Hi!

This will be my first gas engine and I have a few questions which have probably been asked before but I want to hear fresh opinions.

I'm looking for a 50cc engine that's very light, powerful, reliable and that vibrates less than the competitions engines.

The engine will be going in a 80" 3D plane and right now I'm looking into DA, ZDZ & BME but having had no experience with any of them, I have no idea which one should I choose.

BTW, please only comment if you have tried at least 2 of the 3 brands that I mentioned.

Thanks

All three engines you mention are fine products. It may help to know what kind of plane this is going in, as the DA and ZDZ are rear-carb'd engines, while the BME is a side carb'd engine. This will probably mean you will need to cut a hole in the firewall to accept the rear carbeurator.

That said, I will say I am biased towards the BME, since that is the only one of the three that I own. I can honestly say that my BME .50 has run like a top out-of-the box, and has plenty of power, unlimited vertical, on my H9 80" CAP 232.

Thanks for your reply!

Have you ever seen a DA or ZDZ run ? ... do they vibrate more than the BME does ?

This engine will be used in a custom Funtana 2.5m wingspan and my projected weight is 14lbs.

What prop are you using in your BME and what sort of rpm figures are you getting ?

Also, what muffler are you using in your BME ? ... if I get the BME50, I was thinking of using the standard muffler because of weight savnigs ... is there any advantage between the J&A vs the Standard exhaust ?

Thanks

I know 5 guys that have DA50 and the vibration isnt bad at all only at idol but the DA has more power than anything Ive seen and it wights less than anything

3DSWEPED, between zdz & da, which engine has less vibration at idle ?

That sounds like a DA50R

I'm a ZDZ man, so I would say ZDZ, BUT--- my next engine will be a DA just to see if there as good as a ZDZ. I do own two other manufacturers gas engines and still like the ZDZ . You cannot beat the ZDZ for ease of cranking and reliability.

Just my $.02

This question has been posted hear many times, whish 50cc its the best? I do own a DA50 and a ZDZ and a 3W, and on my opinion the DA its probably the best 50cc but if you are willing to compromise a bit and go for a slight heavier engine I would suggest the ZDZ 60 with a supersonic muffler, kills the DA 50 by a long way and you don't have to go for canister to increase performance as some guys are doing.
