    RE: YS-FZ 70

    I am thinking about this engine for my new UCD 46 build. I wonder if it will give this bird unlimited vertical. I suppose it will cost me $350 to find out

    RE: YS-FZ 70

    I have one but have yet to run it.  I thought I better obtain the engine quickly as (1) it would go out of stock and (2) not be produced any more for whatever reason.  I think the regulator problems are behind us now with the new set up.  Only time will tell.  Got to wear out my 63FZ first.

    RE: YS-FZ 70

    I have one bad new regulator and one good new regulator. I liked the 63S reg. better. You could adjust the midrange.

    Can we assume you are talking about the 70s?....If so, would you mind telling us why one is "Bad"....Thanks

    RE: YS-FZ 70

    Me thinks there is confusion here between a YS 63s and a YS 63FZ, where there are two different locations for the regulators. The YS 70 regulator is on the back near the carb (the HSN threads its way into the carb sort of through the new regulator mount). The new regulator is not repeat not adjustable, it is fixed internally. So the YS70 is a totally different configuration from the YS 63's.

    RE: YS-FZ 70

    That is correct. One of the new 70 regulators, same as on the 50/56 heli 2-strokes including cutout in the wrong place to avoid the needle valve, is defective. I mean the outer part with the valve and spring. I swapped it out and it runs as it should. I note that this piece cannot be bought separately! Yamada has a long history of adjustable - not adjustable. The new spangle 70 regulator is NOT ADJUSTABLE. That might be OK if there was a midrange adjustment on the carb. No such luck.
