Absolutely. Can't wait!

It does seem rather unnecessary. It seemed obvious even with a cursory examination.

It all works great, stop your whingeing and get it built.

Worth the trouble - then some.

I wouldn't worry too much about the fus ballast - flies just fine on the wing.

Where does the flap horn go? The fuselage is in the way.

Fuse ballast....

questions - if anyone knows the answers it would help.

Are you supposed to be able to put both bars in the fuselage at the same time?
Why does the longer bar have two screw holes in it? on mine there is no way to get both bars in over the CG at the same time.

Surely better fuselage ballast would haven been higher flat plates like the wing ballast into a ballast tube, rather than square bars screwed to the fuselage side.

I can't imagine how I am going to get the v-tail pushrods past the end of the long ballast bar. I might not bother with the fuse ballast, although I aggrieved at having paid for it when it seems a choice between either having pushrods to the vtail or ballast? Guess you have to go with the pushrods.

The longer bar does have two mounting screw holes on it, one is to use at the middle of the bar, for when you use the long bar only. The other is offset to use when you tape the two bars together. Tape the bars so the end closest the nose is even with both bars, then use the hole that is closer to the nose. This will keep your CG centered.

I doubt that you will ever need both fuse ballast bars with the wing ballast that you have. I tape my ballast bars to a hemostat to jig it around to meet up with the fuselage side hole. It's fiddly and not fun to do at the slope, but it works. When the screw is tightened down on the ballast bar, I pull the hemostat off the tape and am good to go after that. Both bars do fit in the fuselage, if you mount everything as per the instruction sheet, but it is tight!!

I don't think I will bother with the shorter bar then.

How did you get your v tail pushrods past the long bar?

Go back a few pages for a copy of the instructions.

I have you V tail pushrods....


They are only 3mm dia.

See my pics earlier for flap horn position, it did take a couple of attempts, and a slight kink in the push rod due to the rear wing fixing nut being in the way - I did file it down as well.

I'm aware of the servo position mike. The model is very.similar to the old prodij which I had.

The problem I foresee is that the long ballast bar extends WAY down the fuse (and even further if you use both bars). Even if the v tail servos are right up against the fuse I can't see how they would run past the ballast.

I think I will mount the flap servo at 45 degrees like a t-tail servo. I can't see another way to get sensible geometry.

Although I see no reason why it has been made so difficult. Control surfaces are pretty fundamental to an rc model, I would have thought.

It all works if you use the suggested servos, and 3mm rod. No binding, the servos that run the v tail rods are at staggered hights so they run parallel to the vertical line of the fuse, not the horizontal line (across), so there is no width issue involved. The output arms are about right on the bottom centerline of the fuselage, and the ballast stays off to the left hand side of the fuselage.

The ballast seems to go past the centre line of the fuse to be honest.

My point is with the servo and horns, the pushrods are past the centre line. But so is the ballast in the opposite direction.

I will have to try it and see.

Skim down the servo mounting plate.

With everything fixed and glued solidy onto the servo plate I then ran its backside on the belt sander. Oh Ah!

By the time I had finished the servo casings (top and bottom) were right against the fuselage sides, the plate was no more than a lolly stick. After all it has no value other than where the screw fixings are.
I wrapped it all (servos / wiring etc) with insulation tape to add strength and tidy up the wires then screwed it to the side.

You also only need the shortest servo arms you can get.

Look at the flap servo movements required before making decisions on horns etc here. It does want a fair amount of up throw in snap.

Unfourtunately not Mike.
Since April some personal and family related charges and restrictions keep me 100% off from building and 95% off from flying .
Perhaps this becomes better in Q1/2013...

R, Tom
