Gotta do some bitching about Hirobo...
I just finished about 95% of the conversion to make my Evo SWM using the Hirobo kit. Here's the complaints:

WHY IS THERE NO MANUAL?!?! The stupid sheet included points you to a Hirobo Japan website that doesn't have the instructions. I shouldn't have to come on here and search for a manual to get it set up. What is the person who doesn't live on RR supposed to do?

How come Hirobo can't make an antirotation guide that fits? Why the use of difficult to insert spacers? What, couldn't put the extra 5mm in the plastic mold?

Other than that, it's a nicely engineered kit. I like the large pile of parts I no longer need because I've done this conversion, and it should bring the CG microscopically higher with the way the servos are now setup (I'm reaching, but hey, I can brag to the Raptor guys at the field). I can't say that I feel there were $75 in parts in the bag, but then again, what is cheap in this hobby? It seems like a stock Evo and stock crash parts are cheap, but upgrades like this are astronomical. Oh well. I've had the heli for a year, I've loved every flight with it, and with my $75 investment, it's like I have a whole new heli, and it gave me a good opportunity to do a real thorough cleaning and check everything over, since all the bearings were exposed, and I did the bearings in my Hyper at the same time.

i agree with you on both points, no manual pissed me off so i had to use one of the pdf's on here, ended up not even finding the plastic version had to use the sceadu swm 3d/metal manual. also agree with you on the anti-rotation guide man that was a bish to get in.

either way you got it done as i did after a little bit of a struggle and i DEFINITELY believe it was worth it. INCREDIBLE difference in flight, i love the hell out of it. ordered the full options evo in swm, and ordering a new evo in swm

Yes, mine had two cross members and the anti rotation guide. I figured the only way to get the cross member in was to loosen the frames, then when i came to the anti rotation guide after more struggling i came to the same conclusion. Next time it will be easier

I have scanned the necessary pages of the SWM evo manual, if anyone wants it let me know - email me directly. this would be very useful in converting to SWM. john@eellspdx.com I'll post it to a website if anyone is interested.

I'll have a pdf here, look back later - it'll be from cover to page 49 which covers the build, but not the parts list - I'll get those pages added later

Just to save you some effort, it's already up, I got it from here yesterday:

The only drawback is that they require registration.

I hate to sound like an ignoramus but what is SWM? Is that some sort of new fancy swashplate mixing like CCPM? What is the advantage of converting your bird to this?

Sorry, but just trying to keep current after being mostly out for the last three years.

SWM is what hirobo calls Swash Mixing, rather than HPM Hirobo Mixing. Swash Mixing is simply CCPM. Don't feel bad, It's all new to me. And I think for the most part CCPM is a pretty recent development in swash control - taking advantage of cheaper heli radios with more powerful mixing features. I gotta say my sceadu flys awesome !

Like he said, SWM is Hirobo's name for CCPM. Now that I've converted mine I can say I've flown the exact same heli with CCPM and without. It really doesn't fly all that different. The collective has a little more pop to it, and I've got a tiny bit of interaction that wasn't there before (I'll mix it out, I just haven't done it yet). The big advantage I see to SWM is that I lost a lot of parts, and tidied up the helicopter. I like that I can now easily access the set screws for the starter coupling, where before it was a real pain. I also like the idea that all 3 servos are sharing the load, instead of the collective getting hammered while the others had it easy. The disadvantages to the HPM are that the setup is a little more difficult, although if you've ever set up a CCPM heli before, it's really not, and I have had CCPM helis before. The other disadvantage I see is that before you could put relatively cheap servos on cyclic, and put a big dollar servo on collective and it'd be fine, since there's not much load on the cyclics, now you need good precise servos on all 3. In all, I like the SWM layout better, and I'm going to stick with it. If I buy another Evo in the future, I'll go right for the SWM kit instead of bothering with the HPM.Nick Crego

nick, sounds like you have much more experience than me - how do you figure out what your interactions are or might be ? and diagnose what to mix out ? Thanks for your ideas.

antirotation guide installation
make sure you have the spacers aligned correctly. There is a slight raised lip that fits in the frame side. If you have it pointed towards the anti rotation guide it will make it very difficult to install the other one.

MHW did an article on both versions and concluded almost no difference in flight characteristics.

I have a Tiger 50 with 120 eCCPM. After many crashes and losing a servo I kinda am leaning towards mCCPM. I just picked up a couple EVO50's that are HPM. My first experience with standard mechanical mixing. I like the safety of the linkage which I truly believe adds a bit of cushion in the event of a crash. Having servos right there at the swash with one link is a recipe for servo failure.

Don't get me wrong I'm not preaching mechanical as the best. There are problems with both and advantages.

Todays digital servos are expensive.

the anti rotation guide has spacers because they decided to save you some bucks by not re-engineering the part and using the one the shuttle zxx has used. By making spacers, they avoided making a mold, a prototype, a new part number and a lot of frustration for a part that is relatively low production run. It is a heck of a lot easier to g-code an aluminum spacer that can be mass produced on a CNC lathe.

As far as the manual, well, every Hirobo manual I have had kinda stinks anyway. I wish they would hire someone who "please can to translate manuals for happily together us, to reading make for better and enjoyable construction goes."

IMHO, the SWM does fly different, specially if you are into hard 3D.

In spite of all those shortcomings I will still stick to hirobo heli. The overall quality is great anyway.
