I got a sig mayhem 1.20 with a dle 20. its a power house.  dle 30 on a 1.20 giant ultrastick.  it hovers easily.  10 min flight is 4-6 oz fuel.  got a da 50 on a 50 cc size 330.  I go to the flying field at least once a week.  I have a one gallon can.   I run all three on 32.-1 mix.  I fill my gas can about once every 2 months.    4 bucks worth of gas and oil mix for 2 months worth of  Wind Therapy.   It doesn't get much better than that.       That's why I no longer fly nitro.  Gap your dle 30  ngk cm6 plug at .024  after break in if u still have mid range burbling that you cant adjust out.  </p>
