The Sky Ranger has a built in Lithium-polyester (Li-PO) rechargeable battery to operate the motors. The transmitter uses 6 AA batteries to transmit and to recharge the on board Li-Po. Susposed to get about 4 or 5 full charges off of a set of AAs. About 6 or 7 flights of 2 minutes (a long time for a beginner) per full charge. Another plus is that it is very small for a RC plane,very easy to take along. About 12" span and about 13" length. That also is it's major drawback. It is so light(.95 oz) that you need nearly dead calm to fly in. No more than 4 or 5 mph for good flyers(not me yet). This is the cheapest way to try out RC planes that I have found and the plane has a good pedigree. Designed by a well known free-flight designer. Keep me posted if you jump in.
