I HAD A ZDZ 80RV ON A 33 SD MODELS YAK. THE PLANE FLEW FINE , BUT I DIDNT HAVE ALL THE POWER I WISH I DID. I BOUGHT A NEWD SD YAK AFTER A HOVER CRASH. I HAVE MY ZDZ FOR SALE AND I HAVE A DEAL WITH SOMEONE PENDING FOR A TRADE OF A BME USED_GOOD CONDITION BME 102 IN RETURN FOR MY ZDZ PLUS LIKE 200 BUCKS. I WAS GOIN TO SELL MY ZDZ FOR 550 SO I CAN GO INTO A 100 CC .THIS PERSON WAS SELLING HIS BME FOR 745, SO I JUST TOLD HIM ILL GIVE HIM THE DIFFERENCE PLUS MY ENGINE. I JUST DIDNT HAVE THE MONEY TO BUY A NEW DA 100 FOR $1,150. MY QUESTION IS . IS IT WORTH IT GOIN TO THE BME 102 INSTEAD OF KEEPING MY ZDZ 80RV. I DONT SEE ANY HORSEPOWER OUPUT ANYWHERE FOR THE BME 102. I KNOWY THEY ARE LIGHT , BUT I JUST WANT TO KNOW WHAT YOU GUYS THOUGHT. THANKS

i had a bme 100 that i had converted to a bme 111 and the bme is about on par with the power of an 80-85 cc motor but i think the da-85 can beat or would beat my bme 100. the 102 is close to 5 lbs not sure what a zdz weights. bme has gotton a bad rap in the years for service the company has a new owner who is getting it up and running as we speak. the bme also needs to be prop in the 26 range as it likes to be up in rpm if it were me i would keep my motor or get a super 80zdz

so you dont think there is any gains in power in a bme 102 over a regular zdz 80. dammit i might be wasting money then.

mine would spin a 26 x 10 mejzlik in the low 6k range about 6100-6300 off memory. most 80 will do that if not more......

yeah thas what my zdz would spin with a 26-10. i have a question. how much less than a da 100 is the bme 102?

how much less what rpm, cost or what?

yeah rpm and horsepower. is th bme 102 less powerfull than aa da 100?

You are further ahead to get a pipe setup and keep the 80

the da 100 and 3w 106 will blow that away they want 27 or 28 inch props for most brands.....

thanks for the replies guys
