RFW1953, Thanks for the smoke info but I striped the smoke out of my Pitts for weight concerns. I have spent a lot of time trying to figure out what I could have done to add that much weight to the plane. I have to believe the original kit must have been heavy to start with. I'm at 18 lbs and 4 oz dry with the Quadra 52 and electronic Ignition. I have really not made that many mods. Oh well, now I wait for the weather which could be a while here in Minnesota for the maiden flight!

Thanks for the info!
