I have a 38" span scaled up version of the Prairie Bird (a Peck rubber powered kit) using the same motor/gear box as in the TM, the IPS. With a 7 cell 550 mAh NiMH battery pack I get 35 minutes of full out flying time.

I then switched to a EPS 300C, as found in the GWS Zero and with a 7 cell 600AE mAH NiCad I get 20 minutes of aerobatics.

All this fun and I did not have to buy new batteries and charger. After all, the amount of fun you have is directly related to how much money you DON'T spend!!!!

fly SMALL, have a BALL
