Try bigger wheels... and shorter grass. Not sure what you mean when you say you're "looking for something different" ..? A smoother surface will certainly help... but if a prop strikes that, it will break much quicker pn hard surface then on grass.. I guarantee that. Is it the take-offs that are the prob, or the landings?... Take-offs you have to run the motor up, so the prop is spinning fast of course, whereas landings are usually just glided in... and shouldn't be a problem. I'm betting these are thinner props being on a small electric plane.

When you say it struggles though... It sounds like you're trying to fly it off a surface that is just too much for the plane... The rougher the surface, the larger the plane needs to be...or other measures are needed.. which I'm sure is why you posted the thread..

If you have a local hobby shop, maybe they can offer suggestions, or have different props to suggest too. You asked if there were any issues you should be aware of... which is why I replied with a bit of info on the amperage draw vs. a larger/different prop... Unfortunately too... props are, and can be a part of the learning curve... and some people buy a half dozen at a time, and eventually learn too. The Apprentice series really is a decent set-up to learn with. Good luck with it
