I need some experienced help.  I have a HK450 V2 that I am building.  The only build manual I can find is the manual for the genuine T Rex 450 V2.  I am having trouble with the general setup.  I cannot figure out what length each of the linkages is to be.  Someone please help.

I found the lengths listed in the T Rex manual, but I have reason to believe that these lengths will not work with the HK450 V2 model because my linkages are not long enough to make them the lengths listed in the T Rex manual.

Can anyone tell me simply what all four proper lengths are? 

Thanks ahead of time for your help!

The link lengths from the T-Rex 450SE v2 manual are a good starting point. But during the CCPM steup process you will need to increase and decrease their length anyway to get a solid setup.

I had no problem with the lengths of the three swash control rods. My HK450GT and HK450v2 kit both came with the linkages at exactly the length described in the T-Rex 450SE v2 manual. Did you measure the right way? The T-Rex manual specifies the linkage length from the center of the ball-link-hole to the center of the other ball-link-hole.

Don't get too hung up of exact length - as r-g-r says they get changed again during setup.

They are simply starting points. Some of the supplied rods are not quite long enough or can be too long to achieve the specified lengths.

The important thing is to have each matching pair the same length to start with - ie the inner and outer swash pairs. Even these adjustments get altered during blade tracking adjustment.

The servo links are not critical and have to be shortened and lengthened during swash-leveling.
