Looks good. What propeller do you have on the Wren?

How does the Tucano compare to the JMB PC21?
I had three flights on Saturday, all with similar landings...so far so good!
I’ll check my turbine readings next time I run it up, it does seem strange that my flight times are lower than others out there. I’m generally flying half stick with full for the vertical climbs, so nothing outrageous.
The Juniaer Tucano is a far superior finish to the JMB PC21 and a more manageable size. Having said that, the PC-21 was a very easy plane to fly and the landings were super slow.

I’ve installed a CARF smoke tank to increase the fuel capacity by approximately 1.4ltr.

Looks good, I like how you have done the aileron and elevator linkages.

Yesterday, I flew mine for the first time with the extra fuel tank and achieved 8 minute flights with enough fuel for a couple of go arounds.

I had 4 flights with my Tucano last week. I still have to tweak the flightcontrol settings but it flys great. I have my timer on 6 minutes and after landing I have about 50% left in the fueltank with mixed throttle settings.

Tucano’s 3 firsts flights done today. What a great plane ! It flies perfectly, the Wren44TP fits like a glove.

Ailerons travels have been reduced compared to manufacturer recommendations, and a litle mix Flaps -> Elevator down is added. CoG at 130mm is a good way as basis. Slow down and landing are easy with little more flaps than recommended.

I will communicate my own settings as soon as definitely validated.

Stéphane

Hello,

Some details about the K45TP engine mount modification to adapt WREN44TP.

I think photos are self-explanatory.

Engine frame is made in sandwich Carbon 200g / 3mm Plywood / Carbon 200g / 3mm Plywood / Carbon 200g. Total thickness: 9mm

If necessary, I can supply the engine frame design in DXF file.

The gluing area of engine frame is reinforced with epoxy resin + microballoons filling + carbon cloth. Sorry, I forgot to take photo of reinforcement....

Upper engine hole is drilled in 5mm diameter, linked to the main fuselage frame with 5mm x 150mm length screw, with aluminium spacer 7x5 mm diameter.


Stephane
