Reviews (7)
Includes 7 reviews aggregated from around the web.
There are very few reviews for this servo on the web. One buyer running two for steering on a 1/5-scale truck rates it 4 out of 5, calling it very fast and strong and a great upgrade. A second-hand unit that did not respond at all was reported in one forum question, but it was never established that the servo itself was at fault.
