Just went 2.4 for all my planes. $710 for module and 5 receivers. Ouch!!! Still cheaper than even my smallest plane. Now I am protected from other peopls stupidity.
My main concern was safety. My plane weighs 45lbs and could do some serious harm. The heli blades could have cut up someone pretty bad also. We could have lost our field and I was surprised at the cra**y attitudes displayed by a few club members. Most of the members thought this was unacceptable and are going to bring it up at the regular meeting in 3 weeks. In the meantime and all of my own future I won't have to worry about it.
