Well I have to agree with a sim is the easiest way of learning to fly, but isn't the end all. My first heli was a raptor 30 v2 and i ditched that numerous times, sometimes a set of blades and tail boom at about 30 quid, other times it would cost me 150 quid in parts.
Helis have got cheaper over the years, I had my raptor 9 years ago, and they've come down as electric has got more popular. 3 years ago I decided to get back into helis, and bought a sceadu evo 50, bigger that my raptor and i've flown it a handful of times, due to time constraints and weather. When I did take it out it was hard at first so decided to buy a simulator, aerofly professional deluxe. While it's not as good as that it's still good for getting some time on the sticks, and allows me to keep familar with the controls. Only problem I find is i get bored of the sim, due to it being on a computer.
I then decided to buy a twister cp v2, which is a smallish electric heli, absolutely brilliant, stick it in car and use it at work in sports hall. Can fly it a lot of places where the sceadu won't. I had the twister out earlier in the garden, and all was fine till the wind got hold of it, forgot how light it was and it shot up, managed to control it, but was a reminder of how things can go bad quick.
Out of the helis, I'm toying with building a trex 250 clone, due to it's size, but think a 450 would be better, just struggling to make my mind up. And for people who say helis are expensive, they don't have to be, but when you want better and better, they get real expensive real quick it seems. A new set of blade grips for the sceadu that are alloy are about £60ish, twister about £10.
I'd love a blade msr, due to being able to fly in living room, and twister is too big. well not too big, dog is just too interested in it!!
Now that the rant is over, I encourage everyone to have fun flying and when/if you do crash rebuild and learn from the mistake.
