My 58 gx 2 has been starting ok i only have about 3 gal through it. In an effort to get it to run smooth at low rpm's i have tunned it but its not as dependable as my DA had been durring this prosses when the tank gets low the transition seems to go lean ill do touch and goes and twards the end of the tank she has failed to spool up and over run the runway as a result between that and the 6V decale on the ignition wire leading me to think it would run on a 6V battery ive lost 2 props and some cosmetic damages. Is a little extra power worth this? Im thinking not Ive spent weeks not wanting to fly the thing due to these issues as well as running low on Prop $ next time out im turning the low end screw out more and living with the burbles so much for 3-D flying this year unless it settles in soon
