The radio/servo tray looks quite flimsy. What items justified the price increase from about $380 to $450. There are no more parts in this one than the HPM version. This heli definitely won’t below Align out the air. At our field 90% of the heli are Align. Good luck Hirobo.

Hmmm i don't remember reading anywhere that Hirobo is trying to blow Align out of the water!
And i imagine all the new moulds would cost alot to manufacture which would reflect in the cost of the kit! And with all heli's, give it time and the price will no doubt come down!
If your that worried you can purchase one for $399 from Hong Kong!
problem solved!

That does not bother me. I like Hirobo and will stick with them. That is my choice. I don't have to fly what everyone else flies, and I don't have to fly like everyone else does.

I saw the SDX in Toledo and I didn't think it looked like the tray was flimsy at all. There are always more parts in the Hirobo implementation of SWM and I expect that. The payoff is that the swashplate goes straight up and down and the machine flies true.

It's interesting when you go back and forth between a bunch of different machines like Aligns, Raptors, Hirobos, Synergy's and others and you fly them back to back just how different they handle certain things. Continuous slow rolls on the deck are effortless on some machines and require work to keep in one place on others. A lot of it has to do with setup and how tightly you want to mix out certain interactions. Hirobos like the TD3 tend to track truer upstairs and in 3D maneuvers with less effort than others. I expect that this SDX will do that too.

I'm going to give it a try and see for myself if this is true.

Hi all.

Andy: As mentioned, the gears are the black plastic ones same as the old Sceadu but the delrin upgrades fit right in.

Gary: Same as what Quickster said. In my personal opinion, I cannot compare the quality of Align, Thunder Tiger, CopterX, Compass Models, and similar helis to the likes of Hirobo, JR, Mikado, Synergy, MA, Kyosho, etc. Again, this is my opinion. In my country, there are now many Trexes flying in the fields because their initial cost is less than Hirobo and crashes are cheaper too. But most of the guys also have Hirobo helis. BTW, I had a Trex600 too but sold it recently

Quickster: The skids are like those on the Lepton, just bigger. They're a bit flexible like those on the original Sceadu but the height are same as the Freya/Low Profile Skids... but again, they're lighter. Hirobo included those rubber dampers between the frame and the skids, same as used on their Eagle3s.

Henrik, Tmoore: I agree with you 100%

Am currently uploading more photos and a short video (break-in). Will post my initial impressions soon.

Well, I had the same feeling when I flew the D3. You can get pitch of +/-15deg, pitch and cylcic are so responsive and the heli feels really light compared to my Sceadu. I think there's more to the head and control (SWM/135) design, and the weight savings Hirobo did on this new heli.

Poom: Yup flew it but hover and small circuits only (limited space). Have yet to go out to bigger fields and rip it up.

The grips and head design are not like the old Sceadu or Freya. For eg. grips have the flybar/pitch mixers attached at the grip like that of the Bergen and MA head design. The flybar cage is very different, see his pics. Basically the head is a 50 size of the Turbulence. I have not flown the SDX yet, but if it is anything like the Turbulence, you will love the change from the previous Evo purmutations. If you are always wanting a more zippy nick and roll, Hirobo has answered.

Gary, you are right from a price perspective. It is not the cheapest 50 solution out there. However, this field rep feels that the Hirobo quality, performance, customer service, and consistency is a hidden value added that shouldn't be overlooked. If you get a chance to put one through its paces, please post your impression.

Nicely put, Brian.

I must admit that I just don't exactly understand when people insist on trying to do cost comparison of Align to Hirobo and make that virtually the sole basis for juging the acceptability of a Hirobo product for the marketplace. In almost every aspect of a competitive marketplace, the public expects and is wlling to pay more for a better design and better quality and longevity, yet for some reason Hirobo isn't allowed to charge a bit more for a superior design with fine quality and customer support. This makes little sense to me. There is simply no comparison in parts quality or control system and head design innovation between the SDX and any of the current crop of Align 600's. I could write you a small novel about why Hirobo's SWM system arguably provides the single most interaction free eCCPM control loop on the market. And this ridiculous notion that some have that if it's plastic, it's somehow cheap in quality is simply ludicrist. I'll take a precision molded, low cost to replace plastic piece over a mismachined, out of tolerance aluminum bling part any day of the week. I just wish the more cynical members of the public would have the courtesy to give this model a fair shake instead of immediately challenging its ability to compete against the pseudostandard set by Align. If the product is good, it'll take care of itself. The SDX can surely stand its ground.

i couldn't agree more ben

i've worn my 600 out in 18 months and has just been overhauled ready to sell the airframe
my sceadu (non evo) is still going strong without much wear
the main and tail gears are getting well worn but thats it
and it still fly's great

i'm in the market for an sdx when we can get them in the uk

and the 600 isn't going to fly again
align may have cheap crash items but when you look at the cost of the other parts it isn't so cheap and they wear out a lot quicker that the better quality brands

Is that tail linkage a one piece item? It almost looks like a wire in a tube!

Thanks guys.

Quickster: The tail linkage is indeed a wire in a tube. The same diameter wire used in the old sceadu but longer to reach the servo frame where the tail servo is now mounted. On the HPM version though, it's still mounted on the boom.

Some other things to note (compared to Sceadu):
- there's now a radial bearing included on the plastic auto-hub which is not on the old sceadu. The bearing is on the upper part of the hub.
- the area on the plastic main frame where the SWM control levers/linkages going to the swash are mounted is different on the old sceadu frame. Material had been removed to accomodate the plastic control lever mounts. Hirobo did modified the old Sceadu frame molds as there is still 2001 imprinted.
- fuel tank is the same as Sceadu
- Hirobo included many inserts/additional info on the manual, very helpful.
- the canopy is really nice, I want another for my old Sceadu
