VR-1.1 Lutra - My First Design (second now) - Build Log

[Timmy]

Go for what you like the best! You'll have to make two nose skins for the 4th option since you can't easily bend the foam the other way in one continuous piece.

yeah

Here's a three view of what I got so far:

Looks good!

Next up to draw: all the interior stuff.

looks nice, but i would consider make the tail horizontal stabilizer a touch wider for better control, and with such v-shape at trailing edge, you need make either a y-shaped pushrod,or two servos for the elevator function.

 

[Timmy]

I want a stubbier nose for the looks but I will probably have tail heavy issues

ooh I hadn't though of that I'll figure out some kind of Y push rod. If not I'll make it less swept back

 

[Timmy]

I'll do that. Wait by wider do you mean to increase the chord span or wing span?

Nah, no worries. If you want, just cut the hinge straight across.

yeah but that dosen't look as good

 

[Monte.C]

Ok and if you need your hinges to parallel the training edge then split the pushrod.

 

[Timmy]

VS.

wing span.

 

[Timmy]

wing span.

ok

 

[Timmy]

This is gonna be a 4ch! Servos incoming!

 

[Timmy]

Second dilemma:
The fuselage is too wide and doesn't fit flat on one piece of foam. I need to make it thinner but then it starts to look funky.

 

[Timmy]

Currently I have a foam box spar running through the middle of me wing which is 1.3 meters long. Is just that foam spar enough to keep the wings from snapping?

I would add some wood to strengthen it.

 

[Timmy]

I've just printed the nose and part of one wing out and realised I'm making something the size of the guinea pig which is huge for me. I don't know if I shoulf contine or try and make it smaller.

CONTINUE!!! you could put the wing on 2 hinges on the wing to make it foldable and lockable
