I realize that this may be a stupid question, but I got to ask it anyway.

I am learning to fly 3D and fly the SPA3D and SPA3DT. Originally I installed HS-300's in both planes and have a nasty habit of stripping them out quite easily (watched a fly land on one of the ailerons last weekend and stripped the servo ).

I found out that the HS-300's have been discontinued for over 3 years and were primairily designed for trainers (maybe that's why I have so many of them ). That would account for them stripping out so easily.

My question is, which of the Hitec servo's (keeping cost in mind) would be better suited for these 3D birds? I have a few HS-422's and some HS-425BB's that I recently got. Would these work enough to prevent the flies from stripping the gears out?

Any and all suggestions, advice and/or information will be greatly appreciated.

Thanks,

You may have slightly better results with the 422/425's but they are still a similar material. I would look at the 475's which use the Karbonite gear train which is 4 times stronger. The next step would be the 525MG.

Mike.
