Durable and slow are often mutually exclusive. You need a trainer. I don't know of any which will fit that engine (oops motor). Your post will likely be moved to the electrics forum within a day or so.

Personally, I think foamies are good practice, but you need to learn how to fly first. I have seen some traditional trainers which are e-powered, but the motors for those are HUGE and so are the lipo packs.....and the price too.

In this forum, you will likely hear a lot of people telling you the same thing...'get a high-wing glow-trainer and an instructor and learn to fly safely'. I think it's the best advice you will get, but if you are set on electrics, go to the electrics forums and ask around there.

I know there are some small electric trainers and they will fly slow; but durable?...no. Durable and light, (i.e. slow), is not very common.

I think you should learn to fly 4-channels. You will get more from this hobby if you start right and learn the basics well.

Good luck and welcome to the end of free time and disposable income as you know them.
