That's what happens when you break thru the 80kt barrier.

I remember my grade 9 history teacher telling me that he saw Sabres being sold for $60k in flying condition. This would have been 1986 or thereabouts.

The oil cooler threads are aluminum themselves, I'm pretty sure.

Yep, although they are 13mm thick. I've only got 16mm total on the threads and I need 6 for the top nuts and another 1 for the bracket, leaving 9mm. So I reckon Blueadventures is right and I should just get some scrap 6mm ally and tap it out.

I've found a possible source - https://www.mxstore.com.au/p/Bolt-M22-Locking-Axle-Nut-and-Washer/BMAXN22?gclid=Cj0KCQjwmtGjBhDhARIsAEqfDEfkXphi3afbMAkbixo6yRbsqsag2c60xS7D1yKceZ00IROsfw6G7hwaApr1EALw_wcB - just messaged them to ensure the pitch is 1.5, if so I'm laughing as it's free postage over $20.

Hey OT, thanks so much for trying - that sounds like a lot of effort, I appreciate it! I may have to take Spacey's advice and cut some full size ones down. Thanks again!

Yes, a number of the sites I was looking at trying to source these nuts are woeful. A search function that lets you set the variables of the item you're after is always best.

These types of videos are usually cut and dumbed down, so it's likely the actual craftsperson checked the curvature out of shot. Mind you with the accuracy of that duplication process, that check may not be necessary. As long as the sanding is even over the whole blade it's fine.

Possibly covering the slots left by the slat removal? But I thought they just ground the brackets off close to the skin and left them like that.

I watched both. But yes that copying setup is amazing.

Thanks OT but I got through to their checkout and they charge $25 shipping, bringing it to $42 for 3 nuts. How can the Chinese send them from the other side of the planet for $4 postage??

"Do not exceed 30mph during first 100 miles", yet "Avoid use of low gears"??

Hey all, I need to source 3 of these buggers. They seem to be made of rocking horse poop because I can't find them anywhere online (except stainless from China or huge postage from UK). Spent some time in Nuts & Bolts Tasmania this morning and they only had full size ones. The ones I need are thin - lock nut or half nut - only 6mm thick. Anyone know where to source these in Aus? Apparently some 125 Honda (postie bike possibly) has them as axle nuts, I'll chase that angle up on Monday. Thanks, Marty

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
