I just joined a local club and they have a grass flying field. I guess it gets mowed down to about 1 1/2 to 2 inches. I am thinking about an electric whith 1/3/4 size wheels to start out with, could this work?

I've got .15 and .25 size glow planes with wheels that size. They do fine on grass. Be sure to get light weight wheels. Depending on the electric you are considering, you may decide it's easier to just hand launch.

I fly 40 size glo planes from a very well maintained grass field. The grass is that length (or shorter) and rolled a couple of times a year. I have found that 2" and smaller wheels are fine on a paved surface, but are USUALLY not that good on grass due to the bumps and dips inherent with a grass field. On my Freedom 3D (electric) I use 2 1/2" wheels with no problems at all.

I suggest using 2 1/2" LIGHT WEIGHT FOAM wheels. The added 1/4 oz in weight (compared to regular 1 3/4" wheels) is not enough to be concerned about, but the added diameter will help you quite a bit.

From watching, the guys with the smaller planes have real problems getting off our great looking (from a distance) but rather rough grass field. They have 2 1/4" wheels which is as big as they can go on the small planes without it looking stupid but that barely works. Thats why the smaller planes usually get left at home now. I tried up to 4" wheels on my 40 size and up planes and the was surprized to find that the larger wheels can give you other problems. The magic number seems to be 3" wheels for our field. I hit a gopher hole on the right side on a take off with my Sea Fury. The right wing bounced up a bit and the plane just kept on going! If the wheels was a bit smaller I am sure that it would have went in to the hole and ripped outt of the plane. [X(]

I agree--nothing below 3 iches, at least for me and my field. Right now I have one plane that has wheels smaller than 3 inches (twinstar), and I think they are 2 1/2. The real problem I have with them is prop clearance on grass. On asphalt, it's no problem, but when the wheels sink down into grass, that gives you even less clearance for the prop. I'm fixing to get some 3 1/4's for it.

id go larger... but since its electric it probably wont have the power to loft bigger wheels.... just hand launch it and land it on the grass with skid rails (wire skids bend in 2 places at 90 degrees) insead of wheels...

bigger wheels meen less chance of flipping and shattering a prop :-D
