I'm interested in getting back to F3C type of flying after a long term absence. Can someone explain to me the current versions of F3C type models available from Hirobo and where you purchase these from.

None of the on-line dealers I've looked at seem to carry the complete line. Perhaps some are a special order. Based on this, I'm curious about parts support after the fact also.

Thanks in advance for any help.

Dr.Ben will surly tell you everything you need to know.
In the mean time take a look at.

If you are flying F3C the Freya and the Eagles are the way to go.

As you may know Hirobo amoung the best, especially for F3C.

My name is Greg and if you make up your mind and find the right helicopter that you would like after talking to Ben. I will gladley special order it for you if it is not in stock.

Among the models in the Hirobo line, we start with the Evo90. This inexpensive engineering plastic variant (with ali parts where they matter, like the head block) uses the FFZ-III head. It works VERY well. The latest versions brought into the US by MRC have the needed EX hi torque auto hob. The mechanics are incredibly reliable.

The Freya OP adds metal parts to the Evo 90, including the all metal SSZ-III head.

The Freya OPII comes complete with the new SSZ-IV head and eCCPM. This model and head were intended for 3D, but with a simple gear ratio change and manipulation of the head's mixers, it makes a killer FAI model with no other added parts but a clutch bell and maingear.
Even better, the Evo/SSZV OP comes with the correct gearing and the eCCPM parts.

The Freya Evo SuperIII is pretty much configured like the Evo/SSZ-V except it uses the other new FAI head, the SSR-VIII(edited).

Now, the aforementioned models all use the fine Evo90 engineering plastic core chassis. For about $1000 more, the Freya EXIII adds an all carbon mainframe. This model uses the SSZ-VIII rotorhead.

The ultra premium Eagle 3 AOCC is an SWM all carbon work of art with the SSZ-V rotor head.

So, what the heck should you buy? If your budget is on the lower end of the scale, then get the Evo90. If you can afford a bit more, the best choice is the Evo/SSZ-V. The EXIII is superb, but my personal choice of rotorheads is either the SSZ-IV or, better, the SSZ-V. Of course, the flagship Eagle 3 is the best you can get, and it comes with the SSZ-V head.

If you ask specific questions after reading this narrative, I'll be able to tune a recommendation exactly to your needs and pocketbook. As noted, Greg is extremely responsive to customer requests for anything in the Hirobo product line.

Ben
with all its available mixing ratios on the head and using the sdx50 dampers how would the turbulence do on a f3c set up?
yes i do know the turbulence was aimed at the 3d market but it is a realy fine and stable flying heli

its just a thought from your above excellent info (as normal)

Thank you to everyone for the response. I take it that other than the basic Freya Evo 90, these models are custom ordered directly through MRC. Is this the same with the parts for these other models?

I wanted to find more information (pricing, details, etc.) about the different variants that Dr. Ben spoke about. So, I went on the MRC web page:
www.modelrec.com/rc-products/helico...level-to-3d.asp
and couldn't find all the models listed in Dr. Ben's response. Am I in the correct spot? There doesn't seem to be much information on these models there.

Finally, is SWM Hirobo's name for eCCPM?

Thanks in advance for your assistance and patience.

First, the D3 question:

The entire D3 control system is perfect for FAI. It's the gearing that is not ideal for the headspeeds we typically like upstairs put the engine rpm above safe range with the stock gear ratio. Right now, you can't change that gear ratio because the D3 uses a 12 T pinion with a unique maingear with fixed component spacing.

Now on to the other question. Of late there has been a bit of misinformation spread about Hirobo and the parts support for these and other models in their line. MRC actively keeps parts for the Evo90, and they have a ton of parts for many of the Freya EX's and Eagles as well. If they don't have a part, they'll gladly order it. PERIOD. Hirobo supports ALL of these models. The relatively narrow market for premium FAI models limits their ability to keep every part for all the models all the time, but they are happy to get what you need. You'll rarely see all the models that I listed at most retailers because those kits are either new or are otherwise narrow in market focus making it unwise for a dealer to have one just sitting on the shelf. Thus when you find the model you want, have your dealer get it for. At most, it'll take about a month for it to come in stock. Whatever question you may have about any one of these models can be answered by me in rather exaustive detail, so by all means ask away...If you'd like to see the plans for all of these models, go the the JAPANESE Hirobo homepage and select "parts" on the left side of the screen. Those buttons are in English, BTW.

No, it's not. SWM is a patent by Sanwa (Terry Moore still hasn't told me exactly what it means from the Sanwa people he knows), it's their version of CCPM. Hirobo just uses it under license.

There is nothing to stop you implementing CCPM anyway you like. Some are just downright awkward. Others quite symmetrical etc. . .

SWM is nice in 120 and 135, although probably not in 140. With 120 you have the front ball having less angular throw than the back balls in heli lengthwise direction. SWM tries to compensate for this by having the axis of rotation at the 75% point of swash size. That way, all 3 bell cranks are the same size.

in 135 it's even better since now all 3 bell cranks can legitimately be of same size since that's the idea behind 135, so the common axis can be in line with mainshaft which is the ideal.

From this we can infer that given same swashplate size, it can be seen that 135 has greater vertical movement of swash than 120.
