The reliability of electric flight systems can't be understated when the model is hovering this far from the ground! In part 1 we hopefully de-mystified a little about motor and propeller selection, aircraft types, and speed controllers, so lets tackle that other old chestnut - batteries, and finish off with a bit about radio gear. First off I think I should expand a little more on how I select a battery for a particular model, because as they say there is more than one way to skin a cat and this applies to getting our required wattage too! I like to try and keep the Amp draw down to around 45A maximum and the best way to do this is by increasing the cell count. EG: if we want say 800 Watts, then on a 3s Lipo ( approx 10. 5V ) and a given motor and prop combination, that would require a whopping 76A.

This is a two-part beginner's guide to electric flight basics - hopefully in a simple to understand form. It is not a complete A-Z of everything you need to know, but should help to de-mystify some of it, so put the kettle on, get the sticky buns out and come over to the dark side. . .

Well the day finally dawned for our Great Orme sloping fly-in, and despite the previous week’s weather of flat clam balmy summer-like days, the forecasters thankfully got it right on the day. The suggested meeting place( ASDA cae )was approved, and with gloves, boots, wooly hats and freshly charged gear, I arrived at the rendezvous to stock up on sticky buns. As I was ordering the bacon buttie, a tap on the shoulder heralded the arrival of Des(Whittaker) Owen, good friend and budding R/C flyer, who had agreed to do the photo-shoot for us with his posh camera. Next to arrive was Lee Morgan and his Carmel club mate and fellow forumite Richard Bond.

An Orca 3s 11. 1v 2600mAh Transmitter Li-Po battery Using Li-Po's to power your receiver and transmitter? Why would you want to do this? Ok, let me start by looking at some advantages - Li-Po’s are always ready for use, they have hardly any self-discharge, unlike NiMH cells. They’re lighter than equivalent capacity NiMH cells (usually an advantage in aeromodelling). They wont drop voltage to the level that the airborne radio may stop working.
