content: I just flew my first RC flying object --- a Hubsan Q4. Love it.(For anyone looking for quadcopters with brushless motors you don't need to replace after every 2 - 20 hours of flying, my few weeks of research will tell you not to. The smallest brushless motor now is the1306 3100kV, which will still cause flesh wounds easily. The Hubsan Q4 does not injure at all, and the X4 barely scratches your skin. That is also also why I'm coming back to considering learning to solder! I don't fly outdoors.)What is the best (not minimum) equipment I need to give me an easy time soldering new motors to my Hubsan Q4's and X4's?Note the really tiny size of the Q4...I need an easy time soldering new motors to my quadcopters. Why? Given a choice, I would solder nothing. :-P I am still desperately looking for Ready-To-Fly (not DIY) quadcopters that don't require motor replacements or any soldering at all.I'm not even sure if I need to actually solder. Seems more like simply melting the existing solder joints and attaching new motors to those joints.

Depending on the solder and flux already used, it might not need additional solder, but still good to have.For something that small, a temperature-controlled iron can be set to a specific lower temperature with less risk of melting the plastic frame or insulation on the wires. "Best" depends on the budget. The Hakko FX888D is a popular good-quality temperature-controlled station for around $100. There are cheaper temperature-controlled stations, and with how small those wires and pads are, it probably does not require much. There are cheaper stations for $50 or less. The Aoyue 2900 that has disappointed me for several years would have no problem with it.

content: 'Melting the existing solder joints and attaching new motors to those joints' seems about right. I removed a dead motor from a similar nano quadcopter (Cheerson CX-10) a few months ago and it was practically like this. Just be careful not to pull the pads by being too rough and a temperature-controlled iron like the one wblock suggested would be excellent for the job.Magnifying equipment might help as well, but I wouldn't say it would be essential.

content: Jup, those are fakes. They tell you that in the description: "High QualityCopyModel...." ect.If you want a cheap soldering station at least get one that isn't a fake.http://www.hobbyking.com/hobbyking/store/__19240__Soldering_Station_with_Adjustable_Heat_Range_US_Warehouse_.htmlThose use probably the same handpiece as the fake 888 but much much cheaper.Greetings

content: Soldering turns out to be 90% skill and 10% equipment requirements. I visited a "electronic tech school" in Mexico that were making equipment using soldering irons that resembled hotdogs with a point and were heated using no temperature regulation at all, yet the skillful students were able to make beautifully soldered equipment and repairs. They were even working on and replacing SMD parts in their Walkmans just using a cigarette lighter to heat the soldering tool, which in this case was just thebent-out metal pocket clamp on a ballpoint pen.Buy the cheapest thing you can find since you are only using it occasionally and spend a few minutes practicing your soldering.If you have money to burn, then consider an Hakko, otherwise consider HACK-OH.

content: For 20 bucks you can't go wrong with the 936 clones like the one linked above.Good tools are nice to have but you reeeally don't need a >$100 station if you're doing an average of 4 solder joints a week, if that. I started out with a 936 clone and I don't regret it one bit, just make sure you pick up some good quality leaded solder and you'll be golden.

content: I am surprised they dont connect via JST or spade plugs. Is it just to reduce cost?Are the motors prone to fail, or just abuse/accident.

content: Quote from: nowlan on October 12, 2015, 11:19:56 amPersonally, I think it's a combination of size/weight and price. These nano quadcopters are pretty small - palm sizeThe motors from my quadcopter failed from abuse/accidents - they can get jammed (occasionally overrevving the motor and destroying it), or exposed to large shocks (especially without prop guards). According to the initial post, they are also prone to failure, so it's a mixture of both.Heat is apparently also a problem with these motors.
