Designed from the ground-up by our own engineering team, the X900 Tricopter is a culmination of months of design, testing and material sourcing to provide you with the perfect mix of quality, performance and value. The X900 Tricopter frame is a Hobbyking exclusive meaning you won't find it anywhere else!
The X900 features a very nicely finished glass fiber main frame, shock-absorbing landing legs and folding aluminum arms. The shock-absorbing landing legs are a great feature to handle those rough landings that we all have from time to time.
The integrated tail servo mount is constructed of glass fiber as well, allowing you to mount your favorite micro/mini tail servo for yaw control. The rear motor mount pivots on a dual ball bearing supported shaft providing super smooth and precise movement. As a result, the yaw control is locked-in and very precise while flying.
We offer a full line of multi-rotor electronics such as multi-rotor control board, ESC, motors and more, so it has never been easier or more affordable to get your multi-rotor frame in the air!
All necessary hardware is included. Simply add your own electronics.

This is a great tricopter for the price. The only issue i had was the tilt mechanism. It isnt the best design right out of the box. ive stripped many high quality servos from mild landings. But the greatest solution is to buy the tough tilt mechanism from flitetest. with a little bit of cutting to make it fit properly, it is the best upgrade for this tricopter. I also got the battery and camera tray from flitetest and it fits perfect onto this with a little bit of drilling and is great for FPV.a good frame for an tricopter(just a few issue) much better than rotorbitssssThe tricopterframe is well made, but the tilt mechanism has too much play. When I tried to take off, the mechanism begins to vibrate so much, that it was impossible to fly. I tried 2 different servos but always the same :/.bought this as my first tricopter. price wise you cant beat it. for what you get it is very great. the only major problem is the tilt mechanism. the best way to fix it is to buy the tough tilt mechanism from flitetest. before i put that on i crashed a couple times and it always ruined my servo and bent the stock mechanism. but once i changed it it was perfect and everything else holds up as well. a little challenging to build too but with a little basic knowledge it comes together quite well.Sturdy folding frame with easy setup. Exploded diagram is helpful, but the best setup help is the video available walking you through it step by step.
The motor mounts are designed to break away in a crash, saving arms and motors.
Makes for a stable platformIMO this frame is passable and it comes with everything to be functional. BUT, the biggest issue is the motor mounts they break right away and the metal motor mount kit i found was 20 bux on amazon, no biggie, but they should have included them. Second issue is the hardware is not the best; its to long it some places, and to thinly placed in others (but still works). Third, they didn't include ANY anti vibration mechanisms like rubber washers to mount under the regular washers or rubber pieces to put between the motor mounts and frame or such. So with the extra motor mounts i bought that brought my cost with tax and shipping close to the price of the carbon fiber tricopter frame sold here on hobbyking. So, i should have just bought that one i guess. Live and learnI'm having trouble with the yaw mechanism. If I tighten the bolt that goes through the bearings, any more than finger tight, it becomes hard to turn the motor. Is this normal, or am I missing something?2 tricopters purchased: perfect
