i hear ya, the easiest motor to tune and forget it is the mach 427 lst2, the hardest and the most challenging is the genesis and the nemesis engines the 76. if you want frustration go with that one
, then let off some of the frustration with 5000 lipo in a sc10 and have some fun for 20 min , then go back to starting and get blisters trying to start that beast. those 2 trucks took 3 gallons each of nitro and are finally running good , but before that all i wanted to do was throw them across the yard
