Zippy Compact, the latest addition to our Zippy battery series offers excellent performance and high quality in a "Compact" size. These packs provide the same capacity and discharge rate as our Flightmax line, but give you alternative sizes for applications that require a specific shape.
Great for models with limited battery compartment space!
Zippy batteries deliver full capacity & discharge as well as being the best value batteries in the hobby market today!
It does fit Master CP although the ramp at the back of the cage tends to catch a little and indents on the plastic cover
Bought this pack to replace the dry batteries on my CTB6. It is just a tad thick but for the price I can live with just attaching it with velcro and leaving the battery door off. Only other pack I found that would fit with the door was about 16 bucks so this was a no brainer.
Quality looks good and so far a single charge was left on for 5 hours before i got tired and turned it off and it was still 3.8 volts lol...
So if you are looking for a pack to replace TX batteries this one is a good deal.
