RE: Gas engine vibration
I have both a zenoah g-20 and a saito 125 and the zenoah gas motor is smoother than the saito 125 glo. Both run excellent but there is a vast difference in fuel cost. The zenoah burns 5-6 oz of $3 per gal gas and oil and the saito burns 18-20 oz of $15 per gal glo. Guess which gets flown the most?
