Hi.

I fly a Hobbico Hobbistar 60 MKIII Trainer with a 12x6 prop. The problem with the plane mainly occurs when I'm taxiing. The field I fly at is a little rough and if I hit a little hole the prop goes into the dirt and cuts off the engine in addition to potentially damaging the wood props. And I taxi quite slowly.

It came with 2.75 inch wheels. I'm thinking about buying some oversized wheels (perhaps 6 inch) to help raise the plane off the ground and hopefully make it a little more stable while taxiing. How will this effect the flying? Or is this even a good idea?

Thanks.
