Whats wrong with the losi slipper? I run mod, set mine so it lifts the front tires about 3-4 inches and it never gives me issues. However i see people with ae cars having issues and people using them in their 22 with issues. Ill spare everyone on why i think the losi slipper is better.
If you are having a A/E slipper problem in an A/E car then you have way bigger problems. I have never had any slipper problems with my A/E cars, the only reason I switched it on the 22 is because I have so much extra A/E stuff.... Now the real problem I have had is the Diff, I built one with the " really good" TLR diff balls and it felt bad in 6 packs. I was so bummed, I had a local Losi driver do my next diff for me and it lasted 7 packs. So I am running as much A/E diff stuff as possible to see if it makes a difference. I have only put 5 through it now and it still feels great, I am using ceramic balls now to.
