Nakayan,

Thanks For the Data Info/CoG

You wouldnt happen to have the slices from the intake or the canopy cross sections?


Im building at 100% out of foam. Hopefully a bit lighter when completed.

Some pics included

I've built some of "Beanie's" builds. That uses formers on a plan form, and skins.
Nothing like this though.
I mainly wanted to get my feet wet with this style of building.
As im wanting to develop some of my hot wire designs into short kits,wanted to see how all this works.


Got her off the jig last night so I can begin skinning the bottom.

I saw part of the video ... those guys did not put the airintake, only the lip. I think I am going to use same system, simple and less weight ....fuselage is big and there are no problems of air flow. I have 2 cs 10 blade with outrunner for 4s ready...dinamically balanced...

Moving along quite well

It has been awhile doing skins like this.
As my brother worked out the wing
I tackled the rest of the skins on the fuselage,

Now the wing was a pain in the bum!

Nothing seamed to line up with the wing plan.
Chord Spar was like 2 in longer then plan, once cut
Many ribs just didnt line up when inserted to the spar when over layed on the plan
Feet/riser location off on the plan.
Washout seams to take a wicked step up instead of a nice smooth taper or angle
Leading edge didnt seam to flow in a nice straight line either when set on the feet

A lot of work went into figuring all this out and to correct these. The overall wing panel great! My brother did a bang up job on it.

Im not knocking the free plans at all.

But when i imported it to cad these problems arise there as well.
I mentioned back on the first page i was seeing some errors.

Then Nakayan, chimed in with his laser cutting vid,etc....

Majority of the fuselage cross sections, you can run a dividing line down the center and nothing matches as far as left to right.
Another words if i mirror one half of a former, it doe not match the original.

If i was to take a guess, the 3d model was done as a whole, and not 1/2 then mirrored so everything is symmetrical.
So one has to make sure everything is level then jigged while your building! Do Not count on the notching and interlocking tabs, chekc double check triple check then glue.

This one is not fo the indeterminate builder that is for sure

They are free, and i know how much time it takes to model and cad for RC plane so ill take it as it has come to me.

Its another reason why i went with foam. as i didnt want to plunk down the cash for a laser cut to find all the headaches which i knew was there.

@ QQHeaD

Did you notice any of these problems, or did you do foam cores? Cant tell from the flicker images.

Weight will determine that for me.

I'm leaning toward the dectrum 70's
for 4s/5s, comes bundled with esc's and servos an added bonus.

2 of these units weighs as much as 1) 10 bladers

Anyways more pics.
Thanks again for the set of plans Nakayan !

Awesome! Amazing! D_FAST

Do you need data of the intake lip?
Please stick together with a thickness of 3 mm balsa.

Enjoy!
