Yes, thanks for the pics. When I was talking to Mike, he said they would be looking into strengthening the tail surfaces. I wonder if they have come up with anything.
I haven`t put my new one together yet either (probably cause it`s flying weather not building weather LOL)
We talked about the tail wires as well but I like the nice clean look without them.
My buddy offered to put carbon spars in the horizontal stab for me. That sounds like a good idea, super strong and nice and clean.

Brilliant kit bash idea

I've been agonizing over what airplane to get to polish my aerobatic skills. Short story is,...... I woke up this morning with a brilliant idea. I have two Sig models that I simply love,.. both severely bashed, an TL25, and LT40, see my web page link below. I love bashing kits, especially ARFs. I really wanted something "more exciting" I just about jumped on a Sig Something Extra, but instead, I just bought a Sig 4 Star 54. Here's my grandiose idea...... and other plans for this model.

1. I will raise the wing on the fuselage about 1" (guessing right now) until I see the plans or 3-views. That's the biggy. >> Does it come with plans? I'd be willing to bet it does not.<< It will give the model a MUCH better look. I'm not a real fan of low winged models. My modification will greatly improve the looks of the model, in my opinion. First thing that comes to mind - "You are going to ruin the airflow over the stab.". No.... not that high. I think ~1" will totally change the looks of the model while still allow great flying abilities. I often go by "TLAR". I will maintain the same wing incidence of course. Other mods will be,....
2. Stripping off all coverings
3. Add turbulators to the wing LE.
4. Examine and strengthen the stab. structure, maybe just tail support wires due to failure reports.
5. Replace tail wheel assay,... I don't like the tiller bar arrangement even though I'm sure it works good.
6. I will add a spinner,.. gees the model pis I've seen just beg for a spinner.
7. Moving the wing up will allow me to give better support to the landing gear mount structure whether it needs it or not.

Yes, it will be a lot of work. And I'm probably a little crazy, but I love to build, it's my hobby. The advantage of an ARF to me is a guick basic build that I can improve upon,.. not to mention going over the model to inspect glue joints and covering it in the colors >I< want.

That's it,..... so far.

The model is ordered, so I will be starting a discussion thread immediately, which will change to a Bash Thread when I start it. I will post a link here.

Sorry to disagree, but no, it is not like a Something Extra. I considered that model at one time. For one thing look at the airfoils, another look at the tail moments and ws/chord, relationship, two totally different models. And you must have missed the point where I related that I enjoy bashing Kits or ARFs into what >I< like. It's what I like to do.

I seriously looked at the Something Extra, but I could see myself crashing it very easily. The 4Stars look s a little tamer.

I have both a sig something extra and a the star the both fly great but your right the longer moment arm and the airfoil make it an easier flyer. I fell symmetrical airfoil makes for a better flyer in all conditions inverted and upright it also provides better tracking.

Hi, is your 4 Star 64 still flying good with those tail braces. I have not had a chance to build my new one.

Amostafa, the Something Extra is going to be my next step in aerobatics after the 4Star. It looks like a great model.

What servo torque amounts are recommended for the 64? Are metal gear servos required for this airframe or will karbonite work?

Standard servos, so if you have Karbonite then it is more than plenty

Here is a quote from the IM....

you'll need two 12"- 24 long Servo Extension Chords (actual
length needed will depend on how long the wires are coming off
your servos plan accordingly), and one Y-Harness Chord for
connection of the two aileron servos to the receiver.
