Default I need advise on servo horn please

I just put a JR Z8800T high torque digital servo in my 1/8 scale hydroplane and need a heavy-duty servo horn but am not sure what to get. Any suggestions?

Thanks, Danny

I think Dubro makes high torque servo arms that are readily available in most hobby shops. They make three or four types for different manufacturer's servos so just pick thr one you need. Just so you know, it comes on a runner of 8 or 10 horns so you will have a few different ones to choose from

I'd go with the Du-Bro's. A little over a month ago I learned an interesting lesson from trying to trick up my radio box. I bought some of those sweet looking anodized aluminum servo arms that come with 3 plastic adapters for whatever servo you're going to put it on. Went to a race and had nothing but steering problems. Trying to sort it out I thought that the servo was semi-toasted so I swapped it out for a new one. Same problem. Got home then started tinkering with it as the LHS guy said that those plastic adapters are also considered servo savers. Yup, checked it and the splines were stripped!

This is what I go with,

the super strength, they won't break and you can have them for JR and Futaba, airtronics.
Have not broken one of them yet.

I also tried those alum anodized ones for my jr 650 servo, and it didnt even fit the horn ... [sm=confused.gif] Tried several brands at the lhs and no luck ... Had to settle for the ones that came with it ...

I just bought a JR/Spektrum servo as the LHS had only that heavy enough for what I wanted, that's when I noticed the very large size of the splined output shaft. The ofna aluminum arm wouldn't fir it at all as none of the adapters fit not did the arm without using them.

I've learned the hard way, went back to the factory supplied arms. Why? Better to break the servo horns then strip out the gears.. Kinda want the weak link to the easiest / cheapest to fix and repair. Do note that 99.9 % of my boats are tunnels.. Performing flips at speed looks neat and all, but it's a hard impact on everything with the motor hanging out the backside.

I agree, different boats have different requirements. In my case, scale style hydros are more likely to bend a rudder or kick it back than damage a rudder servo

Sorry for the delay but I have been busy. The Du-Bro horns have been ordered and installed. Now I just need it to stop raining long enough so I can try them out.

Thanks everyone for the advise!
