Helibug Mercury 800 HB8-RC Gasser Conversion Kit for Trex 700

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





This conversion kit is also compatible with all Helical gear upgrades from Align including

 112T Helical Main gear with 14T Helical Pinion


Ships with 'Revison 1' Side Frames

Revised side frame design does not require tail servo on tail boom. Tail servo goes on the side frame as on stock 700 frames

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 !

Conversion Step Reference


There is nothing special in converting Trex 700 to Helibug Mercury 800 with this conversion kit. The only addition from the manual is mounting the RC Engine. Below is the step-by-step pictures as installation instructions. Please also look at the pictures on HB7-RC Page for reference.

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.


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.
