Today the temperature here in New Jersey is 63f on a very cloudy and absolutely windless day.  So after four months of indoor flying I thought I'd try something new. 

Because the UDI-13A and WL-V911 are packed away with dead batteries (while waiting for summer) I took the s26 Chinook outside and immediately learned what happens when sunlight, even sunlight which is obscured by heavy clouds, overwhelms the infra-red control system.  It goes nuts! 

At first I'd thought the Chinook had finally succumbed to the effect of smashing into walls and ceilings and dropping to the floor.  The motor speed began to fluctuate wildly and the heli assumed a mind of its own.  It shot straight up, descended a bit, up again, then the motors quit and the heli dropped to the ground.  I noticed when I brought the throttle to full off, instead of instantly shutting down as the Chinook's motors normally do, the props continued to spin for a few seconds.

Convinced the Chinook was damaged I brought it inside but found it is working perfectly.  So even though I've repeatedly read that IR-controlled helis will not perform outdoors in daylight it took this experience to learn my lesson and I am now convinced.  So I'm charging up my RC birds and hoping the wind level remains at zero.
