DIY receiver kits for sale

I have managed to get hold of all the parts to kit a receiver that is approx 2.5 gm I am offering these kits at 30.00 ea. At the moment they are 35mhz I will be looking at 72mhz depending on my success at selling the 35mhz version.

Features:
Auto centering for all makes of tx
single cell batt monitor built on (led on = batt low)
speed controller 1 amp continuous (irlm 2502)
zero current centering for actuators (no buzzing)
100 foot plus range (I have tested it to 300ft tx aerial down)
narrowband no adjacent channel interference
audible setup
audible warning if throttle not low on power up
signal processing so no glitching
failsafe motor off actuators neutral after 1 second of no good signal


If anyone is interested e-mail me on bobsradioreceiver@mmm.co.uk

Well,

I'm interested as well, but do you have any additional details? I like the list of built in features...especially no buzzing and built in battery monitoring capability.

Any pictures or drawings that could be shown that wouldn't jeopardize your project? Is this kit capable of being assembled by an "amateur" solderer? Or is it all surface mount stuff?

What would you get for your 30.00?

some answers

The receiver is fm

I use a very fine soldering iron and the components are surface mount I can supply built receivers for 40.00 but there will probably be a queue so the kit may be the fastest way forward for most people.

It has my own bespoke software so it is not a rip off of someone elses code and I will be able to customise and tweak for special projects.

I will get some piccies on here over the weekend!

These rxs have been flown indoor and out with other transmitters nearby!
I have a Dumas 17" biplane with one in @ 45gm

There is a co2 plane flying outside with one

and several sub 20gm models

Please use the address I have provided to register an interest and I will reply

Do you send to the US?
57$ USD plus shipping is a nice deal for an RFFS equivalent kit. 76$ is also a pretty fair deal on a pre-made RX.
(Unless I've got my pounds and Euros mixed up, these should be pretty accurate figures.)
