Hey Guys,

After a long time no doing anything in rocketry. I've decided to sell some old stuff. I'm aware that technology has moved on a lot since I was an active member of this forum (Username: Matt).

I'm keen to sell the following:

  • Walston Retrieval System TRX-3S Receiver + 3 Element Antenna Still selling for $530 USD.
  • Plus a broken CA MODA 2438 MVS-HF The "QUAD" Transmitter (will normally transmit 5 miles, but will only achieve 1 mile due to its broken antenna)

Would be stoked to get $400 USD for the Walston set. However, open to offers :) UPDATE: Offers for the Walston have been around 200-250 USD, so Accepting anything above this!

Other stuff I have is.

old school Minialt/WD perfectflite altimeter + minitimer3G which I'm happy to throw in for free with the Walston.

I also have 2x Xtend 900 RSPA Transcievers if you want to do some fancy stuff. I haven't used them beyond testing they work.
Would be happy to sell for $250 for both. (Will only Ship to US, Canada, UK, Australian and New Zealand Addresses for these). you can see the product in the link below.

I also have a 68ci carbon fibre grey ghost Ninja high pressure air bottle + fully adjustable mega regulator. I was using this for some cold gas experiments. paid $290 USD for it. stoked to get $160 USD. will include the SCUBA filling adapter and everything to fill easily. SOLD

I also havd some great solenoid valves for directing cold gas. Worth around 400 USD. Happy to add in for 200 USD. SOLD

If someone wants to give me an offer for all of these will be happy to give a good deal. $700 USD for all of it.

As these items are based outside of the USA. I'm happy to cover shipping costs so nothing blows out on anyone.

Cheers guys!
Mat
