Bad ESC came with my kit. They won't believe me, want more and more proof.

I've been flying for about 10 years, been flying 450 size, this was a step up. it was a fun build, everything fit together great good quiaity. I'm a sport flyer not much 3d. I can get 16 minutes flight time on 2800 6 cell, the thing is a beast and with the blue tooth app you can tune it in the field easy. would recomend

After 23 years since I last flew helicopters, I bought the S2 max to see if u wanted to get back into helis again. Well I got hooked all over again but since I’m old now it was a little small for me to see so I upgraded to the RS4 combo and I am blown away at the quality. UPS delivered it a 5:30 pm and a 2:30am the next morning it was ready to fly. The stabilization mode made it super easy to learn again how to fly these machines. I’ve progressed to the stunt mode now and loving it. So glad I made this choice of Goosky

Great heli for a first build!!

Goosky hit the nail on the head with this one for the simple fact that its extremely high quality and comes with everything (exception being your choice of receiver). The GTS FBL w/ app is great and allows you to really dial it it. They REALLY need to take this formula and apply it to the RS5, 6, etc. The instructions are clear, the build was super smooth and fast, all rotating parts are super smooth with the provide shims, it looks great and I could go on. The hover is rock solid, I mean hands off rock solid. Take your time building, use a level when needed, be meticulous and you'll have a machine that is Cadillac smooth.

Package arrived as expected and well protected. The quality of this kit was excellent. Instructions were very clear and nothing was missing. Worth noting, this was my very first helicopter build. Started with the S1, then S2, and now this kit. Goosky makes amazing products and Helidirect is an awesome source for anything Rc related.

RS-4, Awesome heli, great quality, easey to build. This would be my second one.

I'm relatively new to this hobby - bought a Goosky S1 about 4 months ago, then bought an S2 about 3 months ago, then decided to move up to the RS4 (slippery slope!). The RS4 build was straight forward and there are lots of quality youtube videos out there to guide you if you have questions. I chose this version of the kit because all of the electronics are included (except for satellite receiver to bind to your radio) and as this was my first-ever heli build I didn't want to have to worry about researching/selecting electronics. I've flow about a dozen batteries through it now and this thing is amazing! Way different and more rewarding experience vs flying the S2. I highly recommend this kit as a step in the natural progression up the heli size chart.
