Guess you said that, sorry, something got lost in the translation... I don't know of any for a throttle. Honestly, the only airplanes that I have flown that have vernior throttles are Bonanzas, and I always thought they were annoying. To each their own I guess. I never thought it all too important to be able to micro move the throttle. Mine are usually wide open most of the time anyway
