A small, honor system webezine trying its best to be a laid back virtual watering hole for builders/pilots of Van's RV kitplanes - more and more important in today's increasingly nutzo world.  Brought to you by the Reeves family.

December 15, 2017.   0001Z.  Issue No. 4,459.
  Wednesday evening during the annual property owners meeting at my home field (52F), the property owners voted to restore the name of our airport back to its original 'Aero Valley' (a sectional from 1975).  A 'sea change' event reflecting a new era of awesomeness.  It will take a bit of time to file the paperwork, and the freq. might change, but we're all pretty stoked with the new vibe.
  You can view a PDF version of all (42) slides shown during the meeting HERE.
  Wishing you and yours a happy, safe and RV-filled weekend.

 

RV-6 Getting Some Motor Mount Love at Aero Valley Aviation ...Monk's place

Revised Electrical System ...please review

Only odd spec is the mounting requirement, a 0.125"x16x16 aluminum plate for the full 200 amp rating. Surely the heat sink is needed only for continuous use at high amps?  The heat sink size is the same for all three from 100A through 200A so I would think there is some wiggle room. If I decided to go with an SSC I only have room to mount on a .125 sink slightly larger than the contactor. I'm thinking with typical buss amps there should not be heat issues.

Excellent points! I have revised my diagram to reflect your inputs.
Thank you

 

Problem Solved: Cannot transmit only static ...Stan Bahrns RV-7A

Evidently when I last installed the radio I didn't didn't get the lug on the screw that draws the radio into its mount in the right slot & even though it was tight it didn't draw the radio in far enough.So it evidently made good contact with the pins ok for about 125 hrs & then started losing connection intermittently & finally not at all. Was an easy fix once I figured it out. Probably would have saved a lot of work if I would have just pushed in on the radio in by hand.

Easy Software to Draw Electrical System? ...kaber56

Q: I apologize if this thread is redundant but does anyone know of an easy software program that can be used draw up my electrical system?

A: Visio has an electrical system component in its built in templates.

A: I used MS Visio for my RV-8 (painful). I'm currently using TinyCAD for my Bearhawk.

A: I used Visio to draw my schematic (24 B-sized pages and counting).

However, I was to do it again, I'd use a bona-fide schematic capture program.

There are some great programs out there (Altium, Eagle, OrCad, Pads), which I used at work in the past, but no longer have available, and I didn't want to spring for the three or four figure price tags.

There are some good free ones, though: KiCad, TinyCAD, EasyEDA, and others.

Advantages:
- Does a great job keeping track of all the wiring, including maintaining netlists between all components.
- Easy search of connections by user net name
- Forces you to include all connectors and other misc components
- Generates a bill of materials (often directly exportable to Mouser, Digikey, etc)
- You can build virtual cable bundles by combining individual wires into busses, helping fuselage wiring layout.

Disadvantages:
- Have to learn a new SW tool, and these tools are not easily "self discoverable"
- Have to make individual "components" for all the non-generic stuff like avionics, special relays, fuse holders, etc. This is a big job if you're going glass.
- Are constrained to their grid system and schematic presentation styles (ie, your schematic may look a bit uglier and be more confusing that you'd like)

In the end, though, the benefits outweigh the initial investment to set up the components in the system. It make tweaking and schematic management much easier in the end. YMMV.

A: ExpressSCH is stone simple.

Whatever you choose, congratulations. A thoroughly documented electrical system will significantly add value to your aircraft.

December is the Month to Help Keep VAF Online

It’s December once again, so it’s time for me to beg grovel respectfully ask those folks who haven’t yet sent in their 2017 donation to please send it in now so I can pay the bills I need to pay to stay in business and do the food, shelter and clothing thing.  If you haven’t heard this year-end speech before, VAF is my full time job, my sole source of income for our family (right), and the donations usually determine if we end the year in the black or not.

If you have already donated in 2017, THANK YOU! I’m trying my hardest to provide the RV community with a quality product that motivates, educates and entertains.  I want to keep doing it, but I don't get to make that call.  You do.

Click HERE for all the ‘how to donate’ details, and thank you again to those who help me keep the lights on.

As for the rest of the fam in '17, Susie is still providing free yoga classes to cancer patients (link), Audrey is currently in her 2nd rotation in year one (research) on her path to getting her PhD in Chemical Biology, and Tate is rocking it as a junior in high school - excelling in English, Art and Physics while refining those incredibly important interpersonal skills at the front counter of Freddy's Frozen Custard & Steakburgers.  College soon.

My wife and children never cease to inspire, amaze and humble me with their dedication, compassion and altruism.  My clumsy efforts to continually bring VAF to the RV community is an attempt at bringing a few smiles to some faces in an increasingly caustic world.  My wife and kids set the bar high, and motivate me.

If you choose to donate, thank you for supporting this site with your hard earned money!  I'll continue to try my best to bring you a good product.  Wishing you and yours a happy, safe and RV-filled weekend.

Doug Reeves
Your balding host.
