hey guys. With so much advancement in the technology for heli's i was just wondering what would be a good servo to get for the hbk2. A guy like me who's new to flying would never be able to pick a decent servo without some good input. what do you guys think would be good to get?

Very good fast servo. You will find re packaged version of those all over. Just buy about 8 of them if they break just replace.

The place in Hong Kong so it can take some time to get here.

The two best servos for the HBK2 are the Hitec HS-55 and Futaba s3114. The 3114 is a fast and quality servo but the mounting tabs kinda suck. The HS-55 has better mounting but is a little cheaper made. Both run $14 each at a hobby shop. If you are running the stock radio, then you have to have a servo that moves the same direction as the stock servos. I know the s3114 moves backwards to the ESkys but not sure about the HS-55.

The Hitec HS-55's do rotate in the opposite direction as the stock Esky 8 gram servos.

I bought the hs 55's for the King and they do well.
I broke a couple of the mounting tabs on them because I always seem to need that one last turn.

Anyways I got some of the black cases to replace them and they are alot better. Haven't craked one yet

Happy flyin all

They way I'm currently thinking about servos is; don't buy them for your current heli, buy them for your next heli. If you get some nice servos for the HBK2, then continue upgrading the gyro and tail servos, stepping up to 450 becomes that much easier. If you total the HBK2 you can move the electronics over to a 450 kit. Assuming they survived. With metal gears survival rates are pretty good.

Not that I would recommend this path, but I'm currently running the DS185s with metal gears at 6v. They came with the DX7 kit and I had them laying around collecting dust. They are digital and a little slower than the recommended speed for cyclic (.18 at 4.8v). But at 6v they are plenty fast for the HBK2 (.14ms). The plastic gears strip easily and all 3 of them strippped in my last crash. I upgraded them to the metal gears. Plus the tabs are a little fat so mounting them on the HBK2 was a little tricky.

Let me counter Gregs idea. Lets say you own a King2 and know you want to move up to a 450 in the near future. So you are buying new servos and are thinking of following Gregs advice of getting servos that will move up with you. Well first off the likely best servos for any 450 are HS65MGs. Sure these are great servos but they cost $36 each, are a bit of a tight fit in the king and also kinda heavy, 11.2g vs 7.8g for a s3114. That may not seem like much but after you add 3 of them, you have just added on 11g onto your tiny heli. On top of that, you could almost buy all three s3114 servos for the cost of one HS65MG.

In closing, sometimes it is just better to buy the right thing for now rather than try to buy the right thing for later use.

Gotta put my two cents in...

There is nothing wrong with the stock esky servos other than they will strip a gear when you crash. I did say when. If anyone ever says they havent crashed while learning I will call them a liar to their face, even if I have to drive there. You are going to crash, but that will only help you in learning how to rebuild your heli which will in turn teach you more about how your heli operates.

If you are just starting, stick stock, they are cheap at jags and replacement gears are even cheaper. Buy five or six servos and the same amount of replacement gears. That way if it is catastrophic, pull off the three cyclics and replace them with your spares and fix the broken ones on a rainy day.

Once you progress and are spending more time flying than fixing, and starting to ff, THEN look to other servos. By that time you will have more experience and will have read more on here about this fact.
But if you are hell bent on putting something new on your heli (been there, done that) then disregard everything Ihave just said and go with Chris.

I for one totally agree with Triple B, you don't have to upgrade the servo's to fly the King. A heli can turn into a MoneyPit REAL QUICK

Of course it's your right to do if you wish but its not really needed. Keep flying, stick time, stick time and you will crash less and less, upgrade when your skills get better. I never flew the King with anything BUT stock servo's. Just my 2 paso's

I'm starting to see a pattern here

Anyway, here's the rebutal.

11 grams total increase on a 500 gram heli is really not that much. Really. I dropped 20 grams just changing motors. If 11 grams will make or break an HBK2's performance, you'll have to stick with plastic frame, stock landing gear and stock canopy. Maybe if you are running the brushed motor, it'd be a problem. But not for most every HBK2 out there, 11 grams is minor. Unless the heli is already a little on the porky side.

My point about buying for your next heli is mostly based on the fact that many original HBK2 owners have long since abandonned thier HBK2's in favor of a 450 or other heli. There a few diehards left but the majority of HBK2 owners move on fairly quickly.

To Tripple B's point (and Dougs' aggrement) that makes perfect sense to me. If you aren't investing in your next heli you might as well not dump a bunch money in heli that will he shelved well before the servos are ready to be retired.

Well Greggor,

While I have added a couple of 450's to my fleet, i still fly the king. Matter of fact, I am working on a completely stock king with only BL motor, direct servo to swash linkages, and purple tail with a 2100 gyro. Those changes I consider to be of utmost neccessity.

My other king is blinged out except for all CF stuff, and TJIN's 3114 servos, he got me hooked on those.

I found that when I put the direct linkages from the servos to swash, the stock esky's work really well and are very responsive. It is just the stipped gears when you crash. But I keep at least 10 gear sets on hand.

And for the record, I have tried esky, hs-55, hs-56 w/carbonite gears,hs-65MG's, JR 185's, and 3114's.

As of this posting:

Stock king stock esky servos
Blinged king 3114's
MiniT hs-56's
MiniT #2 hs-55's
Trex 450SE hs-65MG

the 185's were almost impossibly small, even for the king. But I still will keep them for some upcoming project( he he he)

For me, I went through a lot of different type of servo's I think Hobby City ones are best one. They're alot better then stock servo's for 1/4 the price. There is No reason to get expensive servo if you're just learning, you're going to crash hard and end up damageing $12-$30 servo. Far as I know Servo are dumb electronic, they don't have thing in there that will improve your flying.

If you're just learning just use cheap stuff that work. I got like a dozen of them, if you want I can ship to you for same price as Hobby City.
