less than the recommended 20% oil content? I am using Optimax 20 Super SLV which works fine - but the amount of unburnt oil coming out the exhaust is incredible! I run Laser engines (100's, 150 and 155's) which all run on the Laser 5 which is great with very little mess without any issues (I do like Lasers!). I don't want to ruin my lovely new Christmas present - but I could do without the mess. I ran a whole gallon of fuel through and the Workmate stand I used looked like I had poured a litre of cooking oil over it! Any comments/experiences would be appreciated. Cheers Phil
  11. Hi Matty, it’s a 2A 5v output and the rating on the ignition system is 600mh so hopefully it will be ok. Unfortunately I don’t have any way of testing the draw of the unit. Good point though . Thanks for the input 👍🏻
  12. Thanks Colin - that puts my mind at rest - and makes installation a lot easier! Cheers
  13. OK - thinking of using a 7.4v 2100mah Lipo. Using that with a direct feed on a FG17 and it only takes about 500mh after about an hours flying and about the same for the radio on my Seagull Moth. I was more worried if it would cause any interference?
  14. Hi All, Does anyone know if it is OK to use a UBEC for powering the receiver and servos as well as an ignition system (Saito FG14a)? I have a Dr Mad Thrust (?) 5/6v UBEC which has a switchable output for auxiliary items. I would like to use this to power the ignition system (good safety as I can use it as an engine kill) - is that OK?
  15. Posted by Brian Cooper on 28/02/2017 08:07:06: I am with the "air into the carb" solution. Engine cowls do seem to restrict the air which can reach a rear mounted carb. I had (have) two Spitfires which suffered the same symptoms as described in the original post. Both have petrol engines with rear carbs and both were cured by making a scoop which channels fresh, cold air to blow directly into the carb. . The faster the prop went - or the faster the aeroplane flew - the more air was blasted into the carb. One Spitfire is fitted with a DLE35RA. . This has a rear exhaust and when the engine is mounted inverted, the heat from the exhaust rises a very short distance to the carburettor, and this was affecting the performance. . I installed a heat shield between the silencer and the carb, and made better exiting for the heat, plus a channel to get cold air into the carb. The improvement was stunning. Problems solved. The engines are happier across the entire rev range. . . and sound very crisp at full bore. B.C. Hi Brian - I think you have a good point. I have lots to go at. Thanks for your input
