I hope to get out to the track sometime this week and give em a go, my usual track shut down but i just found a much better one this last weekend, but they are only open until 7pm during the week which doesn't give me much time to practice. I just broke in the 7 port this week in fact i still have to heat it up with the heat gun to get it turned over, but after 7 tanks i decided to start tuning for power. It didn't take much to get it ripping around the yard
Cool. 7 tanks is not much. You may want to give it another 7 gentle ones just a tad rich before you start tuning for full power. Keep heating it before starting even once it's fully broken in whenever possible. Your motors will love you for it, and last a long time
People often say the 7 Ports have less bottom end, but this is mainly because they don't use a strong enough clutch set up. The 7's like a reasonably late clutch. With too softer springs they will appear to be sluggish down low.
Try the 3 1.1's or 2x 1.1's and 1 x 1.0 if you haven't already. You might be pleasantly surprised.
