There are two ways to treat a piccolo...the first is to soup them up and make mini hot rods..this makes them extremely expensive and faster,twitchy ( some will say more stable)and breakable...
The second is to help them to be what they were designed to be...an indoor fun flyer...This is not a popular idea and no one will tell you this except me...If your home and watching tv and bored wouldn't it be cool to lift off a micro and fly it down the hall and back again?...then land on the coffee table?..and be relaxed at the same time?...you can do this easily by "dumbing" down the piccolo...As I said most flyers feel the need to do the opposite and they try to make a micro fly like a big bird...By dumbing down the piccolo you can make a tame livingroom flyer that you can fly while sitting in your favorite chair..and in my opinion this is much much more fun than having a wizzing speedster zipping around like a house fly...
to dumb down a piccolo you only need to do two things...buy some tuning blades ( the kind with blubs on the tips ) and put wheel collars on the flybar for weight..You can put 2 or 4 wheel collars on the flybar..a set towards the head and a set out by the paddles..A set out by the paddles is fine for me..
The blades and weight help to dampen the pendulem effect of a piccolo and almost gets it to hover hands off..
The pendulem effect is over come by remembering that any stick input must be immediately countered by the opposite stick input..After awhile you will see the effect coming and you wont even notice it anymore because you will become sensitive to inputs...
Lipos will make you forget that it's even electric and they seem to fly forever...
I have a cheap Ikarus auto hub on mine and I love it...alot of flyers cant tell the difference but you can dump the throttle to autorotate and still recover before hitting the deck..with an auto hub you can even pump the throttle and float about..this cuts down on nerves...
If you choose the hotrod method thats ok too...have fun
