Hi guys, just got a huge box from UPS packed with heli stuff, the Octane Dominator 20cc from QWW is here. This is a heli sent to me for free from QWW as part of their challenge to let people see what their stuff is actually like. They sent it on their dime, and didn't charge me anything for it, when I'm done getting it together and seeing how it flies, I can either send it back, or buy it. I've got to commend them on that, it takes huge balls to send your stuff out for review like this, especially to someone like me who doesn't pull punches and has had problems with QWW in the past. I hope it turns out as well as they hope, I'll give it a fair shot here.

I'm going to update this thread with pics and text as I go through the build, and after I'm done, I will edit everything together into a single post that will help people searching for info on the machine without having to dig through a long thread.

First impressions are good. This is not the nicest heli I've seen, but it certainly isn't the trash that many of the bashers would lead you to believe (and much better than the old EP10 I had years ago). I thought I was getting a full kit, but the mainframes are already assembled with the engine installed. However, the rest of the heli is in kit form, and looking at the preassembled parts, nothing is tightened down or locktited. so I will be going through the preassembled frames as well.

The carbon frames look to be well done, and the quality of the metal parts also looks good at first glance. The machining on the metal isn't the best, there are tool marks on them (you can see them in some of the pictures), and the anodizing isn't perfect, but if they function well, then I don't have any real issue with the machining and anodizing. It does look like the parts are well thought out, with lightening holes where appropriate.

I took some pics of the highlights and lowlights, here's what I see at first glance that I like:

Nice swash, tight, no slop, with nice smooth action. There are some mounting options on the rear balls, perhaps another mixing system? I can tell you that the swash out of the box is better than the one that came with my $600 RJX Xtreme, or any T-Rex I've owned.

I love that the fasteners come in a little plastic toolbox. Nice touch. Unfortunately, it'll make assembly more time consuming than the standard bagged screw sets that come with most helis, where all the sizes are grouped together and with each step. It would have been better if QWW had grouped the fasteners according to size instead of how it is, which appears to be according to type (socket heads together, button heads together etc).

It has a very interesting flybar cage design, as you can see in the pics. I've never encountered it before, instead of using set screws, it clamps onto the flybar. It's probably been done before, I just don't remember seeing it, and I like it. Simple, and it won't put burrs in the flybar that make it hard to adjust or remove.

The CCPM levers all come off of a single shaft, which I've read makes the geometry better. It's very similar to the 600N.

There's tons of room for components. There's no way you'd ever see a "Where do I mount" type post on one of these.

Split collars on the mainshaft - Why do heli manufacturers do it any different? These are by far the best way of making a collar.

Nice exhaust! It's a KS, I've used KS on my giant scale gas planes, very nice exhausts.

Not so good:

Machining isn't the best. There are tool marks on every part, I remember a thread a while back about "sweatshop" quality on the finish of a YS50. Those guys would have a field day on these parts. Like I said above, they appear to be good quality, just not finished very well.

Open bearings, there's no seals/shields on the seesaw bearings in the head. I don't anticipate these lasting long, junk is going to get into them. Don't know about the bearings in the rest of the heli, just what I see from a quick inspection.

Fan shroud doesn't center up, this may be just that it needs to be adjusted, but the preassembled main frame/engine/shroud has the plug way off center. I'll see what can be done when I go through it, may just need to be adjusted.

Main gear/pinion/tail drive assembly isn't smooth at all, there's a ton of drag and it feels very rough. Maybe the mesh just isn't set, as it sits the bottom gear that drives the tail is a fraction of a mm from fouling on the tapered part of the pinion, so it may be able to be adjusted.

Solid tank mounting - as you can see in the pic below, the tank sits right on the edge of the carbon frames with no padding or isolation. I'll go through the manual and see if there's anything suggested, if not I'll take it apart and cut some fuel tubing to buffer between the frames and the tank, if for no other reason than vibration and the sharp edges of the carbon will eventually cut through that tank.

Other impressions:

Nice looking canopy, but it's HUGE! I took a picture next to a Fury canopy of comparison.

The fins are TSK fins. If that doesn't make you laugh, you need a history lesson.

That's about it for the preliminary report. In all, it looks like a nice machine. I'll build it according to the instructions, I'm not going to modify things, I won't be filing, grinding, or adapting any parts. If I come across something I can't find the immediate answer to in the instructions, I'll see what QWW has to say before proceeding.

Doesnt look too shabby, I look forward to your review. I hate that anything comes pre-assembled though: especially so much of the heli. You can never trust an ARF part without just doing it yourself

I don't think that they usually come with the frames assembled. I guess I'm just special.

If thats the case then this whole review kit is probably "special" as well. If true, then its too bad they didnt just grab a full kit off the wall and send it to you like they said they would. Anyway, I still look forward to your comments, but would love to hear from someone who has purchased this kit before to see if its usually in kit form or not

I guess the good news of this is that you should have that thing flying pretty shortly.

We'll see, I just took another look at it, and the assembled parts aren't adjusted at all, the clutch is hanging half out of the bell, the gears aren't lined up, and a few other things. We'll see, I may get to work on it tonight for a little bit, I have a R50 and a 450SEV2 that I need to finish building for a local client before I can really work on the 20cc.

I am sure Eury is fine with me posting in his thread. If he asks me not to, I wont. Like I said, it looks pretty good - I just wish it was in a full kit form from the start, helps make a more thorough review process does it not? Anyway, regardless of what they sent Eury will tell it as he sees it, and thats refreshing.

Looking forward to your progress with this heli Eury.

You are correct on this point RC. It does seem that most problems we heard about were because of incorrect assembly. Though I would rather hear about the kit, not that it is possible to put a bearing block in upside down ya know.
I will make sure when i do the review of the Bat 50 that it is a total kit, not with pre assembeled parts. I will be picking it up this sat. So should be starting the review on Sunday.

Whoa!!! A canopy that makes the Fury canopy look small

I am very interested in this thread. From reading prior posts, I think Eury is the perfect person to handle this review and I am looking forward to the results.

Thanks guys, I may work on it all day tomorrow (at least while my son is sleeping) and get it in the air this weekend. We'll see, but I may be able to.

I've been in communication with Irwin, and he assures me that the unshielded bearings in the seesaw pivot is an isolated incident, and the fan shroud is something that new molds are being made to correct for. I've dealt with Irwin a bunch in the past, and the communication I've had with him recently are nothing like the Irwn of old. I'm very pleased with our recen talks.

Isolated incident
I also have unshielded bearings in the new head block I just got from HHI.

I don't like it either, but the heli has been down for a few weeks due to the rotor head so what am I gunna do? I'm just going to fly the heli and replace them in the future.

I've gotten several PMs, and everyone has said that the bearings in the head are unshielded. So, take what I was told by Irwin as you want, I was told that he ordered shielded, and they are supposed to be shielded.

I didn't get a chance to even touch the heli today, too busy, but I will spend some time on it this weekend.

I just checked mine, i have shielded bearings in the head block for the flybar pivot. I dont have that great looking flybar bridge carrier though.

we can never have too many, can we ?
