As a point of reference, my 1979 Tomahawk (125 hp STC) provides 100 kts IAS on 6.7 gph of 100LL. Comfortable; unrivaled visibility.
Although it’s four times as expensive as the Traumahawk (purchase price), you get a brand new bird for your bucks. While I haven’t flown it, to me, this Colt looks like a real winner!
