- - 3w-50??? (https://www.rcuniverse.com/forum/gas-engines-142/388237-3w-50-a.html)

Out of curiosity, and I know there has been a lot of talk in this engine class. Be it the new ZDZ-50, soon to be released DA 50, BME, etc

But I haven't heard much talk on 3W's answer to this engine class...Any one have any experience with this motor?? Is it just too heavy?? Any comments out there??

Ya, it's kind of heavy compared to the rest of the 50cc motors out there. It weighs closer to the 60cc motors. Maybe the warbirds need the nose weight.

Hands on experience - it is an extremely nice running engine-easy starting and smooth running.
Comparison with ZDZ 60 -which weighs less - is that the 50 will not pull big props (24x10 MenzS) as well - All of this was done using tuned exhaust setups - we tried various ones -different lengths etc. and both engines were operated under " best conditions ".
if weight is not a factor- it becomes a simple brand choice -in 50 size comparisons
Against the new ZDZ50 - weight of the 3W is considerably more -and power - based on single examples only - pretty darn close!
No solid "side by side"data yet.
Best apparant comparison is that smoothness is about the same - the new ZDZ50 - is very smooth.
