Bought the 10 CA radio with the 2.4 hz set up when it was launched. The radio has worked flawlessly so far , however last weekend, I realized that the throttle trim would only work in the upwards direction. Once I increased it to the maximum, I could not bring it down. We fly in Mumbai, where temperatures are approx 95 F and the set was placed in open shade between flights. I soon discovered that 2 other club members had a similar experience with the same set! To get the trim switch functional , they recommended cleaning the switch with gasoline , injected through a hypodermic.
Anyway , I switched of the set , placed it in an air-conditioned car and 45 mins later it was back to normal !

Would appreciate your thoughts on this.

Cheers
