SsZero-You will need to adjust a few things upon first flight. There is engine settings that need to be delt with. Top end mix, and idle mixtures. There is also the pitch curve and throttle curves. They will alow your heli to hover at a certain stick postion and certain head speed. Too much speed on the head and it becomes real twitchy for a new pilot. I dont know much about a Caliber but Ive owned the Concept 30 line and now a Sceadu and each heli is different. as long as you follow the instuctions by the letter you will be ok.
P.s- GET Realflight G2!!!!! It will save you alot of money and headaches. Its not a question of will you crash but a question of when and how often. G2 will help in getting your co-ordination down. Remeber your controlling 5 different things at once to get it to hover.
