I did also notice that after a crash sometimes one or more props will have been pushed down to far on motor shaft and rotation becomes restricted. This can be checked before each flight by simply moving throttle ahead enough to spin props and then quickly cut power. If a prop is dragging it will stop spinning much sooner than the other props, then with a small blade or screwdriver tip you can pry the prop up slightly to stop it dragging. Also, the motors can shift downwards in their holders after crash or hard landing so simply push up on the bottom and they will pop into place. This has to been done frequently.
I flew this off my patio and would let it go straight up until it was barely visible. This thing has good range and is remarkably stable in light to breezy conditions. I lost it the other day as I let it get to far away and lost orientation! I think it landed in a pine tree but have spent hours looking to no avail. Be careful where you fly it as this thing is tiny and hard to spot.
When I got this I think it was one of the best deals out there for a very stable and tiny craft but now there are better deals to be had out there in my book. I just got a new one slightly larger with built in video camera for less than $75 shipped. That's why I only gave 3 stars, because of current price just under $100.
Still a good choice for very small and durable flyer. I recommend getting a couple extra batteries and an extra charger, that way you can pretty much fly as much as you wan without having to wait for batteries to charge.
When I first started flying the 1SQ, I had a difficult time and ended up chasing it down between flights. This was clearly not the way to learn to fly the 1SQ. So I tied a 2 foot tether (braided nylon string tied to a wrench) around the + shaped plastic under the battery, and I was able to safely fly indoors while practicing the hover maneuver. Once I was used to flying the quad on the short leash, I let it out to 3 feet and eventually 4 feet (the longest I could go due to furniture/walls/ankles/etc.)
After I learned to hover the 1SQ on a tether, I started tethered landing (or trying to) on a manila envelope next to the wrench on the floor. That kept me occupied for a couple of days, but has been good practice.
All those tethered flights helped me when I finally went back outside on a mostly calm wind day. The 1SQ really flies nicely, and I'm looking forward to going back to the tether to learn how to do yawed turns, etc.
The Heli-Max 1SQ Quad-copter (RTF w/ 2.4 GHz radio) has been a great subject to learn to fly 3-axis quads. Even once I went off-tether, the copter is sturdy and resilient to damage on those less than controlled landing.
Battery life is adequate: depending on how aggressively the 1SQ is flown, it can stretch to 10 minute flights. Having a spare battery charging in the background makes it easy to keep going after the first flight. The USB adapter makes it easy to recharge, even out in a field (with the correct cable, off my tablet's USB port).
A few things to watch out for on this quad:
1. It has dual rates, but no expo. It's also easy to accidentally set the rates to 0 thereby neutering your ability to steer. My maiden voyage drifted straight into a wall.
2. Get extra props and batteries when you order, and be prepared to get extra arms/motors. It doesn't take too much prop damage before it affects how it flies. The prop shafts are also easily bent when you crash, making it even harder to control. The good news is that these are readily available parts on Amazon, but after a while it starts to add up.
3. It does not have an 'expert mode' for practicing rate or acro mode flying. If you try the flight controller will fight you.
4. Beware any wind. This thing is so small and light that it'll get blown away before you can do anything about it. When in doubt cut power and let it fall! Also the canopy is just a kite - take it off.
5. Yes, even though they're small these props will hurt if you fly into yourself or someone else.
While I feel like I did get my money's worth out of it, after replacing 6 arms and many props I decided it wasn't worth sinking any more money into. I built myself a ZMR250 clone and now that I have the reusable supplies I can put something bigger and more fun together for not much more than this guy. I mentioned the Nano QX because it is generally regarded as the best trainer for bigger quads - it's highly repairable, has a real expert mode, can bind to any DSMX transmitter, and you can even get better frames to transplant the guts to!
