It's always been my experience with planes in this size that the first surface you see blowback on is the ailerons, so they got the strongest servos. No blowback so far on the rudder or elevator.

It depends on the style of flying, as well. Tyler and I like to do high speed rifle rolls, whereas someone who is flying just 3D would probably be fine with 225's everywhere.

Just what the doctor ordered

Detailed and precise instructions-Just what I needed. Thanks!

The 65MG is just fine on the rudder. Just don't bang it on the ground.

Back to the 85MG on the elevator, you will have to enlarge the servo opening. Before you remove the HS65MG, first mark the fore/aft location of the output shaft on the fuselage with a sharpie. When you cut the opening, make sure the output shaft of the 85MG sits in the same plae, fore/aft wise. Otherwise your pushrods might not be long enough or might be too long.

You will also have to relieve the servo opening a little vertically, so drop the servo downwards. This will allow the use of the big Durbo servo arm without it hitting the bottom of the stab.

I love the speed and feel of those 94809s. They are a great servo but I have melted or stripped every one of those I have had in a 48" EXP. I'm not the only one either. Several of us had the same issues at SEFF this year.

Couldn't imagine a better servo for the Vanquish though!

For 48"s I have been running the HS65s with an 85 or JR 368 on elevator.

I'm going to try some Savox or JR all the way around on the next one.

That's a good point, but these EXP's are very demanding when it comes to servo's. The 85's seem to be whats needed in the back of the 48" planes, but running two in the tail of a MSX will cause a tail heavy plane.

Im looking to try a new rudder servo in the 48's. Maybe Ill try the JR's?

I use the Savox SH-0255MG in my elevator on my 48" Edge and it works great! 54 oz/in of torque, 0.13 sec, digital, and $33.

Tom,

How does the Savox SH-0255MG hold up to the not so perfect harrier landings? IOW, how does the Savox handle 3D abuse?

I've been using them since June and I haven't had a problem. I dragged my Extra's elevator through some tall grass once and ripped the elevator off and the servo survived.

So, Getsome,have you got some more time on your airframe since you last flown it?Sometimes it takes a little getting used to an airframe before it slides into perfection.It took me a few flights to learn what the mxs likes and dislikes as far as my sticks and cg goes.And how my flying style does with the plane.Now I love it.
Just remeber,whatever you change,be it cg,thrust,underwear,whatever,you have to retrim for upright,level flight..I have gotten myself in trouble and in a circle of uh oh by forgetting to retrim for level and upright flight after making a change lol..As far as all the how to's most of them will work,but some may have some cost for another aspect of flying the plane.I have washers behind the motor on my mxs,but the thrust angle was changed a bit by an unexpected nose cone landing when i was new .

Tom,

Thanks for the recommendation on the Savox servo.

Doc and Tom,

Thanks for the help on the 48" Edge. But we don't want to offend or upset anyone on the 60" Extra EXP thread. So, let's take any additional discussion on the 48" Edge EXP to the EXP Owners thread or the 48" Edge EXP thread.

Wisdom from the east says, "What's the best way to treat an enemy? Make him a friend!"

Manta,
Thanks for keeping the 60" Extra EXP thread on track.

So you melted them in the ailerons as well? Did you melt/ strip from just regular use that had nothing to do with hitting the ground (yes I know this is sort of a stupid question )That is disconcerting seeing as I have three of them on my 48"...

I believe Daniel and Donatas stripped a couple in flight at Seff before I got there. Mine just got hot from flight after flight of hard flying at Seff. We were burning pack after pack all day. The reasons we do that at those fly-ins is because 1, we love to fly these planes and 2, we like to find the setups that will hold up to the most abuse so we can share them with customers.

Your servos will be fine if you let them cool off every few packs. those ATX servos are some of the best performers you can put in a 48. Fast, precise and smooth. The downside is that if you are going to work them hard they need to cool off.
