Hope you had a nice RV weekend. Monday’s issue is out a little early (job3 needed a meat servo). Didn’t get to fly the RV this weekend, but did get the yard mostly squared away and we got a lot of rain. I’ll take it!
Have a nice Monday.

rmartingt -7 Milestone
Did a thing today... got a few tweaks to make and a couple minor instrumentation bugs to rectufy but it went well.

RV-7 #74017

Return line swivel fitting - hope the line is well stabilized between that & engine as there is only an o-ring inside that fitting & wouldn't do well if line vibration is present. Good point on the vibration. I may yet (probably will) revise this concept a little more. I wish I had some hoses...

Hartzell Raptor

Recently flew a two-blade Raptor about 10 hours on the front of my RV-8. This is the late model carbon prop specifically designed as a much lighter alternative to the 7497 aluminum BA. That's not to say the 7497 was copied in carbon. It's a clean sheet design to optimize properties, with a...

Aileron alignment

Been struggling getting my ailerons and flaps aligned. Thought I had it until I found out my flaps weren’t aligned correctly with the fuselage. I then cut out a wing cord template, see attached picture, and it points to the aileron being a good inch higher than what the wing tip alignment board...

During one break in flight, the #1 cylinder started indicating high EGT. Headed to base and inspected intake system suspecting an intake leak. Replaced the intake boot...

An extra hole on wing top skin

This hole is on the outboard wing top skin. What is it for? Its location seems symmetric to the tie down hole on the bottom side skin. Is it designed for a possible tie up 😄? Should I just rivet it? The KAI didn’t mention it at all.

Dang…Cracked My Canopy!! 😉

But hold on…it was my “practice canopy”! When I bought the untouched F1 QB kit from Vince a little over a year ago, we found that the canopy had been stored in some way that it developed a big divot in the top - like someone stored it upside down in a hot place while it was sitting on a 4x4 or...

New "Ti-Down Rings", Lightest, Strongest, with Locking Jack Cups

Tired of holding my breath every time I lifted an airplane with wing jacks, I set out to design a wing jack system that would be positively locking. If I'm jumping in/out of the airplane, if the hangar door is open and a breeze comes through, or if an overzealous helper leans across a raised...

Help with weld-on-#4 to reattach canopy corner

Well, the corner of my canopy snapped off, about a 1" square piece. From searching here, it looked like the consensus is that Weld On #4 was one good way to reattach it. So far I have been unable to get this stuff to work. Directions just say to apply it, assemble while still wet, initial bond...

Behind the panel photos showing harness routing? Dual G3X with AP and Garmin GPS

Howdy folks! I'm working my way through KAI section 42PiS for the dual G3X Garmin panel and I was wondering if anyone ahead of me had pictures of the wiring layout? There are a couple photos in the plans but anything with some other angles might help me visualize things. Perhaps someone could...

RE Oil Cooler Shutter …..wirejock 7A
I installed a butterfly valve right in the baffle behind #4.

Oil Cooler Shutter

I see both Vans and Anti Spat Aero has these for sale. More detailed description with the AntiSplat version. Has anyone compared the two and is there a clear winner or are they pretty much identical? Going to install one to control my oil temps.

It Can Be Done!

Three days after starting to make plexiglas dust and having fit TWO canopies, I am happy with the slider canopy fit on the F1. Lessons learned? Read the instructions and look at the pictures four or five times…and then use a practice canopy to precede work on teh final one….both lessons lower...

Meditations on a Grounded RV

I. Teardown What does it mean to savor the fast, fleeting, and final hours on the tach before the engine goes idle and the last puffs of burnt fuel begin to fizzle into a wide and far-reaching silence? What sense does one have of eternity when, with a single glimpse, there is captured high...

POS-12 incorrect output

Hi all, We installed the PH Aviation PHA-01 flap motor today. I had also purchased a RAC POS-12 to drive a flap widget on my Dynon HDX. In addition to the 2 wires to power the motor there were 3 wires not connected to anything and marked GREEN, ORANGE and BLUE....Bingo! With the flap motor and...

12iS Air Box Connecting Hose Replacement

I wanted to share my experience in complying with Rotax’ “Time Limit” parts, and their “This time limit must be followed…” statement for the 912iS air-box connecting hoses… Removing the air box appeared to be necessary to replace these hoses. I learned that you CANNOT believe the Rotax Heavy...
