I am installing the blue gears on the boom and tail. Does the small gear on the boom just press on? Is the hex end of the aluminum shaft for the gear which is retained with the set screw? Where does the small washer go? Thanks in advance.

The large gear (input) should have a set screw to secure to the hex tip, and the small tail (output) will probably need to be glued, unless you have one with a setscrew like some of the new ones coming out.

I hope I don't need to glue the pinion. It is really hard to fingd the correct adhesive with plastics. It IS a really tight fit. Anyone else have a blue gear without setscrew? What did you do? Thanks.

My blue gears came from Wes at Modefos, They are made by Micro helis. They do have set screw in input gear and the output gears pressed/glued on Have not heard of blue input gear that does not have set screw, were did it come from?

I got my gears from Wes also.......they are as you describe. The output gear is a press fit.

Sorry for the confusions,

There are three types of Blue gears

1. The Blue INPUT gears have a set screw.

This set screw will lock the gear onto the hex head of the shaft drive. Some customers feed back with difficulty to tighten the tiny set screw onto the hex head. Next generation Blue Input gear will not have a set screws and will sit on the Non Hex Head tail drive shaft that goes with the second generation Blue Input gear.

2. The Blue OUTPUT gears do not have a set screw

This gear is pre-glued onto the tail shaft. No set screws.

3. The Blue BEVEL gears
a. The small Blue BEVEL gear also has a set screws It is good to apply some glue on before pressing the gear into the end of the tail drive shaft. It locks very tight onto the carbon fiber tail drive shaft. Actually with some glue, the gear is already very tight on the carbon fiber shaft. The set screws is an extra to guarantee absolute no spinning.
b. The longer Blue BEVEL gear is pre-glued onto the high speed stainless steel tail shaft. It also has an aluminum shaft collar with a set screw to guarantee no spinning.

We do not make these gears anymore until 2005.

Hope that helps.

My blue output gear has no set screw and was a tight press fit onto the sparrow aluminum shaft. I guess I should take things apart and glue it? What type of glue would you recommend on aluminum? Thanks!

Skyup,

CA Glue. Apply some inside the gear first and some on the shaft. It will be fine.
