Time will tell if the body clip mod will hold up better, I trust NitroPro will sort it out soon and fact remains that NitroPro stands behind their product with a solid warranty unlike AGFrc. So long term cost on NitroPro is nil, but yes... long term cost to maintain AGFrc is astronomical

Regardless, all servos fail over time, typically the gears eventually wear out and having a lifetime warranty on the gears from NitroPro is priceless. The warranty on the SRT servos that I recently bought are only 1 year.... there's always going to be a trade off somewhere.
