I am not sure where I am now, but the machine can handle alot of cyclic without bogging down.

This thing can go so much more but with that you have a stalling factor. Whats been working for you?


That depends a lot on two factors. First the kind of blades and paddles you're using are very important as to how much cyclic you can throw at them. Second the delta spacer washer setup also determines how much extra cyclic bite the blades will have due to delta effect. The more washers (0, 1 or 2) the less bite and therefore more cyclic needed. The only way to be able to tell is by flying your particular setup and increasing the cyclics travel percentage until you get the response you like like Evan did. For instance Ray's cyclics are excessively fast for my taste and makes it difficult for me to get used to his machine but that's the way he likes his machine to respond and it works for him better than if he had my setup so each person will have a setup that works for him and another person might hate that setup. The nice thing is that you have a very wide range there to adjust it to your liking.

Do you know if they are going to put together a blue print of the machine. the instructions are a little vague in certain areas and would be nice to have a print to reference to. I really like that instruction referencing to red, blue ect. dots in the pictures and every thing is in Black and white. LOL.. got a kick out of that.


I think the manual you got was a preliminary manual. There is an updated manual that has the locations indicated with both arrows for B/W and colors for the online viewer. The color reference is for the online version that you can se in full color. Click here to see the latest version of the manual. I was reading a printed version of the manual and also got a kick out of that. As time passes the manual will be more a more polished from the feedback we get like yours.

There seems to be a descrepency on the ccpm shaft. Mine seemed to be threaded on the wrong end in reference to the instructions and pictures. I still got it to work but Just an FYI.


Page 18 of the above referenced manual has the correct instructions for your version of the ccpm control shaft. There is no difference between them other than the collar goes on the other side and only one screw. The system is compatible with both versions of the shaft.

Just some of my observations in building the Avant:

1. the carbon tail rotor control rods included with the kit are two piece item that I am sure is for packaging reason. Go to your LHS and obtain a one piece 4mm carbon rod to replace this. Carbon Extreme also sells the optional one piece rod if you prefer.

2. the supplied 2.5mm bolts for head modification (8mm and 10mm long) is not of the same high quality as the rest of the bolt. It is of a softer variety button bolt and have a 1.5mm hex fitting. You will easily strip this during installation, let alone upon removal. Original bolt for this area from Hirobo is 2.6mm cap screw with 2mm socket head. Both 8mm and 10mm versions are available as Hirobo parts (sorry Augusto :-)) Save yourself some grief later when you have to remove this part

The kit quality is in general excellent, could use some finishing on the cnc'ed parts (this will increase cost?). My kit also miss one 17mm spacer for the tank side plate.

Avant kit

The kit quality is very high.

The 8 & 10 MM bolts for the ratio block is a weak point. When I assembled the seasaw assembly, I installed it backwards and Augusto informed me. Being Red Locktited, the bolts stripped. Augusto quickly sent me out new bolts.

The ratio block would need to be redesigned to accept a larger bolt head. But... once these are installed, no reason to change them unless due to a crash.

I will also probably change out the 2 piece cf pushrod to a 1 piece one.

If these are the only complaints about this kit, then it is a winner out of the box.

I did the one piece pushrod. I was unhappy about the hairline fracture that I got with the two piece rod when I tried to install the threaded ends. I also feel better about having it one piece instead of two.

On the two pc rod i opened up the ends a little for the stainless rods to fit. This seemed to work rather well. Just my two cents.

Great input on the ratio blocks. I had concerns about the soft bolts also.

The reason behind the 2 piece tail pushrod is for traveling reasons guys. Augusto and I both have been using this for a long time now and it works fine and when you need to ship or travel with your heli to a funfly it will unscrew to 2 small pieces and fit in anything.

Guys we all become Avant crazy here, but I believe we should not do it this way...
Let's just get our kits and give it a test at first...
If we will find any bugs than it will be better to PM Augusto rather than start a discussion about this.
Just think about guys who may not understand that it's just a bug, joke or something like this and who may start to think that Avant is really got some serious problems. We all know it’s not...but still some folks may misunderstand something...Check this thread
Augusto helped us a lot and he is still helping, so let's help him.
Just get your kit, assemble it, give it a try and if everything is cool than start a happy topic about Avant. But if you will find some bugs or something just PM Augusto, cause I believe this information will help him to solve this problem and make the kit even better!

