K1 Servo saver

[AdrianJones]

After running at Telford the other week it struck me that the K1 has no built in servo saver (stripped the B2 gear).

I am running a JR DS845 servo which at the time cost me loads and was and still is a fast strong top quality servo. However their is a sacrificial B2 gear inside which I stripped. I have run this servo in my 1/10th touring car, B4, SC10 and NEVER had an issue until I run it in the K1 where it stripped the B2 gear. This was when I realised the K1 does not have a built in servo saver.

Can anyone recommend an good servo saver which will it?
