Title: E5
Post by: joe28 on November 13, 2015, 09:28:54 PM: Been out of the hobby for awhile.

Last heli was an N5.

Looking at building an E5.

Is the E5 being discontinued?

Thanks

What configuration are you going for? 556, 606, 626? 6s/12s?

I am just a sport flyer nothing big
Still thinking about setups

Thanks

Post by: joe28 on November 16, 2015, 08:20:26 AM: What servos would be good to use?

I am just a sport flyer and don't need to break the bank for servos.

Are TORQ servos good?

Thanks for any advice.

Post by: Rodney Kirstine on November 16, 2015, 11:31:12 AM: I have only used a Torq tail servo. I believe that if you use Torq cyclic servos, you will need to add shims to them so the cases don't hit each other.

You might want to take a look at BK servos.

Post by: Danny Dugger on November 16, 2015, 12:15:20 PM: Torq servos are good, I have a set on my N7 that I've run in a couple air frames for 3 years. Been through multiple crashes and still going strong. All you need is 4 extra "servo hold-downs" to put behind the mount tabs on your left and right cyclics. http://mattbotos.com/store/index.php?main_page=product_info&cPath=0&products_id=1171
Ugh tapatalk keeps breaking the link. But it's part number 106-115 in the Synergy store.
Same goes for MKS.
Easy peasy.

Post by: Cliff Chmiel on November 16, 2015, 12:39:20 PM: im running bk servo on cyclic there great and mks tail servo 7.4 volt, on my e5s and e7es.

Post by: Grees01 on November 16, 2015, 12:40:47 PM: Hey Danny, do all MKS servos needs the shims to work in the E5? I was looking at getting a set for mine? Good to know if I am going to need shims. (With regard to BK servos, I have them in my Goblin 570 and they are working just fine, no issues so far?) I know nothing about the torq servos however, never had any.

Post by: cml001 on November 16, 2015, 01:55:57 PM: I don't know if there is a difference between the E5 & E7SE... But I have MKS 960 cyclics on my E7SE.. It didn't require shims.. That i know of.. Flys fine..

I would recommend buying the shims, all the MKS servos I've used have just barely touched at the center of the frame. Torq have very similar case dimensions to MKS.

Post by: Grees01 on November 17, 2015, 10:35:13 PM: Thanks guys. Is 106-115 the correct part number (servo hold down) at Amain?

Yes sir.
Title: Re: E5
Post by: Grees01 on November 18, 2015, 11:23:24 AM: Thank you very kindly..... Still undecided on servos, I can get a nice set of the MKS 960 - 990 on the promo for 527.00 and deal with possible spacing issues, possible servo horn screw interference ect ect, or I could get BK servos which are better specs according to the information listed and smaller, on promo for a set for about the same cost, and shouldn't have spacing issues? I don't see that Futaba makes the servos that Matt listed in the manual any longer, not sure what the replacement for those are? Never seen a package deal on Futaba servo's either. Hmmmmm......
Title: Re: E5
Post by: Danny Dugger on November 18, 2015, 12:14:21 PM: As far as Futaba S9352HV or S9353HV (exact same as the 52 but w/ aluminum case) are probably the way to go. You pay a huge premium for an aluminum case from Futaba :( That's the only thing that annoys me. They're really awesome servos though.
Title: Re: E5
Post by: Robert "Full" Montee on November 22, 2015, 07:18:27 PM: • Futaba BLS272SV (Cyclic)
• Futaba BLS276SV (Rudder)

These are the servos I run on my Synergy helis and other 700 class helis in the past.
Title: Re: E5
Post by: Grees01 on November 22, 2015, 10:02:22 PM: Thanks Danny and Rob for the replies. Danny looking at the S9352HV that is a cyclic servo recommendation correct? Seems like it given the specs? If so then what is the matching Futaba tail servo recommendation?
Title: Re: E5
Post by: Danny Dugger on November 23, 2015, 07:28:02 PM: Yes those would be for cyclic. The BLS276SV that Montee mentioned would be my choice for the tail.
Title: Re: E5
Post by: Grees01 on November 23, 2015, 09:31:43 PM: That's pretty expensive for 4 servos 650.00 plus tax and shipping, too bad Futaba doesn't offer some type of package deal on a set. OK, I'm still thinking about it. Thanks for the info guys.
Title: Re: E5
Post by: Danny Dugger on November 24, 2015, 12:29:27 PM: Certainly nothing cheap about Futaba, but they're top quality. If you buy through Tower Hobbies they have some good coupon codes (see attached)
Title: Re: E5
Post by: garettoku on November 24, 2015, 11:45:42 PM: I use the BLS272 cyclic and BLS274 tail servo. Have them on my E7SE and N7.

I just noticed that these servos are categorized as car/truck servos... not sure what that means from a programming standpoint. The specs look great, but I'd probably go with the BLS272 or BLS275 to be safe. They're proud of those 275s. $$$
Title: Re: E5
Post by: Mike Spano on December 02, 2015, 04:08:39 PM: I have used a set of car/truck OMG servos before. they worked flawlessly with the vbar. but I cannot speak for those futaba ones, but I do bet they would be ok.
Title: Re: E5
Post by: gwright on December 03, 2015, 12:58:02 PM: primary difference is deadband. Ever notice in years past, futaba had servos as "92" and "91" with the "92" versions being classified for helis,..i.e. 9155/9255. The difference was deadband. Same with the car servos. I'm actually using servos that are called "car" servos now,..but far less expensive than most would think are OK. both my E5S (600 on 6S) and E5SS (715 on 12s) are using Futaba 3470SV's on the swash, using 8V output from BEC. Torque and speed are fine, they're sbus2 so if I actually wanted to change deadband or anything else they're capable, and at $45 ea from tower, I could just keep spares around if I wanted to. They're 3/4 ounce lighter than common "heli" servos also. If more torque was needed (which it isn't), the 9470 could be another choice, but they're $100 ea. I do work at Hobbico, the Futaba importer, but I pay for equipment also, it's not free,.. and I think these are the best value. Matt flew my machines at triple tree in september and loved the setups.

Support guys tell me that deadband is the primary difference. On planes you must have much wider deadband or the surfaces will sit on the ground and flutter. Helis and cars need far less. Unfortunately there isn't a super inexpensive superfast servo in the lineup, so standard heli tail servo must be used for the tail to work well.

Usual caveats apply,.. Futaba doesn't call these "heli" servos, and you use them on a heli at your own risk,.. but my experience is positive.

Post by: Grees01 on December 03, 2015, 11:44:57 PM: Hey guys, thanks for the replies. Sorry I haven't been active on the forum for most of the last week. Been busy at work, and busy working on the Synergy at home after work. I went with the BK servos on a Black Friday special. Paid about a 110.00 each. The Synergy is back together and close to done, still waiting for Alan Butler to get some canopies on stock, and waiting for a shipment to come in from Ralph at FBL Rotors, that particular shipment for whatever reason is taking a long time to arrive. I bought the titanium link set, the ball link pliers, and the swash plate tool. I will finish up the setup when those arrive. Hope all is well with everyone. :D
