After filming some RC aircraft I've often thought that it would be fun to add some special effects (SFX)...so I had a go. Considering the small amount of time invested I think it came out OK. What do you think?

I think a bit more than OK 

Tell me, isit true that many scenes in Battle of Britain were shot using RC Aircraft?

I don't actually know Sanjay. It is a very old film so I doubt they were radio controlled. But I could be wrong.

Well, yes actually. From Wikipedia:

The other need was for models in aerial sequences, and art director and model maker John Siddall was asked by the producer to create and head a team specifically for this because of his contacts in the modelling community. [Note 4] A test flight was arranged at Lasham Airfield in the UK and a model was flown down the runway close behind a large American estate car with a cameraman in the rear.[citation needed] This test proved successful, leading to many radio-controlled models being constructed in the band rehearsal room at Pinewood Studios. Over a period of two years, a total of 82 Spitfires, Hurricanes, Messerschmitts and He 111s were built.[21]Radio-controlled Heinkel He 111 models were flown to depict bombers being destroyed over the English Channel. When reviewing the footage of the first crash, the producers noticed a trailing-wire antenna; this was explained by an added cutaway in which the control wires of a Heinkel are seen shot loose.[22]

Wow. That's very cool. Good to know. Thanks ! I'm not far from Lasham.

Awesome video
