Kalt 1987

Might have been expensive but I already have one and the pictures are extremely good, clear and seriously profession. Most of the pictures and articles have been transfered to the VRHC site if interested.

Hi all, is anybody interested in Kalt mainshafts. I use to make varous shafts as a method of paying for my hobby but it slowed down a few years ago and I only made bits for myself and mates.The photo is a Baron 30 shaft and the short shafts are KS1B parts I think witch are old stock in my parts box, if anybody interested please let me know.

Hi Tony,

I'm sure there are others that would like to have some as spares.

The 10mm slotted main shafts for sure and I had not even thought about feathering shafts as yet.

I think the GS Alpha and Baron 60 use a main shaft that is pretty simple, just a slot and the holes for the bolts at each end.

10S heads and dampers

I have two different metal rotorheads and neither of them appear to have any dampers in the mounting of the grips. They feel like a solid connection of the grip to a shaft via a set of bearings.

So what is the idea on this? Is it that when these were made they anticipated only wood blades?

What would happen if carbon blades were used with one of these metal heads?

Hi trillian

I use carbon blades all the time.The Kalt heads have rubber dampers at the centre of the rotor head(At least on the several types i have)I think they were designed that way to allow a certain amount of blade flapping to aid overall stability.On my heads the damper is fitted in line with the main shaft just above the main rotor head bolt.

Canopy options

Just curious what other canopies have been tried on the larger Barons?

I have seen Robbe Millenium canopies on a couple gassers and a Hirobo canopy on another ('not sure exactly which model Hirobo canopy).

The canopy on my GS Alpha is in good shape but it is very brittle and has small cracks here and there and I tend to think just vibrations and stress from moving it around will make it worse. I'd rather preserve it and fit something else on there in the meantime.

There was a guy on here making canopies for the Whisper and I emailed him but got no reply. The last post was some time ago so I guess he is no longer on RR.

'Any ideas?

canopies

I hear you Trillian!
I'd be very happy if we find someone to make new canopies for the old birds. As much as I know about Kalt their canopies where crap. Vacuum formed ABS and thin as a dry leaf...My Baron 60EX has some other brand canopy made of fiber glass. Very good quality but still - not available today...I do have two more unpainted of the same type though..
The only other Kalt I have with fiber glass canopy is the Omega Zeus Grand Prix.
I'd be very happy to send all my plastic ones to someone that makes fiber glass ones! Copy and reproduce. I'd need 4 Baron 20's, 2 Baron 50's, couple of Baron Alpha II's....maybe a couple of Cyclone's too...

By the way...got any gears going yet?

Hey there,

Yeah, this is why I don't want to risk any damage to my Alpha canopy because it can either be used to make a mold or at least just kept as a show canopy. I could reinforce the inside of it probably and keep it intact. The main problem areas are around the mounts. I could use two of the same kind because the Baron 60 is exactly the same canopy only it is fiberglass but mine is pretty thrashed and looks very shabby.

The Baron 50 I have really just needs to be repainted but it would be nice to have a spare for that as well.

Regarding gears I was looking at the gears on the GS and the Baron 50 and the GS main gear is just a bit wider, like 11mm thick. It is 88 tooth and I'm not sure how many teeth is the bevel gear. It's unfortunate that they cannot share the same gear but it looks to me like the GS gear would not fit on a Baron 50 even if they are the same tooth count. And my main concern is having spares for the GS.

I have another gear I got with a Baron 60 that is 80 tooth and has a black bevel gear with a finer tooth size. I don't know what it is meant to go to.

I need to talk to the guy here in the UK that was making Kyosho gears and see if he could make something and what it would cost. The other guy in the USA sounds very reasonable but it just depends on how many of the same gear we can all use.

I have been playing with the idea of moulding my own canopies but as of now I don't have the time for such projects. I could also see them made of thick lexan if someone does that. I could do that too myself but again - time consuming...All my plastic ones are pretty worn and cracked not counting the Baron 20 MX NIB
Gears...first the 80 tooth you have is probably for the Baron 60 EX...I'd have to see it to make sure.
Seems to me most of the Kalts have different gears and since I have quite a few of them Kalts, I'd like see someone do them all!! ...dreaming here...
Can it be that hard to make a mould? Maybe I actually should look into it..
Hmmm...

