I have a 90 mm high output edf unit for sale. I had it in a freewing f-15, and the jetbwas very fast! Unfortunately, it went down with a loss of signal issue. Edf unit is perfectly fine. Runs on 6 cell battery. Motor is a Leopard, with a 120 opto esc. I don't know that much about this electric stuff, but this setup really made the f-15 scream! Asking 85 shipped.
