| Here is a summary of my impression of the Revolution so far. The Revolution is made by HeliProfessional out of Germany. They have previously released the Tornado helicopter and the Revolution has the same head and swash plate control system as it. It is incredibly light (9 1/4 lb) and strong. I am pretty sure that it has the strongest frame of all the RC helis out there, you could probably park a small car on the frame without bending it. The quality of the parts are excellent with very tight tolerances. some of the features that I like about it are:
- Very light weight
- Center of gravity very close to the head
- Flexibility of the control system configuration: 120 or 140 deg eCCPM or mCCPM with optional parts.
- Adjustability of the head: Can configure the head (stiffness, mixing ratios, leading or trailing edge blade grip control, etc.) for F3C to extreme 3D
- Parts included to convert it to electric power.
- The tail rotor control rod works by rotation instead of sliding along the boom => reduced inertia => less load on the TR servo => quicker response and longer servo life.
- Simple and quick to build
I got my Revolution from the first batch they released and it appears that they were pressed for time to get it out on time. I had a couple of issues with it:
1. There were some parts missing from the kit. I contacted Heli-Professional and they immediately sent me the missing parts but the shipping took awhile.
2. There was a 0.3mm clearance between the swash-plate ball and the main shaft which introduces a bit of slop in to the control system. I told Heli-Professional about it and they said that this was a problem with the swash-plates in the first batch of Revolutions. They did not have time to manufacture new swash-plates before first shipment but they will send me a replacement free of charge when the next batch arrives.
3. They also had a recall on the clutch bell but you can read about that on their home page. They sent me the replacement along with the parts I mentioned in number 1.
The next batch is due to come out in February 2006. Thomas Maier(Rototom here on RunRyder) is the sales / customer support person from HeliProfessional and he is very good at it. I have had quite a bit of correspondence with Thomas and he has been very helpful with prompt replies. I was a bit frustrated with the shipping from Germany to US which was very slow with DHL (4+ weeks) but they are now adding an option with another carrier for quicker delivery (for an additional price). You can also buy it from CyberHeli for $1300 but it is cheaper (about $1050) to buy it direct from Heli-Professional since they subtract the sales tax when they ship it outside the EU.
The only thing that I don't like about the design is that it is a bit cumbersom to take out the engine. You have to take off the exhaust system and the front tray (6 bolts) in order to get it out. Takes about 5 minutes to do but is a bit simpler on many other helis.
I am very happy with this heli and I love the engineering and innovative design on this heli.
