Cheap electronics are always hit and miss, you definitely want to test them within the first 30 days and generally any problems should be honored by the distributor, if they give you any grief, then usually PayPal will offer buyer protection.

I would caution that Solar servos do best on HV, however it's very important to properly set your end points... if you put too much stress on the servo where it binds past what is mechanically possible in the steering throw, then you can burn up any servo in seconds

If you decide to go with name brand servos, be sure they offer a true service center and have the ability to repair servos after your warranty has expired. There are many brands which offer warranty, but don't have true service centers which kind of defeat the purpose of the higher expense in the first place.

My strategy has been to rely on budget servos with backups of a budget servo where I have an instant replacement if something goes wrong... any high end servo could force you to miss 1 or more race days waiting for service.

I stopped trusting Solar servos many years ago and have migrated to PowerHD (also rebranded through Turnigy) and recently have been having really good luck with the brushless servos from JX.

Another emerging budget brand that I'm hearing good things about is SRT:
