Ralph: The "met your G26 match" in my post was to get more imput. Guess that may have worked. I owne a G38 Zenoah and had a G62...that I wish I never had sold. They are both very high quality engines, built to out last the owner!! I would like to see a few of these mac,s (MB290) with your ignition on them. It would put a nice little unit in the price range for the the tighter buget RC fans. Thanks Capt,n
