Robinson helicopter, Enstrom helicopter, which are you going to pick? Hello, I'm Kenny Keller, the creator of Helicopter Online Ground School and I've had the opportunity to fly both of these great aircraft over the years as a student. I've flown them as an instructor. I've been paid to fly both. I'm going to start with the 2 different rotor systems that they have. The Enstrom is a fully articulated rotor system and is called a high inertia rotor system, which I can tell you is very, very good. With the Robinson R44, it's a semi rigid system and depends on who you talk to, whether they call it a low inertia or a high inertia. Definitely more inertia than the R22, which is a good thing.
One of the biggest benefits of the Enstrom and the high inertia system, the auto rotation is absolutely incredible. If you enter it nice, it's not a lot of work. It's very, very stable. The semi-rigid system on the R44, it's nice, it's smooth, it's up, it has some inertia in their. R rotations aren't too bad. They're pretty decent as well. Between the 2 which is going to be better? That's something that people are probably going to argue back and forth. Rotor system on the Enstrom I can tell you is pretty darn tough. I survived a helicopter ground resonance incident about 10 years ago in the Enstrom 480, basically the same rotor system. Even though the entire aircraft was destroyed, the rotor system remained intact.
The only thing that was left of the aircraft was the rotor system and the rotor blades pretty much unharmed. With the R44 and the semi-rigid, there is something they call low G mast bumping that can be a catastrophic event and the fully articulated system does not suffer from that low G mast bumping. One thing there that probably would make me lean a little more toward the fully articulated on the Enstrom. Now just in case you're thinking oh he's already going to favor the Enstrom, let's go to the R44 and talk about some of the good things about the R44 that you don't have with the Enstrom. The R44 is a 4-place helicopter. You can see 2 in the front and 2 in the back. The Enstrom they call a 3-seater. To be quite honest, 3 reasonable side adults like 3 normal size guys, they get in there and they're pretty squished in there. To call the 3-place, yes it is a place but it's going to work best with say 2 adults and a child in the middle, okay then you can call it a 3-seater. For the next plug for the Robinson, I personally think that the R44 as far as doing commercial operations is going to be the Enstrom hands down due to the fact that, let's use the example of helicopter rides. They have helicopter rides as a type of commercial thing that you want to do. You're going to be able to see 3 people, 3 pretty much normal sized people. You have a bigger engine, so you have more available power and for that operation most definitely.
I've done helicopter rides with the Enstrom, but again it's a 3-place, 2 and a half place. You have one person that might be a little on the heavier side. You're only going to be able to take up one person on that helicopter ride. For a couple of helicopters that are general vicinity of that price range of what somebody will be looking at for a personal aircraft or possibly doing some commercial stuff as far as helicopter rides, you're not going to be able to beat the R44. Hands down, and I know quite a few people out there doing like say crop dusting with R44. I'm sure there's probably some people doing it with the Enstrom, but I don't hear about it a lot. It's its more common as far as I know in the R44. Next, we'll cover tail rotors for just a second. The Robinson is known for having a really good design on the tail rotor and a very effective tail rotor. I can also tell you that the tell tail rotor on the Enstrom also has pretty good reviews and they say that it's a really good system and a really good tail rotor as well. As far as flying the 2, I can't tell you that I noticed any big huge difference and I really would have no pic as far as which one would be the better. Next, I'd like to talk about the 2 as far as from a training environment with the fuel. With the Enstrom, I like that a lot because it has two 20-gallon tanks. There's a factory fuel stick that's right inside the door.
