the billet servo saver is available, i got mine frome Kamikaze Toys and Hobbies.nitrohouse is also a good place however its only the idler side and the lower on the servo side.The upper right side still uses the plastic kit part witch kind of makes it a fancy $125 waist.However the guys who run OFNA have been testing at the track were i run and i broke one wile they were watching me run and they took the part and said they were sending it back to china for a redesign .So we will see?
