As a new biplane guy that did a lot of reading before buying I think you may like the Ultimate better than the Pitts. The Saito 100 kind of limits your choices to the .40 size DP Ultimate or the Kyosho .40 Pitts in order to get near the performance you want in a quality ARF. Personally I would take the DP over the Kyosho without even thinking about it if you can find one.
