The wing is 20" but what is the wing cord? is it 6" plus 2"aileron? and is it 20" from the center of the plane? And how far from the front of the plane is the wing to be placed? GOOD looking plane.

[ExperimentalAirlines]

@Flyrc27 I added the specs to the description. The 20" wing sections are joined to the center section right at the fuselage verge, so it's 20" + 5" + 20" for 45" total wingspan.

[MyCrossfire1]

Very nice cargo plane. Do you have any plans you can post?

[ExperimentalAirlines]

@MyCrossfire1 I do not have plans but it wouldn't be too hard to make using the video and a little creativity. It's just a two-piece candy bar wing on a box fuselage. I would be happy to help you in the process if you want to PM me. Also see bhcnomo (in comments below) who is also building one.

[bhcnomo]

what is that netting material on the para-shout from ?

[ExperimentalAirlines]

@bhcnomo It's called "tulle" (pronounced "tool") and is very cheap at fabric store. The parachute proper is nylon "jacket liner", which is about $7 per yard, good for 4 parachutes. Look out for parachute video soon.

[bhcnomo]

i just check the angle of the cutoff

from your video and its about 20

[bhcnomo]

whats the angle on the cut off at the back of fuselage

looks like about 30

[bhcnomo]

thanks ExperimentalAirlines for the info about the parachute

i need to know what the cord size on the main wing is

and the dimensions for the tail are

iam making a copy of your RC-69 Cargo Dropper

got the 5" tube made up for the fuselage tonight

and it was real easy

will be posting a time-lap video on my youtube channel as i go

thanks again
