New servos for my 450+plane....please suggest.

I'm going to be servo shopping pretty soon, because my airplane has one servo dead on aileron, and since it takes same size servo as my heli, I'm going to just get a few more to replace in my 450 heli.

What would you guys suggest in micro department? and mini, because my tail servo gets crunchy now...

please advice, thank you. (oh, and yeh, please don't suggest $30 a piece servos, cos I'm looking for something preferably under $115 for micros and under $25 for mini). Thank you

I have a ton of these in my planes and they are in 2 helicopters. There has not been an issue with any of them.

I've been using those in a 450 and they are very quiet and smooth. There is a model TGY 212 DMH that makes a good fast tail servo.

JPF, have you tried the comparably priced Turnigy 306Gs? If so, why do you prefer the 211DMH? I have the 306's all around on three 450s and have been really impressed with their speed, preciseness and repeatable centering. I never tried the 211s and am curious about your suggestion.

The only weak point of the 306s that I've found is that the aluminum main gear teeth will strip fairly easily in a crash. Of course that's not necessarily a bad thing as it saves the rest of the gear train. More fragile servo arms are available to save the main gear but I'm leery of using them.

i'm still here. Trying to decide i kinda want to order all my servos from hobbyking, so that i don't have to pay for shipping twice...

I was thinking of getting a pair of these for my foamie ailerons:

http://www.hobbyking.com/hobbyking/s...arehouse_.html

Notes:
JPF, that servo is backorder and $20
blvdbuzzard, that servo is for 4.8v, I have my bec with 5v minimum, can it still work or will it burn out soon??
holtneil, those are analog and out of stock, I kinda want digital for high precision crashing...
mhills51, that servo me likes, but a bit too fancy for my 450. I need something under $25
crashburn, gearsets only $6, but do they become sloppy from extensive crashing? (i rarely KKKrash, but just asking..)
crasher47.2, i really like that one, but can they handle tail on 450?


i'm still here and deciding.....

just don't put those HXT900's on your heli. they like to strip.

I'm in the same boat regarding servos, the 306/215's are a good, pricey choice. The HK922/933's work fine but develop slop. I got some Emax ES09MA's from Banggood, but they too are getting a little gear play.

be nice to find something in the $8-12 range that held up.

While the 306's are a bit pricey they are well worth the cost. I had quite few crashes due to servo failures before trying them and none since. I had an E-Max cyclic servo fail while hovering one of my 450's and it came right at me. I hit throttle hold and tried to jump out of the way, but still got hit in the back of the leg. Even through jeans and unpowered those blades drew blood. Right then and there I decided that I wouldn't use cheap servos again on anything larger than a 250.

In the long run, considering how many cheap servos I tried, I would have been way ahead money wise if I had bought 306's from the start, but being a cheapskate I had to find out the hard way.

Actually, when HK has a sale they can be bought relatively cheaply. I only paid $18 apiece plus shipping for the last four.

The hxt900s will not work well in a 450 imo. I bet I could kill them with a few hard tic tocs. I've used them in foamy planes and they're ok, but not great for those.

The nice part about the ksy215s/306s servos really is the price of the gear set and how well they perform. I have 400 flights on my 215s and they're smooth and slop free. Last year I pounded in my 450 and it only cost $12 to replace two of the gear sets. Align servos are like $15 per set.
