Thanks, Andrew.  I appreciate the compliment.
Yes, that is an OS Surpass .70 in the nose. Had it in an old Sig Hog Bipe, and figured with a beefy 3 blade prop on its nose, and a little throttle management, it'd sound pretty tough on the little plane, and fly it close to scale. As it turns out, with a master airscrew 12x6 3-blade on there, it's dead-on scale. Does fantastic verticals, hangs at the top, but doesn't act ridiculously over-powered at all. After it hangs there for a few seconds, it starts sliding back ever so gently...just like Jim's.
The wheel pants are off an old Seagull Razzle I played with for a while, before planting it into a tree. They're a bit long, so I chopped about an inch off the back, re-glassed the back end, and they came out very nice I thought.
While I'm typing madly away, I'll mention that I took the Bulldog out to the field this afternoon and got a couple of flights in. Since Sunday's maiden, I've increased the down-right thrust to the very precise measurement of "4 washers", which helped quite a bit. Verticals are...well..vertical now. Also fixed up a couple of areas where strength/workmanship had been lacking (new wing-bolt plate, that sort of thing).
Must say...like the real one, she's a handfull in the air, but a real joy to fly. Jim once described the actual Bulldog as "an absolute blast to fly, so long as you enjoy arguments." I'd say this little model captures that sentiment quite well. It's capable of any trick you can throw at it, to be sure. It sure does demand that you fly it though. One note of caution to anyone thinking of building one...it lands like what it is...a short coupled high wing loaded biplane. In other words...a brick. Keep the power on, though, and you can grease her right in.
One last bit of commentary, directed at Andrew. Your plans are exceptionally well done. While I found the "instructions" and article you'd written on building the Bulldog handy, I'm certain it could be built straight off the master plans. More importantly, they result in a solid, touogh little airplane that's not the least bit heavy. So, kudos to you, sir.
Along those same lines, thanks also for TilePrint. A REALLY handy utility, not just for printing out these plans. I'll definitely find use for it on future projects, to be sure.
