Sure! I’d rather build this than the MS Corsair! (Just started stitching plans)

You mean the XL or standard? (Corsair)

Standard

 

[Houndpup Rc]

Here you go!

 

[Houndpup Rc]

Standard

 

[Mr Man]

Here you go!

Thanks!

 

[Houndpup Rc]

Thanks!

Yup! I will PM you the onshape file.

Gonna try to use black foam....

Gonna try to use black foam....

Cool!....Hopefully the paper doesn't come off when you are forming the nacelle cones...You will need to bevel those like the radjet and the edges of the wings will be done like Nerdnics speedwings. Also because you can't fit the servos in the outer wing sections you will need to run some coffee stirs thru the nacs and into the fus where your servos will be..

But what about yours? It kinda looks like the servos are right there....

No, what you are seeing is the end of the coffee stir...I know, its hard to do but I couldn't think of any other way! (I used a drill bit to punch thru the nac while looking down them...Also, make sure you get the nacelles straight otherwise you will have built in thrust angle so to speak.

And if you can run a spar on the wing span i think that would be a good idea...

Oh, I see what you mean, thanks!

Also, do you think I should run this as a tractor Twin Power Pack F, or a pusher?

It depends....If you want more scale looks I would do it as a pusher...but you will have to do more modification that way (And cut some spots out in the ailerons....) But if you want it to fly better and go together easier I would do tracker...It's up to you.

Yup! Also you may notice I moved the battery hatch forward to the next skin up..but not in Onshape.

Ok! I might not have to, because my electronics are lighter... But I guess I'll find out!

Quick question. Do I cut on the blue line, or black line? (I'm guessing black)

The black line and then you bevel and tape it like the radjet
