RE: What does your 30% Carden Cap weigh?
Mine weighed 21.5 lbs with a ZDZ 80 on a KS tuned canister muffler, Still flew very light with no bad characteristics. The 80. was so overpowered that it was difficult to fly so, I have switched to a ZDZ 60 with canister. haven't re-weighed it but, I'm probably about 4-5 oz lighter.
5 x 8411's in it, 811 on throttle, 517 on choke, 2x 1650 nimh packs,
