Ultra light Yak-54 plans on the drawing board

[Malves]

The Yak-54. One plane that always wanted to fly, but never had the opportunity to do so. Tonight I found some schematics of the real thing and loaded it on the Photoshop. The goal is to keep it very light, so I decided to make a plan where most of the parts are already integrated. We have been used to building planes out of many parts because that's how the manufacturers have to pack and ship it - as small as possible. But since this is just a plan, then why not just cut one big piece? ;)
Only the LE will have CF. Size is 35"WSx28". LG will be 2 CF rods with pants/wheels made out of EPP or depron. Fishing line bracing instead of CF struts for the wings should keep it lighter, too.

Version 4 is here (http://www.rcgroups.com/forums/showpost.php?p=6166345&postcount=114) and pics in my blog (http://www.rcgroups.com/forums/member.php?u=35023), page 2.
Full fuse version is here (http://www.rcgroups.com/forums/showpost.php?p=5564460&postcount=90).
32" (800mm) version - my favorite - is here (http://www.rcgroups.com/forums/showthread.php?t=660452) and pics here (http://www.rcgroups.com/forums/showthread.php?t=749711)
32" (800mm) final version - with no counter weights on ailerons and one CF spar is here (http://www.rcgroups.com/forums/showpost.php?p=10972290&postcount=256). Sorry I haven't posted this last year when I revised the plans. Pictures from the above link are of this version.

looks kool

[Malves]

Thanx, bro. Here's the prototype plan. I'll post the plans in pdf format, after I build, test fit, and fly it. :)

[3dflyindan]

looks nice

them counter balances on the airlerons are a bit small ;)

But since this is just a plan, then why not just cut one big piece? ;)

I think some/most manufacturers actually cut the parts so that they go with the depron grain so each part will be as stiff as possible. Because of the size of a full sheet of depron you can't always get a full part (ie wing) from the sheet without loosing strength by going against the grain. At least that is why I do it.

[3dflyindan]

thats a good idea i might try that the next time i make one :)

dan

[sequagl]

Your final plan is very good!
I like the idea to keep it as light as possible!
I'll whait for the Pdf files......i have a small CD motor and small lipo battery that are whating for a plane like this!
Thanks and ciao

[Alexandre Cruz]

I would duble the LE thicknes and use two flat carbon rods (0,5mm), it would weight almost the same as a single stronger rod, but due to inertia moment it will be much stifer and will slow down the plane a lot.

[Malves]

Thanx for the info, Tim.:)

Plans should be available this coming weekend, if it flies like I am hoping to.:D I just got home with some depron, CF and paint. Now I gotta go to Staples to print the plans. How big should be the counterbalance? Double the size? I've just followed the lines from the real thing.

I am not sure about double LE thickness. I've seen ppl that swear by it, and others that didn't notice any difference. I thought about it, but dropped the idea. But it's nothing that can't be done with the current plans.;)

Nao tem muitos brasileiros aqui no forum, ne? Acho que voce eh o segundo que vejo por aqui.:)

[Alexandre Cruz]

Não mesmo, a maioria deles voam planadores..... :rolleyes:

The ideia of dubling the LE makes a much stronger wing, I would try mostly because of that. You also my also not use wheels wires or carbon rods are lighter...

[Malves]

I won't be using wheels. LG will be composed of CF and foam. At low weight, you don't need a very strong plane. The inertia is so low, that in the event of a crash, the damage is not a big deal, if any. I've been flying a copy of the Futurion that has no CF at all, and the crashes that it suffered only required minor repair. Also, with such a low wing loading, I find it harder to crash that often. Unless you get caught by surprise when flying in 8-10mph wind, like I do sometimes.

Now, I've been thinking about the dimensions of this YAK. I tried to keep it as close as possible to the real thing using the schematics I have - fuse is just 1 1/4" longer than what it was supposed to be so I could fit the bigger elevator, thou. I've noticed that other designs have a longer fuselage. Like the Ikarus shocky is 4 3/4" longer than mine, and they share the same WS. Is there any particular reason for that?

