    Welcome Pat! Good to see another plane with slats (I'm building a Zenith CH701, very similar to the slatted Sav).

    Having 12 months is better than 10 when you have 4 seasons. Plus it pretty well goes into 360ish days.

    I don't see how you can get around the undeniable fact that the Earth takes 365.25 day/night cycles to go around the sun. So you can play with breakdown of time periods within each day unit, but its hard to decimalize days and years.

    The bit about risky sporting activities is not the same as road use in choice, demographics or population. By that I mean if you want to do skydiving that's your clear choice, you're fit and well and trained in that activity, and there's a few thousand of you at most. However if you want to get from A to B then whether it be on motorbike, car or bus, you're without choice a road user, you could be any age and health condition and there's millions of you. So to protect this large number of citizens the state has road laws which are pretty reasonable really.

    No man is an island. Seat belts and helmets save lives but also lots of public health dollars and medical care.

    Good article. Amazing how many pilots they have. https://www.theguardian.com/artanddesign/2023/may/22/its-almost-spiritual-the-female-pilots-connecting-remote-alaska

    Thanks Mike - so no rubber hasn't caused any problems with vibration?

    Made the mounting bracket for the oil cooler. It fits on the two spare M10 holes on the gearbox. I thought it could be top mounted but there's too much flex in the vibration isolators, so I'll have to find a way of bracketing the bottom too, probably to the radiator front mount.

    Standard Rotax 912uls.

    Thanks, I'll follow your website with interest. Can't wait to see the Viper finished!

    Hi all, I've never plumbed oil hose in before so wondering what the options are. When I go looking for fittings there's a million different types out there from Aeroquip, AN, straight end with a bead, etc. When it comes to hose there's people using black, blue, stainless steel braid... Is there a specified type of hose and fitting I should be doing for oil line? And size? What should I avoid because it needs special tools? Any advice, as always, appreciated! Thanks, Marty

    Probably a vinyl wrap I reckon.

    Nice grip! I hadn't thought of putting one on the flap handle.

    Well then it's a damn good thing you checked! Said item can be delegated to the passenger, for the starboard side. If the nosewheel is gone you're in trouble.

    Why is it retiring??

    I think it was a throwaway line by the instructor as one of the items on the checklist was "undercarriage" - obviously for those aircraft that have retracts, the 172 didn't, so he said "just look out the window and make sure the wheels are still there!" (Obviously not suitable for most low wing aircraft!) If I remember right, it was "BUMFHH" - Brakes, Undercarriage, Mixture, Fuel, Hatches and Harnesses.

    Cruise = snooze!

    Even in the C172 part of the pre landing checklist was to look out the window and make sure the wheels were there.

    It'd be much less work for the cabin crew too. Might be a problem if you need to get everyone off the plane in an emergency though.

    The thing is, urgent face to face meetings just aren't as vital these days, so I'm not sure how the business case for passenger hypersonic stacks up. Companies could invest the cost of one return flight into dedicated high resolution VR meeting rooms and not have to travel at all. As for holiday travellers, yes it's boring to spend 27 hours getting to Europe, but it's a lot more gentle on the body than 6g.

    If Ryanair are running it, you'll be able to purchase less G for your seat.

    I'm building my 701 with a header tank, but will be plumbing the return line to one of the wing tanks. This should avoid that issue and I believe Savannah specify return to the wing tank rather than to header, is that correct Bob?

    Thanks everyone - think I've got it sorted now. Did some more holding in position, and yes it's best with the oil cooler at the front and the radiator parallel with the front exhaust runs but offset from centre to avoid the exhausts. Pics below show - oil cooler is dark, radiator in aluminium colour. That's not exact position but close. I'll have to jiggle it precisely then I can draw up the mounting brackets required. Luckily there's the M10 holes either side of the gearbox for the oil cooler (which only mounts at the top - no provision at bottom for any attachment), and the front and rear holes at the bottom of the engine for the radiator. The rear holes are used for the engine mount, but if I put an aluminium spacer inside the engine mount recess then a longer bolt can also attach the radiator bracket on the outside.
  24. Marty_d
    That's not a bad idea Bob - move it back a bit under the exhausts and put the oil cooler up front. Thanks!
  25. Marty_d
    Well I would, OK, but imagine the weight of the extra water and hose...
