Getting ready to go for the extra. Planning on the EF power combo.
Wanted opinions on a few things-

Servos- are you having good luck with the Hitec 5245 (recommended by EF)? Or are airtronics or Savox digitals better? Don't want to break the bank on this if I can help it!

Arms- DuBro ?

Batteries- I see GensAce 25c 6 cells 3300 on sale. Good,better, best? Flight times with the 3300 packs (60/40 3D/IMAC)?

I was thinking of putting some 3s in series but my largest are only 2200mAh. I assume that's not going to give much time.

Thanks a million for the help. By the time it's all said and done your dropping (investing!) about $700! So I'd feel better having some first hand knowledge (Cody thanks for all your help so far)

Daren,

If you want to be sure that this is the plane for you, you are welcome to give mine a try on Saturday!

As far as servos, I flew mine on 5245's (with a 225 on the rudder) for about 20 or 30 flights before I got my 7245's. They worked great for me, and for most people they work great as well. However, if you are really beating on the airplane some people have had failures of the 225's and 5245's. Chris Jewett has tested just about every mini servo available in this and the other 60" EXP's. The Airtronics 94820's are stronger, center better, and are bulletproof..but they are very slow. Savox are a little weak and you will likely experience blowback when you start flying the plane hard. You can jump to a high voltage servo like the JR 3711, Futaba S9070, or Hitec 7245 but that's another level of expense. IMO a good, reliable budget option is 3 Hitec 5245's for ailerons and rudder and an Airtronics 94820 on the elevator.

Gens Ace 6S 3300's will get you about 6 minutes of medium hard flying...I can wear my 3300's down in 5 and if you are just practicing harriers you might get 6.5 or 7. Gens Ace seem to be the best budget packs you can get right now.

Cody, this reply just exemplifies the reason RC Groups is here. Thank you!
Unless you are immersed in this hobby the choices available can really send you on a Goose chase. Getting good advice from those "in it" that can give honest suggestions with value in mind are going to preserve this hobby.
I like the servo suggestion.
Thanks again.

I have a couple hundred flights on mine and I'm running JR 3421s. The JR HV servos may be the best choice but I'm sure you'll do just fine with other recommended servos.

I personally like Gens Ace 6s 4000mah batteries. I get about 6.5 minutes of really hard flying and still have some voltage to spare. The extra weight is also beneficial with tumbles and keeping the plane from shooting up during harrier and especially high speed roles (If you put in too much elev/rudd the plane will quickly clime in full throttle/high aileron deflection roles, if you didn't know).

Thanks. I made a commitment today and bought 3 GA 6 s 3300s, an Airtronics for the elevator, Hitecs for the rest, Dubro arms and extensions. Maybe some 4000s next. Now I "have" to get the plane! Merry Christmas to me!

You may want to get some aluminum servo arms. The DuBro arms work fine, but they hold the ball-link so far out from the servo that after awhile they develop alot of slop.

Hey michaelJH, do you happen to have a link? I'd like to take a look at the aluminum option.

Since he just went offline, I guess I'll answer.

http://shop.aztechaeromodels.com/Spo...s-AA-SO-TR.htm

These are great servo arms and mine are doing great after 200 or so very hard flights. For the elevator I'm using 1.25" and getting full deflection. On the rudder, I have a 1.25" arm but I'm using the 1" hole because that provides about enough throw to touch the elevator halves. With the ailerons, I was flying with 1.25" arms for awhile, but the amount of throw becomes unbeneficial and really slows the plane down. So I switched to the 1" hole and that seems a lot better. Still more than enough aileron throw.

P.S. They're on sale so now is a good time to get them.

I simple solution is to mount one ball link(or both depending on control surface) on the inside. This assures you have straight bind free linkage(aileron,rudder,one link,servo side in). The elevator has a straight link, I mounted them both on the inside to avoid grabbing bushes..

Ducati, that is the way I did mine. Definately better than on the outside of the arm. Mine still developed slop after awhile though. The DuBro's work fine, I just prefer the aluminum arms.

I heard here on the forums yesterday that the motor was in stock (could have changed) but the ESC was out of stock. The MKII motor is worth the wait, but then you might miss out on the airframe since you probably want the combo deal. I would call or email them and ask questions. Maybe they will let you back order part of it and you can started on the build. The 60" extra even on 15x6 is a must have....on a 15x8 or 16x8 I can only imagine. It is next on my build table.
