Default Cox Christen Eagle Lipo's

Hello Everyone, I'm new to electric power and have a question about Lipo packs. I bought a Cox Christen Eagle ARF and wanted extra batteries which Cox does not sell so I bought 2 common sense rc batteries and need to know if they will work. The stock battery is a 3S, 11.1v 1800mah with no output rating. Tech support at Cox said it was rated at 18amps continuous discharge although the esc is rated at 16amps. The common sense battery is a 8C, 3S, 11.1v, 2000mah rated at 16amp continuous discharge. I,ve made adjustments for the size and weight difference and CG is OK and have only done some taxi testing so far. My question is will there be a problem with the difference in continuous discharge rates? Also, the common sense battery has a burst rate of 24amps for 5 sec every 30 seconds. Any help would be appreciated. Thanks, Marty

PS: I've also noticed that my horizontal stabilizer is not square to the fuse. It has about a 5/16in. offset from square and the same amount off center. Seems like this may cause some yaw when heavy elevator is applied. I've built many nitro planes so I'm not sure how much affect this will have as I always built them square. Plan to contact Cox about this, but I only realized the problem during final set-up so I'm going to give her a try anyway. Anyone have any experience with this?
