Walkera 4G6 with HK-250 GT tail rotor grips
Walkera 4G6 with HK250 tail rotor grips
Just tested the Walkera 4G6 with HK-250 GT tail rotor grips and hub. Very nice!
The HK250 tailshaft is 2mm so i had to use some shrinktube on the 4G6 tailshaft which is only 1.5mm. I removed the hub from the original Walkera tailshaft. With shrinktube, fit is perfect and secured by a grubscrew in the hub.

The Walkera metal balllinks have been epoxied into the bladegrips. I also made some new 1mm CF tailblades with sanded airfoil. Had to use a little piece of 0.5mm CF as a space as the HK-250 GT tailblades are 1mm.

Additional weight is 1.2 gm. Result is a perfectly solid tail. Only drawback is that the pitchslider trave is slightly reduced (by about 2mm), resulting i slower piro rates. I might make a custom tailshaft from 1.5mm steel which is slightly longer than the original walkera shaft.
Now i only need the new pitchslider from Hardy and this will be the perfect 4G6 tail.
size comparison
Also with Hardys blade grip mod (inlays) i will do a direct comparison between the modded Walkera plastic bladehoders and the HK-250 GT parts.
