Silvery Metal Upgrade Kit for E_Sky Lama V3/V4 R/C Helicopter

Pros: This thing improved performance, and reduced blade strike considerably.
Since the wing axles doesn't bend, the heli has much better lift and acceleration up.
It's also a LOT more responsive in all directions.
Flies more stable, I can now fly with gyro gain at minimum. (Or I got better from crashing all the time)

Cons: Doesn't eliminate blade strike entirely, and it's was a pain in the a to assemble, tons of miniature screws.
Needs permanent threadlock to stay together. This is a stronge kind of threadlock, you cannot disassemble this afterwards. Not for the faint of heart.
Some of the servo link arms will move around unless glued properly.
There's no ball bearings included for the centre axle, had to re-purpose the old one.
(the one on top of the tube/outer axle)

Other: Proper upgrade kit, quality is above expectations, improves handling.
Requires permanent threadlock, can be bought in any hardware store.

Pros: it look nice the sliver went together very well use thread locker blue. the price is cheap for these part. did not use the main blade grip set to hold the blade because when i did i had tbe when i took then off and use the old one the tbe was gone.and no blade hit each other.

Cons: none real i use the swash plate,bottom central holder set and the center hub and shaft

Other: for the price it work for a good upgrade. look at price in USA and would of cost me lot more.
