If you are type of person who thinks it's fine to break rules because you're not very likely to get caught then you can change Tx crystals. It's only illegal not impossible. Oddly enough it's perfectly legal in most countries other than the USA.



For your information I write rules and I do my best to see they are enforced at our city field but some rules are stupid and beyond our control and make no sense.
* Money does not grow off of a tree for me along with millions of others. I read the rules and make my own decision. I am not going to spend 3 months building a plane at around $1200 to play frequency games unless i know what I am doing.
* I have four solid years in this and no crashes. Not because I am good because compared to local talent, I am a fair R/C pilot, but because i am careful. There are two simple rules i fly by.
1. I build at home, the field is for flying. If you run into field builders, stay as far away as possible.
2. If anything goes wrong that requires a tear down, then pack it up and hang out for a while with the guys, help out or whatever but leave that mess for the house.
Anyways to get back on track, Futaba wrote this stuff not me

* One of you guys just stated people do get hurt and die but mostly from stupidity and radios in proper working order. Pilots losing planes-I got a radio hit. Well those who understand how "hits" work will look alot further than the impound area.
* Radio wattage does not have to be very powerful to travel great distances. You can get hit from a guy flying an r/c plane a hundred miles away if conditions are right.
Whatever the case, go with the MFG's . I'll tell you this , I have never seen a plane completely replaced by and MFG due to radio failure.
