Here is a 14# Stearman flying with a DLE 20.. Looks like plenty of power to me... he took off in a short distance and climbed to a good altitude fast and did a loop. Looks like it is going way faster than scale speed with the 20 to me. I'm glad to see this video because I already have my Dle 20 mounted and a special Jtek muffler thats made for the AeroWorks Cessna 195 to fit the Dle 30 to be retrofitted to fit my Dle 20. The pipes will exit straight down for a nice fit for my set up
Thanks,
