RE: Nitro Helis Vs. Electric Helis
One thing that wasn't mentioned is to use the softer head dampeners when you build the kit. These go into the head block where the feathering shaft inserts into. If you use a low head speed (recommended) and have the black dampeners installed, it'll wobble and look like it's gonna come down. Use the gray ones. Also use the included 14 tooth pinion on your motor so you can also keep the RPMs low.
Down the road another thing to keep in mind is that when you want to boost the performance of the heli, you can always add more cells. This is the one advantage that the electric helis have over the nitros. The stock Align electronics won't work with more than 6 cells so you'd have to do some upgrading, but I think it might be more important to learn how to fly the heli before you start thinking about that.
