I have been flying the Tiffy as my main fighter for the past 9 weeks and love it.
I recomend:
#1. Keep her above 240 mph in the combat zone. I think the Tiffy has better acceleration, or equal, than all but the 109 above 240. Under 200 - 240, most other planes have better acceleration. Acceleration and top speed are your 2 saviors in the Tiffy.
#2. Don't turn beyond 90 degrees with Spits, N1Ks, Zeros and other Angles Fighters.
#3. Never climb to escape. Always run flat or dive to escape.
#4. Go for snapshots. 1 or 2 20mm Hispano hits often result in kills or hindering damage. The Tiffy has the same gun package as the hated F4U1-C, with a little less ammo. I even take 500 yard, 90 degree deflection shots that pay off often enough to make them worthwhile. If you wait for dead 6 200 yard shots, you might wait all day. This is a difficult plane to fly onto a guys 6. When he breaks, shoot.
#5. Keep it under 20K. I spend most of my Tiffy time under 10K.
#6. It's a great buff killer, but not a very good climbing interceptor. Don't go after buffs if they are already significantly higher than you.
