What is the difference?

I was looking at getting some part for my trex 450 I think its a pro v2 ?

I came across two different tail hubs

1st

2nd https://www.amainhobbies.com/align-a...t003xx/p252439


could I use the 2nd one? I have the 1st one there right now but the grip slips off maybe due to bad bearing tho

The first one uses the standard tail grips and the second one uses the upgraded blade grips with the thrust bearing.

This is the upgraded tail assembly

The hubs are not interchangeable, but you can change over to the upgrade assembly


Here is the Tarot example of the thrust grip. It is the ones I use.

IMHO, change over it is a better setup.

Thanks for the quick reply. I had no idea the first ones only used radial bearing and no thrust.

I'll be pulling some stuff apart tonight to see.

the same size shaft can be used correct? mine is TT tail.


Thanks again

Yes the shaft is the same.

Make the change, it is a much better setup.
