E-Flite Ultimate EP Build/Modifications


I called this thread the E-Flite Ultimate EP Build/Modifications since I don't want to do a whole build thread since it is not a complicated plane. But there seems to be alot of mods being done. Soooo, I may pull some of them together here.

Feel free to post your ideas/pictures/comments (like everyone doesn't do whatever they please here anyway.)

Oh, and I am posting this in the parkflyers forum--and not the foam/3d/aeroabatic forum--since I plan on little heavier and tougher build. I want it for pattern aerobatics, and G.Hicks has said many times it has to be light for 3d. BTW you can chat with him at RCuniv in his forum. I will incorperate several of his suggestions as well.

The pic to the right is the stock ad photo. We'll see how close I come.

Sand smooth the edges.


This is sometimes hard with depron. It gives a nice finished look, and improves the arerodynamics.

Landing gear mod.


I saw this one elsewhere. Using the supplied thread is just too tedious for me. A zip tie and pieces of wood. The LG seem very wimpy.

Next time: a big one--How to mount the tail servos. Hmmmm...
Dec 22, 2004, 05:30 PM

Tail servos


Easy way, cut holes and mount them like a shockflyer. Not so easy way, mount like suggested and find some really long servo arms.

Will fly for food
ON my Tribute, I had to do long servo arms for the tail servos to get the throw required. I used a couple of standard Futaba arms. I cut all the arms off of one of the micro small X armed arms. I pressed this into the Futaba hub and used soem thin, then some medium CA to attach. This gave me a longer arm that fits micro servos.

I am surprised that some manufacturer isn't offereing some longer micro servo arms. I would buy a BUNCH.

Servo mounting and wing reinforcing Mod


I am surprised too that they didn't include long servo arms. I put them through as suggested.

I also used wedges of foam to stiffen up the wing surfaces.

Here is the stabilizer support.

Aileron servos Mod


Manuel says on lower wing . Hicks says on top wing. Top wing mounting should make it easier to get my Vertical CG correct.

reasoning: if you mount the battery up high and need more weight above the thrustline it may be hard to move some of the other radio gear.

Aileron connection rods Modification


The instructions are WRONG in my opinion. Turning around a control horn fixes the problem. What is the problem you ask. The e-flite way the upper and lower ailerons do not move the same amount.

Battery hold-down mod


I designed this holder so I could easily adjust the battery position for and aft, and so the battery would come loose during a crash and not ruin the plane.

I consists of a velcro strap and a rubber base. The rubber base is sticky so that the battery does not move unless a violent tug--crash. The rubber is actually tape. See pic.

Landing gear mod #2


The gear is way too wimpy. It spreads apart just sitting there. This mod consists of a piece of wire held on with thread and CA. This holds the rubber bands in the right spot.

This next one is detailing, not really a mod.


Adhesive checker board.

Great thread, I've been thinking about moving my servos from the bottom wing to the top as well and moving them closer to the ailerons.

I agree, I had to swap my control horns around a few times to get them to work right.

It's a great flying bird, love the way it just floats around in a harrier.

BTW, the checkers are cool, did you use a sharpie or is that checker board trim tape?
