Very nice indeed. Is your PC-7 from a kit or plans?

Wonderful! Tell us more about the retracts.

Way to many airplanes!
Wow, VERY NICE! The whole airplane look great, and yes, I'm also curious about how you did your retract system with only one servo (for 3 wheels!!!)

Well, I see you like it.
This is not a kit. I draw the plans.
the retractable landing gear is very simple.
I had already seen on other model.
It is very lightweight and easy to do.

Wow, what an amazing plane and great details. Did you build the body from balsa?

hi Buratino,
the PC-7 is constructed so traditional.
I used Balza 0.6mm for body and horizontal tail and vertical.
for the wings I used 0.8mm Balza.
the nose is thermoformed as well as the nozzles.
the same for the canopy.

Hi carbondragon, what an incredibly accomplished build! It's such an unusual subject and such an incredible finish. Those retracts are straight from the watchmaker!

That carbon prop looks fantastic too. Is that hand made or off the shelf?

Many thanks for sharing the build and the plans.

Balsa, clean and detailed, and scratch built - hard to beat that. The retracts and pilots are a nice touch, whats the ready to fly weight? Thanks for posting the plans too.
