HIROBO X-spec - Freya - Sceadu - Shuttle > X-Spec -vs- Freya Evo

OK, I am completely new to the Hirobo line of helicopters but their reputation speaks for itself. Pardon my lack of knowledge but I am looking for a reasonable explanation on the differences between the X-Spec & the Evo 90. Are they both considered Freya machines? One is the Freya X-Spec and the other is the Freya Evo? From what I have gathered, the X-Spec is an upgraded Evo. The X-Spec has a bit of carbon in it where the Evo does not. Ron Lund does a pretty good comparison between the 2 kits from what I can tell.

My flying style does not include the hard 3D stuff so all the upgrades really won't benefit me. I am into the cruising around, lazy loops, rolls, and autos. Either machine would probably do me just fine. Any additional education would be greatly appreciated.

Thanks

The X-Spec is a "kit bash" that MRC did for thee US market. They took a lot of the Eagle 2 and 3EX parts and put them into the std Freya. This included carbon lower frames, engine mount, landing gear, metal head yoke, slide block/washout base, collective T-Lever, and auto hub.

The EVO came along about 3-4 years after the X-Spec as an all-plastic upgrade to the std Freya. It's got the plastic version of the new head, triple bearing clutch stack, and a larger fuel tank.

also, understand that when the original Freya came out, 80-90 size
engines were just coming on the scene and the weight of the Freya w/
a 60 gave 'relaxed' performance for most people. The XSpec was a way
to shave some weight and get back some performance.

You'd be best served w/ a stock Evo90.

The Freya Evolution is a development of the original Freya and Freya X-Spec. As noted earlier, the X-Spec was distributed by MRC here in the United States to satisfy a demand for a lighter more up-market 90 size machine. At the time, the Freya was essentially a 60 machine (gearing wise).

The Freya Evolution is really a different machine from either the X-Spec or original Freya. The difference being in the completely re-engineered head (the most critical part).

There were also evolutionary differences in the frames: New 22% carbon graphite composite, modified frame details (wire routing and easier harness access, support members moulded in), double bearing start shaft support, push-pull collective standard, new WC like fan hub, 18 tooth spur gear for tail drive (std ratio now being 8.64:1:4.77 (11tooth pinion, 18 tooth spur: Allows higher headspeed without throwing the tail blades), updated graphics, sturdier boom support ends, and other little details here and there.

The X-Spec is a more expensive machine than the Evo no doubt due to the use of carbon and its gorgeous metal head. It also added push-pull collective and the third bearing block, plus a metal washout base into the kit. This was done by MRC years before Hirobo built some of the details into the Evo kit.

Both are fabulous machines; however, I think the Evo would be better value for money unless you can find yourself a good used X-Spec.

The X-Spec kits currently being sold have both the stock X-Spec metal head parts, as well as the EVO head parts (plastic, though) so you can build it either way. The other upgrades and weight savings on the X-Spec are still of value, no matter which head you use . . .

According to my discussions with Jeff Green, if you really wanted the double bearing start shaft, you can use the EVO upper frames in the X-Spec kit as well - kind of an "EVO X-Spec" as it were . . .

Can you convert the plastic upper frames to carbon?

I *think* someone has done it - the EX frame set is essentially what is being "borrowed" here, if I am not mistaken. Pretty spendy though . . . hopefully someone who has done it will come along shortly. Not sure how much you would gain by doing it though . . .

The upper frames can be converted to carbon, but it is a rather costly upgrade. Also understand that there's more to the upgrade than the frames. Since the plastic frames also have in them the molded in bearing "blocks", all of those will be needed were you to convert the upper frames to carbon.

Plastic uppers and carbon lowers is a good mix of cost effectiveness with a bit of weight saving. For carbon uppers, you might be better off looking for a used EXII; they show up occassionally for barely twice what a conversion would cost you.
