View Full Version : Need Help on my Hirobo

Hi Guys,
Please, I need your help identifying the specific model of my Hirobo. I purchased this out of eBay and the seller told me it is a 60 Tsurugi with Eagle head. The engine is .61OS MAX SF. He cannot provide me with a specific model. It was described as RTF, but upon complete dis-assembly for inspection and cleaning.... I found out that the heli is in really bad shape:
- Mavrikk PRO G4 blades: one blade is 1/4" shorter and the other blade
has cracked on the middle.
- flybar is bended
- most of the bearings are loosed and rusted
- loosed screws and some are missing
- flybar bearings are stucked
- wirings are messed-up
- timing belt - lower part of the belt are stripped
- 9T pulley - also stripped
- engine has no gasket between manifold
- canopy are all cracked
- and many more to list.......
Anyways, after the general cleaning and some polishing, I managed to make the Heli in tip top shape.
My other question is, I've ordered a new set of Mavrikk PRO G4 700 blades. Is this a right size for a 60 class heli, or is it too long? If not, I might send it back to Heliproz and replace it with 680mm.
Please, if any one of you guys has any information or Manual for my heli, I'll be happy to buy it.... cause I need to purchase the 9T pulley and the timing belt and some more parts (but I don't have the part numbers). Please see the pictures below...
Thanks in advance,

THat doesn't look anything like the head on my old eagle did.
If he sold it as RTF, then I would be seriously considering a report to Ebay, negative feedback and taking away his birthday.
The Tsrugi is the predecessor to the Eagle. I think the Eagle came about in the early 90s. After that came the Freya. I am not sure if you will be able to get parts for that machine.
I would not fly that machine with out getting a PCM receiver, aluminum frames will glitch like crazy if even one screw comes loose. Also those 537 servos are no where close to being up to the job. I would hesitate to put them on anything more than a 40 size trainer airplane. They are JRs "standard" servo, and do not have the torque necessary to handle a 60 size heli.
Also your description of the siezed bearings would definitely warrant a look into the insides of the engine to see if it needs attanetion as well.
It's certainly not a Eagle (1998 onwards)
Would it be an old Falcon?
(I've never seen one)

Hi guys,
I'm nooby in heli world, I spent most of my time with monster trucks, buggy and on-road nitros...
I thought I got a good deal out of this heli, I reported this seller in ebay and paypal because it took over two months before I received it. But then, I was also surprised when I so the condition of it. The bid ended @ $525 + $55 shipping... but since I didn't recieved it on time, Paypal returned my money. I re-send my payment, but I only pay him $480.
This heli came with a JR XP8103 transmitter, Hangar-9 starter. For $480, I think it is pretty much a good deal.
The engine is the first one I've worked on... and it is in good running condition now... still has a good compression, but no more pinch on TDC.
Ivan, you're right about the glitch... I'm getting too much glitch already just programming the radio.
Anyways, I'll just use this for practice and improve my hovering. If ever I crash this thing... it'll go straight in the trash bin.
I managed to purchased the flybar bearing @ Heliproz.com by browsing the Hirobo parts. I just used my digital caliper to get the right parts.
So far my only problem is the timing belt and the 9T pulley. I don't know how to measure the belt.
BTW, is a PCM receiver will work with XP8103 radio?
Thank you very much for your help....
You should be able to enter the setup menu on the radio and select PCM. There are two types and one won't work with the other. Just get a PCM receiver, and select that type (S or Z) I am not terribly familiar with the 8103, but on my 10x, it is under "MODUL" to select the modulation type.
As a side benefit, you can program a fail safe. On helis program everything to hold last position, except the throttle which should be set to idle.
Usually the belt will have some numbers on it. I think Hirobo used BANDO belts, so if there are still numbers on it, you can find them fairly easily.
FWIW, I would stay away from EBay for helis. 90% of the ones I look at there are a scam of some form or another. Stick to the Helifreak and RR classifieds. They are pretty tight communities that don't put up with much in the way of selling junk. Also, if you ever get to the point you want a better heli, you might consider the EVO 50 or the Raptor 50. they are pretty popular, and you can get parts for them. If you want to stay in the .60 size the Freya is a good machine which is a great price. You still need ot invest in decent radio equipment, new blades, and so forth, so you might just start saving the extra for a good heli.
Even if the Tsrugi was n pristine shape, it is still probably 20+ years old, and helis have come a long way since then.

Yes, the settings is under "MODUL" also. BTW, do I need to replace my TX module in order for me to use a PCM type receiver?
It's nice to invest with a decent radio... cause they don't crash like helis... :mrgreen: .... but the 10X, I don't think I can afford that kind of radio.... it is too much for me ($,$$$.$$).
I've purchased a Mavrikk G4 700mm blades... do you think is that too long for a 60 class heli? I tried to return it to Heliproz.com and replace it with 680mm but they don't respond to my email.
About the belt, there's no number... maybe I'll just count the number of teeth and contact Hirobo... :idea:
Again, Thank you very much for your help and tips... I really appreciated it.
700s will work ok with a 60.
If the module says PCM on it you should be good to go. I don't think JR made a module that didn't transmit in all configs.
Contact Jeff Green at Altech, the Hirobo distributor in the US. He may be able to help, and always seems to be more than willing.
FWIW, any time I have wanted to return something through Heliproz, I have gotten the same runaround. It usually ends up with them telling me they aren't responsable and to deal with the manufacturer. Had it happen with a set of mismatched NHPs, an OS engine and some other small stuff. They have an excellent selection, and ship fast and free, but after the sale they are very iffy. Ricks on the other hand has never failed me in any way.

