Hitec servos are great. Only had 1 fail a hs82. You want junk overpriced servos that flop around center get some JR.
I may try some mks eventually but they are pricey. Not cheaper than name brand so I'll stick with what I've been using for 15 years.

Im replacing my stab servos in my older UF I have 2 of the JR DS8411, what do you guys recommend?

Thx!!

Dave Wilshere

Hitec servos might not fail, but 100% the are the least accurate servo made, they don’t centre. I’ve test flown models and without being told what the servos are, said to the owner to junk the Hitec servos…how did you know they were Hitec.
You will never trim your UF with Hitec servos.
JR Propo made the best servos ever, so Sir you clearly don’t know what you are talking about…

and yet you recommend mks to me

just typical jet douche brand loyalty. Heard the same crap about kingtech 12 years ago when I was flying them.

Jr servos are trendy, not good. Then went bankrupt.

I have jl viper 1.9m with hitech for 12 years. It flies great.

I don’t use MKS, but what I use is not available in the US. You asked for a recommendation, but since you seem to be a Hitec expert crack on and continue being disappointed.

Depending on the age of the kit the servo pockets in the stab might be a bit tight for most of the “standard” full size servos available today. The 8411’s are a bit thinner. Later kits have a little more room. I’d consider the MKS HV747 (mid size) or MKS HV1200 (full size) if you have room. The 747’s will require a bit of adaption to the mounts but this is easy to do. If you need lower voltage servos look at the MKS DS1220.

If it was mine another option for the older UF Would be the MKS 747R would much easier to adapt to the panels…..

There is no perfect Servo.

I will say tho, I completely agree with DW, Hitec is crap, I won’t run them either. For all the same reasons he said.

JR has always made good servos but they had some gear train and case top issues on some models in the past. The new servos do seem tempting however. I have never had a JR Servo fail out of hundreds owned. But when they went bankrupt I switched to Jeti and won’t be going back as far as transmitters and receivers. I would be willing to try some servos tho.

The latest trend is to but jets as pnp and all the brands seem to have different no name servos. Carf, bvm, pilot, global ask do that now. End of servo wars?

Which a lot of are rebranded Savox.

I've built a C-ARF Ultra Flash and had it seriously damaged due to a servo failure (I won't get involved with the above "servo wars" so let's just leave it unnamed). I was interested in getting a replacement Flash (3-4 years ago) and was initially excited to hear about the Flash Evo but the more I learned about it, the less enchanted that I became. Please correct me if I'm wrong, but it looks to me that all C-ARF did with the Evo is to make the main tank bigger (at least that saves having to attach a wing tank, losing the inlet ducts, and making the plane slower.

To me, creating the Evo was the big opportunity to correct the major issue with the Flash which was the one-piece wing. C-ARF could have used the opportunity to make plug in wings rather than us all having to drag a surfboard around. Since my wing needs repair, maybe I'll just "splash" the wing shape and use it to make a three-piece wing with a center section containing the gear, smoke tank, and flaps, and plug-in outer wings and ailerons. This way I can transport the plane on its gear and plug in the outer wings when it is time to fly.

What do you guys think?

Jim

It's not made of fiberglass anymore is a foam now. Way lighter and much weaker.

Id fix yours.

LOL, ok.

What are you talking about? I have the newest UF Evo and the wing is composite - glass & carbon and there appears a layer of Rohacell foam sandwiched in the wing.

I've seen Evo's go above 200mph w/ 180's.

Ive been using HiTec servos for over 20 yrs with out issues
5955's 7955's D955's in jets - Flash classic , U-flash , U-lightning , F-5
7980's 7990's in 43% carden's
Never an issue to date , plus I like the programmability
As for never being able to trim a UF with Hitec's ......thats BS rite there mate !!

Its not fiberglass, its a foam composite. Much weaker but lighter. Im not a fan of it at all due to the rash.

My Feedback: (1)

It is a composite made of a foam kernel and fiberglass / carbon on both sides. This is the same material that CARF has always been using and a typical way to build composite aircraft including full scale.

Really, there is nothing to worry about. This is state of the art stuff.

My Feedback: (11)

There is a very light layer of fiberglass on the seams is all I see. But my point is that is not a epoxy resin/fiberglass layup. Not saying its not safe, it just much weaker than glass in terms of rash resistance. Its like handling a foamy you have to be careful.

My old JL 1.9m viper is heavy glass and rock solid bullet proof more my style!

dude I put up with this when kingtech was new and now all these brand boys fly them.

I've given in before and bought jr and had issues. I gave in again and bought some mks for this jet and I fear I didn't learn my lesson the first time.

I really hope this jet is still fast my rebel pro is too slow.

Sorry typos my phone is junk

A business is gunna push any product that they can make the most profit from and which manufacturer pays the most - its all flavour of the month
I fly quality electronic products that have a good rep & back their product -

I fly pretty much only and installed lots of MKS….they are pricey but solid……not sponsor, not a rep I pay full price for my stuff just like any normal dude….and I had quite a few JR MP series servo’s that were junk and lost one F3A plane because of them….I do have the JR3911 (3) in one jet hopefully that wasn’t a mistake, wanted to try them…spec wise they look good.
