Engine Preparation


Replace Throttle Linkage wtih Standard Zenoah RC Linage. Note that you will need a small cut on the RC Throttle linkage to lock spring


Stock spring loaded pull-start is really cool. it does not require any force to start the engine but, due to the size of this pull start, ground clearance is almost none.

If you want better ground clearance, you can change the stock pull-start with a after market conversion kit which will let you install standard pull start.


Conversion Steps Reference

Brief instructions for POWER 460 - very simple steps


Prepare Transmission

Note: open bearing side will face towards the clutch and pinion

Here's the upper transmission block

Here's how you will install the pinion bearing block. Easily adjust the backlash - remember, not too close and not to far from main gear. use a paper between pinion and main gear for best backlash setting

Once adjusted, mount the block with screws

Baseplate is in two identical parts - install it by removing the bottom screws from the engine

due to wider rear frames, you will need two new holes, just beside the stock location

Front frame mount

Rear frame mount blocks used from Trex600

Engine mounts right on the pinion block. Open-Source sits on the front frame mount on top of the engine

Strong concentric running transmission

Throttle plate mount location

Front frame sides

Rear frame sides

As mentioned above, replace stoc throttle linkage (left) with Zenoah RC throttle linkage (right). notice a small notch made on the throttle linkage for spring

replace stock throttle link with the one you prepared above

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.
