    I am removing my gyros and inverters for weight savings. I have Dynon and can live without the Russian stuff. Any hints? Can I just undo canon plugs and remove? Is it worth tracing wires to remove wire bundles or just leave them alone?

    Hey Rico, I have oil pan heat strips installed. They work great. Only problem is I preheated engine compartment and still blue an oil line going to wing/oil cooler. I suggest an additional heater strip on your oil cooler "radiator". Of course, a heated hanger would be best, but I do not have that option! Good luck. -------- Daniel Booker &quot;Stealth-Eagle Aviation&quot; 2312457798 danbooker@hotmail.com Read this topic online here: http://forums.matronics.com/viewtopic.php?p=447880#447880

    Do not chase wires. Not worth it. Many cannon plugs have jumpers in them. Just unscrew them and tie them up.

    I've mentioned this before, but it is worth repeating I suppose. The original YAK-50 came with a type of "Veritherm", think of it as working the same way as the thermostat in your engines cooling system. It screws into the standard M-14 oil cooler that is found on both the 50, 52, 55 and Sukhoi's as well. You'll also find a Veritherm in U.S. made oil coolers on many models. For reasons unknown, Russia put out a directive to remove these devices from the YAK-50's. However they can still be found in the Russian helicopter oil coolers. Long story short, they are not easy to find, but they are out there, and they do work extremely well. Vladimir Yastremski happened to come across one, and I had him put it back in my otherwise stock oil cooler. I immediately noticed faster oil warm-up times, and a much more stable oil temperature reading. This also gives a pressure by-pass to the oil cooler when the oil is cold. The oil temp also remains much more stable when flying, obviously because it is now regulated just like your car engines water temperature (more or less anyway). There has to be some reason why the Russians pulled this thing out, but it can't be THAT bad since they left them in every helicopter oil cooler. In any case, I've run this one over 500 hours without an issue. The only problem is finding one, but it's worth thinking about.

    Subject: Gyro removal
    Concur on just removing the hardware and tying back the cannon plugs. Why? As time progresses it can be quite handy to have wiring and a breaker already in place to power a 28 VDC item. The inverters drew a fair amount of current, so you have future growth capability in place. In the meantime, just leave the inverter switches/breakers off. My former Inverter wiring now powers my transponder and Mode C encoder. Just a thought.

The original YAK-50 came with a type of "Veritherm", think of it as working the same way as the thermostat in your engines cooling system. It screws into the standard M-14 oil cooler that is found on both the 50, 52, 55 and Sukhoi's as well. You'll also find a Veritherm in U.S. made oil coolers on many models. For reasons unknown, Russia put out a directive to remove these devices from the YAK-50's. However they can still be found in the Russian helicopter oil coolers. Long story short, they are not easy to find, but they are out there, and they do work extremely well. Vladimir Yastremski happened to come across one, and I had him put it back in my otherwise stock oil cooler. I immediately noticed faster oil warm-up times, and a much more stable oil temperature reading. This also gives a pressure by-pass to the oil cooler when the oil is cold. The oil temp also remains much more stable when flying, obviously because it is now regulated just like your car engines water temperature (more or less anyway). There has to be some reason why the Russians pulled this thing out, but it can't be THAT bad since they left them in every helicopter oil cooler. In any case, I've run this one over 500 hours without an issue. The only problem is finding one, but it's worth thinking about.

They work great. Only problem is I preheated engine compartment and still blue an oil line going to wing/oil cooler. I suggest an additional heater strip on your oil cooler "radiator". Of course, a heated hanger would be best, but I do not have that option! Good luck. -------- Daniel Booker &quot;Stealth-Eagle Aviation&quot; 2312457798 danbooker@hotmail.com Read this topic online here: http://forums.matronics.com/viewtopic.php?p=447880#447880 bsp; -=============== =================================== ="http://www.matronics.com/Navigator?Yak-List">http://www.matronics.com/Navi gator?Yak-List =================================== ms.matronics.com/">http://forums.matronics.com =================================== tp://www.matronics.com/contribution">http://www.matronics.com/contribution ===================================
