Ergo 30/46 has developed a reputation as a sturdy little helicopter that can
take a beating and come back for more. The little Ergo and it's bigger brother
the Ergo 60 have been popular with fliers of all skill levels.
The Ergo's replacement is the Voyager line of helicopters. They come in 30 and 50 size variants and also a gas version available from Japan.
One downside of the frame design is that there is no longer a position to put
a needle mixing servo which the Ergo line had.
The front frame is rubber mounted which isolates vibration from the electronics. There isn't really a defined place to position the gyro sensor. In this case, the GY502's sensor was mounted on the underside of the radio tray above the fuel tank. Placement of sensors the size of CSM's 360 could pose a problem depending on the size of your radio gear. In summary, the radio tray provides limited space for electronic gear and as such the radio gear must be carefully positioned.
The boom mounting system is much improved over the Ergo line. Both boom clamps (at the frame end and off the boom stay) are very effective in holding the boom. Much more effective than the Ergo line.
Tail rotor gearbox design is similar in function to the Ergo line, however it is constructed of better quality plastic. The tail drive belt is of much better quality than the Ergo, being more like the Z230 than the previous Ergo. However, the tail rotor linkages are of the same design as the Ergo.
When we first viewed the Voyager kit, we were somewhat disappointed to find that the head is pretty much exactly the same as the Ergo, same washout, flybar rocker assembly etc. The only difference to cater for the 120 CCPM control assembly is the metal swashplate which disappointingly connects to a plastic top half.
The clutch is much improved over the Ergo line with being fully bearinged. Bearings have replaced the bushings that were used in the Ergo line in the start shaft which is supported by bearings top and bottom. This gives the clutch bell a very sturdy and rigid feel.
The clutch itself engages at very low RPM. However the OS50 with the bottom needle set quite lean will reliabily run at low RPM to disengage the clutch.
In summary, the Voyager is a more compact unit than the Ergo. The frame design
should prove to be considerably stronger in the event of a crash or fatigue.
The Voyager is a very fast machine with an OS 50 and CMT Carbon Fibre 600 blades. Vertical climb ability is outstanding. It flies smoothly without any untoward flight characteristics.
The machine does have a very responsive cyclic, however only marginally more than the Ergo. Rate of roll is very good.
Autorotations in comparison with the Ergo (OS50 and Fibreglass CMT 550 blades) was marginally better but not overly so. The tail drive on the Voyager is not driven during autorotations.
Now that the machine has had a few hours on it, hovering performance has improved and is now produces a very stable hover.
In summary, the Voyager feels much more capable in flight than the Ergo. It's much faster than the Ergo
The stock the machine is very capable and Darryll is very pleased with the machine. However, after watching it fly myself, I haven't been inspired to sell my Ergo and get a Voyager. If however, I write my machine off, I will most certainly get a Voyager instead of another Ergo.
The Voyager shows much promise in the 50 size market and has many improvements over the Ergo that it replaces.
