HK450pro + 5 blade head problem

hello

i have a hk450 pro and a 5 blade head in order to fit in a hugue 500 scale heli

in ordered these items end of 2011 and assembly now.

in fact the length of the long arm (horizontal)on the swashplate is not enough to go the anti rotation bracket supplied with the hk450 pro kit

Somebody has experienced this problem and how to solve it.

if HK people read this please help me

in fact the anti rotation bracket on the HK 450 TT pro is not so close to tha rotor mainshaft so there is a diffrence about 8 mm less on the axis fitted on the 5 blade swahsplate and going between the anti rotation bracket.

I have two solution to remove the long pin on the HK 450 tt pro swahplate and fit this on the 5 blade swashplate or to move the anti rotation bracket more closer to the mainshaft, in the last option there is no position design for such solution and i don't know if the servo arm could work properly

You might have to create an extension to the existing tube & ball joint using a piece of steel tube that will fit over it. Reduce it back to the original size where it slips through the guide slot.

You can create something strong enough using epoxy - insert a bit of screw thread inside for extra strength.
