QR-1 and Hubsan X4

Yes, I realize that they are virtually identical...

With that in mind, if the Hubsan can be had for ~$52 (shipped from china - including a spare battery, plus spare blades)...and the QR-1 can be had for $70 (USA - includes xtra battery, extra blades)...is the QR-1 worth $18 for the differences (US warranty support, dual charger, availability of parts)?



Thanks,
Bombay

Thats a question only you can answer. To some people $18 is a lot of money, to others it isn't. They are the same mechanically so just weigh out the other slight differences.

Ayo,
Those are through hole vias for the crystal so although only the bottom has solder, it is OK. Use hot melt glue or some silicone glue(my preference) to adhere the body of the crystal to the top of the IC that they have it over.
Cheers,

When you say hot glue the crystal to the fc, do you mean I should put glue on the points where it's soldered to, or glue it to the black square sensor it's on top of?

Sorry Im clueless when it comes to this stuff...hence the question !

My motor wires are not twisted. I think it might help if your motor wires are too long but otherwise I don't see an advantage in having them this way.

Hi guys I just received my x4 being my first quadcopter purchase and I am very impressed.
I have little to no prior experience with flying gadgets and only ever played with nitro cars. I was flying within 30 seconds of taking it out of the box, as you can imagine from a newbie like myself who didn't read any of the manual I crashed it within 15 seconds lol.
It's surprisingly tough for its size and I haven't done any major damage yet, apart from bending/curling the ends of the props ever so slightly in. Hopefully I can smooth them back out while I wait for 20 spare props to arrive

All in I'm very pleased and can't wait to get home to fly it some more!

Try pushing hard on top of the motor shaft? In the help index there's more detailed info, basically just put your index finger on the bottom of the motor and thumb on top then push hard!

Hi S,
You likely used the motors as landing gear and pushed the bottom of the motor out a bit, so you wan to pull, not push on the motor shaft. See the video M linked above http://www.rcgroups.com/forums/showp...postcount=1677 Then if you do get them working or replace be sure to also do the straw motor protection mod that MassiveOverkill suggests: Micro motor saver guards
Cheers,
Jim

You can replace them with Ladybird props (I would change them all at once) and those can be found at most local hobby stores.

I don't like Quad, I will never Like Quadcopter...They Don't realistic scale like heli or airplane...the shape of quads really untidy, wire got in the way, Not Beauty at all. That was what I think about Quad, until Hubsan X4 Bite me when I bought it from my LHS for less than US$ 39. ....WOW!! This thing is awesome man Sleek smooth body shape, Simple, Tiny yet fly like on its rail, Very Durable (Crash it and drown in sewer, drying it with hair dryer and fly again ). I just never get bored to get it fly.
