LOL ,yea it could but it is not my intention. Garbage is probably a harsh term. For that I apologize. I am meaning entry level ie 325, 425, 475 that quickly become one of those things that collect dust. (And as my other half puts it, if it collects dust garbage it...lol) They are good for 40 size and circuit flying 60 size. Once the flier has progressed past this they become unused. People will say to use them on the throttle but I found that after a year or 2 I was looking for a very fast servo for the throttle for more response. Definitely buy in your price range but try to keep the next plane in mind when buying to avoid wasting money. As you progress the aircraft becomes more expensive. It also depends on how long you want to fly a particular plane. It took me about 7 planes before I found my nitch (extras and ultimates, mainly extras, no other plane does a lomkavek as beautiful as a scale extra 300 and no other plane flat spins better than an ultimate)

I don’t know about the 6635. I tried a 635 once for a pull-pull and found that even tho it was ball bearing and good torque and speed the tension put on it by the pull-pull caused the centering to become terrible. 635 is not an entry level servo either... One of those servos that I completely dislike and sits in its box un-used… I wasted $30 on it… Good thing I only bought one!

To each his own. Some people will like some servos other people will hate those same servos.

Keep in mind that servos do wear out. Their motors die, circuit boards fail so don’t buy with too many planes in mind. I usually buy with the next size of aircraft in mind. With a 40 size I get something that can stand up in a 60 size and with a 60 size I get something that can standup in a 120 size etc… That way I can replace the gear set and get another season out of them and I can trust that they are less likely to fail from stress. You will reach an impasse tho. When you become a more aggressive flier servos will wear out faster. I am usually pretty hard on mine. Full power blenders and fully power crazy water falls. My buddy (who is the video below) is counting how many more blenders I have with my reactor before he thinks my servos will fail. (and probably will) Seriously the blender spins so fast and so hard the whole maneuver including the flat spin is a blur.

I have a friend who flies 44% imac/pattern and he changes his servos out completely every season. Talk about expensive at $200 a servo across 13 high voltage jr servos. But when your plane is worth $15,000 it is minor compared to a complete loss.

Here is a video if any one wants to see him fly. The vidographer cut out all of the rolling loops unfortunately. The rolling loops are text book great, even the bottom of them. Too bad they were cut out. Including a rolling loop that consisted of 1 roll for the whole loop. I have personally watched him do harrier rolls 20 feet off the deck with this plane and 10 feet off the deck with his 35%. Lol, I could feel the wind from the spinning wing tips on my face! The plane below is a one of a kind Extra 330, very few were made. Hand crafted no less!! All composite.

For cheaper servos and 60 size planes I usually use 625, 645, 5625. I consider these cheap. Keep in mind that I am hard on my planes hence the reason for the stronger servo. With my recent 60 size ultimate and having tried 985, the 985 is my personal choice but it is expensive.
