Default Patriot in process

Hi all, as many of you may know, i had a patriot and loved every minute of flying it. I lost it due to a mid air![]
Decide that i cant live without the thing, so bought a .40 kit and am currently building it. I'm powering it with the West Eurotech 50V1 which i will mount conventionally (upright) with the pipe going down the side. I am aiming to make this patriot, look as much like a Bandit as possible. I've reshaped the tips of the tailplane and fin already, wing tips will also follow. I haven't got the reshaping planned, I will do as I feel necessary.

Main question so far is, as I'm going to be using a simple Take of dolly, and will continually be landing on grass, should I re-enforce the bottoms of the wing ribs? Although my landings will be perfect i thought i should take measures to stand up to the odd mole hill etc.......

I'm planning inboard flaps via torque rods, and a servo per aileron. Also if i can get hold of one, a smoke system.

The colour scheme will be the same as the Super Bandit shown on Bv's site (gloss black top side, white/grey underside)
Wings will be covered, main fuz will be glassed and sprayed.

let battle commence

I love the Bandit, Viper, and Maverick! You are MR take off-dolly eh?

I was gonna ask why mount the engine vert. but without gear, I understand--- I would reinforce the entire bottom of the airplane but I would hate to see it get chewed up...

You gonna use .75oz. glass? Be careful that it does not come out too heavy (extra servos inc.)

Yep, now that i've found a successful dolly style, its them all the way

I haven't glass finished a model before so do not know what cloth to use (was going to do some research)

If you'd like to give me some info on cloth and resign types and application methods..........I'd be very, very grateful

I'll post build pics/progress on my website, so should be updated daily.


Cheers
Dave

every plane i have had with gears on bottom of the wing.
the rail or that gear holder block cracked overtime.
except for my contender

i thought about using a piece of aluminum as that block.
but thought about it...the alumnuim would rip from the ribs anyhow.

i reinforced mine...i ran a piece of 1/2 x 1/4 sprut
from rib 4 or 5 to the root. i also jointed it with a piece of sprut
at the center of the wing...a secondary spar. i wasn't too sure
about the main center joint piece anyhow. overkill maybe,
but my contender was like this.

i also use the other pieces for the retract's ribs doubler.
it's triple ribs, now.

i epoxy hard tri stock all around the block and a piece
of ply to the block itself.

i also put a coat of epoxy on the rails...hopefully
that'll help it from cracking.

don't how much wieght it added, but it's lighter than my
p51 wing with retracts.

the secondary spar is glued to the landing gear rails

i also hollowed the top deck block, the wing tips.

i didn't use that big belly balsa block...instead built
it with sheets...got sick and tired of carving.lol
plus it made up for the wieght i added for re inforcing
the landing gears.

i thought about those control tips.
i made them run the full length.
this way i didn't have to worry about gluing them on straight
or at the porper angle.

i didn't install the fake intake..those thin pieces
and adding piece of scrap to fill in .
puddying and sanding and harder to cover.
no....thank you.

it'll cuase drag and i'll probably grab the fuselage at the center and
break it later.

it looks fine without it, plus the long budweiser logo was easier
to apply.

Should i install the u/c blocks anyway? or just re-enforce the ribs? I'd prefer to just re-enforce the ribs.


*EDIT: meant ribs again

if your talking about the wing joint block..i'll have too.
the spars joints at an angle.

the wing is glassed at the center.

the belly block is just for looks.

i don't think the spar needs reinforcing, but if you think it dose.
you can install shear web on both sides of the spars out to
the middle of the wing.
my GP mustang wing is like that per instructions.
GP f15 has a secondary spar (like i did)
or go all out and get carbon fiber.

my main concern was the that little block that the gears (music wire)
goes into. it'll either crack or get rip from the ribs.

i choose to add expoxy and re inforce now rather than later.lol

I meant the block that the u/c legs goes into

I'm not having u/c, so do i need to install the block? or just strengthen the ribs?

*EDIT: I really had spars on my mind

i killed three birds in one stone.lol
the sprut (secondary spar) i glued to the landing gear rails to
the root helps spread out the load (rib) during not so soft landings
plus it acts as a second spar and strainghten the rails.

that block keeps the gear in place or prevent it from piveting
or rather collaps.

my bad...take off from dolley.. don't need none of that..

glass the entire bottom..maybe add a 1/2 skid at center.
add wires or skids to wing tip

Sorry, I got confused in my first post on this thread by saying spars......when i meant ribs..........sorry, it was later that night......and following day :-)

I think all i'll need to re enforce is the belly.
