› Swift 16 scale mechanics - why two main gears?

I'm building a Century 30 size Jet Ranger that came with Swift 16 scale mechanics. The package didn't come with any instructions so I downloaded the Swift instructions from Century's web page. The instructions I downloaded shows just one main gear but mine has two. They both look the same but one has the one-way bearing hub and the other just has a straight bolt through hub. Not sure why both are used other then the only thing I can think of is they are needed to handle the torque of the electric motor. But for this to be the reason, I need to use the "long" type pinion gear so it will come in contact with both gears.....which I can only get it to around 80% contact with the second gear. So am I missing something here or am I setting it up the correct way? Thanks! Mark

your motor pinion will contact the top main gear in the front and the bottom gear will contact the belt gear in the rear.


Also here's Century's repository for its manuals

Hope this helps....

Thanks simages but I believe my tail is driven from the top gear and not the bottom. I'll have to check it when I get home tonight.

I have 2 sets of the Swift scale mechanics and both came with only one gear. The motor pinion meshes with it in the front, the tail drive gear meshes with it in the back.

This is the manual I am using:

I assume he downloaded the Swift 16 like yours however; hrc37 says that the manual, shows just "one main gear but mine has two."
So, its either been modified or its an NX airframe.

HRC37.... pictures would help

Ok guys, I checked my setup again and simages is correct....the pinion rides on the top gear and the tail drive rides on the bottom gear. I apparently wasn't paying attention the other night when I test fitted the tail drive/tail boom and didn't realize that I had it upside down which causes the tail drive to ride the top gear...and this is what was shown on the instructions I was using which is for the single main gear version. It all makes complete sense now...lol
Thanks to everyone for all the help! Mark
