***READ UPDATE AT BOTTOM***
Well, I've finally stopped flying this thing long enough to write a review. Before I get into it, I am just the average RC flyer, driver, Joe Schmoe consumer. I have put together some car kits, a few airplane ARFs, T-Rex helicopter kits, and some other stuff I can't think of, but I've also bought and enjoyed tons of RTR cars, BNF planes and BNF helicopters. I know enough technical stuff to get me around in the RC hobbies I enjoy, but I am not so technical that I come up with my own programming or alter opensource software of any kind.
As I have kept hearing all the buzz about 250 size racing quadcopters for the last year or so, I had been pretty much staying on the sidelines. Finally, a few weeks ago, I decided I needed to be a part of it. I started doing my research as I always do, and every time I read something that almost made me pull the trigger, I'd read a forum somewhere talking about the difficulty of building and setting up a 250 size kit. I asked a few local guys that are really into quads and FPV, but the answers I got sounded like greek to me. I found some RTF 250 quads, but the sticker shock told me to keep looking around. Finally, I read about some highly anticipated 250 quadcopter, the Spedix S250. I checked it out and was pleasantly surprised to see that the kit version was about $159 and the BNF version was only $20 more. Blade's 200qx isn't even this cheap! I was tempted to get the kit version, but I was so anxious to get flying that I finally decided to go with the BNF. They offer two BNF S250s, one with the KK2 flight controller, and the other with the CC3D flight controller. I did a little research, and also popped a note to some FPV friends telling them what I wanted to do with the quad, and how I was relatively new to flight controllers. They recommended the KK2 version and I trusted their advice.
After a couple days, I got my Spedix S250 and opened it up as soon as I walked inside my house. I was so impressed with how strong it felt and how sleek it looked with the carbon fiber and solid arms. As I charged my 3s 1800mah batts up, I put the props on, got a few spare straps out and put them on the quad. There was no manual or cheat sheet for programming the quad, but I had remembered seeing a link to an RCGroups thread at the bottom of the product page. I will save you the time in finding the settings I used and post them here:
Programming is straight forward with the 4 buttons on the flight controller. The frame allows you to clearly see the KK2 screen and also allows plenty of room to slide your fingers in to press the buttons. When I finished binding and programming, I couldn't believe I was done (for binding procedure, go here. Not even my Blade 350QX set up this quickly. These settings are pretty solid and provide both a decent amount of stability, but also a fair amount of agility to allow you to shoot your S250 through the air pretty quickly. They also allow you to stop that speed run pretty quickly and getting back into a stable hover. For fear of thrashing my new found flying buddy, I have not messed with any settings, and I honestly don't think I ever will. Also, I chose to attach my battery to the bottom of the quad instead of the the top. My thought there is that I'd prefer the weight lower on the quad, and frankly, it just looks better there.
Flying this little bad boy has been a blast. I started a little slowly at first just to get the hang of it, but once I got the feel for the S250's flight characteristics, I started whipping it back and forth as fast as I could. After a couple days of flying a few packs a day, I decided to hook up my FPV equipment. There is plenty of room to attach your equipment on the outside of the frame, but I wanted it inside with everything else. The front has plenty of room for the camera (attached with the included mounting plate), and the rear has plenty of room for your FPV transmitter and power input. I have only FPVed it a few times, but I have had great fun doing so. Prior to this, my only other FPV experience was with the Blade Nano QX FPV. It was nice to slice through the wind with authority instead of being bounced around with the slightest breeze. I am anxious to take the S250 to my flying field to really open it up. One thing I have noticed since I got this bad boy... my other quads and helicopters are getting nervous and feeling neglected. I honestly don't see any good reason to fly any other quad except for this one. It is not very often that I love a product so much that I want to encourage everyone to go get one, but, you know what? If you don't nab one of these, you are really missing out. Not only that, with the price point on the Spedix S250, you really can't go wrong. Use the money you save for extra batteries or for your FPV equipment. I don't know how these are being offered at such a lower pricepoint than the competition, but you're going to be impressed with what you get for this price. I have taken it to my local hobbyshop and ran into a few guys that had other 250 sized quads. They were curious as to what I had and were amazed when they found out it was the Spedix S250. They had never seen one in person, and after seeing mine, they regretted they had spent so much on theirs. I must say, that's a good feeling. So, that said, watch my videos below, then head over to your local hobby shop or online retailer and grab one of these! If you have any questions, feel free to contact me at email@example.com.
As I continued flying my S250, I noticed that on occasion, I was getting a drop in power and losing altittude. It happened a few times from low altitude and finally, on an FPV flight over a wooded area, I had the power drop and lost the quad in the trees, never to be found again. I started reading the forums and saw that a lot of other people were having the same issue. It doesn't appear that there is a fix from Spedix, but everyone's testing is proving that switching to a 6 ch receiver instead of just the satellite solves the issue. So before flying, or at least before flying far away or high altitudes, you might want to switch out the satellite to a 6ch receiver.
