I recently purchased and built the Dynam Hawk Sky and have flown it a couple times but after a few days I am running into some problems...
When I turn on the plane, one of the servos now makes a strange noise but every servo still functions until I attempt to turn up the throttle--now only goes up to about 20% power-- which runs for five seconds and then the entire plane just shuts down....
I have no idea what is going on--maybe a busted battery or ESC???
Do you have access to one of those wattmeters? That will give a LOT of information on how your motor/esc/battery is performing. If nothing else, check out one of those $5.00 digital multimeters from Harbor Freight. Low cost digital meters are available through a wide variety of places, including Wallyworld.
If you're not familiar with those digital multimeters, this might help:
(Note that this meter only has a 10 Amp DC current range, and your electric power system likely pulls more than 10 Amps.)
Hobbyking is one supplier that has a decent unit.
Here is a 30 Amp HK unit.
