I'm looking for a "High Quality" gearbox for Aveox 36/24/2

Hi Folks,

I have an Aveox 36/24/2 motor (5mm shaft) and need a top of the line gearbox. The setup will be used in a Great Planes F-14 IC plane which I'm going to convert to E-power. Will definitely be using 12-16 GP 3300 cells (600-700 watts or more).

I never owned, nor operated a gearbox setup and would prefer a very high quailty unit (inline if possible). I'm not concerned about the cost, its all an invest for future planes.

Any help would be greatly appreciated.

Bob.


How about this unit?

Hi HD,

They only carry gearboxes with 1/8 pinions. The 36xxxx series are 5mm.

FYI, the flydma site has incorrect information of its Aveox listing for the 36xxxx series. They show the 36xxx with 1/8 shafts, as this should be 5mm.

Thanks though.

Bob.

these are great gear-drives. They are very flexible in that you can fit just about any motor (including an outrunner) in them with a wide range of easy to change gear ratios.
I think that the MiniDemon can take up to about a B40 size brushless while the InnerDemon can hold up to two B50 size motors.

Ask Kirk for an Astro Superbox with pinion for 5mm shaft. Robust, helical gears ... high quality.

My vote is for the MEC super box or monster box, depending on the ratio you need and how big a prop you want to turn.

The biggest advantage of these is that its easy to change ratios as needed.

Try www.flydma.com and order one of the Aveox planatary gear boxes that are made for your motor.

The planatary gearboxes are sealed and will not allow any dirt to get in like the Astro or Model Electronics gearboxes will.

aveox must sell a planetary gearbox. I bought one form them for my... ah... what was it.. oh yah, 1412/2y. super boxes seem nice, but I'm always afraid when a gear is visible. its ok for say a speed 400 motor, but anything large, I just get nervous something may hit the gear.

I'm running a super box with a Mega 22/45/3 at 480 watts, 16x10 prop. Same motor in a 12 pound bipe and a monster box at 900+ watts, 22x10 prop. No problems. Thats a bit more than a speed 400

If you have a prop strike it strips the spur gear but the box is undamaged. The gears are easy to change out.

Like I said before, the biggest advantage is being able to easily change ratios to dial in a plane/motor combo. I have 4 or 5 pinions and several spurs on hand. I can do ratios fron 2.5 up to 7+ to 1. You can pop the motor out of one plane that needs thrust and into another that needs speed.

I like them, but they aren't rite for every application.

The changing the gear ratio does sound nice. Don't you ever worry about any bit of gunk jamming the gearbox? I guess it is pretty strong. I just like to have everything sealed. 900watts? oh come on! even I can pull 900watts out of a speed 400!. maybe only for 1/100 of a second before it ignites in a ball of flames..

Thank you all for your comments and suggestions. Very much appreciated.

After reading everthing, here are the two units that would work:
Both are list here:http://www.flydma.com/gearbox/36_gea...ath2=zoom4006v

Astro 702 gearbox 2:38 to 1 ratio for $34.95

or

Aveox 3.7 to 1 ratio for $94.95


I need a low geared setup using a max size 13"prop and needs to handle continuous high power.

Which one guys?

Bob.

Bob,
You can use an Astro Flight #712 Superbox (05/15 size) which has a 48 tooth spur gear. Put on a 13T pinion (for 5mm motor shaft) and you get a 3.69:1 ratio.

Look at Northeast Sailplane Products. I just bought a Promaxx SP 3.3:1 metal planetary type. $64.
