Servos? Futaba 3010 vs Hitec 635 vs HS645?
hey folks.. looking for some opinions on servos from some of you who have used these various servos.. I'm going to put together a Seagull .60 sized Edge 540 this winter and I'm looking into the servos that I'll need. I'll probably use 6.0 volts regardless of which servo's I choose..A few folks have been using Futaba 3010's on this model (high torque plastic gears), but a friend of mine says that the Hitec 635/645's are a much more precise servo.. Anyone notice the Futaba 3010's to be more 'sloppy' than the hitec? Also, will the hitec karbonite geared servos be sufficient for a .60 sized 3D airplane? Planning on using a Saito 125 for power..
Thanks for any input!

Yes, the Futabas are *much* sloppier than the Hitecs.
I bought some 3010s for my Mojo60 and was really disappointed how much slop I ended up with on my control surfaces, despite using ball-joints on all linkages.
I ended up taking the 3010s out and putting Hitec 5925s in for a *huge* improvement.
Watch out using the HS635s for 3D however -- they have karbonite gears which wear really well but will shatter under sudden shock loads.
You *might* get away with it on a 60-sized bird but personally I wouldn't take the risk -- I'd go for metal-geared servos. The small increase in price would seem inconsequential if a stripped karbonte gear resulted in a loss of your model.
From the Hitec line I'd say that the HS625 (if you're on a budget) or the HS5625 if you want digital would do but you'd really find that the coreless hi-speed metal geared digitals (whatever the equivalent of the 5925 is these days) would be the bee's knees.
However, since you can also get the HS5955TG for around $90 a pop, consider carefully before spending more than $55 on any other digital servos these days. the 5955TG is just a killer servo and for the sake of $10-$20 I'd consider it a *much* better buy than any other coreless digital on the market. They are *fast*, *strong* and the gears last forever. If you buy a 5955TG today, you can use it in your 40% gaser tomorrow!

XJet,
thanks for the response, and for validating what I thought about the futaba 3010's.. I'll probably opt for the HS625's as this project does have a budget! Seems like they should last for quite a long time..
