Hi = Chris,

Don’t you just hate it when = you’ve only yourself to blame? {:>). Other than the dinged radiator, = it appears you are getting things sorted out, Chris. A tough, long process it = can be as you can certainly attest to.

You are clearly getting very close = to that first flight. Take your time, no hurry (says I {:>)). = Looking forward to more reports.

Subject: [FlyRotary] = Turbo Velocity progress

I got my turbo manifold welded up (thanks to a friend on the field), turbo and waste = gate installed and this last week I got the intercooler, BOV and piping all plumbed = together.

I also removed a big ol' fan that = I think was restricting radiator air flow that was located on the "in" side of the radiator and replaced it with two smaller = fans located on the "out" side to pull air through the = radiator.

I pushed the plane out of the = hangar, chocked her up, advanced the mixture to full right, gave it four spurts = of prime and she cranked right up, dialed the mixture to = twelve o'clock and it ran pretty darn smooth. WOW, is it QUIETER!!!! REALLY really Quieter. Straight pipes out of the rotary = was having the military jet jockey's coming by to see what the noise was = <g>

All looked good...well, since the building Gawds like to have fun at my expense after running for a = few minutes I noticed a nice stream of coolant shooting up into the = air. Sigh. I must have ding the radiator when I pulled out the old = fan.

Anyway, I did shut down and just = to see what would happen, I started it up and shut down a few times. It = started fine each time (this had been a problem in the past). No more = primer needed and the mixture was just past twelve o'clock. The leak was not a = real factor for these short runs.

Here is a link to it running at idle. Note no leak since the pressure had not risen yet. = Please forgive the artifacts of the prop as this was taken on my phone. I = am not as close to the prop as the artifacts make it appear. I will try = to remember to take my camera out once the new radiator is installed and = get some shots of the install and plumbing and better running = shots.

I did apply some power twice and = got it up to 39 MP at just over 6000 rpm for several seconds. I was not = able to test much due to the leak. I pushed her back in to the hangar and = removed the bad radiator. I could have messed with getting the leak fixed, but the reality is the PITA factor would have = bugged me (find a shop, perhaps have to find another = shop<g>, have them repair and test, charge me, maybe got it right, maybe not....etc) = so I just ordered a new one for $250 from Summit. It should be here in a few days and delivered to my = door.

I occupied myself the rest of the evening doing some clean up work that was much easier with the radiator removed. I also made a support bracket to help support the turbo = so all the weight is not on the turbo/exhaust = manifold.

Even though I am annoyed at = the radiator leak (can't blame anyone but myself), it was a great two days = of progress overall. It was great to hear the plane run so much = quieter and to have it start and RESTART all but effortlessly. =

Also, I got = my Dynon Skyview mostly installed. The AHARS is a combination of = the magnometer and the pressure sensors so you have to mount the unit in a magnetically neutral area AND run pressure lines to the unit. So, finding a good = location in a canard is posing a challenge. The Dynon looks = really kewl though.

I am waiting for a buddy of mine = to finish some of the more complex wiring tying my King 125's, Transponder, audio panel and intercom. It is his line of work and = allows him a break from his RV-7 with a Soob build <g> =

Anyway, so it = goes.

All the = best,
