I have not tested any of the following servos in my RoboPhilo. This is simply a list of similar size servos that might make good replacements.

I did get the 3003 to work as well as a s9203 metal gear.

Replacement servo gears for the SV4032 and SV4140 are now available on the robobrothers website.

so has anyone upgraded the servos yet? if you did which servos did you use and did it make a difference?

[jaybirdtke]

I ordered the SV4140 upgrade servo kit for the hip servos but they have not yet arrived. I'll keep you posted. I hope he will be able to balance on one leg and lift the other leg to a 90 degree position using only the hip servo.

Do the parts also have to come from China, or do robobrothers stock in CA?

[jaybirdtke]

That's a good question. I placed my order a little over a week ago, and have yet to receive even a confirmation that it has shipped.

I received my SV4140 upgrade kit on Friday and just got around to installing them along with the replacement head turn servo. I used the gears from one of the original hip servos to replace the ones in the shoulder that I stripped. While doing so I noticed I had stripped the gears in one of the SV4130 hip servos. So now his only upgrades are the hip servos to SV4140's and it makes a big difference. If you have a RoboPhilo I highly recommend upgrading at least the hip servos. One of the major selling points to this bot is the low cost so I don't think I'll be upgrading many more servos, but only time will tell. Going from the SV4130 to the SV4140 did make a noticable difference.
