Default Sky Scooter battery issue

I recently purchased a Sky Scooter Pro (not ProII) at my LHS at a great price. After 3 outings with the plane I am very pleased with one exeption. Even after many cyclings, the stock 7-cell 600mah pack that came with the plane just doesn't last long enough for my liking. I went back to my LHS and asked for suggestions on getting a longer run time out of each flight. It was recommended that I 'up size' to a 8-cell 1100mha pack. I purchased one, took it home and made the necessary mods to the battery slot in the foam to accomodate the extra cell. Even so I was able to keep the CG in the same location as stock.

I charged the new battery and headed off to the field. I hit the throttle and the Scooter left my hand with authority--much more than with the stock pack. I throttled back a bit to approximately 3/4 throttle. Everything seemed fine until about 3 minutes into the flight--then the prop came off. I was able to dead-stick the Scooter for a decent landing without damage. Upon examination, I noticed that the hot glue that surrounds and holds the motor in the airframe had melted. Also the motor shaft was so hot and that I couldn't touch it. I came to the conclusion that the prop hub melted causing the prop to be lost in flight. I packed up and headed home contemplating what had just happened. Once home, and after everything cooled down I retested the system for just a minute or so using the stock 600mah pack to make sure the ESC was still working properly. Everything seems to be fine.

Is there a better pack for me to use to achieve longer run time or is the 600 mah the most I can use? A little more power would be nice but all I really am looking for is a longer run time.

Thanks-

Default Sky Scooter battery issue

I use Radio Shack 1600mah battery in my Scooter but I also cut cooling holes for the motor. I also have installed a Servo City gear box instead of the factory one. I too have pitched a prop off but I account that for the set screw not being tight enough. I use clear silicone to hold the gearbox to the front of the plane.
I am getting about 10+ minutes of flying time depending on throttle usage, loops and barrel rolls I do....

Default Cooling Vents!!!!

Hello,
Definitely cut 2 cooling slots to vent the rear of the motor. Mine had a scoop installed on one side. I used part of a plastic spoon. Worked very well. Also, I use foam safe CA to remount the motor when the factory hot glue melts. The Radio Shack 8 cell 1600mah battery is the way to go. I had a prop where the setscrew was stripped from the factory and would not stay on. I threw it away and put a new one on-problem solved. If you get really aggressive with the plane I would suggest a very small diameter carbon fiber rod for a wing spar. One half of my wing ripped off from about 200 feet in the air...not much left after that.

Yup the Radio Shack is the best Batt for the SS. Get you a Servo City Gearbox, 9 x 6 Prop & this battery for great preformance and flight time!
