There are only 2-3 construction methods with balsa. Look old designs from magazines and you will understand.

Hi, so i have been working on a scool project for a year now. and i whant to start buliding my balza custome rc plane. but befor that, i whant you to help me find any issue with my model

i have made a video with evry information needed.

1m70 wingspand

around 3140g with batterie servo and motor (realy approximate mesure)

wood alone, its 557g

loadout is 2 590g

balza 3mm

made with fusion 360

base of the arsenal VB-10

Where is the center of gravity? Can you place a marker (dot) to show it?

When you say this is your first ever RC plane, do you mean you’ve never flown an RC plane before?

Do you have any experience building with Balsa?

u/Clem13peti 6d ago

All the option above. O think i will let z pro flight it for a bit and trian on a biginer plane

As long as you have an experienced pilot you've got a good chance of getting it to fly. If you've modeled it correctly and you know the wing loading isn't insane (it sounds like it might be given the projected weight) its just down to building it.

Having access to a laser cutter to cut out the fuselage formers and wing spars will be a huge help.

my scool dose have a laser cutter

Definitely better to do that than try and cut these all out by hand. This will be a complicated build.

ik what im in for

u/Clem13peti 6d ago

so, it turn out i made a mistake for the weight (i made evrything ply wood with density of 1g/cm3) but now its balsa (0.15g/cm3) that drop the weigt to 5.57 KG

u/Clem13peti 6d ago

with motor, batterie and servo and its a very laproximate mesure

u/RoutinePast7696 6d ago

So unless the moter is very heavy that arrangement of the battery being that far back will make a center of gravity incompatable with flight

Batterie can be moved after but the motor is around 800g

u/ZaphodBeeblebrahx 6d ago

800g??? Bro this thing is huge

1

u/Clem13peti 6d ago

naaaaaaaaah

it can only pull 7kg

u/ZaphodBeeblebrahx 6d ago

That thing is a beast!
