    Hi Mark, I hope that you make a recovery really soon! All the best.

    That does seem strange: not much beefing up for a much larger increase.

    It's good to see you working on your Savannah again. I have hardly been near my build and (due to unforeseen circumstances) was kept away from September till March. Today, I finished by two outer flaperons. Next job, the inner flaperons. I will probably start on a wing next but, after reading this thread, perhaps I will have a look at the flaperon mixer first.

    The increase of 544 kg to 560 kg is only an additional 16 kg. Of course, at the ultimate load factor of 6 G this adds 96 kg before catastrophic failure of the Savannah's structure. Nevertheless, the additional strengthening seems quite substantial for a less than 3% MTOW increase. This makes me wonder if the original Savannah was somewhat 'under designed' in the first place? Perhaps ICP used that 16 kg increase as an explanation to have this extra strengthening added just to be sure?

    ABSOLUTELY!

    Which aircraft did you build, KG?
  12. eightyknots
    Great news Steve!

    Any updates Karl?

    It has been 1/2 a year now and still no word from Peter Harlow.

    Thanks onetrack. I will try this next time that I am looking for specific information.

    It is fantastic to see all this progress Bex. Hopefully you are still making good progress health-wise also!

    Here is a picture of one of the New Zealand tricycle Savannahs with a rudder extension fitted followed by the yellow Savannah which had it added later. This allows you to see the increase of the rudder's surface area.

    The factory may not have a problem with the tailwheel version but they had to make the aeroplane heavier to achieve it. This is a quote from their website: The fuselage has been further reinforced to accommodate the main landing gear that was moved in a forward position. Corresponding with the tail wheel, the rudder has been enlarged to improve the directional control on the ground. This has the effect of adding 12 kg on to the weight of the tricycle version using official ICP website's figures. The tall rudder adds 0.5 kg so the beefing up of the airframe has added 11.5 kg. I think the best thing that ICP has introduced with the tailwheel version is the taller rudder now available as an add-on to the kit. I did buy the tall rudder kit and it adds about 420 grams in weight. This does not include the extra paint that will go on it in future. All up, I estimate around 1/2 kg. Reg Brost developed this and the idea was soon after this borrowed by ICP in the same way they liked Stolspeed's (JG3's) vortex generators which are now found on almost all Savannahs sold. The irony is that the tall rudder kit is sold in considerably greater quantities to tricycle Savannah builders than to tailwheel builders.

    I am very intrigued as to why the outboard tanks shifted outwards without having the weight of the fuel inside the tanks, this being the factor (I would have thought) that would have caused the shift. ⛽

    I have read about the vertical brackets as well ...in addition to the many other suggested improvements for this aircraft, many which are worthwhile. I intend to 'locate' the tanks somehow but I am conscious that every additional improvement adds weight to my Savannah. I wonder which option weighs more: sikaflex or small aluminium brackets?
  21. eightyknots
    I wonder why ICP don't use aluminium tanks like some other kit manufacturers?

    Hi Bob, Shifting fuel tanks is a good sign! ...it means you are flying her ?. I was wondering about which direction the shift is: inboard or onwards? ...also how far?

    So is this: You know, when I was a kid, my parents taught me a riddle. It said, "If there are five frogs on a log and one decides to jump off, how many are left?" And the answer is five - because deciding to do something is not doing it." PHIL BURGESS, former senior Telstra executive.

    Hi Steve ZK, What model Savannah do you fly? ...Classic, ADV, VG, XL or S? Also, have you flown your aircraft on longer, cross country trips ….or just local?

    Is your AOA/LRI a Bendix unit? I have considered these but at present they are pretty pricey. Or, perhaps your instrument is another brand? The Bendix instruments came out on top of comparative reviews when I read about them about three years ago. Perhaps there are more cost effective (but still functionally effective) units on the market than the Bendix. I am not aware of any.
