I posted this question in the Warbirds forum a few days ago, and got no replies. Maybe my luck will improve here *COUGH* Bill Robison *COUGH*. Anywho, I'll be working on the Bridi Tigercat this winter, and was wondering what guys have ran for engines in this bird. I've looked at the Mgnum 52, but am afraid that won't be enough for my altitude of 3500 feet. The Magnum 70 looks good, but it weighs 5 oz more than the 52, for a total of 10 or more ounces for both engines. I've also looked at Saitos, but they give no weight specs on these engines on the Horizon site. Their are definetly more options with Saito, the 56, 65, and 72. Prop clearance will not be an issue, as this plane could clear an 18 inch prop no problem according to the plans.

So what is your opinion everybody? How about some retract advice as well. Thanks friends!
