I realize that there are other forums for radios and servos, but think maybe this belongs here as it relates to servos as recommended for ARF’s. I have always used the so-called standard Futaba servos, the S148, S3003 and S3004. I just fly the 40-46 and 60 two cycle powered aircraft, and have never even questioned whether the servos were o.k. Have used them in 60 powered planes such as the Goldberg Tiger, and 46 powered planes such as the GP Revolution and the TH Kaos. I noticed recently that more powerful servos were mentioned in the forum in discussing the Revolution, and then saw an advertisement for the Revolution that I think said a minimum of 54 oz-in was required. Also am interested in the Skylark 70, and a review indicated a minimum of 54 oz-in. Wow! This is why I avoided bigger planes, so I could use the standard servos, and knock on wood, have not had any failures (that I know of) from inadequate servos. Some of my friends assure me that the standard servos are fine (I don’t do any 3D) but am nervous going against either a manufacturer’s or reviewer’s recommendation. Any thoughts or information or ideas greatly appreciated.
