My another upgrade for Trex500 EFL Pro just arrived. This is an upgrade for tail pitch control. I can say this is quite same as KDE Direct 500 performance tail control.

Items in box:
– Metal tail pitch part (H50189)
– Assembly / Instruction manual

Instruction manual. You have to use old tail grip blade set (Part on far left on manual). And please beware about thread lock. Its make a big warning that you have to use T22. This will help when you need to maintenance system.

All nut have to be clean and apply thread lock before put in. (You have to verify this)

Finished!
