Our ceramic bearings are made from Silicon Nitride. Silicon Nitride ceramic bearings are the smoothest bearings available for your helicopter today, with next to no wear plus Silicon Nitride ceramic bearings will decrease friction which means less wear caused by vibration on other parts of your helicopter, less heat buildup and improve flight times and ultimately more power.
The list say "4x8x3 Silicone Nitride Ball (2pc)"
2 pieces !?
There are 4 of theese bearings in the head, two in each bladegrip.
Is this an error in the text or in the kit ???
are these bearings for the 450 pro or V2 kits?
I have a couple millimeters of movement up and down at the tips of my main blades even with the feathering shaft done up tight. Will these eliminate that?
Cheers,
Jamie
how come i have a sealed bearing in the end of the rotor blade holder and one inside the blade holder then the washer thrust bearing and washer on the end of the feathering shaft this picture shows only the thrust bearing inside the blade holder and one sealed bearing in the mainshaft end of the blade holder
They will last longer than the stock bearings.Ceramic bearing resist wear better than metal.and you will have to replace those stock bearing one day, lets say 50 or so flites.do you oil daily,the bearing? good luck!
i think the only bearings in the head that would benefit from swapping to ceramic would be the thrust bearings... i really don't see the point. i would rather spend my upgrade $ on something else. =(
i would definitely buy if this set were: main bearings thrust bearings one way tail drivetrain tail drivetrain
Assuming you do a lot of action (meaning not hovering all the time), the bearings sold here have to "work" quite a bit: each time the head spins once, they get turned by a few degrees and back. That could be even more stressy for the bearings than just going in circles like the main shaft bearing does. Try rotating your heli with and without the head installed to get an idea how much friction you got there.
What about the swashplate! The outer swash bearing is the one you need to have high grade. You can replace all those bearings, but with a worn swash, the head is still loose.
looks like a nice upgrade, but im not sure the heli will fly any different. i geuss getting better bearings on the main shaft and tail would be more useful for efficiency.
I don't think so Xav ** BER0004 and BER0009 both have inner diameters of 4mm (according to the specifications), which suggests the V2 / Sport / Pro feathering shaft size. NB: "2.5" and "3" are the thickness of bearings.
items as described, it fits on V2 head. but i think that 10 x 2*5*2.5mm ceramic bearings for mixing arms is not very useful for heli head. i put it in a motors for Lama V4 :)