A gear selection

A few Kalt gears here all different

Yeah, me too regarding the time factor. A few years ago I was building movie props and eccentric furniture / art items and I contemplated building a vaccum forming machine to do big plastic parts. But for a canopy, it could be done much easier just by making a platform and then using a regular oven, using the right type and thickness plastic sheet etc.

But that's still a more elaborate project than I could do at the moment.

There's probably a company in China that could make them so cheap but you'd have to order 10,000

My main gear

I am using old Graupner main gears in my kalts as i do not use the bevel drive because i have direct drive gearboxes.86/14teeth.

graupner gears

'Interesting. Can you still get the Graupner gears?

I have some info from another RR member who is using a Raptor tail and gearbox (which just meshes with the main flat teeth).

There used to be a Kalt optional tail gearbox that was very similar in design and gave a higher tailrotor speed as well.

Kalt optional gearboxes

The optional gearbox is what i am using.I dont think the Graupner gears are still around but im sure there must be others that are which could be used.This i suppose is one of the"joys"of flying old helicopters:

hehe...not easy this.
My Omega uses direct drive....but has yet another main gear...
Someday a solution should be found....If I just had the time!

Well, there are a few different gearboxes out there that can be adapted and once you no longer need the bevelled gear then it's going to be easier to either find a gear that can be fitted or have a gear made.

If it's only a straight gear it might be easier to have one cut than molded.
I remember in a discussion on Helifreaks about nylon gears for a different heli, there was someone saying they could make a gear of any description (but we're talking just a simple flat gear).

I was just looking at the helis and parts by Quick, they have a very simple tail gearbox that's just an open metal frame and they have shaft drives for their gasser and larger nitros. But the Raptor parts might be cheaper anyway.

Xcell has also used a similar drive gear with bevelled section for the tail. 'Speaking of Xcell, I'd like to get a couple plain white Canopies because they look like a shape that should suit the Alphas. The thing is, I really like the shape of the Alpha canopy and I like clear windscreens.

I just got a copy of the manual for the K-5 head by the way. When time allows I will start listing the manuals and stuff on my website as well as info on adapting Raptor and Vario tails.

Alternative main gear

I use the Graupner one way bearing assembly which bolts to the original Graupner gear.This is easily adapted to the Kalt as the mainshafts are 10 mm.This would be the way to go if a suitable gear is found as a replacement.One of my Kalts is using a belt drive which does not require a gearbox,just a straight shaft,pinion one end,two bearing blocks,belt pulley.A belt drive tail of your choice at the rear.Researching what you can or cant use is all part of keeping the old heli,s in the air,i personally enjoy this side because i cant just go to a parts supplier like everyone else and have to sort the problems myself.Great satisfaction when it all comes together.The Kalt in the previous picture is using a Robbe long tail boom,with shaft drive(not wire)and 710mm carbons,all tail fittings are Robbe,very smooth running assembly.

The Alpha Baron 60, Baron 30 and GS alpha appear to use the same gear. The drive gear is 88 teeth, same pitch and 11mm thick. So the ratio is compensated for at the pinion. The only difference I see at the moment is that the Baron 60 and 30 have a one way hub but the GS Alpha has a constant driven tail. If the holes are the same then they could all share the same gear.

-Just to add, I have read that earlier versions of the Baron 60 and GS use a different gear. I think it is after 1992/93 that the GS, Baron 60 and Baron 30 use the same one (88/69 and approx 11mm thick white one piece gear). It is part number 31068 in the Baron 30 manual.

slotted shaft thoughts

Here's an attempt at thinking 'outside the box'; I wonder what would happen if you took an 8mm hardened steel shaft and bonded onto it a 1mm thick steel tube with a slot cut on one side?

If one of the bolts at either end goes through the outer tube as well then there's no way it could shift, so it would stay aligned no problem.
