What do they weigh? Does each gearbox come in one gear ratio only or do you get three pinions with the box so you can change to the other ratios yourself?

You'd probably be better off posting this in For Sale / Wanted.

Thx, Pete

The price was $29.90 in your other post, or was that a different gearbox? if so what are the differences?

Gearbox

Old Velkom stock only couple of them left for 29.90$ (10-15). At that time I did not have this information. The new ones are for 36.90$

Funny, I just bought one of those gearboxes (3:1 ratio). It weighs 98g (3.45oz). Okay, not all of the srecws are needed, but 1.5oz? Never.

Frank B,

thanks for that post! I got mine a little while back and remember being surprised how heavy it was, but I couldn't figure out why I thought it was going to be lots lighter - now I remember - this thread

2 oz in 40 odd would not be that big a deal, except when its right on the darn firewall!! At least it looks solid and the ratios are fairly easily swapped.

The old ones were 2.5 oz (not 1.5 oz).
.
The ones in the picture at the top for Jeti have an extra half moon shaped piece which presumably adds another ounce.

I'm flying one of these gearboxes already.
Like the one in the very first pictures in the thread.
Good heavy duty gearbox...I'm using the 2.5:1 ratio
on a Phasor 30-3 pulling a 18.5 X 12 prop on a
107" motor glider at 61 oz using a 10 cells 2000 mah pack.

The gearbox works great, but you better loctite the screws.
And there are more screws in the kit than I needed for the
Jeti. It seems to be a gearbox for many different mountings.
It is beefy and probably weighs the 4 oz or so. But I'm not
going to take it out of the glider to weigh it, sorry. It needs to be
strong and a bit heavy to handle these kind of prop sizes.

Mine says it's manufactured by Model Motors in Czech Republic.

The actual measured draw on static is 16 amps and 3100 rpm.
Probably should have used the 2:1 ratio but I don't have that
one.

Jay

Jay,

What ESC are you using? Is the GB holding up to the brake? Lost a Mega 1.8:1 box. I am new to brushless. In my brushed (Astro FAI 40G) days, I would use a soft start/ brake esc. I have not noticed this feature in brushless esc's. I am using a Jeti 70-3p opto. Just wondering if the brake ate my pinion or will do so also with a Esprit 2:1 GB. Thanks for any info.
