Sebart Wind s 50e tailplane

I am assembling the model using the Sebart pictures only instruction manual that one of our members kindly hooked me up with.
I have installed the servos, one in each tailplane, and am puzzled as to how to fit the tailplanes to the fuz. There is a carbon rod that goes through the fuz and is then drilled through each tailplane and anchored with a screw each side. My concern is that if I glue each tailplane to the fuz I will not be able to get to either servo should I need to in the future. Am I worrying for no reason?
Thanks

The tailplanes are designed to be removable - do not glue it. You might however want to ensure that the carbon rod is a faily tight fit as any sloppiness results in eventual loosening of the tail planes - this is usually done by smearing cyano or similar onto the carbon rod then smoothing it down with fine glass paper.. I think I beeffed-up the holes where the locating pins slot into too. in my opinion there is 'WAY' too much movent on all the tail surfaces so consider elongated horns on the tailplanes and rudder (and shorter on the servo arms which means widening the slots).

Many thanks John

If you plan to keep the tailplane fitted for storage / transport, another solution which ive used for eliminating any slop is a a smear of clear clear silicone. This allows disassembly if required.

Rudder servo location.
The manual shows fitting the rudder servo in the back of the fuz. However all the hardware to fit a rudder closed loop system is included in the kit so there appears to be a choice. Has anyone experience of the best location for the rudder servo?
Many thanks

Hi Simon, I had great fun with the closed loop system , but life became so much more enjoyable when I put the servo in the tail, so in my humble opinion if you can get the CofG with the servo in the tail go with that.

I also used a Sulivan tail wheel where the steering is done via a spring attached to the rudder, I think this helps soften any shocks that are transmitted from our rough ground to the servo.

I should say that mine is the MythoS, but I think they are so closely related as to not make much difference.

Hi Chris
Ok will go with putting it in the tail, can always counter balance it later and I detest closed loop anyway. Yes I have the Sullivan tail wheel, which spring did you use?
Many thanks
Simon

I used the big spring on the tail wheel.

Are you in a position to put the plane together and hang the servo on the tail to see if it will balance with your battery. I was very nervous that mine would not balance, but in the end I kept (with the help of Jon, but I don't like to talk about that) moving the battery back, in fact I suspect it could still come back a little bit.

By the way, you'll love it.

Not in a position to check c of g yet but I will trust in the wisdom of Jon! And of course, yourself. I used the larger spring for the tail wheel assembly as well.
Looking forward to getting it finished , however I am now trying to manufacture extended horns for rudder and elevator from a sheet of carbon fibre. Not easy! I took JRIs advice and fitted small servo arms to rudder & elevator servos, just horns to do. I'm using X power motor and esc from Probuild, measurements seem to be ok unlike the Savox servos that required a lot of filing and sanding of the models pre cut servo holes to fit.
We will see if it all works out.

As Chris has already mentioned, I would leave your decision about the rudder servo position until you are able to check the cg. You may find with the servo in the tail you will need to put lead in the nose even with the battery as far forward as possible, which you want to avoid.

A direct direct drive linkage is a better option but closed loop works perfectly well. I haven't owned a Wind 50 but have had an Angel S 50 and that had a closed loop rudder.
