Re: Engine running Very creative Merv! The exhaust fumes get reburned in the woodstove. Green heat for sure

Re: Engine running I run them in the basement in the winter. I use the outside aluminum sheath off 1/2" BX electrical cable into the wood stove. Very little exhaust smell and quite quiet too! |

Re: Engine running Kevin Your engine hooked up to the water bucket will surprise you, no noise, just the prop wirrr. |

Yeah, I imagine it’s a cost thing. In all fairness I also think all engines should come with a built-in electric start! One can dream… 🙂 (which reminds me - what happened to EME?) Frank, thanks for that info. I suppose a short run can’t be any noisier than a gas weed whacker, and we get plenty of that around here. If I have to do a longer run for some reason I’ll try the bucket. I’m lucky where I am: quiet area, good neighbours. I don’t want to be the one to spoil it! |

Re: Engine running Kevin I think cost would be the greatest barrier to factory break in . Some of my more expensive engine like the Valach & kolm engines have hours of factory break in before they are sent to you ,but your paying top dollar for that extra service. cheers |

Re: Engine running Frank, if you are running it indoors, then I suppose noise is not an issue other than the boss .complaining. I watched a video of a guy running a generator outside and he experimented a lot. What he came up with was a piece of drywall folded over the generator like a tent. The air passed through for cooling and the sound was absorbed or reflected down into the ground. It made a big difference. I know you want to keep warm when starting your diesel stinkers but others may want to keep that in mind. I have not run any motors yet at the new house. They are not very nice people here so I have refrained from it, but have scared up quite a few planes and motors over the last year that I have repaired and want to test soon. I think I will just open the garage door after the motor is running. Our flying field does not allow us to break in motors at the field. Good call there. I think an exhaust vent directly behind your test stand going outside would be enough. Maybe a deflector to direct the noise into the ground may keep the noise down? |

Re: Engine running Kevin: Seems to me the Saito engines require a longer break in time. At the factory it's all about time I suppose. But when properly run in they run great. Running into a bucket I find is adequate to just put some time on it and verify it does run. I would set the needles to factory spec, get it warm, give it a few short throttle jabs and then let it settle in at a high idle. Factory specs and instructions are your friend as not all engines are the same. |

Absorbing all the info, I think! 🙂 You guys touched on a number of points. I recall reading the break-in procedure for a Saito gasser a while back and wondering for the nth time why engines aren’t broke-in at the factory. I’ve being doing the break-ins in the air; mind you that amounts to a pair of DLE20s so far. The only reason I’d want to run an engine at home is to ensure it actually runs, and make any adjustments needed to get it running reliably on the ground. Sounds like the water bucket trick may not be much help in my case, especially since I’m only using small gassers. |

Re: Engine running Quote:
Testing on the ground has little to do with how the plane will perform in the air anyway and seeing as you can't go full throttle on a new engine you would do better to do some research on the many know setups and just use a know setup , fly it and make adjustments as necessary to improve in flight performance as the engine breaks in .. I do all my break-in in the air now but that does not help some guy that want's to make sure his engine runs when living in a quiet neighborhood, or actually wants to follow the manual without running the engine at the field for 3 hrs . All my Valach engines require 3 hrs as does 3w ,saito has very specific break in, OS & Ys the same . Eme Yep Dle ,Dla , Zdz . GP . even My Kolm calls for a break in period.. Most new engines are so stable out of the box that you can break-in in the air but break-in is still very much needed for best performance, the engines setup does change as the engine breaks in .. cheers ... |
