We developed a new contra-rotating motor recently,we call it YX-13DZ (http://overskyrc.com/index.php?gOo=goods_details.dwt&goodsid=91&productname=) ,its real weight is 13g, I hope folks here can be interested in it, we could have make it smaller if we had found a smaller contra-rotating props :D companys can email us (www.overskyrc.com) for ordering samples.

Here are the technical details and the pictures:
Weight：13g
Diameter：13mm
Length：24mm （not including the shaft)
The hole diameter for fixing screws is 1.6mm, three holes are on a circle of 17mm in diameter.

Packs work with：1-2S
Props：GWS 5030*3 contra-rotating prop. The hole of the behind blade needs to be expanded to 5mm in diameter.

Idle current：0.1A *2 7.4V
Thrust：180g
On-load current：2.1A*2 7.4V

sorry, I don't know how to describe its sound when it is running at full throttle, need to find someone testing it on a right airplane.

Thanks!

Been planning a C130 Hercules for a while now. 4 of those could really add to the feeling i believe.

I guess it won't be so much from our dealers, the price on our site is for reference for retail, thanks for considerate.

Well, if you sell to the usual hongkong guys, the price will drop dramatically anyway, hard to find any normal dealer later...because price is bashed..
good for the customers, bad for local hobby shops..

hmm, I won't sell any our products to the hongkong guys, I know how hard the business of our dealers worldwide will be if I do so, thanks for reminding me. :D

This may be a dumb question, but... I can't say I've ever seen a C-130 with counter-rotating props...?

All the more reason to build one.

Yes, some dealer from Japan stocked it, but none from US or Europe, we are looking for dealers in the areas.

Thank you!
