what engine have you been using them in,just would like to know if it makes a difference on the top self engines too.
i have DA's and BME's also, and would like to know if they could use a FB ring.
Frank makes rings for just about every one of our hobby engines and I have been using them for several years, and have installed them in Italian made Super Tigres, Zenoahs and DA engines.
