You guys, I think I may have to go with the ZDZ 50. I don't know what I was thinking trying to cheat 4 ounces from the motor. I have ZDZ 50's already and have seen them handle a HEAVY GP Patty VERY WELL!!!! I think I'll send this engine back, but it really does look beautiful! Like I said, I might just keep it and stick it in a GP Ultimate, or maybe even the Goldberg 330.
Hotdog,
That’s a great choice. The ZDZ 50 should be adequate for the Lanier YAK. I have a ZDZ 40 on a GP Patty, and it flies a decent IMAC Basic sequence pretty decently. It's hard to make it hover, but will pull vertical fairly well. The new YAK 54 from Wildhare is the perfect plane for that EVO 45. Keep the EVO for another project if you can afford that. The 45 is sure a good looking engine, and very powerful for its weight class. Good luck,
