With you on that one.
Did hear about electric brakes but the Electron and Lado web sites make no mention, we (GBRJET) on the other hand do produce an electric brake option for our Stinger gear set, and as we have designed an electronic module to drive gear AND brakes we can custom make electric brakes for most gear systems.

Its the way to go.

Good work!
That is true, they said they were doing them, but I have never seen them!
I did however, look and play with the GZ brakes at Jet Power 11!
Very impressive, but you can never get a response when trying to contact them!
How large can you go on yours? Would like to see details!

Retract doors, retract locks, air up and air down.  Means the spring idea wont work.  Also doesnt adress the brake leaks.

Here are the Electron specs (models up to 88lbs)

Come on, you gotta consider this, it’s less agro than air!

I'm definately going to check into them for now but given one of my  jets already came with the gear its hard to give them up.

It sounds like the best way to go is a fail safe.  It just sucks there is not a fail safe for brakes.  It just seems to be a simple idea to have an onbaord c02 to get thing running in an emergency.

JT potentially as big as you like, certainly anything the jet market has around....

Is t here a thread on those where I can see they are tried and true?

Pablo was testing some electric retracts and I think a new electric brake system on a BVM saber. So some new products are on the way.

RAM engines use pressure off of the compressor to monitor the engine out put but it is only around 20 psi and its not that hot being that its connected to the ECU via plastic tubing.

Parts needed in a nutshell, minus a few ancillary items I am sure:

Arduino Nano (or mini if I want to save more weight)
http://www.gravitech.us/arna30wiatp.html

Pressure Transducer (certainly can finder cheaper than this)
http://www.omega.com/pptst/PX40.html

C02 Pressure regulator (one of these, would have to look deeper at each one)
http://www.genuineinnovations.com/cu...hnologies.html

Then of course a check valve, and air valve, a servo, some line and that would do it. A small C program for arduino and it could be put together for what looks like perhaps $100-$150. Probably not worth it but would be a cool project.

Basically arduino connected to pressure regulator and and air valve (like a on/off brake valve). It monitors the pressure with the transducer. The gear and brake channel from the RX connect to the arduino and it monitors the channels. If a command is given and the pressure is below the limit, it will kick in the c02 by releasing the valve and the c02 will then actuate the doors, gears, brakes and will "fill" the air tanks with c02. Once pressure is back up is closes the valve.

The arduino nano has several PWM channels that can be both read and written to. So it can read RC signals from an RX and can controll servos, escs, electric valves etc.

Might be cool next season as a winter project. This season I am using an arduino to make a fancy gear/door sequencer. Might post about that somewhere.
