Nope !
Spitfire 1 is a good turner and will surprise many enemy pilots 
As for speed, its a bit slow...
As for gun platform, you will tickle the enemy plane
But with a steady 3-4 sec burst with the right convergence, you might make him go down ! 
What is my "type" may I ask ? 
Ohhh I've seen Spit 1's come after me and I salute them !
I'm often in a Spit9 and win the fights vs Spit1 BUT he was ONE HELL OF A GOOD STICK b'cause he gave me a hard time !!!!
Every time I meet a pilot with Spit1, It can be two things !
1) New player that doesn't know the difference between the planes
2) Darn good stick and he's about to fill me with lead before I finally shoot him down !
Believe me ! I don't drop my guard anymore !! 
Masherbrum what is your GAME ID ?
Phil / OPP7755
You are confident but there are glaring holes in your "basis of reason".
Understand that 2-3 seconds tops and your wing is off. I don't care what you are in Phil, if someone is one your 6 with a Spit 1, you're in trouble. That "slow speed" you were talking about, is now working against you.
Loop? He follows and gets a wonderful shot of your cockpit.
Turn? same as above
Dive? Might be the best, but if they know the Spit 1 and fly it often, you're in for a fight
In game ID is in my Sig - Karaya. I'll be more than happy to go to the DA with you and show you what a Spit 1 is capable of. Your type is what I was talking about. You underestimate the plane you fly against. Even that logic works against you before the fight even begins.
I'm 11-0 HO'ing 110's in a Spit 1. It's about shot placement, just because you have cannon, doesn't mean you have accuracy. Actually, if you see someone in a Spit 1, they aren't new and they'll do what I said in the first post.
Ask Mensa what had started as a staged duel for comedy, turned into a "Serious duel" on our last hop. We were both supposed to be in Spit 1's, he rolled a 262. One pass, he fired first, I lit up his cockpit. Do a search of that thread, the movies might still be good. While it was a joke, that last fight opened a few eyes in that thread as to what the Spit 1 is capable of.
I consider myself "below average" in this game.
