We are entertaining the idea of bringing these in. MSRP of $500 USD (Valken is a US-based company).

Features (as per Valken):
- Extreme Reliability
- Unparalleled Consistency
- Added Efficiency
- MilSim (Full Auto) Lock Out
- Easy Drop-In Installation
- Quick Change Nozzle
- Ultra Lightweight
- Programmable
As we see it:
The integration of ECU (and controls) into the Engine itself makes fitting one of these into builds a little more simple than the other options.
Valken is a large company, so availability of these should be excellent.
As another option for an external air engine, what do you think?
