Quite amazed thay I couldn't find another build of this one, nice price, very well built. Mine comes from Sussex Model Centre very nice to do business with.

I haven't had time to weigh everything yet, just a few glances to check overall covering and quality of details and I must say I'm very impressed, beats the Funtana hands down on everything and that at a price of £89.99.

Motor for this one is Aero-Nuts 4120-710 :

Input Voltage : 7.4V~18.5V (2~5S Li-po)
Kv : 710 rpm/V ± within 10%
Nb. of turns : 12 Delta
Max. efficiency current : 25~40A
Current capacity : 55A/60s
Internal Resistance : 22 mohm
No Load current @ 7V: 2.67A
Dimensions : 50mm X 55mm / 1.97in X 2.17in
Shaft diameter : 8mm / 0.31in
Weight with cables : 301g / 10.61oz
Number of poles/magnets : 14
Recommended model weight : 2000~4000g / 70~140oz
Power equivalent : .46,2stroke

Data taken from Aero-Nuts

ESC isn't decided yet, probably Aero-nuts Platinum series 60Amps Brushless (which is the same as H-Wing Pentium 60amp Speed Controller , I've got both) or hexTronik BSC 60A Speed Controller which I also have. Hextroniks Pentium and Aero-Nuts Platinum is programmed in seconds with the Programming Card the S60 is more trial/error through the radio, not too much fun

Either one will be used with a external BEC circuit, Koolflights or Hextroniks.

Data for platinum/Pentium ESC:

Cont Current: 60A
Burst Current: 80A
BEC Mode: Switching
BEC : 5v / 3A
Lipo Cells: 2-6 (Aero-Nuts rates it 2-4S, 5S with proper cooling)
NiMH : 5-18
Weight: 44g
Size: 56x28x15mm

LiPos are Aero-Nuts 5S1P 18.5v 4100mah 13C Continuous.
I suspect they are the same as Hextronik HXT D9 4100mAh 5S 12-20C.

Data for LiPo:

Weight : 543g / 19.15oz with 12AWG wire
Size : 133 x 44 x 42.5 (mm) / 5.24 x 1.73 x 1.67 (in)
Continuous current : 13C/53.3Amps
Burst current : 15C/61.5Amps

Im going to give Graupner CAM props a shot, 8mm bore, easy to ream to 10mm with plenty of material left.

I'm using Jamara Servo XF-Mini 27gr this time too, dirt cheap but powerful and reliable.

More to come ...

Everything has a nice tight fit.

Aileron servos are mounted in the servo cover, mounting blocks included.

hi Peter,

I'm happy to see somebody building this airplane,
I plan to build the same but I didn't find much information about it,
so it would be very nice for me if you could give me the actual weight (not the one written on the box),

best regards

Michel

Vertical fin slides in nice and easily, no need to correct anything 100% lined up and 90°.
I have more concerns with mounting the motor, it doesn't say anywhere how far from the firewall the propmount should be.

Michel,

I keep forgetting to bring the scale out to my workshop, I'll weigh everything next time (this weekend).

//Peter

I wanted to know too

Fuse (including horisontal stabilizer and vertical fin) 703gr/24.79oz
wings (including joiner and belly pan) 708gr/24.97oz
Cowl 62gr/2.19oz
Landing gear 80gr/2.82oz
Spinner 33gr/1.16oz
Hardware pack ~75gr/2.65oz
excluding wheels

1661gr/58.59oz empty weight

Hi Peter,

reading a bit of everything on the forum to get ideas for future projects, saw your nice motor mount, is it this one:

Will need one for my YAK54.

Yes, that's the one.

//Peter

thanks a lot Peter for the weights,
btw are there wheels in the kit ?
may be you plan to replace them by lighter ones ?

Michel

The wheels are included but they're the first things to go, I fly from a little rougher strip so I usually replace them with +80mm ones, those included are usually 55-60mm. makes a lot of differance. As things are now I'll be making skiis instead

//Peter

I reused the two lower holes, enlargening them slightly and drilled two new for the upper mount. I also took up an airintake to get some airflow over the ESC into the fuse for cooling the LiPos as well.

I gave a thought to ordering Great planes motor mount which looks very nice, but I stuck with the ones I got (3DHobbyShops ). These are very sturdy, and takes up no space making it easy to mount the ESC in front.

//Peter

I have a feeling that this one is going to be a lot faster than my previous ones
Alex B had a 1m Tucano a while ago and he said it was very fast, I'm starting to believe this is going to be the same. Wing load is calculated 25.14 oz/sq.ft (from a calculated wing area of 567 sq.in) which is much more than my Pilatus PC-9.

After all it's a Scale Jet trainer so I should not be surprised

Calculated stall speed is 24.8 mph and if I remember correctly from Guapoman2000's lessons you should have a pitch speed of at least twice the stall speed, drive calc estimates a pitch speed of 60mph/96kmh with a APC-E 12x8 and that's the way I'll go. It also predicts 911W@55A which is just about what my LiPos will handle. So much for calculations, I'm more of a "real world experience, trial/error person" myself but I'll think it's safe to say I'll need more pitch than 12x6.

If I crash this one (most likely ), I'll get another Seagull Pilatus PC-9, I still miss that one.

//Peter

The wing halves is glued together. As usual the recommended way to remove the covering on the root rib is a knife, I still use a soldering iron to "cut" the covering, the edge is automatically sealed and the excess covering is just to peel off.

The Bandit (see blog) arrived to day so I got very busy to get the wing ready so I could get it off the work bench

//Peter

The Tucano suffers from me getting the Bandit hotliner yesterday

I'll just finish the assembly which should be fast and it doesn't need any skiis either. Then I'll return to the Tucano.

//Peter

Now the Bandit suffers

To avoid getting too heavy I'm thinking of putting in the same motor I had on the PC-9, Dualsky 4250CA-6 840kv, worked fine on 4S 4500mAh 12C 12x6 APC-E ~43A, 600W, this time with 12x8 APC-E and 4S2P 4400mAh 20-30C, Amps will be up but so will power too (57A, 757W WOT according to motocalc).

Weight save will be 169gr/5.96oz wing load closer to 20oz.sq.ft than 25

//Peter

hi Peter,

finally I purchased a Tucano, my motor is a HXT 50-55 kv500,
with 6s 4100mAh 12C and a Graupner 3 blades 12.5x7 I measured 39 A,
yesterday I couldn't resist as the weather was fine to try the maiden flight,
a 5 minutes flight without problem except the landing a little bit too long as the wing load is high (about 29 oz/sq ft, 88g/dm²) but without damage,
I didn't use ailerons as flaps for this first landing but I think this is a good solution I will try soon,

Michel
