This is the 4 bladed tail rotor head I ordered from CNCHelicopters. Man I love this new tail head! Tail is rock solid with this head! Took me a little bit to get the tail trimmed out right, but once I did, man it's awesome! Super smooth!
You use a 4 bladed tail when you are using a 4+ blade head. Helps compensate for the extra drag of the extra blades. Looking good, now we need video hehe.
Tony, I'm using it with the DFC head and it works great! Graham, you can get one from CNCHELICOPTERS.com for 36.00! They are pretty reasonable! I love mine!
