Kyosho Caliber 30 & 60 - Concept - Nexus > It’s ALIVE!...Well sort of….

Well it’s been a while since I have posted in the Kyosho forum. I haven’t been flying Kyosho helis since I sold my Caliber 5 after buying a Trex 600 Nitro Pro. I still check out the Kyosho section daily with great affection. My first helicopter was a Caliber 30 and I really liked both my 5 and my 30. My latest project has been resurrecting a Caliber 30 from my spare parts bin. I was going to sell off all the stuff when discovered I had enough stuff to build an entire heli minus about $20 worth of parts.

After getting it resurrected from the dead, it unfortunately flew like at was dead. It definitely was not helicopter I remembered from my earlier days. Now granted, I have gotten used to my 600 Pro with an OS50Hyper and 14 degrees of pitch. It’s a freaking rocket and my 450CF is no slouch either. Even after bumping up to 11 degrees of pitch on the Cal 30, which is a little much for an OS32, It was still extremely sluggish. It also had a very bad case of Woof Poof. So after rebuilding the engine, replacing all the head linkage with the Caliber 4 linkage and replacing the cheap fiberglass blades I had with some nice MAH carbon ones, it is doing a little better.

The problem I have now is that there is still a lot of slop in the head, a lot of which is in the blade grips. I remember having that problem when I used to fly the Cal 30 and had upgraded to the Quick UK grips. I don’t want to spend a bunch of money on a discontinued Heli, so switching the whole head over to the Caliber 5 head is just not worth the money and no one stocks the Quick UK or the Correct ones that I can find. Does anyone know if the grips from the Caliber 4/5 will work on the Caliber 30? I thought this would be a cheep, fun project and I could have a little 30 size to put around with. But like most things in this hobby, the money just keeps flying out the window and I see more “upgrades” coming. If it starts getting good grades in school, I may have to treat it to a nice OS37 and maybe a few new servos. Any ideas on blade grips?

Yes the Caliber 4/5 blade grips fit. You may need the button head cap screws and shouldered washers for the spindle shaft though. The Caliber 30 cap screws and washers will fit but will catch on the blade when you try to fold them. Well they did when I tried it.

I might just try that. It look like the grips come with the washer, so hopefully it will work. Thanks

I had woofing (no poofing fortunately) on my Cal 30 and trying to tune out the slop didn't help. Braced the servo tray , and like magic, the blade tracking issues went away. There's still slop, but hardly noticeable for sport flying and it handles like such a pussycat!

I used some broken trex skid aluminum tube, flattened each end, and secured them between the tray sides and the frame to the rear of the tray- I think there are holes there for the sliding tray option already.

Never, ever, ever, ever give up.

Yeah. I had something like that back in the day. I didn't think about that causing the woof/poof. I did it to me the other day and it about eat it's self.

Here is what I did. I may have to try it again.

I also had these at one point.

Thanks for the tip.

I have a question. What the heck is woof/ poof? I have a Caliber 30 that I just bought so I might run into this problem.

Thanks

wheelnet1, I like the links for stiffening the servo tray. same concept as I used with the flattened-ended alum tubing, but yours is of course neater looking

Woof- the blades or a blade goes in and out of track depending on flight/collective conditions, not good. Make a "whoof"ing sound. Some heli designs have been prone to this issue, there are various fixes. With the Caliber 30, it might be slop in the collective, or loose fit of the washout slider pins to the washout guide (CNC Guide is reported to help or resolve it), or... in my case stiffening the servo tray to the main frame solved my whoofing.

Poof- if Woof gets too severe, and the blade strikes the boom the heli goes "Poof". also bad.

If you search the terms, you can find several threads on this issue for the Caliber 30, and other helis like the Raptor 30.

Not all the Calibers have this issue from what I've gathered, but stiffening the servo tray, and reducing slop in the control system is always a positive thing.

Never, ever, ever, ever give up.

Woof is a noise that you hear when the blades go way out of track.

Poof is when they go so far they hit the tail boom and the helicopter explodes.

Luckily I didn't have the Poof, but it was close.

The Caliber 30 is not known for having this problem. I wouldn't worry
about it. Like I said this bird was made from spare parts, although most of the parts in the head are new, including all the linkage. The grips are no telling how old and the servos are the first ones I ever owned. They are probably 6 years old or more and probably need new gears. I have a few places where the problem could be coming from. I was also flying cheap blades, which have been replaced with MAH 555s. I have only 1/2 a tank on the new blades and my tracking was way off. So I'm still trying to get that dialed in.
The only cases of Woof I've heard of involved the slide block wearing out. Some people have replaced the stock plastic one with the aluminum one from RCHeliworks. I flew a Caliber 30 for year without any problem like that.
Don't base anything about the Caliber 30 or any of the Caliber series on this Heli. It's was just an inexpensive way to get another Heli in the air. I just have to work out the kinks.

Thanks for the explanation guys.
I'm still new to nitro helis and in the 400 electrics it's more like Wiff-Piff!

I've just gotten my brand new 1983 GMP Cobra 50 flying and am loving it but that's my first nitro bird and I have much to learn.

Thanks again

The servo tray from the Caliber 4 will drop right into the same place as the one that comes with the Caliber 30. The Caliber 4's tray has the stiffeners built in....

I think it costs something on the order of 5 or 6 bucks.

Thanks Dave.

I have it on my wish list at HeliProz. I meant to buy it with my last order, but forgot. I'll probably pick it up next time I make an order with them. I just have to find time to go fly and see if the changes I've made have fixed the problem and given me a little more lift. If I can get it flying the way I want, I'll probably put a 37 in it to give it some umfff.

After I get mine up and flying for a while I want to convert it to a 50.
Is this a bad Idea?

It's probably NOT worth the time, effort, and money to convert the Caliber 30 to a 50 sized motor. Assuming you have the motor, you still need to buy the Caliber 5 belt, boom, motor mounts, flywheel, and a set of 600 mm blades. I'm not sure if the stock Caliber 30 clutch will work with the 50. By the time you buy the individual parts, you'll have nearly purchased a Caliber 5 kit. I don't know what servos you have in your Caliber 30, but you might need to upgrade to some better ones if you go to a 50.

For a nearly dirt-cheap price you can buy the Caliber 5 kit (something on the order of $270), complete with pretty good CF main blades and a serviceable 50-sized muffler. This kit is actually a much better value than the Caliber 4, and flies much much better. Add the EMS linkage kit and an MP5 or other after market muffler, you'll have a pretty darn good 50-sized heli.

And seriously consider an Align 600N Pro if you're in the 50-sized heli market.

BTW -- If anyone's looking for a Caliber 5 -- mechanics only -- no motor, blades, or electronics -- and nothing bent or damaged, I'll seriously consider selling mine. It's got the EMS linkage kit installed and the optional pinion that makes the gear reduction more suitable for a 50. PM me if you're interested.

My Caliber 4 with and OS 37, CYE MP2, but no electronics could also be had if anyone's interested. This would be pretty much install your favorite electronics, fuel up, and go fly.
