Grass Field = BIG wheels
Well, I thought I did ALL the right things...Found a club, got my Tower Trainer 40 ARF balanced, all radio components worked the right way, batteries charged, field box battery charged, all ready to go! Got to the field, found some nice friendly folks with experience to help me get the engine (Como .40) tuned. Got a Buddy-Box connected, set the plane in the middle of the runway, applied full throttle...and the goofy thing just sat there!!! We had someone give it a little push...still nothing. [>:]
Sure it had rained a bit the previous day, but other planes were leaving the field with little resistance. The tiny 2 1/2 inch wheels that came with the Tower Trainer ARF couldn't even be seen through the grass. I went to the LHS (conveniently located at the end of the field) and got some 3" wheels. Now all I have to do is wait for the weather to break, and hopefuly have a maiden flight this weekend.
Moral of the story...unless you can fly off a paved runway....get the 3" wheels! PS: It also will help keep the prop from "cutting grass" in the wet spring season
