RE: Question
get a walkera 4#4 from michael at ushobbysupply, or a falcon 40, or a hbfp version 4 - all are less than $100 - the walkera's weak spot is the tx, i had to replace the walkera 4-in-1 with a dynam 3-in-1 and receiver and use the control from the dynam hughes 300 - the dynam hughes 300 is mostly the same as the hbfp v4 except has the short walkera 4#4 tail boom
crashproofing the little single rotors once you get them is easy - single rotors are inherently unstable and fly different (you can say that again!) from the coaxials
been over this before - pm me if you need the instructions
most damage is, in order, skids (if you don't install superskids), blades (of course), the flybar stick (if not replaced with metal wire), tail rotor parts (without a tail rotor protector, even with it they can vaporize and dissappear), flybar control frame balls, flybar to blade linkages, rotor head - so be sure to order spares of these parts
