alach Motors VM R5-420
- Sensational smooth running and high torque
- Spontaneous throttle response and smooth mid-range transition
The Valach Motors VM R5-420 just looks like a real radial engine, only smaller, above all it sounds like a real aero radial engine. Not improperly smooth, like smaller radials. If you have experienced our Aichi Val on an air show you will know what I mean. The absolute scale flight with the marvellous sound from that large capacity radial engine can, if at all possible, only be bettered with a full-size machine.

The big capacity per cylinder, the valve timing and the supplied ring shaped silencer are responsible for the realistic sound on idle and on part load. Like all Valach engines, the response to the throttle being opened is so smooth without the slightest attempt to surge.
Valves and their seats are manufactured by Honda, ensuring a very high quality. Due to the inclined valves, the combustion chamber is shaped more like a hemisphere. This improves the combustion and the engine has a higher performance. In addition the fuel consumption is lower than otherwise. My Aichi has just a 1.5 Liter fuel tank!

The crankcase, cylinders and cylinder heads are cast like with full-size aero engines, which enables a light weight and the VM R5-420 with the casting surface finish has a very realistic appearance. Due to the steel cylinder liners this engine will have a long life.
• Honda Valves
• Walbro Carburetor
• Valach microprocessor controlled ignition with auto advance and retard
• An ignition integrated voltage converter allows the use of two LiPo cells
• VM-Motors are designed using the latest tools and techniques
• Rapid spares delivery and repair service from Australia by Teamaustars.

Due to the rather pungent smell of normal grades of petrol and the alcohol content, we recommend to use either Aral Ultimate 102 or Shell V-Power in conjunction with the synthetic two stroke oil Valvoline SynPower 2T.

Like on the VM 120 B2-4T, the valve train of the new VM 170 B2-4T Mk.2 is fully encapsulated, improving rocker arm lubrication and the valve train runs quieter. The crankcase of the VM 170 B2-4T Mk.2 is manufactured from solid aluminum and guarantees highest strength with a low weight. The Valach engines VM 170B2-4T Mk.2 looks just like an original aero engine, only smaller, it runs smoothly like an original aero engine and above all it sounds like an original aero engine. Due to being a four stroke, the low vibration is nothing but sensational, and torque is really high. The response to the throttle being opened is so smooth without the slightest attempt to surge, making the Valach VM 170B2-4T Mk.2 absolutely ideal for your big aerobatic model. Being a four stroke with a large capacity produces a very realistic full-size aircraft sound. With a relatively small silencer the sound level is very low rather like a small saloon car. The Valach VM 170B2-4T Mk.2 is a four stroke OHV engine running on petrol/oil mixture. Valves and their seats are manufactured by Honda, ensuring a very high quality. The totally enclosed valve train reduces sound, as well as ensuring the rocker arms are well lubricated. Due to the steel cylinder liners this engine will have a long life. Rear view of the new VM 170 B2-4T Mk.2. Both intake tubes are exactly the same length. The recommended static RPM range for the VM 170B2-4T Mk.2 on the ground is 4,500–5,000. On the VM 170B2-4T installed in the Pitts Special S1-S, we use the Fiala 34x12" prop as this has proven to be ideal. Immediately after landing, that means with a hot engine, 28.5 kp static thrust was measured. When winds are strong I change over to a 34x14" Fiala. As would be expected the ground speed is increased, unfortunately the "Pitts sound" is partly lost thereby. The Fiala propellers are very efficient, this being due to minimal blade thickness. They sound especially good on four stroke engines. The processor controlled ignition allows easy starting and a exceptionally smooth running in all throttle settings. We had tried many oils, but recommend Valvoline SynPower 2T oil. Our BEL-RAY H1R, although excellent for two strokes, is not ideal for four strokes, as it burns very well without deposit and not much gets past the piston, as is the case by the Valvoline SynPower 2T. We recommend Aral Ultimate 102, as the smell is not so penetrating and it can be stored without deteriorating. It does not contain ethanol. The fuel consumption is approximately 50% compared to that of a two-stroke engine with the same displacement. A 750cc fuel tank lasts for about 15-20 minutes of flying time. The legendary perfectionist Henry Royce of Rolls Royce always insisted that an engineering construction to be right must look right. I defy anyone to tell me the Valach Twin does not look right.

Like on the VM 120 B2-4T, the valve train of the new VM 210 B2-4T Mk.2 is fully encapsulated, improving rocker arm lubrication and the valve train runs quieter. The crankcase of the VM 210 B2-4T Mk.2 is manufactured from solid aluminum and guarantees highest strength with a low weight.

The VM 210 B2-4T has been projected together with the VM 170 B2-4T, sharing the same crankcase, pistons and cylinder heads. A new, longer stroke crankshaft, longer cylinders and new steel connecting rods are responsible for the increased stroke, more torque and significantly more power output.

Just like the VM 170 B2-4T Mk.2 the VM 210 B2-4T Mk.2 is an exceptionally smooth running engine. The immediate and smooth reaction to the throttle, without the slightest surge, makes the VM 210 a first class power plant, not only for glider towing, but aerobatic models up to 25 kg AUW, without a noise problem, with well over 30 kp static thrust to catapult the model into the air. Once there was an advertisement by Curtis Pitts with the headline "going up in style", this describes very well the experience when flying my big Pitts with the 210B2-4T Mk.2.

Being a four stroke with a large capacity of 105cc per cylinder, causes a very realistic full-size aircraft sound. If required, even with a relatively small silencer the sound level is very low, rather like a small saloon car.

The Valach 210B2-4T Mk.2 is a four stroke OHV engine running on petrol/oil mixture. Valves and their seats are manufactured by Honda, ensuring a very high quality. The completely enclosed valve train reduces sound, as well as ensuring the rocker arms are well lubricated. Due to the steel cylinder liners this engine will have a long life.

Rear view of the new VM 210 B2-4T Mk.2.

The processor controlled ignition allows easy starting and a exceptionally smooth running in all throttle settings.

The recommended RPM range for the VM-210 on the ground is 4,400-5,000. Depending on the silencer, we have measured on the ground with the 36x14" Fiala propeller 4500-4800 RPM.

For the VM 210B2-4T Mk.2 installed in the Pitts Special S1-S, we use the Fiala 36x14" as this has proven to be ideal.

At 4800 RPM with the silencer #7293 we measured 35 kp static thrust. With the 2 in 1 silencer #7290 the VM 210 turns the 36x14" Fiala with 4500 RPM.

We had tried many oils, but recommend Valvoline SynPower 2T oil. Our BEL-RAY H1R although excellent for two strokes, is not ideal for four strokes, as it burns very well without deposit and not much gets past the piston, as is the case by the Valvoline SynPower 2T.

We recommend Aral Ultimate 102, as the smell is not so penetrating and it can be stored without deteriorating. It does not contain any ethanol.

The fuel consumption is approximately 50% compared to that of a two-stroke engine with the same displacement. A 1000 cc fuel tank lasts for about 15-20 minutes of flying time.

Our BEL-RAY H1R, although excellent for two strokes, is not ideal for four strokes, as it burns very well without deposit, therefore not much gets past the piston. With Valvoline Synpower 2T a lot more oil gets through to the crankcase. In Germany we recommend Aral Ultimate 102, as the smell is not so penetrating, it can be stored without deteriorating and it does not contain ethanol!