[Alexandre Cruz]

Longer planes have more inertia on the longitudinal axel and so are more precise (yet they have more side area), the stronger wing would prevent flexing during hi-G manuvers or on rolling ones.

[Malves]

Fitting is good. :) Don't mind with the hacked paint job. Spray cans are the worst to work with. :rolleyes:
I think I need to enlarge the ailerons a lil more on the plans. It didn't come out as big as I thought. :rolleyes: Elevator is not in place because the rudder is not cut, yet. More to come soon.:) I need to paint the other side of the fuse and I think I am running out of yellow paint. :(

[Alexandre Cruz]

Very nice painting job. Biger ailerons may be needed for 3D but I think it will perform F3P well, usually I try to keep CG to fly inverted without elevator imput, this makes your elevator veeeery sensible

Nice plane Bro

[Malves]

Thanx, bro. Yes, that's the problem with the ailerons. I do more freestyle than pattern. Oh well, let's see how it goes. I don't even know if it will fly well, yet.:)

[Malves]

Wingspar is glued. Next is the nose. No matter what if I am building light or not, I always put tape over the spar. You can see that in the pic.

[Malves]

Nose's glued and ailerons taped. Next is fuselage, but I have to take my boy out. It's beautiful outside today. I think I may get a couple of flights, too. :)

[3dflyindan]

looks good

dan

[Malves]

Thanx, bro.:)

The frame is almost all done. I've glued the vstab/x-section joint before the fuselage joints to keep it straight. Also, make sure you draw a center line for everything. I didn't and it just slowed me down, since I had to work with rulers and squares to get it done straight. :rolleyes: Next is the LG.

[Malves]

LG is done.:) Now it's ready for the eletronics.:D

[3dflyindan]

loooks great bro

is the LG heavy i donno if it is me but i thought it loooked a bit bulky ?

dan

[Malves]

Nah, it's just 2 CF rods with 4 pieces of foam. That square piece that looks like ply, it's just foam.

[3dflyindan]

oki doki are the wheels real or just foam aswell ?

dan

[Malves]

Foam.;)

[Mister UHU]

The goal is to keep it very light,
so I decided to make a plan where most of the parts are already integrated.

We have been used to building planes out of many parts
because that's how the manufacturers have to pack and ship it
- as small as possible.

But since this is just a plan, then why not just cut one big piece? ;)


A nice piece of lateral thinking.

Less glue = lighter plane.

Also fewer pieces means less "building".
And I think some sort of "user assembly"
is preferred by manufacturers and customers.

I don't know how "grainy" your Depron is.

If it is too flexible in one direction,
you could re-design or stiffen it,
with the usual carbon, wire bracing etc.

[fwilly]

Putting the grain in the right direction is more about durability than flexibility. If you cut a shockflyer with the grain of the horizintal fuse perpendicular to the fuse, then it will break off behind the wing in a mild crash. If you fix the mistake by adding carbon, then you have added more weight than a glue joint to glue two smaller pieces of depron together.

[Malves]

I've put 9 flights on it already. I've been playing with the CG and I think I found my spot. I'll be doing some modifications to the plans soon. The wings need a spar on the TE, so that part will need to be cut. I will also modify the wing a lil bit to add more wing area and bigger ailerons.
I've used very little glue to put it apart, and assembly was quick. I have had a couple of dumb thumbs while doing torque rolls, but only the wing tip cracked. I was surprised to see that it is stronger than my Schocky Edge.
After I modify the plans, I will post them to anyone that wants to give it a go on the second prototype.:)
Even thou I'm having a few issues with stifness when doing maneuvers like rolling harriers, I still like the way it flies. I've been having a blast with it for the past 2 days.:D

[fro540]

malves...congrats on the successful build! ....looking forward to V2 :D

[Malves]

Thanx, bro.

