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

 

Helibug Open-Source, designed to use any power source using Gasbug Modules. Currently available with Gasbug-RC to use any Zenoah RC Engine as a power source
Here are some of the key points which makes this conversion kit different from others:
Designed for Zenoah RC Series Engines (G230RC to G290RC or CY Zenoah Clone Engines
Highly precise aluminum parts
All 3/16" (4.75mm) thick T6061 aluminum plates machined with very tight tolerances
Lighter then HB7-RC kit
Excellent Balance and Performance
No Vibrations at all, even with a stock engine
Engine can mount forward/backward without changing/adding any parts and can be done anytime by just rotating the Gasbug-RC below
Slots for pinion block makes this kit to use any gear ratio from stock 8.2 down to 4.1 (from 14T stock pinion upto 28T Pinion) without changing side frames
This kit uses all standard M3 screws (Included)

Less then 5oz (140-grams) heavier then HB7-RC kit but, since this kit uses smaller fuel tank, all up weight is lighter then HB7-RC kit
Total weight of all aluminum frame = 1.33 lb (21.4oz) 600 grams
(for reference, HB7-RC Frame weight = 1.02 lb/460 grams)

You will only need an extra pack HN7084 (Front Frame Mount

Also, coming soon, Gasbug Modules for few other, much more powerful Gasoline Engines along with a Gasbug-TURBINE

Conversion Step Reference

 

First, lets identify the parts, outlined parts below is Gasbug-RC Module. Two side frames is Helibug Open-Source

Just like our HB7-RC kit, start with installing the clutch mount on the engine

Next Step: Install Engine on the Baseplate

 

 

Top Engine Mount: Install two Front Frame Mounts from Align Trex700 onto Top Engine Mount Plates

 

Install Top Engine Mount Plate on the Engine with included screws

 

These parts are Engine Cage, Use two frame mounts as pictured below with included screws

 

In this step, you need to mount the Engine cage on Top Engine Mount Plates, but, keep the screws loose...It will give you exact location for the bottom side of engine cage to go on the baseplate. The top screws is temporary and will be removed once Engine cage is mounted on the baseplate

 

Once you got the location, use thread locker on these screws

 

Remove temporary screws after mounting Engine cage on the Baseplate

 

Helibug Open-Source Side Frames 

 

Procedure to build side frames is same as Trex700 (follow Trex700 manual)

 

Note: do not use Align Trex700 spacer on Elevator Shaft. Side frames are milled to keep cyclic links clear

 

Helibug Open-Source Side Frame with Gasbug-RC Link Plate

 

This is the location to mount Gasbug-RC Link Plate. Use included screws to mount this plate on Open-Source

 

Two screws with nut (included) at the back on each side of Gasbug-RC Link

 

Note: Adjustable slots for Gear ratio used. Once you mount the pinion, Gasbug-RC will mount to correct location according to the gear ratio used

 

You can mount Gasbug-RC as Engine facing backwards or Forward. In any case, use Tailboom brace location is mentioned below in the picture. Optional spacer can be used on the location mentioned below

 

Throttle Servo Location

 

 

 

 

 

 

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.
