Coxial Helicoptors
I want to know what is the best one to practice with in the house and outside with no wind. I know the Hirobo Quark is one of the best but what about the Blade mcx or walkera 4.3, I want something that I can ajust the blade tracing etc so that I can hover nice just like the adjustments on the Quark, with the Quark you can make all the same adjustments just like the larger helis.
Thanks

The 4.3 isn't a coaxial,...

One of the few coaxial helis with blade tracking adjustment capability is the Hirobo Lama XRB SR.

The Blade mCX is just bolt on and fly.

At one time way back when, there were not any electric helis to learn on. We jumped right in to a 30 size nitro or better yet a 50 size. Just take the plunge and get a big heli....

A sim and an instructor will go a long way...............

Coaxial helicopters are the ones with two sets of main rotors each turning the opposite direction the other is. These helicopters are almost always fixed pitch, and as such don't require tracking adjustments. Examples of these are the Blade CX/CX2/CX3/mCX Esky lama, and there are many others as well. This type of helicopter is very stable and easy to fly. Little to no wind is required to get them in the air.

There are fixed pitch helicopters that aren't coaxial, and instead use a tail rotor design. These aren't as easy to fly. In fact they aren't easy to fly at all. They tend to be smaller, and use the speed of the main rotor to climb and descend. Because they're fixed pitch, the rotors don't spin at a really high rpm, and are good for indoor use since when you hit a wall the whole helicopter won't explode, and destroy your house. Examples are the Hirobo Quark, and Walkera 4#3.

Tracking is usually associated with collective pitch helicopters. Generally these guys are quite hard to fly as well. On these ones the rotor blades have a flatter profile (symmetrical blades) than FP helis. The head articulates to change the pitch of the blades, and that's what makes the heli climb and descend. So while the head may be spinning at 3000rpm you can have 0 lift with the blades at 0 degrees, or even negative. That's what makes these ones fly upside down, and do the cool "3d" stuff. Tracking these ones is actually changing the pitch of one blade and not the other to get both blades to "track" on the same plane. Examples of these are the Align Trex series, Raptors, etc.

fwiw I don't recommend flying ANY collective pitch helicopter around your living room. Blades move FAST and will make holes in your drywall and explode upon impact with household items.

Can you give us a reason as to why your fixed on the idea of a coaxial heli? I, personaly dont like them myself for my own reasons. Another alternative that others have tried and liked allot is the Walkera#4-3b. Looks to me like a very good choice as an indoor heli and would recommend it over a coaxial any day.

If you want one of those, I have one with a bunch of spare parts, the alum case, etc. that I'm not really using anymore. I'd be happy to get rid of it to fund my flybarless endeavors..

I agree with JRjoe. Forget the coax helis and go for a 30 or 50 size nitro or electric. I was in your same situation a couple of years ago. But after reading tons of forums here, I bought a Realflight simulator, practiced on it for 3 months, and then went shopping. I started looking at the AXE CP and other 400 size helis. But everyone said they are 'twitchy' and hard to learn on. Plus you really can't fly them outside unless it is a perfectly calm day. My wife told me that I couldn't fly in the house. So I ended up with a 50 size nitro and found that it was much easier to fly than the small ones (I have since bought a small AXE CP). I set it up for mild flight and it was fairly easy to control in a hover. Definitely not 'twitchy'. Of course, there's a much bigger investment if you go that way. So you better be sure that you want to stay in the hobby if you go 50 size. If you do go with a small heli, look at the 400 size or larger. (By the way, I never fly my AXE CP anymore so if you're interested, I'll make you a nice deal on it.)Gunner

See you have a few other large machines, so assuming you just want an indoor machine and some opinions on that.

From my experience, I have Hirobo XRB (is by far the best quality coax), and best value was Esky lama 3. XRB is expensive, I'll keep that - lama 3 is a beater and cheap to repair. The difference between the two is like driving a new Honda versus an early 90's GM. Both do the job well, just one does it more precisely and quietly, and both will suit different lifestyles.

My brother in law has the lama 4, but not really leaps above the lama 3. His first one was a Walkera, and takes last place in the list (what a noise).

If the Quark is the same quality as the XRB, it should be good. Real good.

Like most things electromechanical, if you plan having it for a long time and there isn't a German one, buy Japanese. Want a year or two or three, Chinese.

Good luck.

Im with Jetfire. I own a 4#3b and I love it. It take a lot of abuse and I just got done flying in around in my den. You definitly need to practice at least in your garage or sowewhere larger to get the hang of it because it is pretty fast. Hell I landed it on the coffe table... I have also hit walls and it left no marks.

I love the blade mcx. They are a lot of fun and keep me occupied when it is too windy or raining.It's a complex, costly, glow powered anti-gravity machine!
