Those pipes of Steves are not stainless. Their carbon steel and he is offering them for sale.

ahhh.. my bad.  They look like stainless... and they looked a bit burned up. 

:BC:

 

Maybe that's from annealing after welding?  EDMO

yes it can.. you just use 309 rod when welding SS to carbon.  We weld it to carbon almost every day here at work putting on gauge valves etc.

Speaking about welding stainless steel, and from someone who knows very little about welding, and ain't afraid to admit it ;-)  Just for the fun of it once I brazed a couple of pieces of SS together.  I don't know what type of SS it was, It came from a SS kick plate off a door.  I was surprised how well it held.  Never used it on anything, but maybe could in the future??  Any thoughts Leni?  JImChuk

They did a lot of brazing in the past, but again, it all comes down to the grade of material and what the intended purpose of it is... I welded some aluminum together with 309 SS rod.. welded like shit but it held :lol: 

I don't think I would put a whole lot of faith in a high strength area brazing it together but for small brackets etc I don't see why not.

I was on the phone first thing this morning and they are no longer available. I was told they had one coming in next week so I put it on back order. Guess we will see if that happens. Wish me luck.

Give tony up at Twisted Metal Racing a call.  I got one from him with a clutch last month.  I got a great deal with the can exchange rate.  Sounded like he had a few more.

You can use a single gauge and then use a 4 position switch to switch from the one probe to the next.   You can even wire the switch to control the EGTs and the CHTs going to different gauges or opposite sides on a dual gauge with the one 4 position switch. It's actually got 8 connections on the back, but only 4 are wired when you get it.   That's how I had my Avid MK IV with a Jabiru wired up.  JImChuk

I rode in that 35 truck from 41 to 45, then my Uncle came home from the war and one day he was driving it and a tie-rod came loose and he crashed it head-on into a tree.  I never saw it after that.  EDMO

Looking good Willis!

 

Just make sure you do a Weight & Balance on that setup before you fly.

Thinking she might be a little tail heavy with the Chevy mounted in that location.

Which direction? I think it's different depending on if it's upright or upside down but I could be wrong.

Thanks Joey ,I should of mention that in my case the shaft is at the top so it takes the 6.7 oz its takes quite a bit less if its on the bottom, I dont have the rotax book handy to know the exact amount.

We got the Rx1 running and its sounding pretty nice, the one problem  I got is the handle bar warmer circut has no off switch its either on low or high, thought it would be cool having a heated grip on the stick till summer came lol,guess we will just install a resistor. I got a small video but guess its to larger to upload here and cant figure out you tube yet but ill keep trying. By the way does anyone know the drying time in between coats of poly spray,hard to find any info on it, the wing extensions are done and ready for spraying

Subject to temperature the manual says 15 minutes between the Poly-Brush and Morning to Afternoon for the silver Poly-Spray. Best I could find...

The AZ Yamaha Avid Flew yesterday for the first time. 

I'm down in AZ for the month (payson-phx area).  Plan to meet teal and check out his adapter while I'm here.  Can you PM me if you think the AZ Yamaha Avid owner would be open to showing off his machine?(assumimg it is somewhat nearby)

Sure would be cool to see that!
