I'm in the market for some more 4S2650's, so I'd like to hear what the actual weight is once you get it.
ccpdx is correct - I hadn't noticed the discrepancy on HK batteries before as they were for things like a Supercub or 1S packs for my UM planes.
Actual shipping wieght:
Nano-tech 4S 35-70c 2650: 284.4g
Individual boxes: 24.8g ea.
USPS box+bubble wrap: 95.1g
In comparison, the Sky lipo 4S 2650 40c is listed at 330g - I hope you are right about the Extra not being overly finicky about CG, Nanos are light!
One thing that concerned me about the Nano 2650s - their 'height' is 45mm. Hopefully I won't have to dremel the heck out of the battery compartment to jam them in.
DriverRX8 - have you had any issues with the canopy coming loose, and have you tried 5S yet? Also - are the wings a pain in the rear to remove/replace for travel to the field?
