Good I just got a 450L with the same Gyro and ESC from ebay with enough parts to build two. Do you also have the programming tool for the ESC? I should have it by the end of the week.
If I am not mistaken I think those tgy servos need to have the lower case cap insulated. Just pop off the bottom cap and place a piece of electrical tape on it. Or use a liquid electrical insulator. The KSTs don't need that done.
