Swash Leveling Zip Tools Patent Pending

This tool allows you to level your swash plate WITHOUT removing the head. Polycarbonate tool won’t scratch your heli.


Press fit the tool onto the main shaft just over the swash plate and it provides a level surface to use as a reference while leveling your swash. Once the tool is installed, adjust the contact point to just touch anywhere on one swash linkage. You can then turn the shaft with the tool attached and use it to adjust the others to the exact same height. This tool is similar in concept to a zip tie, but it is easier to attach and remove and it has an adjustable contact point which allows for optimum accuracy.

Note: If the Polycarbonate tool can touch any of the swash linkage, you don’t need to use the adjustment screw.
Note: Measurement can be made to any convenient part of the swash linkage, not just the spot shown in my picture.
Note: Try using the head side of the screw if the holes don’t line with what you want to measure.
Note: Do not leave the tool in a flexed state on a main shaft when not in use.

Micro Servo 90 Degree Tool

This tool to makes it easy to align servo horns at 90 degrees on your micro size servos. With the shape of many horns, it’s difficult to eyeball it perfectly without the help of a tool. Lexan tool won’t scratch your paint.



This tool can be used on or off the heli, with or without linkages. Line up a slot with the horn holes then snug it down. Use sub-trim to line up the edge of the tool with the outside edge of the servo and you are done. It's similar to using a pitch gauge. Flip it over for servos with the horn on the other side. You may need a longer servo screw to mount. (not supplied)

Note: Peel protective paper off all Lexan before use (if there is any)
Note: Milling artifacts can be removed by scraping carefully along the edges with a fingernail, Exacto knife or 220 sand paper.

mCP X 3-n-1 Mount (for Controller Module)


This mount provides a light weight, vibration isolated, rigid mounting surface for your Flybarless 3-n-1 Control Unit.
Assure all servo wires are loose enough to move the 3-n-1 board forward at least an eighth of an inch. You may have to re-route the wires from your rear servo just a little. Assure all 3-n-1 connectors are glued in tightly. Slip the slots in the back side of the mount over the mounting tubes for the 3-n-1 board. Use the 3-n-1 stock mounting screws with a dab of CA on the threads to secure the mount to the tubes. Carefully place a square of medium thickness gyro mounting foam (not included) over the smooth side of the mount. Firmly and slowly squeeze the foam against the mount for about 10 seconds to get a solid bond. Carefully center and stick your 3-n-1 unit onto the new mount making sure the bottom of the 3-n-1 board lines up with the bottom of the mount to assure proper canopy fit above the board. Again, firmly and slowly squeeze the foam against the 3-n-1 for about 10 seconds to assure no gaps and a solid bond.

Note: Peel protective paper off all Lexan before use (if there is any)
Note: Milling artifacts can be removed by scraping carefully along the edges with a fingernail, Exacto knife or 220 sand paper.

Inverted Gyro Mount (The Thingy)

Its intent is to allow you to securely mount the gyro underneath the boom so as to avoid damage to the gyro by an out of control flybar or blade if you crash. Mounts are available for the TREX SE, XL, SA, SuperFrame, and Mini-Titan.


SE Inverted Mount XL Inverted Mount SuperFrame Mount SA Inverted Mount Mini-Titan Mount

There are 4 main approaches to mounting the Inverted Gyro Mount:
  1. Glue the Inverted Gyro Mount in place. (SA, SE, XL & SuperFrame mounts)
Use Plumbers Goop to secure. Adhere to as many surfaces as possible to give the best grip. Avoid getting goop on the boom since you will want to adjust it periodically.

  1. Screw it into the boom block through the bottom of the Inverted Gyro Mount. (SE mount only)
This method requires you to drill one hole through the boom block, and then tap the hole with a 3mm .50 pitch tap. Press the block into place and use it as a template to drill a #40 hole. Only drill through the first layer of metal which is only a few mm thick. Carefully tap the hole with a 3 mm .50 pitch tap. Use loctite on screw when installing. Make it snug but do not over tighten or you could break the bond between the inner block and the top block. You don’t want to strip the hole or damage the Inverted Gyro Mount.
I will drill the countersunk hole in the Inverted Gyro Mount and provide a 3mm stainless steel mounting screw if requested when ordering.

  1. Screw into the Inverted Gyro Mount from both sides through the frame. (SE & SuperFrame mounts )
This method requires you drill a hole through your frames on each side. Screws will go through your frames into the small block on the Inverted Gyro Mount. Drill the frames first. Locate the new holes directly between the two existing holes. Use a bit that matches the other holes in the frame.
Press the mount into place, and then use the frame holes to drill smaller holes into the small block on the mount. Use a bit sized appropriately for your screws. Drill very slowly making sure to keep the drill perpendicular to the frame. Drill a separate hole for each side, rather than one hole clear through the block.

  1. Stick on the Inverted Gyro Mount with double sided tape. (All mounts )
Use a thin 1/16”heavy duty double sided mounting tape like Scotch® Exterior Mounting Tape. Don’t use the 1/8” spongy type that comes with your gyro to mount the Gyro Mount because it will make the gyro response a bit mushy.

Whatever method you choose, be very careful that all is secure. A safety strap of some kind is recommended for added security. Losing a gyro mid flight will make for a very challenging landing and could be dangerous!

Note: Peel protective paper off all Lexan before use (if there is any)
Note: Edges can be sanded with 220 grit sand paper if the fit is too tight or if there are rough edges or burrs.
Note: If one clear edge is longer than the other, place the longer end out to make sure there is plenty of room to mount the gyro.
Note: Reverse the “Dir” switch on your gyro if moving it from the top to down under or spinning will occur.

Slotted Finless Fins & 3D Fins




Stop replacing those stock fins on the simplest crashes!
These fins are much more durable than the stock fins and they look great. They survive most crashes that would explode stock fins. They can however be scratched and they sometimes get stress cracks if tightened too much or during some crashes. Be sure to use SE bling or equivalent sized washers when screwing in or you can cause stress cracks. Do not over tighten, make snug and use Loctite. They are made of the same material as plastic eyeglass lens, so to keep them looking great, use care when handling. Wash carefully with water and pat dry rather than rubbing.

Note: Peel protective paper off all Lexan before use (if there is any)
Note: Edges can be sanded with 220 grit sand paper if there are burrs or they get marred
Note: Wash off any white powder or dirt with water, lightly dry with paper towel.
