RE: Are BME engines any good ?
Okay, lets talk performance. .110cc's that will haul a 33 lbs 40% plane straight up at less than 3/4 throttle from a hover, or less than half throttle with a 28 lbs version of the same 40% plane, and both planes take off in less than 15 feet and will do multiple vertical snaps and keep going on track. Let's talk spinning the 28-10 Mejzlik in excess of 7000 rpm, the 28-10 Menz at 6500, the 29-10 Mejzlik at 6500, and the 29-10 Menz at over 6000. Let's talk about getting easy 18-20 minute flights on 32 ounces of gas. Let's talk about a decently smooth idle at 1300 rpm, and idling as low as 900 if you want to play with the carburetor, and a butter smooth midrange as well as a super strong top end power band. Let's talk about instant throttle response, NO overheating, AND saving 2 POUNDS over any other engine near it's size. Let's talk NO broken cranks. . EVER!! Sure can't say that about the competition, since I've seen both the other "big names" break 100 and 106cc crankshafts.
Now, we talked about it. . we've BEEN talking about it for 9 months. That pretty much sums it up in a paragraph.
