@brian,

This is new to me?
I don't think they are?

They are manufactured in Korea or something.

Yes, they are. Sky-technology.net is registered by a person in Korea;

Yes, Korea... At least thats what the box mine came in says.

They do have an office in California somewhere for support though.

Yeah, and according to their site, horizon hobby is their exclusive US distributor.

untill a month ago you couldn't even get one there. Now they are exclusive...? You cant even get a decent motor to go with the controller from them. Why are they even bothering with the controller if they don't sell a motor to go with it. All they carry in the way of brushless motors is a bunch of airplane stuff, 1/18th and then the usual sensored stuff.

Money and big talk is the key...

Wow.. I didn't even realize that horrizonhobby has them... so I can get them from my local hobby shop here in canada... AWESOME!!!!

The tread is a little of course now isn´t it :-)

I have had my answers - thank you very much for the advises.

it all relates somehow..:)

I'll do the quark125 and 7xl also for a revo... I just gotta find a cheapo roller....

What would be a good gearing to start with, with a 7xl on 14 cells? Would having 4S2P allow you to gear higher or not so much?

with the 7xl, you shold not need to gear up high at all. If it were a 9xl, then yes, you may want to gear it up some.
