And I highly doubt that you really know, obviously you have competed in an RC Drift championship all year against all sorts of chassis to see how each of them runs to be able to accurately distribute your percentages accordingly, everyone is entitled to their own opinion so I dont mind what you think, I'm jus giving you the opinion of myself and some of the best drifters around the world, when you meet someone with an 03f, have a go with it mate, I think you may want to adjust your percentages accordingly, do you even understand that the 03f has the motor hanging out infront of the front wheels, its totally different to any other chassis, you might work your 05 hard and get say 4 or 5 perfect runs out of 20 but an 03 is so precise you would get say 15 or 16.

Like I said, have a hunt round the net, theres a load of info to be found on how to set your 05, I highly doubt you will find the answer to your question on this forum, no matter how many times you ask, I would suggest 1 deg rear but that again is just my opinion, good luck finding out, PM me if you want to know where to go for your info.
