Just went to the HP site and the price is tempting today...just $230. That is a lot of plane for that price. I have one BH plane, the 60size T-28 Trojan, and in fact just got home from flying it today. I don't know about other BH planes, but the T-28 is a real success story, a very good ARF that flies better than it looks, and it looks real good to start with. Hobby People is good to work with...I got a couple planes from them so far, including the T-28. They replaced a defective canopy immediately with great service. I like bipes and have a CG Ultimate and am assembling a AW Ultimate 50cc. The Pitts S1 is just not as graceful looking as the Ultimate or Python in my opinion, yet it has the kind of look that is classic and attractive like a Sharpe...so ungainly it's cute! (Please don't be offended.) The $230 price on the BH Pitts S1 is pretty awesome for that size of plane. My CG Ultimate is only 54". This Pitts is 59" and has to have a very thick fuselage, which I kinda love. BTW, my CG Ultimate has a OS 120 four stroke on it, and I think that would be too little engine for the BH Pitts. I would guess it needs the Saito 150 or 180 or the DLE 30 like suggested by someone. Hmmm, yes I need another bipe? Jon
