The Bottom Line

If you have ever engaged in ACM with an L-39 vs your stock L-29 you know you can out turn it, but the L-39 will out climb and out run you. An experienced L-29 pilot won’t lose to an L-39, but he/she won’t win either.

In contrast, your Viper will out turn, out climb and out run an L-39.  The only corner of the envelope left for the L-39 to hide is in a terminal dive.

Be the first to have the edge...

The National Action Network Detroit chapter says Kid Rock embrace of fake oakleys the Confederate flag, expletive laced criticism of NFL quarterback Colin Kaepernick and unabashed support for Trump have no place in Detroit, where about 80 percent of the city 680,000 residents are black. Kaepernick, who is black, refused to stand during the national anthem while with the San Francisco 49ers last year in protest of police violence and social injustice. "I am resigning from my position with the Miami Dolphins and accept full responsibility for my actions," Foerster said in a statement released Monday. "I want to apologize to the organization and my sole focus is on getting the help that I need with the support of my family and medical professionals." I left for a reason," he said.
