Jet Lag chimmed in before I could. PLEASE BE AWARE the Aggressor II is a lot smaller than the Maverick / Agg III & Ultra Vipers. I have had a few of these over the years. If a turbine conversion is what you seek with an Agg II, I would actually recommend a Wren 44, smaller, less fuel to carry, lighter, and will have MORE than enough power to fly an AggII. If built lightly, we used to bring these planes in in the 10# range.
Good Luck, and I look forward to seeing this one progress.
