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

This is not something we have ever heard of happening with the trim switch. We have many customers who use and fly this transmitter in the desert southwest and none have indicated a problem of this sort.

If dust or dirt had gotten into the switch, this might explain what happened, but gasoline should never be used on delicate electronic or plastic parts. Gasoline, nitro fuel and such are very hard on plastics and will cause the plastic to soften and crack.

In the future I would suggest a shot of canned air instead.
