Anybody else scratch building tonight?

[Bricks]

Unlikely nobody in my club are into combat.
So it's just for slow aeroatics or flat out speed with the alternate motor option

That is what I thought about my club as most were balsa builders, boy was I wrong. My nephew and I did combat just between the two of us to start. What made it really take off is Mike took it on to himself to build DT combat planes and sold them for $20 a piece install your on electronics. There is only three guy`s out of 39 members who does not fly combat now.

Ran out of tape so I couldn’t add the decks and canopy, but so far so good
This thing is gonna go on 4s!

Just completed paint on one build and next cut out ready to go.

Wow, how many leagues under the sea does that go down to?

Is that. P-40?

I found broken spirit level

great re-purposing

I have heard that the Spit' is an excellent bird. You're gonna love it!

Miniac RC's P-40

Thanks - the one ready to build is Griz's mini Spitfire - recently completed this Grifflyer ms mini (mini) Spitfire also - was a good build and been great fun flying it.

Have to build an actual FT plane at some stage!

I didn't like the old Microjet V3 motor and ESC after they made some weird noises last flight. Installed a FT 2207 Radial with a 6x4.5 prop and a new 30 amp esc with a working brake. Now the thing can handle 4s.

And the Goblin got a big brother. A Reptile Dragon 1200. That is getting a Mateksys F411-WTE, 1.3 ghz video, yadda yadda yadda.

The last one I made was the Taiidan Assault Frigate. [EDIT]: replacing pic of someone else's Frigate with pics of my Frigate. I made it so the turrets could swivel.

Oh yeah, I should probably mention; the reason I made a paper model of the Taiidan Assault Frigate was to help me suss out how I can make a flying one.

I'm wondering if there is a way to set up a big induction fan in the widest part of the hull; I'm thinking a contra-rotating pair of 9" three-blade props, which are then ducted to the nose, tail, port and starboard parts of the hull. The challenge is how I vary the thrust on the ducts for roll and pitch control. Shutters on the ends of the ducts will have the most immediate effect, but may cause turbulence and compression inside the duct, wasting energy. Shutters immediately below the fan will more efficiently divert air flow to the other ducts, but will that cause lag on the control? For yaw, I'll probably need some kind of bow-thruster.

I just think it would be cool to make a ship that doesn't use a conventional quad copter system. And two big props inside a big hollow model is gonna make a cool sound! 😃

Ok, happy flying!

For yaw, hou can do what those cheap chinese helicopters do. You slow down and speed up one of the motors so the one's torque overpowers the other and thus spinning the craft in a controlled and simple manner.

Speed of control has typically been solved with built in stability. The more stabile it is, the more lag and less thrust you would need

I thought that at first, but then wondered how much torque a 9" prop inside a duct could generate. I guess if/when I build something like this, I'll try the torque-yaw approach and if that's too weak, I'll stick some 3" props in for a bow/stern thruster couple.

Those big props will produce a ton of torque. Much more than 2 little drone motors.

Those nine inch props should be nust fone for a light model, but that is why we test!

Might add some more details and whatnot later but its gonna move.
But it’s infinitely nose heavy so that’s gonna be fun…

Looks fast. Is that a scratch build?
