Junior - It is still being debated.
I race at least twice a month. Where I race we actually have a Stock, 19 and Mod class. A really good weekend for a mod driver is a race where he brings home all the motors he showed up with. This dosen't always happen. At a State Series race 2 months ago I saw 3 regular guy non sponsored Mod drivers blow winds, unsolder windings from comms etc.
I just got back from a race this Friday and Saturday. Based on the opinions of the guys that sought me out to talk about 4 cell the guys complaining about 4 cell here at at a vast minority. At least 15 guys came up to me at this race and ALL of them Stock, 19T and Mod racers though 4 cell was a great idea.
The winner of the 2006 State series Mod Class was actually talking to all the Mod drivers about running 4 cell in the State Series no matter how ROAR votes. Once again based on the response it look like at least the FSEARA Mod Class will be 4 cell in 2007.
