Topic: Aeromod Alliaj Build

Aeromod Alliaj 1st style Not HM (hollow molded)
I thought I would do a build thread as others input is always helpful and sometimes you cant see the wood for the trees

Starting with the fuse
Need to find the C of G of the ballast tube decide on the position and how I will hold ballast in the tube

CofG marked
need to make up servo try
I make a cardboard template which allows me to F about with it till im VERY happy before making the carbon one up

I am happy with the servo try and the plan for the ballast
I have fixed the tube and cut the servo tray out

Practice fit the servo tray and make up the loom

Tonight it's the wings
I am still not sure weather to try to keep the servo cut outs

There are no servo covers for the wings so
a) buy some clear ones from T9
b) cut them out using the thinnest blade I can to reduce the amount lost and try to refit after
as is a foam wing I was thinking I would carbon the foam sides ion the servo holes, to look nice and add strength
then I could add a small strip of balsa to make a lip for the cut out cover to sit on, giving me a flush finish
??

no heat shrink on the wiring loom?

If you cut out the "covers" you could create a lip with a bit of ply under the wing skin for them to sit on.

doesn't look very 2.4ghz friendly!

There is no heat shrink on the loom because I plan to use hot melt glue and use the glue to fix them to the spar tube at the same time.

No it's not 2.4 friendly
but having a canopy rather than a nose cone means "whiskers" will be easy to install and as it will be my F3F plane I hope not to be specking out much anyway (though I have no worries on whisker range of a M-link)

Servo bays cut out with a scalpel to reduse loss in case I want to use them
Loom for wings made up but not inserted yet

Stop wasting time on this thread Allen & get on with building it! You can maiden then on Saturday at your favourite bowl at the Long Man. 

They are only forecasting it gusting between 27-37mph at moment.

Anyone got any tips to working with carbon cloth
I have lined my servo cut outs in the wings with carbon cloth

It was awful cloth just unwinds all the time
I did think about sticking the cloth on marsking tape, painting with epoxy and leaving on till dry?

someone must have some clever tips

too late for this job but there will be another time 

Cyano the cloth then paint the epoxy on.

Be careful about what your cyano does to the foam though!

Another method.

Get some plastic sheet. Wax one side a couple of times. Pop your cloth on it, and wet it out with a roller or whatever. You can really put some pressure on it and flatten the tows out nicely. Once done, use scissors to cut the carbon/ plastic sheet to the exact size/ shape you want whilst still wet. Put it in place, ideally leaving it with a little pressure on it to keep it there. Once cured, the plastic sheet will release off nicely leaving you with a perfectly flat shiny carbon surface.

Sandwich the cloth and minimal epoxy between layers of poly bag.
Spread the epoxy with a wallpaper seam roller, pressing the epoxy into the cloth weave for efficient impregnation.
Cut out the required shape with an Olfa Material Cutter, working to a previously prepared paper template.
Peel off the top layer of poly.
Apply the pregged cloth in place, rolling/pressing on the remaining poly.
Peel off the remaining poly, dab excess epoxy away with kitchen roll to make surface as dry as possible.
Press on peel ply (Dacron), if a key is required for future adhesion.  Leave in place until cured.
Remove peel ply and it's done.  Neat, clean and light.  Easy - even for an idiot like me.

Ro.

Spray it with '77 spray to hold the weave together, and treat as normal.

Cyano the cloth then paint the epoxy on.

Ok. That way wirks on HM Doh.

Loom now set in position I use hot melt glue instead of heat shrink as I thing it's better for this job, it hold everything in place as well as insulates it

I have made up the wing servo trays so the servo arm face down (towards the top skin of the wing)

I have used Epoxy board to make the control horns (not finished yet but you get the idea)

Do my whiskers look fat in this   

OMG wing servos make easy NOT!!!

What a nightmare not sure I can even get 3150s to fit with the internal push rod set up
your meant to put the servo in upside down (the arm facing down not up) to get the diagonal action on the push rod, so the control horn is on the under side rather than the top, but to get enough servo arm and clearance means the whole servo sits a few mil out from the wing 
a 3150 is only 10.8mil thick which in only 0.8mil thicker than thin wing servos
So I plan to either:
1) make up the smallest servo arm possible and  for enough movement
2) make up a glass servo cover that allows for the servo to patrude a few mil

Hey Allen

If that's a bottom hinged surface with that little black thing being the horn underneath the surface, then I can't see how that will work, other than with an absolutely giga amount of potential for slop and inaccuracy, as the horn looks spectacularly short. If I was you I would just do a conventional top driven solution with a cross over linkage. It's not hard to make an appropriate channel through the foam with a nicely warmed piece of relatively large gauge piano wire

They are all top hinged surfaces

Here's a fag packet sketch

oh icic - hmmm! either bottom/ bottom then or big aggro!

Can't be as bad as the prodij install can it?

Can't be as bad as the prodij install can it?

I liked the PJ install, I enjoyed the Aldij Eco build (inc cutting flaps ailerons etc)
I loved the fuse on this plane

but these DAMN FING WINGS 

That would be a yes

Just a quick up date
I have ordered some 2.4 whisker things to tidy them up and
some Brass Horns to replace the carbon ones provided

Thanks T9 Knowing rich I'll have them tomorrow 
PS if you do have some black ones you are showing out of stock, I would prefer 

I got my little bits from T9
Thanks again Rich for an amazing service

Oh and somehow a NCFM HP48 seems to have fallen in with the order 
Well it is Xmas 


Ian (Nimbus)
This Means I have a tatty old 60" Gulp that you can HAVE!!
It will need two servos as they are new and going in the HP but I can bring it on Monday if you want it ?
Im sure you wont say no to a freebi  But there is one rule you Must race it in any 60" race that comes to Eastbourne

Couple of guys at our slope have HPs. Goes like on rails. You'll like that. Be an easier build too

Hi Allen,

I really appreciate your kind offer, but think you should give it to someone a little more deserving! 

I do love the flying wings, but it drives me mad`er all the taping involved, & I remember the trouble I had attemting to strip my old Wildy. Also, I feel I am more cut out to the sedate soaring type of flying, as opposed to the lightning quick reactions you F3F`ers have.

Is that HP48 what JP` has?...If so,  they look like they sure motor!

Yep

And it is covered, just badly
I need some to have it that I know will dso there best to make it to the 1 or 2 60" we have and you seem to always make the effort to be at every event

Maiden today at the Longman in a 30-40mph  lol not the most suitable but 

OMG if anyone want to know what it was like and has once owned and loved a Prodij, well that is EXACTLY what it was like, was extremely responsive

I set her up as the book
launched at 75% dual rate, she was all over the place WAY TO MUCH movement,
second flight was 60% dual rates and two sluggs of lead, much better just a little to much down elevator and I may remove the snaps on the down movement ?

Congratulations Allen, hard to beat the buzz of a successful maiden, I look forward to seeing it in the flesh next time we're down your way.

you never know Paul, I might come up yours some time

  where was the double in that entendre?

by all means come along and enjoy the third rate lift of our local spot!

Ha,

l think matters are made worse by Allens use of the gimp mask emoticon/smiley after the wording.
