RE: Reaction 54 Jet Kit
How did you decide on the PST 600R as opposed to a JetCat 60 or 70? The JetCat is a bit more expensive but is more common in the US. I think the JetCat has a speed limiter (pitot tube with feedback to the ECU) which the AMA is trying to encourage. The PST is a good engine, but I don't think the ECU has a speed limiter feedback option.
I am very interested in your modifications to make a larger tank capacity as the 50 ounce seems a bit low with the 7-9 ounce per minute fuel consumption engines.
What are you doing about redundant power supplies? Power augmentation for the digital servos?
