In Northern Kentucky, where I wasbeforeVirginia. it wasn't uncommon for the ground to turn white in mid-November, we'd not see dirt again until the following April. Bah.

K&B "Screaming 48?" just check the reviews. Normal airplane version is rated for peak power at 15K rpm, other versions over 25K rpm with a pipe.

The type 4800 is rated 2.0 hp at 15k, the 4825 DF engine goes up to 3 hp.
Even subtracting hype it has to be a really strong engine. The 8702 at 2.1 hp, 7510 at 2.5 hp, and the 8703 at 2.7 hp. And then the 7525 - 3.2 hp at 25K rpm.

Power or not, running at 25K rpm it's going to be screaming.

Bill.
