Xl CDE build

[stikflyer]

I just purchased an XL CDE, It is assembled but I want to disassemble it and build it myself from scratch. There is quite a lot of fasteners and parts left over so i think the guy who originally built it may have missed a few things( I may be wrong).
Which of Bob's videos should I use, the SE build or should I use the Xl HDE build videos?
How much if any play should there be in the main rotor blades? If I take the blades in either hand and pull they separate nearly 1/4 " This seems like a lot to me but I am new to heli's and just learning.
Thanks,
Kevin.

The left over parts are from the spares bag. if he missed something out something would be flapping about.

use the SE setup, the only difference is when Bob does the servo arms, you will have to set all the servo arms and CCPM mixing arms up at 90deg. the push/pull links will not be parallel but you will be able to split the difference (even both sides through the centreline). just make sure the servo arms are parallel to the main shaft and that the collective arms are also parallel.

the base point is given to you by the elevator assembly. it has to be setup 90deg at middle stick and 0deg pitch (this is a little tricky as you only have a fairly small lever arm to line up with the main shaft), then level the swash up to that setting using the links between the collective arms and the swash.

from there on up it is the same as the SE.

there should not be much more than about 1.5mm between the blade grip and the head block. the bearings can slide in the blade grip and allow the blade grip to slide towrads the head block. centrifical force will keep them properly seated. but make sure the blade grips are pulled out before spooling up as the shock load when the blade grip slips on the bearings into the seat could break stuff. the vibrations would be terrible till the blade grips both seated properly.
