That is a work of art. Fantastic.
How many hours do you reckon you have put in to that? Is it still balsa wood at that size?

Oh it’s the old 1:2.12765957447 scale!

I’d love to know what prompted that scale too please!

Had to fit in my trailer in a specific area, 1/2 scale would be to tall to fit, plus I use strictly 170cc twins and this size biplane (104" to 107")is just right.
My trailer is my limiting factor
If not I’d build bigger and it’s not required

Amazing!

I want one too! Turned out great! Is this one of those acrobatic planes that will never stall and can drag the tail around?

wow, you did all that on the burley?? How big is your cnc??

Naw not a good drag around aircraft like the 3D stuff out there now a days, it is an exact scale aircraft (as far as moments and shape) and is intended for masters class scale competition (designed for the Top Gun competition in FL). It is an excellent platform for true scale aerobatics that the full scale was intended for.

This was the first takeoff, it was very stable during the initial taxi tests

The first landing was really awesome, the CG, thrust and incidence setting I calculated around were spot on.

That is too cool. The motor sounds real/big not like I was expecting. Smooth flying on your part. Was there a lot of nerves or just excitement? All that work you might go either way on the maiden flight.

From doing this for may years one can actually tell how the aircraft will fly by how it’s actions are during taxi test runs at a speed just high enough to get the tail off the ground and on the mains.
But, yes you are 100% Ryan, it is still nerve racking when you spend some 1400 hours on a project and you never know what could happen

Wow! I am sooo jealous. That is an amazing accomplishment. It’s lightyears ahead of my foamboard airplane builds.
Congratulations on an amazing plane!

I think you can set up a crop dusting side business with that beast. :grin: It is very impressive and it looks like the real thing at that scale. Really nice work!
