Small planes have small wheels.

Small wheels get bogged down in grass, so the shorter the grass, the better. A dirt or paved runway would be beyyer yet.

But, if you are stuck with grass, do the same thing full scale planes do... once you get speed, apply up elevator to get the nosewheel out of the grass, but be ready to decrease the amount of backstick once she breaks ground or it will be a very short flight.

With a 25 size plane, you can also consider a hand launch.

One final word of warning. There IS a club in Farmington. Make sure that you are at least 5 miles away from their field. If you shoot one of them down, it's your fault. If they shoot YOU down, it's still YOUR fault. If one of the members lives down the street from where you're flying and turns on his Tx in his basement and shoots you down, it's YOUR fault. Flying in a town that has a club, but choosing not to join is a lose / lose proposition.
