For years we flew planes with retracts on grass fields. They don't mix well. For the most part the retracts were very weak and fragile so it wasn't a good idea to be taxiing with them. At our field we never taxi for takeoff either. Someone always places the plane out on the field for takeoff. This helps to make sure the engine is cleared out and warmed up properly. With fixed gear things are due for a change. I'm really glad that this thread was started because now that you bring it up it does seem silly. The only thing missing now will be the loss of exercise from not having to run after everyones plane. Mike
