Digital servos on a t-rex?

       Remove this ad - become a site supporter!
A heli buddy showed me a web page at ashtek electronics of a mod putting the digital board from an hds 877 into a hs-65, then someone on helifreak started a thread with that link. In talking with Rob and the more I think about it, I wonder if putting digital servos for the cyclic on my t-rex SE would be something worth doing. The only unmodded digital servo that seems like it would fit is the hds 877, but apparently it can have problems burning out. Modding the hs-65 into a digital one seems like a good idea, but would the addition of digital over the normal functions of the 65 be absolutely unnoticable? Thanks. One person on helifreak said they use digital for cyclic on their rexy, anybody here use digital mini servos for collective on a rex? (or mx I guess, close enough too)

I was using hs55's for a while. Now I run HS56's. They are pretty good. I throw the Trex around pretty hard, and crash it pretty often.

So, digital servos are not for me. The rex flies great on 56's, maybe a little smoother on 65's.

So I really don't see the need to waste your time changing them over to digital. Better to get out and fly.

I have to second the vote for the Hitec HS56s (or the newer HS65s). I think your money would be better spent on power systems (and metal upgrades to support them, if you don't already have them). If you want more performance out of the HS56/HS65, run 'em at 6V using a separate BEC.

he will be flying a SE and all the metal parts he needs
The digitals wold give better centering and more torque would they not?
I have tought about trying the digital out as well. I already have the hs 65s and love them.
What do you mean , I can land upside down

Hey - it's only money. If you have unlimited funds and the specs are better, then go for it. If not, consider power system upgrades and running the servos at 6V. Personally, I don't think it's worth bothering with.

If price is no object why not use Futaba 9650's all the way around? The specs look impressive

The little SE is not precise enough in design to really benifit from digitals. The best servo right now on the market for the swash is the Hitec 65, for the tail it is the Futaba 9650. I have tried em all, seriously.
Once upon a time there were Nitros, Flybars & Frequency pins
