Such a great kit! comes with belt idler which works really well. i recommend having the Goblin 420 manual aswell as the Devil 420 manual while building and reading both as you build, alot of good tips in both, also make sure to add the tail belt idler on before you mount the main alloy plate to the body.

started build and instruction manual for heli is not really clear. I have been building helios for several years and this heli is one of the better ones. the tolerance are very good but missing some "beauty washers". once done we will see how it flies.
