Who buys servos from tower??

http://www.heliproz.com and http://www.ronlund.com both have them for 69 for the 9252s

9451 is metal gear, its my experience that metal geared servos get sloppy with the vibration from a heli, I'd stick with 9252s

i guess because i used tower to compare the prices between them, im saying you have to buy through them.
http://www.heliproz.com and http://www.ronlund.com both have them for 69 for the 9252s
saying 2 other sites sell them for the same price reaffirms what im saying.

im not going to go into metal vs plastic geared servos, but its my opinion that servos arent forever and if your eventually going to replace them anyways, go for something with a little more performance.

also re: metal gear, i believe the best most powerful servos there are, are the 94758s by airtronics, and theyre metal geared.

i have 9252s on one of my sceadus, 9402s on another which are metal geared coreless not digital, and they seem to be pretty good servos. in a sceadu that i have thats in the process of being built im going to use 9255s which are metal gear digitals. then on yet another im thinking of the airt 758s.

they will all work, and work mmmGOOD, rest is just in the details.

The measurement systems used by Futaba differ from those used by Airtronics/Sanywa/ACE.

When comparing the catalogue specs of the 9451 to the ACE 1111 or AT 94758, it appears the AT and ACE sure do have an edge.

If you put the servos on the same measurement system, they are all very close.

Many of us are now running the 9451's because it is a rated 6 Volt servo.

The first gear of the 9451 is a nylon gear - and it is the same gear used in the 9252 or 9151. In a crash, this will be the gear that fails, and therefore, the replacement gear set is 'normal' because you use the 9252 or 9151 nylon replacement gear set.

The 9255 and 9451 are new servos, using new metal gears. They have proven themselves that wear is not the 'typical' we've been accustomed to with metal gear servos of the past.

I've been running them on regulated 6 Volts in my Tempest for over 14 gallons. There has been no sign of unusual wear or excessive slop developing. They have equivalent slop to the 9252's, with more performance.

I ran the ACE servos in my Raptor 50 for about a month. I then put the 9451's in and noticed an improvement. The 9451 is also lighter than the ACE anchors.

Here's a brief list of who else is running these gears that I know of.

Marcus Kim in his Raptor 90.
Eric Larson in his Fury.
Matt Botos in his Fury.
Bobby Watts in his Fury.
Jason Krause in his Raptor 50.

CCPM is really sensitive to a sloppy servo, and we are all running them with no issues. For an mCCPM machine - there is not even a question that the 9451 is an outstanding 6Volt rated performer. Now they've proven themselves in the eCCPM application as well.

I'm not sure where the "metal geared servo's develop slop" comes from, I've heard that alot, however I've been running metal geared servo's on my heli's for over a year, and they are rock solid and stable as the day I bought them, and that was used. I fly them hard 3d on a regular basis, and so far they are holding up great.

Jerry said it all.

I ran the 9451's on my Extreme for about 5 gallons and they were awesome. I could definately see an improvement over the 9252's.

I just got 3 brand new servos from Dino at East Coast Extreme Helis, and after setting up my Stratus, all of my ATV's on all 3 CCPM servos are at 100/100. They are perfect. There is hardly and backlash in these servos, and after many flights the mesh still remains tight.

I am running these servos on 6 volts, and they are crazzzzzy. I am using a Duralite 6v regulator with the Duralite tail step down diode. They are extremely fast, crisp, and return to center every time.

I would go with the 9451's if I were you.

Well Mr. Wattybotts. Nonone asked you for your .02!! I would go with the futaba 9003s and run them at 7.4 volts. I dont know how long they would last but they would kick ars for awhile!!!

For real though. I think either way you go youll be fine. Im running the 9252s and I dont have any problems. I know Bobby was running them before and there werent any problems. But I probably will be switching to the 9451s in a bit.

Do the 9451's draw a lot more current than the 9252's? If it does, then I'd say stick with 9252's, you won't notice a difference between 9252 and 9451 on a mechanical CCPM set up.
