VARIO 750 Bell 430 - Drive Options

The "small Bell 430" from VARIO is a 700, resp. 750 size scale helicopter. You can power this remote-controlled model helicopter with gasoline (benzin) or electric propulsion.

When it comes to performance, there are few helicopters that can match the full-size Bell 430. It is at the top of its class, often referred to as the flagship civilian helicopter in the range of Bell Helicopter. Compared with the Bell 230, it is equipped with a 4-blade head and, being 0.45 m longer, it has a new cockpit and cabin design.

For VARIO's 750 Bell 430, a maximum main rotor speed of 1350 rpm is recommended. Electric drive sets from VARIO are already tuned to this head speed.

Drive Types:

Benzin Mechanics

The benefit of a gasoline helicopter is a robust, easy-to-use engine for long flight times. The fuel is available at every petrol station (2-stroke mix). Kit Ord.No. 4300 contains the bulkheads for the gasoline mechanics. If the engine noise in flight does not disturb you, you will enjoy this classic drive system for model making.

Electric Mechanics 1002/82

Our propulsion recommendation for this helicopter! Contemporary mechanics, especially designed for the scale model electric flight. The mounting points in the fuselage are identical to those of the petrol engine. Electric motors are quiet, low in vibration, without exhaust gases, and residual thrust.

For this electromechanical system, you can choose between two drive sets: for 10S or 12S LiPos.

Electric conversion of the Benzin mechanics

Use kit Ord.No. 4300 for conversions of the petrol mechanics to electric motor drive. The strong and rigid aluminum side frames from the petrol mechanics are very suitable for the powerful electric motors being used in model helicopters today.

Electric motors provide very quiet operation with low vibration, and no exhaust gases or oily mess to clean up. Model flights are much more realistic without the noise of the petrol engine, and the electric drive is so quiet that even the sound of the rotor blades can be heard in flight.

Electric conversions are easy to accomplish using the suitable VARIO drive sets to achieve the optimum system speed for the 90:18 ratio. You may choose between 10S or 12S LiPo battery cells when selecting the conversion drive set that will be right for you.

Benzin propulsion option - Build suggestion

First, build a VARIO petrol trainer (Ord.No. 8311) in the pod and boom configuration and fly, later install the mechanics in your scale fuselage. Advantage: You buy the mechanics components at a reasonable price and can learn the flying characteristics of the Benzin Trainer.

The trainer mechanics can be built into all kits for gasoline mechanics or the electric mechanics Ord.No. 1002/80 and 1002/82. If you exchange the Benzin Trainer's 2-blade head to a multi-blade scale head, the reduction ratio must be adjusted. It is an easy conversion, and the VARIO support network is always available to assist with the change.
