Swapping CGA320 valve over to CGA326, and installing high flow siphon...

Procedures? Is a new hydro test required after doing the swap? Looking at getting a B35 cylinder but what I've been finding are all set up with CGA320 (CO2) rather than CGA326 (N2O).

I've found B20 set up for nitrous but it's not quite a big enough tank for the somewhat larger EX motors I'm considering in the future. A B20 will handle my baby M but probably not a large M and not an N. I don't want to deal with transporting a B50. Too heavy. Unless I get into EX hybrid O motors in which case there is no choice but to go big. A B35 would get me through this year and next and still be manageable. That's why I'm looking for that size.

Thanks,
Gerald

We are busy and innovating. A certified N motor not an ex motor is being tested before TMT certification.
Hollow cone injectors with 2 gallons per second of NOS flow are being machined not jut for testing but for addition to our website. Lower cost NOS valves for L1 L2 motors. The .375 orfice CFF 1/2 NPT Solenoid valve. This Continuous duty solenoid valve uses only 11 watts of power.
There are no problems it is just that you have not yet found the solution. When you hit that problem reach out.

Dumb question, but anyone know of a source for stainless braided jacket PTFE lines with brass 4AN fittings (or 4AN on one end and perhaps NPT on the other) rather than the colorful anodized aluminum fittings? I don't trust aluminum fittings for repeated installs and removals.

Thanks,

I've been wanting to get into hybrids for a long time, but was always put off by the cost of GSE. Then, the other day, I found a 10lb NOS bottle in town for 160 canuck bucks.

"It's an older bottle, sir, but it checks out."

When you get it hydro tested, have them put in a siphon tube, most likely it doesnt have one. You can use the Nitrous in it if it doesnt you just need to hold the tank upside down.

Although I only made one Hypertek J flight in 2022, I love the challenge. I did my Level one and Level two flying an Aurora with a Hypertek J. That was a long time ago before the rules changed. I flew my Level 3 on a Hypertek M. Nothing beats an almost 10 second Hybrid M burn.

My goal this year is to build a launch trailer that will easily support both Hybrid and AP flights. I plan to minimize the hybrid setup as much as possible, but still make AP flights easy. We have a basic design and I have found a vendor to build the trailer. I have two M projects, one repair of 6" project and a 5" project. I plan to fly the 5" on the last MFX Grain I have with the large 5478cc Tank. (M1040). I'm shooting for 20K feet if I can keep the weight down. All of my 54mm up to 4" are designed to fly on either Hypertek or AP.

I highly recommend the challenge!

For those interested, I have a bunch of Hypertek documentation.

Are the lower cost valves on your site yet? How much?
