I strongly suspect you don't want to be puting NiZn in a TX. The 1.6v is nominal and they get more like 1.8-1.9v on full charge. :concern: My experience is they hold it better than old non-LSD NiMh...

If you crashed it badly enough to need replacement and have that kind of space requirement you probably would be well off to just get a replacement until you have your flying chops down better.
