Product Listing Update: Received a number of emails in regards to discontinuation of few gasser models. We have re-listed few of the models back to our active line of available products. Available under "Older Gassers" on the Product menu.

Please feel free to order as required.




Dear Flyers,

2018 onwards, we will be discontinuing a number of gasser
conversion kits.

Please note that the replacement parts availability on all discontinued products are on
the basis of â€˜first come first’ as we have a very limited
replacement parts stock.

We will be releasing few new gasser conversion kits for
newer models with additional choices of Engines including Saito
4-Stroke Gas Engines.

Thank you again for your support !


Beware: Using Zenoah Clutch in R/C Helicopter

Zenoah clutch is designed for lawn mower equipment.

This clutch is NOT newbie friendly at all. Must only be used by Expert R/C Helicopter Pilots

It produces much higher frequency vibrations in r/c helicopter resulting in the most unpredictable crashes of your r/c helicopter.

Here is the checklist of what you may face:

1. Overheating clutch bell due to clutch slippage (check your clutch bell temperature after landing)

2. Higher vibrations causing parts to fell off during flights

3. Breaking/loosing links

4. Reduced life of Servo/Servo failure

5. Breaking Servo Horns

6. Slipping/Damaging Bearings

7. Over heating bearings/transmission components

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
