Using micro helicopter like (aerohawk, dragonfly, ect) flying over the enemy line is no diff. then just poor your money into the iraq sand.... i mean... and talking about spying... lol.... i mean.. these thing don't even fly that long.. unless u have lipo and brushless... and you're already talking about upgrading... cnc head and all that crap... I currently have an aerohawk... and i also have a wire less spy cam... and trust me.... u can use it to spy on YOUR CAT.... your wife.... not YOUR ENEMY... One problem which i believe is the biggest from micro helicopter is.. they will get SMACK by the wind... 4-5 mph... and they can hardly stay in same altitude... go up and down crazy due to fix pitch... And tail motor problem.. lol... 70% chance that ur tail motor will burn out... and guess wut??? "the end" ... SO what i suggest is mid size helicopter... Eco 16... helicopter that has CP and Tail Drive Shaft...
