Yup, but sooner rather than later you are going to have to do that anyway with an electric.

With an electric plane you need a set of batteries to fly with and assuming you have a good fast field charger, another set to charge while you are flying.

That's in a best case, assuming you'll be able to fast charge both packs at once and rest a few minutes between flights.

You could fly with the first packs, land, start charging them ( it will take 1 hour ), screw around talking to everyone for 10-15 minutes, then fly for another 10-15 minutes, wait another 10, then start flying with the second pack.

With electrics you end up with a box full of battery packs sooner or later. Ideally these should be set up to maximize your usage of the batteries.

Often you can combine two battery packs to either get more Amps or Voltage for other planes, or the reverse.

This means you end up with an investment in batteries.

With glows you forgo this investment up front, but end up spending over time on fuel.

The latter is a little easier for the newbie to stomach, especially for decent trainer sized aircraft. Electrics are more convenient though.

In either case you are best off maximizing the use you will get out of your purchase even if it means WAITING now, until you can spend a bit more.

e.g. Why purchase an RTF with a so-so 3-4 channel radio? You can buy a good computer controlled radio now ( or later ) that will handle multiple planes at the same time ( something called "model memory" ).

You'll spend more on the radio, but it will be the only one you'll need for a long time saving you money on each subsequent plane and you'll have a better quality device to use over the entire period of time.

While that may blow your budget, you can buy it now, then wait and get a PNP plane later, etc.

The impulse is to get something you can fly "NOW", but that results in purchasing something less than optimal.

I've been here, and didn't heed the advice, and ended up spending more than I should have over time.
