Hi everyone, Here's Hulk Jr. with his 360mm blades that finally arrived last Saturday :banana: :boldblue: Now can begin work on final detailing (including cockpit) and painting while fran11784 does the FBL setup. Always checking everything with a fine tooth comb. As you can see for a 450 size, Hulk Jr. is a beast!. Weigh him yesterday at 2 lbs. & 2 oz's. I replaced both the ESC from 30 amps to 40 amps and the motor from a 3550kv to a 3700kv. He has a duel 3 cell setup with each rated at 2200 50c that replaced the 1800's The 360mm carbon fiber blades are also wider than the 325mm in mass. Don't see a problem with lift. I'll set up the pitch 40, 42.5, 50, 75, & 100. Don't want a lot of negative pitch, -3 max. Throttle curve will be 0,25,50,75 & 100%. Have to work on dual rates settings. Metal springs fran11784 gave me are a prefect fit and strong enough to absorb any landing. The hollow wooden tubing Rackman sent me are not only light but strong for the landing gear assembly. And again this wouldn't be possible without buel williams help, who got me the 470 size belt. Thank you all :peaceful:

This is the very first scratch built helicopter ever attempted. Last year this time was daydreaming and drawing rough ideas on paper, what a challenge. Lost count of the many changes made. Finally coming together and wouldn't got this far without the support from everybody in the Forum. Won't rush into this but take my time and stay focus.
