I just had to have it! Iflytailies.com gave me (ok, I paid for it, he didn't really GIVE it to me) this airspeed indicator for my DRI. It took an afternoon of work to get it put together. And another hour to figure out how to mount it. But I think it turned out really nice. It is miles ahead of anything I could build. One more step in the "When is it done?" scale airplane building.
