OK, yes, I had some spare time and an extra Skookum 720 w/GPS.

I installed it on the Walker 450, all went well and easy. All bench tested out.

Then came field day. I knew something was wrong right off the bat. It acted like the batter was low. I immediately shut it down, brought it inside and started checking it out.

Voltage to the 720 and motor was Low, and the warnings were present when I hooked my 720 up to my laptop.

QUESTION: For some reason, my Walker ESC does not like the Skookum 720.

I verified the ESC was Good, in fact I tried a known good one as well.

Anybody had this or a similar instance?

Looks like the Skookum wants it's own Power Supply!

We will see in a couple of days.

After 2 days of thinking and researching, it looks like I have a bad unit.

UPDATE: All Walkera original components are NOT compatible with today's gyro's, servo's, well everything.

Basically, I changed out all the electronics starting with the motor to the ESC. All mechanical components are original Walkera.

I like the way the Walkera flies, just waiting to see how it works with the new electronic components.

I have flown Align and Walkera 450's, RTF. Out of the box, I like the Walkera better. It's a great introductory Helicopter. Very calm and controllable.

JMO, Dennis

PS: I burned out two Walkera Servo's trying to make it work. Simply, they're not going to work properly with other brand ESC's and gyro's. You live and learn everyday.
