I used the brass tube for strength but also if I needed to take him out, it's easy to slip another tie wrap through. I then have a tie wrap around his neck that goes straight through the seat to keep his head straight. It's hidden under his collar. For the tubs I made two tubs slightly larger and deeper then the vacuum formed ones and cut those out. Made them tubs out of balsa sheeting and then glassed them. they're really light and used a slightly heavier cloth for some strength. I then cut out where the legs would come through and drilled some holes in the back of each tub. This way the turbine can draw air through the cockpit.. well... that's what I hope to have happen.
Hey Thanks Rbgetz for your great description and photos. If you don't mind I'm going to copy your creative design.

Thanks again
Alan

No problem Alan. The carf vacuum tub was wide enough at the top, but narrowed as it went down. So I wouldn't of been able to get even small side panel in, beside the depth not deep enough. My front tub sits only about 1/8"-1/4" above the wood bulk head on the wing tube, and the rear tubs sits about 1/8" above the rudder servos. so much lower then original tub but still good fuselage airflow.

Thank you ! I should have know to see if Alex had something at Iflytailies.... I am finally getting back to having some building time to finish my own Tucano cockpit !

when people say they added about 8 oz of weight to the front of the aircraft once balanced as recommended, where in front? 8oz in the nose under cowling is different then added 8oz in the fuse by the firewall. I'm assuming you mean in the fuselage up front as close to first wall as possible?

It depends on how you placed your radio equipments inside the fuselage and on the turbine you choosed. My plane needed 120gm in the tail to balance. Others (I have seen) were adding lead on the engine mount rails in front of and behind the turbine mounting bolts.

Great Point Azzam... I have the SPT-10. I've placed all equipment so that balance seems to be coming out right on the recommended CG. I just needed to add my light controller and battery which are around 8-10oz. so I was going to place them as far forward as possible inside the fuselage.

It looks great congrats 👌🏻
did you have overheat issue with the cowling? and what about the CG, did you add any weight? and where did you place your batteries?

You can’t see in the pictures, but there is a Louvre in the cowl top and more in the fuselage base.
Balance with the SPT-10 and 5 blade prop is perfect. Powerbox Powerpak batteries in the cockpit area.
Model was built and owned by Andy Roshier, im just lucky enough to get to fly it a lot 🙂

Cheers 👍
I have K-100 on mine and I didn’t fly it yet. I’m worry a little bit about the CG. I’m planning to put my batteries in front of the rudder try.
I’m using 2 lipo 5000 amps for the powerbox, and one life battery with 3000amps for the turbine.

Sounds like it will balance fine.

Just curious on the 5-blade prop. I'm still running the 3 blade with my SPT-10. Has anyone run both 3 and the 5 blade and is there any performance difference? I was thinking of trying the 5 blade.

With a SPT-10 and a 5 blade my biggest concern was the additional strain on the firewall. I reinforced this with additional carbon fiber layup on the inside of the fuselage. I also made some gussets to spread the load a bit also. I tend to fly my planes on the high-G side and always reinforce everything where it may be structurally advantageous to do so ..

Always nice to see Voy flying! Nice!

I’m dying for a turboprop. Soon!

Are you able to check if there are any weight that added to the rear o the fuselage ?
I tried to balance mine in it looks like nose heavy!!!

No tail weight​​​​​! The manual balance is a little tail heavy, so sounds like you have a good position if it’s in front of that

I hope so. What scared me is when I put the plane on the ground and try to lift the nose, it feels too heavy like having a big brick in that cowling 😂
I did place my batteries “500 Grams” just behind the CG point and balanced it as I mentioned earlier, it’s still looks nose heavy.

Thanks Dave for the response.

Correct, the tai, push load is high...it still floats off the ground with the correct flap setting

Default CARF Cockpit

Hello folks

I'm new in this forum writing from Germany.

I purchased a Tucano from CARF and I’m wondering how to fix the cockpit which was sent.

I ordered seats from ScalePrint, a Pilot from Tailored Pilots and the instrumental board from Noll.

The original cockpit shall be glued inside of the canopy? Unfortunately I can’t share a Pic just right now. I need 10 more Replies ;-)

hope to find some answers. I can also share some information by what’s app I needed.

cheers

Hello Mauro. I have many picture from by cockpit build on this thread. There's very limit room. You still need to make sure the airflow through from the back. I had to add more air vents or at full throttle the turbine sucks the canopy in. But I love this plane and fly it the most.

Have a look at rbgetz's post #517 on this thread. He helped me with mine with his pictures. Good luck.

dear Rob
thx a lot. I already printed out your pics.

still a question: the 2 ends from the cockpit remain inside the canopy and the 2 middle pieces where the pilots are sitting in, are remaining below the canopy?

step 1: put the pilots in the fuselage and then, step 2 put the canopy above them and secure with the bolds

OR have you glued the pilots sections inside of the canopy?

Cheers

BTW: which seats are you using and which Pilot SIZE?
