I am about to get a Duzi one-way Main Gear in the mail this week. Which pinion should I run? 11,12, or 13? I am running thunderpower 1320 pack with the axi MS 300/20 motor. Weighted MS blades with Bell hiller...etc. I like to do 3D.

I noticed that Duzi wraps his receiver in a material that looks like the space age aluminium wrap thats on the lipo packs....does anyone know what this material is and why he uses it?

Thanks!

probably foil tape, to stop interferance
You can get it from your local hardware store ask for foil tape for lagging (insulation)

I get a constant supply of that tape from raiding plantrooms at work

Not sure on the pinion proabbaly best to test all 3 and see which one you like the best

The middle one (12T) seems to work the best.
I think that this is also what Martin Duzi is flying.

he is flying 12 for hard flying 13, but your battery must be able to deliver the current for 13

DUZI spares
I have the Duzi AXI motor gear which is excellent. Only problem is that I cannot get spare pinions anywhere. Can anyone tell me where to get these, or a suitable alternative?

I assume this is the Duzi main gear with teeth on the inside? I tried this decided not to us it because the plastic upper heli frame flexed too much for my liking.

Since the pitch diamter of the Duzi gear is smaller than the stock gear, the force on the geartooth is higher, and this causes a higher side load, which bends the upper frame. I guess that the Duzi gear moved 2 or 3mm at full power.

Can you please tell us what you find?

I dont notice mine flexing...especially 2 or 3 mm....that sounds like something else is not right maybe?

I mean, please tell us if the flexing of the upper frame, when using the Duzi gear, is a concern.

Thks,
Jimmy

Duzi gear
I have no problem with the Duzi/AXI combination other than the dificulty getting replacement pinions. I have had a couple of 'arrivals' where the motor kept turning and the plastic gear did'nt - and melted. Better the little plastic gear than the metal main gear. I dont have a problem with flexing of the frame etc. In fact the pinion has more surface meshing area as it runs on the inside of the main gear.

I don't have any issue with flexing at all.
Is not the problem too tight gear mesh?
According to Martin, one should set the
mesh as small as possible (almost zero)
such that there is no significant force
keeping the wheel from spinning. Also,
the pinions are just stock 11T, 12T and 13T
with larger hole in it, so if you have
the equipment, you can make your pinions
from the stock ones.
