Hi all monowheel drivers,



After landing on a mountain strip today I noticed I had some trouble  

controlling the aircraft on roll out and tight turning on the  

parking.  The next landing on another altiport was uneventful but  

again I had trouble tight turning to the parking spot.

During the preflight check for the return flight, this is what I  

found:  the starboard ring attaching the cable of the tailwheel fork  

was open and was barely insuring a very loose connection. See attached  

picture.

I am afraid that if that ring had become fully disconnected, I would  

have crashed into the wall of rocks on the left side of that runway!

Lesson learned: check that tailwheel control cables carefully before  

EVERY takeoff.

Of course I am thinking at some solution to insure a safer connection  

of those cables.

Hi Remi,



Another way to attach the cable is with a shackle (AN115) and clevis pin. 

This is working well for me so far.

Glad to see it did not let loose completely!

Hi Remi



Glad to hear that connector didn't let go all together.



Some ideas:

http://www.europaowners.org/forums/gallery2.php?g2_itemId=27732



**I am using stainless connectors that could pretty much be used as a direct replacement of the spring clips. I have a pic of McMasters page in cat. with part number. Item is made in France, very nice quality.

**If you need to make another cable, take a look at my 3 Nico, 2 cable alternative to 1 cable. If you go this route first nico the third nico, then hang a 5 gallon can or kerosene or similar weight to load cable when doing nico 2 and 3.

**I made some cone washers to help stop point loading, they work great

**I ripped off Grahams aluminium tailwheel stop

**I incorporated turnbuckles on tailwheel drive, one side with an eye and the other with a clevis

**** This is a little off topic, but not much!

I mentioned this before, if you have turnbuckles to adjust rudder cables and have not addressed their affinity to tangle if you release pressure from return springs, I believe this is an accident waiting to happen.

Resolution is simple, I used two pieces of heat shrink.



If anyone has turnbuckles for rudder cables I urge you to release tension by lifting rudder pedal just a little while observing turnbuckles. When they tangle it limits the side that tangles rudder travel because the other rudder pedal acts as a stop when going aft.

I would not want this to happen on a trigear, but on a tailwheel plane all I can say is "yikes".

Remi,



Loose the clips!  Replace them with AN115 Cable Shackles, Clevis Pins and a Cotter Pins (split pin).

Hello Remi,

Yes, I had the same problem 9 months ago after about 80 hours. I also

noticed poor steering and found the same problem. I emailed John Wheeler

and he told me that they have now changed to a mini U bolt (like the

u-bolt and screw pin used to secure the safety chain on a trailer) to

connect the cables to the tailwheel assembly as they have seen that

problem before. Maybe those wire connectors should all be changed.



Regards,

Keith.

I used these screw shackles as a replacement.  More than enough strength and

not too expensive.

Bob's right. This has been a common problem over the years. Use the AN115 shackles.

Hi Guys,  

   

Just a wee note on the Single carb operation. I have a 912S in my monowheel and had an experience which may shed a little light in this.  

I was opening up to take off after a successful run up check and the engine would only give me 4000 RPM instead of the minimum of 5500 RPM I was expecting. It also sounded a bit rough.  

I aborted the take off and started the search for the problem. To cut a long story short a crescent shaped piece of rubber from fuel hose about 4 mm long had blocked the port carburettor main jet completely.  

I removed the main jet and tried to pass fuel through it and it was completely blocked.  

Thus I can say that a Rotax 912s will give 4000 rpm on the starboard carb only. I am sure it was not doing the engine much good and  but I guess it would have provided enough power to get me out of trouble.  

Good to see so many of you at Sywell.  

Safe flying

Thanks to those who have made suggestions for the replacement of the  

clips. I like the  Shackles + Clevis Pins solution.

Attached are two pictures of my temporary fix.

Hi Ron,



Thank you for your suggestions. However, having no tail wheel stop is  

not good. While pushing your aircraft backwards, the tailwheel will  

turn 180 degrees or more and your rigid turnbuckles will be  

dangerously damaged. Same thing may happen when landing in a crosswind  

with the rudder (and therefore the tailwheel) deflected. When  

contacting the ground, the tailwheel is violently pushed to the  

opposite position and again your turnbuckle may be damaged . The  

Singleton stop is a lot better than the original XS stop (a rolled pin  

which breaks after a few dozens landings), but as I saw several  

Singleton stops damaged by the beating they take, I designed a  

stronger copy (see attached picture).



Regards

Remi

Remi,



Bob may have been using the colloquial phrase "ripped off" to mean  

that he copied Graham's design rather than that he removed it.

Hi Remi



When I mentioned I "ripped off" Grahams designed of his tailwheel stop, I meant that I copied his design.



I did in fact fabricate it from 7075 Aluminium that is quite robust.

don't forget that its better to bend the tailwheel stop than bend the leg. That's why I used soft aluminum

Hi Graham,



That is exactly what I think: a design which is being copied is a good  

design!

Hi Ron,



Sorry for misunderstanding!

Material is some sort of aluminum alloy. I can't tell you more as I  

used a piece of material I found in a trash on the airport. It works  

fine!
