well, gasoline + redline oil now costs me around $3/gallon, vs. around $6.50/gallon for home-made FAI fuel (methanol from a go-cart supplier, plus 20% to 22% castor), suddenly the extra $350 - $400 spent on the DA will require over 600 flights to start saving me money. Actually, the extra 11 oz. weight of the DA will make a huge difference in the flying capabilities of your Edge as well. YMMV.
Of course, the DA50R IS a great engine with unbelievable power.

Mark don't waste your time on a glow motor. Will take you to the poor house if you fly alot. Go with the DA 50 power second to none and most of all execellent customer service. A great power band and will last you forever oh did i say (customer service).
