Designed and engineered for perfection.
No more messing with glues or adhesives.
High Quality CNC Construction.

The Viper Skeleton comes complete with the lower mechanics of the Viper CPX.
The kit comes will all of the necessary components needed to construct it ( See Picture below )/
All parts are CNC machined and are made in the USA.

The Skeleton Viper comes with a duct fan fin which is ready for the GWS 50 size duct fan. In future releases a 40 size duct fin will also become available !!!

The frame construction is far superior with many advances in Micro Heli design including an aluminum mounting servo arms which extends to each of the servos ( fwd / aft / roll and pitch ) and enable the servos to connect to the assembly using screws and nuts. Slots were added so each servo my be adjusted for a perfect slop free linkage setup ( A 90 degrees / even configuration ).
The mounting arms hook to the main assembly using a set screw on each side for a solid hold.
The lower and upper arms may be adjusted in distance from center so different servos may be used ( such as the Lexors, Hitec HS-55 and HS-50 and even HS-81 ). The main post rests inside the base using a pre machined cavity and two additional socket head screws hold the assembly together, this design gives the ultimate support and may be most noticeable when the machine revs up to very High RPM, the flyer will appreciate this design in construction as it prevents the machine from shacking or swinging at the root which is the case with many plastic frames.

The Base plate was threaded throughout its surface so additional accessories may be also added at a later time.

The base plate rear strut mount connects through slots giving the installer a more flexible adjustment and controlling the length between the struts.

The motor mounting hole uses a standard opening so you may use any of the commonly available electric motors such as the Hackers, Model Motors, Himax and Speed motors.

The frame was designed to be used with a Duct Fan such as the GWS EDF 40 which installs directly onto the supplied Delrin machined duct fin. The main rotor mechanics recommended for this Heli is the 3D Core. For the main gear we recommend using the 100T Machined white main gear and One Way bearing with CP Titanium Shaft.

For owners of the Piccolo CP and Piccolo Pro the frame will accept all of the main rotor mechanics and you may easily install / convert your CP / Piccolo Pro using this ViperHeli Skeleton frame. You may also order the separate CNC components and create your own custom machine. The frame was designed to be used with a Lithium battery pack and so the front battery pack mount will accept a 2/3/4 cell pack.

First begin by mounting the main post to the chassis / plate using the supplied screws and Allen key. Make sure the socket head faces the top side of the plate and the closing nuts lock on to the other side of the plate facing the ground. This will insure the main gear will spin freely without running into the assemly hardware.

Insert the main plate through the front and rear Delrin struts and lock both struts ( legs ) onto the aluminum base plate using the supplied screws. The front strut locks using two socket head screws and two nylon nuts on the bottom. The rear strut locks onto the base plate using a single screw. Note that a special through hole was machined to back strut to enable for easier installation.

Slide the skids thorough the strut skid opening. Lock the skids in place using the supplied silicone rings.
Note for additional strength you can apply lock tight to the skids in order to insure they will not rotate inside strut opening.

Now slide the two servo (3) arm mounts onto the main post. Make sure that arms are positioned in the same manner as in picture. Lock each arm onto main post using two set screws per servo arm mount. Note that you may adjust the distance between the upper and lower arm to accommodate for almost any micro servo size making this a very clean and adjustable setup.

Install the platinum boom through the back strut clamp and lock in place using the longest supplied screw and nylon nut. Mount ball ends to rear strut using the supplied nuts and connect CF rods / ball links. Measure distance of horizontal boom clamp mount and thread ball ends to the Delrin bracket. You may also want to tap the boom so the balls will run through the boom for stronger installation. Clamp CF rods / ball links to other end ( horizontal clamp ).
