New to electric flight?

Don’t know where to start?

Want some simple answers?

Then this section is for you.

By now you have some general ideas about what you want to fly.  We are going to assume that you’re looking at a fixed wing model, and don’t want something too big, aggressive or expensive to start with. 

We’ve picked a handful of models that will be close to the sort of aircraft you want to fly.  So look at the size and type of plane we’ve described and find one that matches your project or is close to it.  You can then use our data to select what you need without having to understand the engineering behind the information.  That can come later.

If anything our sample aircraft are over-specified so there is some tolerance in your selection but they will put you in the right ball-park.

Use the key information that we’ve identified to make your own decision on brand and source.

There are four steps to follow;

  • find one of our models that is a close match to what you want,
  • look at the equipment list to see how its been set up
  • Take note of the key characteristics and develop your buying guide
  • Select a vendor’s products are a good match to the key parameters.

Out of the Box – 2M Glider

Radian by ParkZone (now out of date) - EFlite now only produce a Night Radian - most fliers strip out the lights to make it lighter!
