Hey flatlandmike, the couple of 2.3 extra that I know of in my area are both around the 19.5 pound mark with the DA50 and pipe,cant remember the exact AUW but I know they are no heavier then 19.5.
ORIGINAL: flatlandmike
well comp arfs site lists the weight for the 2.3 at 20 to 22 pounds i bet that most built are nearer the 22 pounds so imho i would want the bigger engine not so much a da 5o now when da gets that 75 then the 2.3 guys will be performing many upgrades to there engine and i bet the 75 wont weigh to much more than the 50 and will prob see a 2.3 that flys just like the 2.6 da100 combo
these are my slightly educated opinions no actual real world exp with the ca planes
what ide like to see is ca list there wing areas and all companys list all the info on there products
