Greetings Dogz,

I Have flown a lot of electric planes, but I must agree. The Crazy Max is the most bang for the buck.
There could be another little reason. I use the 8 cell 800 nhm pack from HP, and if it slides back to far it interfers with the rudder and elevator servos.
Some use nicads, but at 8 cells, count on replacing the motor around every 30-40 flight or so.

Now, here is a really nice, and cheap upgrade. Replace the gears with the WattAge 4.25:1 set and mount the WattAge 10x4.7 EP Prop. I also made a new and longer set of landing gear.
I flys a little slower, but she really pulls now.
With the nhm pack, I get around 5 minutes of wild flight.
So thats that.
I hope you get it dialed in, its a great plane.

Jared
