HB7-RC Gasser Conversion Kit for Trex 700

Designed to convert Trex 700 Nitro into a Gasser Helicopter using Zenoah RC Series of Engines

All up weight = 11.6 lbs with stock Zenoah Muffler

 

This Conversion kit is compatible with all new Trex700 T/R Helical/Slant Gears

Now also available with 16T Helical Pinion

 

  

Align Trex700 Clutch bell with Blue Liner

The new clutch bell from Align with a 'blue' clutch bell liner is the best upgrade from Align. This clutch bell uses thicker clutch liner. It has a much better gap between the original Trex700 Nitro Clutch and the Clutch Bell.

I highly recommend using Align Trex700 Clutch with the NEW Align Trex700 Clutch bell

There is no need to upgrade to Lynx Gas Clutch as original the "Gap" with the older Align Clutch bell was unacceptable for gasser performance. Also, there is no need to fix any tolerances for the Trex700 clutch to fit into the bell as it is factory adjusted for the best performance.

100% compatibilty with the Trex700, flyers can benefit from not only Lynx Gas Clutch, but, also QuickUK standard and HD clutches along with the Lynx stock Trex700 Clutch.  More choices of clutches to choose from !

This applies to All Helibug Gas Connversion Kits which uses Original Trex700 Mechanics

Choosing the right Pinion (Gear ratio) for your Flying Style

This is the most common question we receive from Buyers...."Which Pinion should I buy?"
Here is a brief selection criteria you should use when buying this kit.

16T Pinion (7.18 Gear Ratio)
16T Pinion is best for sports/mild 3D flying, so if you are a sports/mild 3D flying, it is highly recommended to use this gear ratio.

17T Pinion (6.76 Gear Ratio)
17T pinion is best for sports and a good level of 3D flying. so, if you are a 3D pilot/sports flyer, this gear ratio is best for you.

20T Pinion (5.75 Gear Ratio)
20T is only made for Extreme 3D Pilots. Although you can fly sports with 20T pinion but, its not recommended to use this gear ratio for sports flying.

Please note, if you plan to use a Modified RC Engine, than its highly recommended to use 16T Pinion (7.18 Gear Ratio)
My personal recommendation is to use 17T Pinion for all flying styles !

There is nothing special in converting Trex700 with this conversion kit. The only addition from the manual is mounting of Zenoah Engine. Below is the step-by-step pictures as installation instructions

WARNING: The radio controlled model helicopter built from this conversion kit is not a toy and is not meant for children. It is a flying machine capable of causing property damage and serious bodily harm to both the operator/assembler and/or spectator if not built and operated correctly and responsibly. Rotating components, especially the main rotor blades, are an ever-present danger. Model helicopters operate differently than model cars and airplanes. Helicopters by their nature are not positively stable, meaning that even if properly assembled and adjusted, helicopters will not recover from an unwanted flight attitude, nor will they hold any particular orientation without constant control inputs from the pilot.

IT IS YOUR EXCLUSIVE RESPONSIBILITY TO PROPERLY BUILD, MAINTAIN AND OPERATE HELICOPTER.

HELIBUG has spent considerable time making this product reliable and easy to build, but only the operator can insure that it is safe. Because the safe operation of this helicopter is beyond the control of the Manufacturer and distributor, the owner/operator assumes all risk of use.
