I measured the pressure in the left Main Gear to be close to the documented 65/18 kgcm2 in the lower / upper part. Could a lack of oil make the shocks stay in a half-compressed state when on the ground? What would be the effect if they were filled with air instead of nitrogen? Does someone have a procedure for filling oil in the shock absorbers for a Yak18T, and what type of oil is needed. My documentation says 755cm3 / 355cm3 of AMT-10 oil for main & front chocks =93 what is the western equivalent of AMT-10 oil Any ideas? Thank You Michael Wikstrom La Colle sur Loup, France Yak18T =93 F-HMSS ________________________________ Message 2 _____________________________________ Time: 07:29:24 PM PST US Subject: Yak-List: Prop adjustment M-14p From: "glipaz" Asking the smarties on here. I fly a Nanchang with a stock M-14p motor and an MT 250 prop. When I push the nose down my RPMs increase without touching the prop lever. Assuming the governor is set up properly, if my RPMs increase when I go downhill would it be a spring issue in the governor?

I previously had an MT250 fitted as well even with the Stronger spring it exhibited a little of this behaviour. I now have a 265cm MC400C from Whirlwind aviation fitted it still exhibits a little of this. (BTW the Whirlwind prop in formation (Straight and form aeros) is a dramatic improvement over the previously fitted MT prop) -------- Sean Trestrail ttail[at]internode.on.net Read this topic online here: http://forums.matronics.com/viewtopic.php?p=513677#513677 ________________________________ Message 4 _____________________________________ Time: 09:52:40 PM PST US Subject: Yak-List: Re: Prop adjustment M-14p From: "glipaz" Yes, I sent the governor to MT for a stronger spring.
