With a ZDZ 80 this plane is 21-22 pounds. When I was building mine I believe that I estimated the weight would be right at 20 pounds with the DA50 with a Pitts muffler.

Even with the 80cc the batteries have to be pretty far forward to balance it... With the DA50 the manual shows the RX pack on a plank over the engine!

I currently have a Extreme Flight Yak with a DA50 it weighs 17.9 pounds... I need to shed at least a pound off of that.... In my opinion the max 3D flying weight for the DA50 is about 17 pounds. Sure you can add tuned pipes and maybe that will help, but 20 pounds is a lot to ask of a 50cc motor.

With the 2.3 if you go all out to keep the weight down. I'd bet 19 pounds is the best you can get.

Hope that helps