Hi Ivan,
I'm sorry if I am asking too many questions.
The module says:
PCM
Pulse Code Modulation
FM
NET-J72P
Yesterday, I was running a test on the engine (without main blade). I've set the main needle to 2-1/4 turns out. It idles good but after a half throttle burst then back to idle, the engine dies. I'm gonna lean the needle setting and will try again. Upon testing, I don't get a single radio glitch. Also, the vibration is very little. My only problem is the belt, it got shaved again and it was stripping so bad.
BTW, could you please give me the specific site to contact Jeff Green. I hope he can help me with my timing belt and 9T pulley.
About the 700mm main blade, the reason I asked you because I heard that you cannot use more than 680mm main blade in Hirobo (not sure about specific model) because Hirobo has a longer or wider head.
Anyways, next time I order at Heliproz... I'll make sure I will order the right parts. I got some order from Rick's too and I don't have a problem.
I was just curious about the 700mm from Heliproz that thinking that it was too long for my heli.....
many thanks,
-=Alex=-
680s were the standard size on 60 size helis. Either should work ok. If the 700s are too long they will get into the tail blades.
If your module says PCM, then your transmitter will transmit it.
Don't run the heli with no blades, it is too easy to over speed it and tear things up. Plus a loaded engine will require a different mixture than a free running one.
Google Altech Marketing to find Jeff Green, that is the way I would do it.
Hirobo's have traditionally had wide heads and used shorter blades
I doubt that you can safely swing 700's on her
Even the early Freya 60's ran 660 to 680

Thanks for your help guys... :)
Ivan - I'll try to find the belt and pulley first, then i'll purchase a PCM Rx.
even though I don't get a glitch during my test, I still want a glitch
free receiver. BTW, I can't seem to find Altech Manufacturing...
I found Jeff Green's email adds (jeffg@modelrectifier.com) but
it doesn't exist anymore.
jafa - if Heliproz doesn't accept returns, I'll just sell it to ebay. I got that
for $99.99. I might sell it with free shipping, just to get rid of it.
Maybe i'll just get the V-blades (680mm).
I'm so disappointed with this heli... :( :( :(
Regards,
-=Alex=-
I think you will find that it will fly rather nicely
It's not a 3D gun but it will fly aerobatic real smooth and graceful and locked in
It will reward your efforts I feel
At the very least, you can use her to learn piro flips :bomb:

The website for the Hirobo importer is www.modelrectifier.com, it is in NJ and they will be all the help you need getting the parts. There is a phone number listed for customer service, the person that will answer is Tim, a great guy as well as Jeff. Good Luck Tom :D

jafa - the heli is not 3D ready or not designed for it, that's fine with me,
anyways, I'm not ready for 3D as well... :oops:
I spend most of my time now with sim(g3.5)... and can do some
3Ds.... just not sure if I can apply it in real world... :mrgreen:
tommy - thank you very much for the website. I just send them an email,
I just hope that they can help me with it.
Have a nice heli-weekend,
-=Alex=-
Yup, sure, but you will be able to do loops, rolls, half loop into half roll,
stall turns, as well as flying inverted, forwards and backwards.
That's a lot of valuable learning experience!

That heli looks like a Condor/Eagle series. Probably 660's are the longest blades you can use. From the pics the head looks like the SSR series but could also be a Kalt head. We still carry parts and I am sure if there is something that is discontinued, we can find a way around that part with other parts.
Anything else you are looking for?

Hi Jeff,
Is the manual still available for my heli? I got few more things to order but I don't know the specific name. So far, timing belt and the 9T pulley are the major parts I need.
I got email from Heliproz.com and they will accept my main blade for replacement. Jeff, do you think 680mm blade is ok to use. I've search their website (heliproz.com) but they don't have a 660mm size Mavrikk blades. MAH, V-Blades and Radix doesn't have 660mm either.
Anyway Jeff, if you could give me the part number for the belt and pulley so I can place my order @ MRC... I really can't wait to make this heli fly.
Also, I want to thank everybody for the help. :D :D :D
The 680's will be fine,
but if the OS61 struggles just limit the pitch to +/- 9 degrees
The 680's will be far better for learning autos :lol:

Thanks Jafa.... the 700 is on the way to Heliproz for replacement (680mm)... :D :D

Hi Guys,
I'm back, since my laptop crashed first than my heli. I want to thank everybody for putting this heli together. After a few months of waiting for parts and with my very busy schedule, I finally tested the heli and fired it up last Saturday. Everything is balanced, no vibration, engine runs good and ready for take-off.
Unfortunately, with so much excitement, I did not check the TX setup. It was setup for my G3.5 sim. Everything is almost the same setup, except for the left and right movement. The heli tilted on one side damaging the tip of the main blades, pitch servo arm poped-out and most of the rod-end has enlarged. After inspection, I run it again with no intention of taking-off. The blades are not causing any vibration and it seem still balance. Do you guys know where I can send this blades just to fix the scraped tip and at the same time balance it. Or can this be done by myself? I was thinking of sanding it down to smooth the tip, but I don't have a balancer. Do you guys have any Tips and Tricks so I can do it myself.
BTW, my heli has no specific model cause it has a mixed parts on it. I've downloaded the manuals for SST Eagle, Tsurugi and Freya and I found some of the parts of every model in it. But the main chassis is Condor as I found it on eBay that is currently for sale.
Thanks,
