RE: Composite ARF Tucano Build
The stock CG location leaves the plane tail heavy. The plane flies fine, but just sort of "plows through the air" tail low. Moving the CG forward with 12 ounces of weight makes a world of difference in how the Tucano flies. You will notice a speed increase, better vertical performance and it is much more stable in pitch.

Hi Jan, I used the throws and CG location from the instructions and I had no problems the plane handled fine and had no bad habits.

I think it flies better slightly forward. Weight added will vary, but its a little too neutral at the manual figure for me. Some on this forum would certainly feel happy though.

Thank you all,
Is it at all possible for any of you guys flying the Tucano with the 12oz's added to let me know where the cg now is. It will be very helpful if you could give me a position at the wing root measured from the leading edge as I always balance next to the fuselage, rather than at the wing tips.
Finally, what size smoke tank are you guys using (while the standard tanks are used as intended) and where have you installed it?
Cheers,
Jan

RE: Composite ARF Tucano Build
Dave,
You made an excellent point. Different people like their planes to "feel" different to them. Some guys like tail heavy, some guys like nose heavy, some guys fly fingertip with monster deflection angles and some guys fly thumbs with small throws. To each his own I suppose.
That being said, for the Tucano to fly at it's optimum...it needs to have the C of G forward of the factory recommendation as mentioned in other posts. Sure, it flies OK at the stock setting and there are no doubt some who like it there, but it flies "much better" forward of the mark IMO.

What is the weight on the nose (scale leveled with the main weels) after you had the plane on a great CG? I find that to be the best way to get a correct CG. I will start on mine this week!

this is a VERY poor way to balance a model. with so many having such a big difference in their dry AUW this method of CG can be off quiet a bit.

RE: Composite ARF Tucano Build
Leo,
Mine weighs 4 pounds 8 ounces on the nose wheel.
KC brings up an excellent point in his post, so keep it in mind. The weight will only be a good reference if your dry weight equals mine, which is 42 pounds. Depending on how you build your Tucano, your weight might might be quite different from mine. I know of some other Tucanos that weigh well over 50 pounds dry, and in that case, my numbers would be useless.
Build your plane as light as possible, because no matter what power plant you choose (but of course I recommend you use the new Jet Cat V3 Turbo Prop motor), you are still ending up with a 100CC sized airplane that weighs over 50 pounds at takeoff power to weight wise.
Let us know how it goes and have fun!

RE: Composite ARF Tucano Build
I'm not sure which brand I used they were a set I had laying around in the shop; they were one inch throw I believe. I would recommend Ultra Precision cylinders. There are many other brands but they seem to hold up well over time.

RE: Composite ARF Tucano Build
Concur. Don't try the factory method...use door cylinders. I used BVM on the Tucano (OK...Bill Hatcher installed 'em) and my Lightning used Robart. Just pick a good quality unit (UP, BVM, Robart) and you will be fine.

My CG is set at the wing retaining bolt, and that is spot on.
A few pictures of my cockpit and pilots made by Maff's CAV.

Hi Martin,
How did you get in touch with this guy? I have emailed him several times with no luck.
Thanks, your cockpit looks just like the real one.

Peter Agnew has let me know my SPT-5 has been shipped, and my Tucano kit is ready to be shipped in the next container to Australia.
The long(ish) wait is nearing it's end!!

RE: Composite ARF Tucano Build
Jan, I balanced my Tucano at the wing retaining bolt position, and with the batteries mounted as far forward as possible I ended up with app. 100 G of weight in the nose.
My smoke tank is a standard Tucano fuel tank placed below the aft fuel tank - see attached pictures.
Regarding the cockpit, just write Matthias again - he will answer you. He made my cockpit and pilots. The helmets were painted by a friend of mine.
Having said that, I know that Matthias doesn't really want to make cockpits anymore, so he might decline your order.
You can also trywww.noll-modelltechnik.de - they do make instrument panels for the Tucano.
Also have a look atwww.inzpan.com - they make great cockpits.
Best regards,
Martin

Beave, Interesting, why do you use a UAT on the smoke side? Must say I like the servo output horns that you have on the rudder - please can you tell me where to find them? Cheers, Jan.

Jan, The servo arms on Bevar,s Tucano came from Air Wild.
