    Another NEW Savannah S on it's way in NZ

    in Savannah

    Keep looking Bob, they will be in there, a small plastic bag of countersunk a4 rivets can be hard to find, they are usually in the same box as the big bag of a4 domed. There should also be a smaller bag of a5, also small bags of a3, a bag of a5 countersunk, a bag of a5 longer rivets, a bag of large head black painted rivets, and a bag of a5 stainless steel, so if you find any of those the the countersunk ones you're after will be there too.

     

     

    Zenith CH-701 thread

    Does anyone on the CH701 thread have any idea where I can obtain a pilot's operating handbook, preferably for a Jabiru 2200 engine version?

    I have a copy of the CZAW CH701 POH, 4th edition, January 2003, but for Rotax 912, any good?

    You would need a PDF editing program to modify it.

     

     

    Throttle control

    in Savannah

    Would the standard setup benefit form the gentle return springs?

    Don't know if you could say it is of benefit, just some folk don't like the throttle creeping up all time they haven't got the friction lock done up enough.

    With the standard flexible Bowden cable type throttle, the spring must be strong enough to pull the throttle cable through the sheath to get full throttle. You could easily see a situation where a kinked/frayed /not so well maintained cable maybe could not be pulled through by a weaker spring.

     

     

    5 year rubber replacements after motor runs crappy

    in Drifter

    Posted

    Well here is an update: I looked in the oil reservoir this morning and found my worst fear. White cream on the bottom of the lid. Looks like a blown head gasket:crying:I'm licking my wounds and looking for a head gasket set. If anyone has a link to purchase one let me know.

    Don't know how this happened. You may send your condolences

    I wouldn't jump too hastily to that conclusion. If you have only been running your motor for short periods for test runs then then you will not completely boil out the water in the oil, which will then condense in the oil tank.

    Rubber carb sockets should have been replaced at the 5 year rubber replacement. I would check the chokes levers are completely returning to their stops when choke off and do a pneumatic balance of carbs. Spark plug caps on correctly? Both ignitions on and working? Main jets partial blockage with old fuel varnish can be hard to see without magnification (if you are old like me) Those are some things I would look at before ripping the heads off.

    With a few wet days hindering work I was able to make time for the Sav again and Dash installed with all the wiring and fuel lines completed. YAHOO 001_smile.gif.2cb759f06c4678ed4757932a99c02fa0.gif

    Nice looking dash Guy, tell us about those electronic instruments, what are they?

    Guy, What did you mount your press-to-talk button in? I made a pair of nylon plugs in the lathe but the guru said they are too flat and the button will be too deep in the grip to reach so just before I cut the top off the grip....Well I will consider other options.

    That's what I do, cut the top off the grip and sand it smooth, put on in the stick upsidedown (best side up), get a correct size plastic pipe stopper with push button fitted and put in open end of stick. Works well. Will post a photo if you want.

     

     

    My Sav S throttles

    in Savannah

    Posted

    Hi Rick ,I think sometime ago you asked me about under carburettors trays , I have found a photo of the good one . Please have a look , I believe you similar not exactly same as accessories from Rotax but a bit expensive.

    Hi George

    Those ones look like they would suffer from engine shake, looks like there's maybe been a crack repair where the flange bend is. (See the short weld)

     

    The rotax ones have a continuous curve from the flange so they are rigid with no fatigue point. Only problem is you got to take the carb off to check the bowls, pain in the a$$.

     

     

    My Sav S throttles

    in Savannah

    Posted

    Hello Rick;I am going to equip my XL VG with solid rod throttle controls based on your pioneer work using them; I have a couple of questions about the hardware.

    With reference to your replies to erd72's thread "Throttle Control", I plan to use a pair of eyeball-type sockets at the firewall (Aircraft Spruce 05-00958 which have the 1/4" hole to fit the outer cable sheath) with a pair of A-820 Friction Lock Controls. (An aside: all three North American Aircraft Spruce warehouses are out-of-stock on the 05-12250 "Cable Safe" items with no information regarding re-stocking. The manufacturer may no longer be in business.)

     

    I already have the R&L hand thread Aurora Stud-type Bearings, the CroMo tubing and the R&L hand thread taps for the rods.

     

    My questions:

     

    • After the eyeball mount is secured on the firewall, is the sphere still free to rotate or is it clamped in a fixed orientation?
       
       
    • How is the outer cable sheath of the control attached to the eyeball itself - that is to say, what prevents the outer sheath from moving fore and aft through the 1/4" hole in the sphere?
       
       
    • What was the reason you opted for 6061 aluminum rods for later prototypes instead of staying with the CroMo tubing?
       
       

     

     

    I follow all your posts - along with those of others who have done wonderful things with the Savs - and really appreciate the Recreational Flyer forum.

     

    Regards,

     

    Dan

    Hi Dan,

    1) after the eyeball mount is clamped up the ball is clamped. It is only to get the correct angle on the control cable.

     

    2) the outer sheath is supposed to be clamped up as well when you tighten the eyeball, but I found that it didn't (maybe tolerances on the cable sheath are nominal) so I fixed it by carefully draw filing the flats between the ball halves so it clamped up nice.

     

    3) the only reason was its easier to put a spanner on the hex bar when tightening the locknut. With the Cromo you have to hold it with pliers or vice grips so it ends up looking a bit munted.

     

    When cutting the inner wire to length don't cut it neat to length, leave it long till you're sure. Also don't have the knob right up on the ferrule part at full throttle, always have about 1/2" -1" of s/s rod showing at full throttle so there is no strain point as the engine moves.

     

    Hope it goes well for you.

     

    Cheers

    Another NEW Savannah XL on its way

    I wonder how much extra wait the new nose leg bracket is?

    If you mean "wait" as in time before delivery then Reg usually has them in stock so should be about 3-4 days by expess post bag.

    If you mean "weight" as in how much extra does it weigh, I'd reckon about 25 grams, if that.

    Anyone know where to locate an air box replacement filter? I have Bosch paper filter and they don't make the anymore. Would prefer K & N but can't cross ref.

    The info i have is the original filter is from a Fiat Regata 1.7D so a K&N equivalent would be a 33-2001.

    Check size before buying though.

     

    Cheers
