The BF-109 share the same flight characteristic as my mini Spifire and of course both came from the same brand and hardware setup onboard. The only difference between them other than the aesthetic looks is the BF-109 slightly slower and less nimble that the Spitty but more docile to control probably because the wings design between them are slightly different. They run on the same 2s 1000mah 30C lipo battery lipo battery pack which makes it economical to fly for everyone. Still its very handfull to handle even for intermediate pilot because its still much twitch on the stick than bigger planes above 1000mm wingspan.
