ok, so, i ahve the hpi rs4 3 ss old one with a .12. the front diff has the stock spring in it and the read has nothing. ive heard alot of guys lock the rear differential. how with this change the handling of my car better and worse points please. and also i hear you guys do it with blu-tac and it may be just me but ive never heard of that beforewhat is it?

people lock the diffs on 1/8th scale cars as the rear tires are very large and gip much better than a 1/10th scale wheel, they also run front one way diffs making it feel like rear wheel breaking aswell

ahh ok well then is it also common practice to put a spring in the rear to so it unloads the power more evenly off the line?

i have springs in both of my diffs

thanks alot ill try that
