Yep that is Big Ben !!

Yes, you can buy self drilling/threading fastenets pribably at Home Depot for example. Thanks for wstching.

Hello out there in NS, thanks for watching and taking the time to provide some feedback.

@@rv9flyer13brotary9 Thanks for feedbacn; I'd like to read the report from Wyoming ....

@@jeffrotullstein Have you ever been on the "Rotary List" over the years, as you developed your 13B installation? The list is pretty quiet now as so many older guys have stopped flying, but there is a great archive of information you could search via topics / key words to learn more about such things as "SAG". Because you knew the term "SAG", I imagine you know about the list. Here is a cut and paste of Steve B.'s research (from the archives) re. "SAG": "Indications were that sag was due to preignition caused by the spark plugs. The hottest part of the spark plug is the tip of the insulator. The temperature there is controlled by conduction of heat through the alumina insulator into the base of the plug and by conduction through the center electrode also to the base of the plug. The vast majority of the heat is conducted through the center electrode which has a copper core to help do this because of copper’s high thermal conductivity. As the spark plugs age, salts form between the corroding center electrode and the tip of the insulator. Those salts have a lower thermal conductivity than the alumina insulator so less heat is conducted to the center electrode. As the plugs age, the center electrode copper core becomes porous due to the cyclic temperature change with each combustion event. This reduces the thermal conductivity of the copper core. Those two processes result in the tip of the insulator becoming hot enough to cause preignition at high power conditions. Throttling back stops the preignition. Using leaded fuel appears to cause the preignition to occur with less spark plug time in use. For the rpm decrease (sag) to occur, preignition must occur at both the leading and trailing locations simultaneously. Preignition at only one location actually gives a slight power increase. No amount of cleaning can reverse those changes. Although the heat range of new stock spark plugs is initially appropriate, they essentially become hotter plugs as they age. NGK plugs are colder with higher number. Using stock trailing plugs in both the leading and trailing locations will help. I’ve been using BR10EIX plugs in both locations which helps even more and they have been lasting well over 100 hours whereas the stock plugs would often develop sag at less than 20. Steve B."

@@rv9flyer13brotary9 Yes, I have been reading a contrubuting to the flyrotary@lancaironline list for about 20 years; however, for the past several months I can't access the website. I get "the digest", so have read and responded to your recent posts, in fact I responded about the resistors today, referencing Digikey and Newark ... I have complicated things by using a nickname on KZbin and using 2-3 email addresses ...

Well I didn't do any of the gas tank welding because it's aluminum. The guy I took this to had an aviation welding certificate (expired); he said he would not put water in it because you can't fill it 100% and what happens is the remaining gas is now compressed, making it more explosive. He just leaves them with all ports open for several hours then "Flashes" them with a brief exposure to flame ... I think the exhaust hose is a good idea if pressed for time.

My cruise is 5600-5700 RPM compared to the car at about 2500 RPM. It's the combination of RPM and duration. Lots of Mazda drivers will shift over 6000 RPM but then drop back down into the 2500 RPM range. My takeoff RPM is 6200 (30" MP / 100% power) which I hold until reaching circuit altitude of 1000 ft above ground, then drop down to 27" MP (85% power?) for another minute or so. My cruise MP is 22" (55% power?) burning about 7.5 gph (US).

Nice, glad to hear I was able help you out ...

@@k.c.8447 I did one, keep searching my channel or playlists.

@@k.c.8447 Using 2.85:1 ratio redrive named RD1-C, made by Real World Solutions designer Tracy Crook ... these redrives are solid but no longer in-production; only available on the used market.

@@rv9flyer13brotary9 Yes I have some photos. My exhaust is made ftom 1/4" plate exhaust flanges welded to short pieces of 2" mild steel. The 1-7/8 headers slip inside that and join below in a vee ... the rest is necked up to 2.5" into Aero Turbine Muffler and 2.5" exhaust pipe. All pipes are 304 stainless that I welded myself ...

Yep, going to tarp it in late fall.

It's a morning or evening thing in good weather; never see them on crummy days ... you know where we live ...

@@jeffrotullstein Yes, I do.

He's 2" taller ... maybe doesn't need a step ladder ... lol.

Haha welll I'm always banging my head ... thx for watching.

Yed it does, best to operate on cooler days.

Yes, it gets very hot ... lots of pressure there. Best to run it on cooler days.

Got for it, US gas prices, speed limits and highways are great ... keeo it between the ditchez.

Couldn't resist ....

Cool, I hope Sherbrooke was good.

@@jeffrotullstein It was great. VFR conditions, severe clear.

I started working about 16 hrs per week (Tue & Thu evenings and all day every 2nd Sat) for about 2 yrs, getting the landing gear and the fuselage built, doors on, rudder, elevator, stabilizer and trim system. My book says 2510 hrs on airframe and 608 hrs on the engine install but my first engine was a 3.8 L Ford V6 ... this is the one and only airplane I've built; since you have previous experience you may be able to go faster and plan better. Good luck with your project; it's a worthwhile endeavour. Jeff

Awesome, thanks for the comments and good luck with your own splitter ... Jeffro !!

Yep, supposed to be 20+ face cords. It is 90% maple, the rest is beech and oak. Wow $700 for a full cord is more than I'd pay ... would have to go back t scrounging.

Yes, that was the problem; couldn't draw enough fuel through the dirty filter under load.

@@jeffrotullstein the simplest things sometimes, eh?

Thx, have a safe trip ...

Thx for the comments, tonight's flight was a few circuits to test an audio recording mod ... fun.

Ah, well sweet gum is not a local wood where I live .... but thanks for the comment and for watching.

Intetesting comment because I actually do the same but maybe 1/4, guess it doesn't show in this video ... thx for watching and providing feedback.

You'll have to wait 10 months to find out ...

Thanks for watching ...

Thank you for posting @@jeffrotullstein

Yes, a bit late and yes they are designed for automobiles not quads and they are north of $200 ... this mod cost me about $20.

Yep, was a donated item from a Patreon ...
