Okay, what are you fishing for? I can't even smell the bait!

Avant. . . . Sure, I want one, but I'm not going to buy a $500 to $800 kit from Hirobo, then a $600 "conversion" kit from someone else when there are very viable and similar competitors models available for $850 or so.

Even if the Avant ends up being a little tiny bit "better" then the others, it doesn't seem worth it to me.

I DO like the fact that it's a Hirobo with CCPM. I want my next machine to be CCPM just because I like the technology.

I think he was simply going to do a search on avant and click on the post thread instead.

Avant

Glenn,

The Avant does not even fly or feel like a Hirobo. I have an Avant, 91 Freya, and EVO 50. I also had an X Spec.

Lasy Sunday I had all 3 out. My 91 Freya is nothing like an Avant in any way, shape, or form. (although my Avant does have a Freya canopy on it at the moment).

My Freya is a great machine. The Avant is just smoother, flies much lighter, and is incredibly responsive to the collective and cyclic input. Auto's (V Blades) are nothing less than amazing (light weight).

The cost is $465 for the old Freya kit and $585 for the Avant conversion. No need to buy an X Spec first.

I was going to delete my post based on what Augusto said but there are too many replies now!

I saw one fly and I looked it over carefully and I'm impressed. I was just turned off by what I thought was a $1450 price tag. I must have received some bad info.

There is one chap trying to sell one for $1250 though!

Well that is good to know that one can be had for $1050. I will have to take an even closer look now.

Yeah that's a common misconception thinking that the Avant is more expensive than say a fury or so.

I look at it as a $1K heli that flies like a $3K 3D monster... hehehe

Is that your new sales pitch.

Hi All,

I built both of my Avants from used X-specs. If you watch the classifieds, you can usually pick up an X-spec for a reasonable price.

Like others have said, they are awesome machines.

So how does it compare to Freya Evo and Xspec.
I have Xspec and love that thing.Had R90 and Fury before and for some reason I have best "understanding" with the Xspec.
Was thinking of Avant for some time,but don't know if it's worth the money.
I'm no Curtis and probably can't do 50% manuevers my Xspec's capable of,but seems to me I got better in "light 3D" after I've switched to Hirobo.

So let me hear it Avant owners.

I was going to post a question to see if the Avant could take a YS 61 instead of the 91. I got the information in a old thread. My conversion kit shold be here soon.

Thanks Jason

I too am only into mild 3D but the Avant is so nimble that you find yourself doing the maneuvers much lower than you normally would have. The heli is very quick on cyclics yet it retains a very stable hover. I wish I could comment on how it compares to the Xspec but I never flew mine before I converted it.

I think a YS61 would do fine in the Avant. Just make sure you use 60 size gearing.

I think anyone opening the CarbonXtreme Avant kit will be incredibly surprised. It comes fully loaded with ball bearings, the carbon is awesome, the mechanics rigid. Really, it is very impressive even before you put it together.

I've now got one but have been working the past few weeks and am just now installing the servos.

Nobody would be disappointed with the Avant. It's beautiful, and I'll tell you more when I fly mine.

I have one quick question about the Avant. Upon installing the main shaft, which end do I use?

Thanks Jason

Here's a picture of the shaft in place.
The larger holes go on top and the smaller one on the bottom.

I will be using the 9.5 gear ratio. What about the mainshaft bearing blocks, do I still leave the notch on the bearing facing backwards or turn the blocks around? Same question on the clutch bearing block.

In the case of the plastic freya there is no way to change the location of the mainshaft or the pinion so there is only one distance between the mainshaft and the pinion that is used for all the ratios available in the plastic freya which include the 9.5, 8.45 and 7.92

The distance between the centers of the starter shaft and the mainshaft in the Avant when built for any of those ratios is the same as in the plastic freya so any ratio that works on the plastic freya works on the Avant. The only difference is when you need to go to 8.08. That ratio can't be used in the plastic freya because it needs a different mesh. In the case of the Avant it needs the front bearing block flipped so that the spacing matches the 8.08 mesh.

Here's mine





After all that time - test flew it yesterday - feels awesome.

Ordered May 17, finished Sep 17. Wished I had more of the summer season left to play with it.

Shagga:
I noticed you are using the Hatori pipe. Is it the 970?
Also, that looks like the stock Hatori header too. They are far too short for use in helicopters-unless you are running at peak power all the time and don't fall off the pipe.

I found those short headers to be useless on the helicopter. I found that you need a pipe length of around 440-460mm (measured from the flange of the header to the first baffle inside the pipe. That way, in normal operation you are on the front side of peak power (making less than peak). Then, as your rpm drops you roll into peak power which gives you the torque when you need it. The system then becomes self regulating and you don't need a governor.

I found that with the short Hatori headers I had terrible overspeeding and when you fell off the pipe, the helicopter had zero power and you really had to unload the system in order for it to recover.

That's why they don't use the Hatori 632 header because it's too short. They usually use the zimmerman and cut about 15mm off of it which makes it still longer than the 632 header but not as long as stock. You could also try a longer connecting piece of tubbing to increase the length lowering the peak RPM pipe resonance point.
