Header Tank Mod for HPI Savage X 4.6 / XL 5.9

solves the HTL problem by using a additional 60cc header tank used by nitro 3D helicopters.

plus it gives a longer runtime per tank, 160cc stock vs 220cc with this upgrade.

all parts are printed with PETG

for the X 4.6 you need:

1x brace v1

2x tank holder v1

2x m3x8mm screws

2x nuts

2x washer

2x slightly longer shock screws

for the XL 5.9 you need:

1x ziptie

2x tank holder v2

1x 102526 XL Rollcage (if your XL doesnt have one, X Cage WONT WORK!)

Note to brace v3 (for X & XL):

2x zipties

2x slightly longer shock screws

Brace v3 is intendented to ziptie on the tank straight to it, without the need to print 3 separate parts and additional screws.

of course you can also use the v1 & v3 on the xl aswell, but it is less protected when landing on the rear.

also prefill the header tank by using a syringe or a pump (as seen in the videos below), filling it up by using the start drill or pullstart is a pain :)
