Howdy bill, Dont use the heli mode on the radio, The Corona flies with any standard 4 channel radio. Theres no mixing of the throttle and the collective which the LMH dosent have. Use it in airplane mode. Dont mix anything. The LMH is a very basic helicopter. That was the reason for your crash(pilot error). Sorry to hear about your crash but that sounds like a quick fix. Disassemble your tail rotor shaft and run a 3/8 dowel down the tube. You can lightly tap out the dented section as you force the dowel down the tube. I have heard of people using a 3/8 steel rod to do the same just have to make sure you taper and deburr one end of the steel rod. On your servo arm thats easily replaced but also take your servo top off and inspect the gears to see if you didnt break out some teeth also. If you did, you will need to get a gear set for that servo. Youre right about flying the full size heli such as the Jet Ranger I have a little stick time under my belt also in the 206. It would probably be the same if you scaled up the wind speeds to what the Corona has to deal with. Boy would that be a ride. A dent in the tailboom is just part of the initiation into the club.