Thats to be expected with any new products, but the fact that this one is SO DAMNED COOL, doesnt help the supply situation. I know Augusto and everyone at CX must be working their butts off.

Just hope they get a chance to catch up sometime, then they can sit back and enjoy the publicity.

It wasn't a "bug or problem" that I had with the 2 piece t/r rod. I f'd up when I tried to insert the threaded ends and a hairline fracture resulted. This being my baby, I didn't want to take any chances. If I had the right size drill bit I would've opened it up a bit to make it easier to insert the threaded rod. I p'med Augusto about my f' up and asked if they had a one piece rod available. He told me to contact customer service at Carbon Extreme to order it. I can say dealing with the people at C/X has been a pleasure. If only the weather would get better now. It has cleared up but the ground is still mushy and if I try to drive onto the flying field I'll get stuck.

As far as finishes such as the blue anodized or black anodized I agree they make parts pretty but we decided not to go for that. The problem with anodizing a part is that the anodization makes the part non-conductive or in other words electrically insulating. As some of you are aware one of the reasons for radio lockouts is lack of grounding due to non-conductive parts. That's why some kits like the Vigor require to install grounding straps to prevent radio lockouts.
The same way you can get steel alloys that are corrosion resistant such as stainless steel there are some specialized aluminum alloys that are corrosion resistant. Those alloys are a bit more expensive but they allow you to make parts that require no anodization but that at the same time are electrically conductive. Use of this alloy allowed us to have every part stay electrically conductive eliminating the need for any additional grounding. We chose protection against lockouts over pretty finishes.


Regarding the ratio block bolts,

The spacing between the two bolts was pre-determined by the spacing between the existing threaded holes of the seesaw. This pre-determined spacing prevented us from using regular socket head cap screws because the head of the lower bolt would hit the body of the higher bolt.
Being that the case we are forced to select a head the is smaller in outside diameter hence the button head. The bolt is not softer than the other bolts in the kit what happens is that the button head uses a 1.5mm wrench hole so it makes it easier to strip especially if you're trying to extract a red loctited one. What I said was that if we selected a harder bolt so it would be harder to strip then it would be brittle and it would make it prone to break due to fatigue so in order to prevent that we have to stay with the correct alloy same as in the other bolts in the kit.

Using a smaller diameter socket cap head as suggested above has the problem that those heads are much taller than the button heads we use so it would force us to machine the hole where the head sits much deeper into the block. Machining deeper holes so that the taller head can fit would weaken the part by reducing the total amount of metal that supports the tab where the mixing arm is installed so as you can imagine weakening the part is out of the question.

This is why we included the #262 red loctite in the kit. The #262 red loctite is the only red loctite that can be easily removed by heating it with a heat gun and as specified in the instructions it's the only one to be used in that location.

As you can see is not that the the bolts are weaker they are the same alloy as the rest of the bolts. They simply have a small wrench hole that's easier to strip than if the wrench hole was the one from a regular head. They just require careful removal by the application of heat so they don't strip.

I will give instructions so that they include more of those bolts in the freebie spare parts bag that come with the kit.


Regarding the two part carbon pushrod

We make it into two parts because it's easy for packing when traveling. The boom fits into a large suitcase but the single piece carbon rod with the threaded ends installed won't fit into any large suitcase. When I went to IRCHA I had to take it in a cardboard tube that's a pain to carry through security and that I ended up forgetting at the hotel. When I got home I swore I would not let people go trough the same headache as mine. We have been flying the two part one for a long time without any problems. A single piece rod is available if wanted. The part number is CX00-100-707.

Regarding the holes in the carbon pushrod

Carcrasher is correct and from his feedback we started to ship the pushrods with the ends pre-drilled as nvert72 did to make it easier to install.

Lipo packs

has any one had any experience on running lipo pack for a rcver pack.

I just got a 2cell 2100 Lipo for a rcver, with a volt reg. I would thing that this should be a great setup, exp for wght.
