Man I've broken a bunch (at least 6) of lower front arms and a couple of upper arm turnbuckles and only one servo saver part. When I broke the servo saver I thought it was just a fluke. I got rear ended by a MT at the track and it smashed me straight into a wall. I actually run the stiffer saver spring (with a full sized servo) because the softer one was too soft and I was getting bump steer.
What I wish they would do is offer some of the parts by themselves. I'd like to buy just front arms for $6 instead for F & R for $10. Does anyone want to trade 2 front lower arms for 6 rear lower arms? I have 6 rears and need more fronts.
I've also broken a few body mounts. It's a joke to spend $10 for a bunch of other parts just to get the body mounts. And what about the upper arms that are $10 because they come on a parts tree with parts that never break?
Luckily I love the way the E-crt.5 drives both in the backyard and at the track. It's a blast cutting under 1/8 scales on every tight turn.
