||Here is the best place to buy this heli a Reduced price and wonderful support. (Thanks Amain).
Blade 130x is a great heli that do every thing 450 heli's will do. but I have a bad luck with it in the third flight the tail case come loose while flying and make me a bad crash and I lost the tail gears. (I prefer to put a small drop of CA on the tail case to avoid come loose while flying). anyway the kit come with a spare gears. the weak piont in this heli is the tail so I order from here a good upgrade for the tail.
If I were you I will buy this parts with this heli
1- BLH3736 (spare) gears.
2- LYX0458 (upgrade) tail boom.
3- LYX0487 (upgrade) tail case combo.
