[NSRCA-discussion] Tech-Aero Designs open for business!

Along these lines....

Part of the point of the system config I run is that both RX lipos and Vregs are identical so it is much simpler to maintain backups and compatability.

Part of what I do to evaluate the health of the system, is on odd # flights, I plug in lipo #1 and Vreg#1 first and lipo#2 and Vreg#2 first on even # flights.  In this way, I know each system is working every other flight.  At pretty much any point in time, I can check the voltage of the individual lipos, and if they are not very close to the same, I know one lipo is getting weak, or one is doing more than 50% of the work in the air.

With the TP480s, the all up weight is about 68 grams - less than 2.5 oz, and easily good for 10 flights.

Hi Lance:
There are other products coming that will have capabilities like that, only much more. This is really designed for Pattern type apps, to keep the weight way down.  BTW, it's easy to run two or more FlexRegs off just one switch.  I can offer that packaging option to save cost and eliminate another hole in the side of the cabin.  For the Electric power guys, it can also be used without any switch at all.  That's what Dave Lockhart and some others are doing.  His configuration winds up being only 0.8 oz for two FlexRegs, plus the weight of the two batteries.  I think he's using a pair of TP 2C 480 mAh packs.  I use pairs of TP 2C 730s.  Very light.

Thanks again for your suggestions.

Ed

Ed,
Thanks.  Here's a suggestion for the future.  Put an LED onthe reg that lights when the power is flowing.  You can put an RC on the front end so it won't light unless current flows for more than 1 sec or so.  This way you can know if the backup battery is kicked in.

A Tech-Tips page has been added, with Tech-Tip # 0106 - Redundant Power Configurations in PDF format.  Thanks to Lance for the suggestion.  I had also received some private inquiries along the same lines.  We'll be adding more tips soon.

Thanks!
Ed

Congratulations, Ed,

Welcome to the world of hobbyist gone wacko by starting a business.  Like the "redneck" jokes:
You may be an AeroSlave if - you start a pattern business based on your hobby time interests.

Here's a tech question for you.  Can you provide a schematic for how one uses this new product properly for battery backup, etc.?  I published an article in the KF last year on how to wire two packs for redundancy and it did require a regulator on one pack.  Is this similar or do you have a better/different setup.  It's hard to evaluate the advantages of your product without seeing the applications diagrammed out.

I'm pleased to announce that Tech-Aero Designs is now open for business. The initial product offerings are based on the Failsafe Programmable Regulator design that I originally designed to resolve a product feature gap that both Dave Lockhart and I were struggling with about this time last year.  We both wanted a very precise, small, light weight, ultra reliable regulator system that would work equally well with any battery technology.  Besides being able to function with ordinary single battery systems, it also had to be more precisely settable than any other unit available, in order to be an effective, balanced solution for redundant battery configurations.

Between Dave, myself and a few other local Pattern flyers, we've accumulated a full season worth of flawless flying with the pre-production units.  Now the Tech-Aero FlexReg is available in production.  Please visit us at:

Thanks!
