    high torque on the rudder- the rudder/tail wheel servo linkage ain't easy.

    Hitec just failed my acceptability test after losing two planes in one week because of the failure of Hitec servos.

    I agree with the high torque on the rudder. I thought it looked like it needs it too.

    How did you reinforce the rails with hardwood?

    How did your Hitecs fail? I also lost a plane to Hitec servos.

    What servos were they?

    I had a total of 4 servos fail on two planes.

    3 of them were 311s and one was a 425BB. Two of the 311s were in one plane and the other two were in the other plane.

    The former 2 had intermittent failures were they would suddenly not respond at all, as if they weren't plugged into the receiver. This problem was seen on the same two servos on 3 different JR700 receivers that work fine in other planes with JR equipment.

    The latter two failed because the 425 stripped a gear and the 311 just did not react.

    I also had a 4th 311 fail before a first flight. It was on the throttle and it stuck open and refused to respond.

    As I say, that's the end of my Hitec buying.

    Status: offline     		Hitech digital HS5645MG, std HS645MG and HS625MG, no problems. Flying 30lb warbirds.

    Having worked in a Hobby Shop, I can tell you the lower priced/quality Hitecs can have issues. The 300 series was down right awful when used as a r/c car steering servo.

    With any airplane and servo mfg., I always put in a higher rated servo. This way the servo easily handles the job rather than being a little more or just enough. No different than the chunk of metal under the cowl spinning the fan.

    In additon, keep in mind, every companies servos have failed. I know a guy who lost a BVM saber from a JR8411.

    Status: offline     		The Hitec 311's are $9 servos ( 8$ if you buy 3 or more). Why would anyone not expect something this cheap not to fail? Condemning all Hitecs because these throw aways did what $9 servos do seems a little stern.

    On the other hand, why would a manufacturer produce something so inclined to fail?

    Caveat Emptor?

    I totally agree, how can you not expect problems with a low cost mass produced servo that was probably not designed for the job its used in from the start? I have always bought at least midline servos depending on the speed of the plane and control surface I buy accordingly.
    I guess you get what you pay for but I have to say that my Airtronics 94102's that I converted to BB's with EMS kits really work well in smaller not real heavy planes and the stock 94322 BB is a decent servo for the bucks. As I wrote before I use the right servo matched to the plane, seems to be the key for me

    I have no argument that one would expect to see the 311s fail. In time. But to lose two consecutive planes on maiden flights with brand new servos shows a lack of quality assurance that I expect from a company like Hitec.

    I chose the 311s for these two planes because one of them was my son's trainer and the other was a Seamaster that I was flying off the water for the first time. These servos failed on the planes' maiden flights. That is totally unacceptable.

    My old Sea Master ARF that got broken in a shop accident(the cable guy knocked it off its shelf) had two Hitec HS 605's one on rudder and elevator
    two HS 225 one on each aileron so I could have flaperons but I think I will put HS 525's on each aileron in the new one I never had a problem with the 225's but I can use the in another plane. And an Airtronics 102 on throttle. I had maybe 50+ flights on it before the cable guy killed it. I have a new one in the box in the shop and I will install the same servos in it, its got an OS 61SF ABC that I had recently rebuilt.
    I see your point though.

    Status: offline     		Servos are a vital part of any model. It amazes me that people put the lowest quality servos they can find in a plane. I'm not saying a new comer to the hobby should have all digital servos in a plane, but I think we need to consider the forces on an individual control surface and purchase servos accordingly. I fly helis also, and for the most part, we wouldn't trust our 90 size machines to anything less than full digital servos..........the turning point for me was when a buddy lost a 60 size Mustang due to a failed elevator servo. The servo was a Hitec 425BB. This servo is the standard BB servo included in the flight packs. Probably ok for most light to medium duty applications but the elevator obviously needed more torque. It failed at the bottom of a loop. Lesson learned.

    Status: offline     		Dave, I agree I have lost only one plane to the wrong servo it was a small K&A Models Dago Red electric that I airbrushed in the Dago Red scheme and installed an Astro 020 brushless motor and at the time 2/3 A 500 8 cell pack. Well that puppy came of my pedal launcher and I pulled it up then made the turn crosswind all was good the plane was faster than heck so I went to turn down wind and I had no ailerons( I thought Oh ***** as you can imagine) So I cut the throttle and pulled full down elevator because I didnt want a fly away on my hands. The 020 had a bent prop shaft the plane was totally history even though I cut power I must have hit at 80 mph. The Hs 85 on the elevator was in perfect shape but the Cirrus CS 20 that I installed on the ailerons because I didnt have the room for a second HS 85 had 3 gears stripped I will never know for sure but I really wish I had cut a deeper hole in the wing for another HS 85. Well I got the Astro 020 fixed and took the 8 cell pack to the local HS for disposal.
    Have no fear I had new graphics cut just like the first and I bought more Testors Model Master Enamels and called K&A and bought a new plane. I just need to find time to buildit and I have a Jepe Reno Racer Mustang that I will do as Dago Red I have the graphics for it also.

    So I learned my lesson no cheap servos in fast planes and build the plane to fit the servo so I have all the servo power and strength needed.
    Never again. So I pretty much buy better servos than needed but it makes me feel better.
