Hi,

I recently received the Microheli's QNC blade grip to be fitted on my Trex. I am confused after going through its manual (small piece of printed paper)as it is stated that the trust bearing is located in between the normal radial bearings.

I fly nitro as well and there are some nitro helis where the trust bearing is fitted at the most outer portion of the spindle shaft. Knight 50's trust bearings are fitted at the most outer portion of the spindle shaft.

Are there any pros and cons, advantages and disadvantages of where the locations of the trust bearings are?

Thank you,

Larr

Just a difference in design. On the Raptors the thrust bearing is between the radial bearings, so we know it'll work there.

I've got a pair also, the centered thrust bearing is about the best design to eliminate the lateral torke/play on the axial assembly by spreading the roller bearings farther apart. The benefit is there is no pitch notching at high rpm, very smooth with zero coning.