I have just added the foam stiffeners along the fuselage from nose to tail. It holds the tail a lot better than bracing and it makes the whole plane a lot stiffer.:) I took it outside for a quick test flight and the maneuvers are a lot more solid. Specialy snap rolls and rolling harriers where I could see the plane hesitating sometimes and I had to correct it with control inputs. Now the plane rolls on its own, without the need of any correction. Next step is to add CF to the TE.
I may work on the plans tonite.

[Malves]

I am almost done with the plans and I'll upload them tomorrow night. This should be the final plans for it.

Now, I wanna share with you guys a 30sec vid of mine that the wife just took a few minutes ago. I live in an apartment so the space is kinda limited. The vid is just my lil Yak hovering in the living room. About 9 months ago when I opened the box of my first plane ever, that was a Flatout CAP, I put it together and tried to hover it in the same room. Yes, stupid and I paid the price for it with a cut on my stomach. Now, here I am hovering my own design in the same living room. :cool:

I started flying 9 months ago, but I had to take a compulsory brake of 3 months after I've lost my job during the winter. So, I basicaly have 6 months of stick time.:) I am really happy how much I've learned and improved. But even happier for having you guys here so I could learn and improve. Guys like Jurgen, Jeff P., Devin, papasmurf, Dr.Kiwi, John Glezellis, fwilli, Tim H., Tim from e-foamies, blucorbasher, mexico, to name a few. There are so many.:)

The vid is kinda crappy because it was taken with a crappy digicam, but you get the idea of how rcgroups transformed a stupid pilot in a good pilot - after all I can do more than just hover inside my living room afraid to cut the new curtain the wife just bought, with her shooting the vid.:D

Thanx for all the help, guys. :)

[3dflyindan]

well done mate

sorry i havent posted for a few days i broke my wrist on tuesday so been in hospital

dan

[Malves]

Thanx, bro.:)

Here is the plan for the Yak-54. This should be final. I modified the wings a lil with more area and bigger ailerons. Adjusted the cut on the fuse where the stab/elev goes in. Adjusted the elevator for more rudder throw. Broke the x-section in more parts to put 2 CF spars on the wing.

I would start with the CG at around 2 3/4" from LE and go from there.

I'll be putting a new one together over the weekend so I can check the adjustments I've made to it.

Enjoy!:)

[Brummeh]

I just wish i could "hack a paint job" like that :confused:

What motor and batt are you using in the video please?

I have a micro cyclon, 27g and 2s 400mah batt, will they be any good?

Mike

[Malves]

Sorry, bro. I don't know that motor.:( But it should be fine with the right propeller.

I am using an E-Flite Park 300 (24g), 8x3.8SF, and TP480PL 3s.

Last nite, I've cut a new plane.:) It's painted and ready to assemble. I'll post a pic later. My biggest problem with painting is the masking part, but I guess I found a good solution for it.:D At least for me. More later.

[Malves]

Here's my new Yak.:D I just took it to the basement of the building where I live for some hovering action (can you call it a maiden? :D ) and it did great. Of course, it's much better than V1 with the considerably bigger ailerons.:) I just love this lil Yak. :cool:

[3dflyindan]

looks sweet mate :D

dan

[Malves]

Thanx, bro.

Well, I did a real maiden today and...wow! The bigger ailerons made a huge difference. Rolling harriers are fast or slow, you pick.:) I am having a blast with it. It's a very responsive plane - I had to increase expo on the elevators. Hovering is soooo easy, that it is actualy the first plane I can hover in a small sized room. If you have a setup laying around, give this Yak a go. You won't be sorry!:D It builds quick anyways.;) I have the CG setup somewhere between 2 3/4"-3" on this one.

If you build the same way I did in the pics above, you'll have a stiff and strong plane.:)

[3d Dave]

Malves,
How much does your Yak weigh?
Thanks,
Dave

[racerxky]

Sharp looking airplane. Nice job. :D

[Malves]

Thanx, bro.:)

Dave,
I don't have a scale to weigh it. Probably gonna have to wait until the weekend. But I'm estimating ~6oz. Getting this plane at 5oz or less, shouldn't be a problem with the right setup and less paint.

[fro540]

looks really good malves.... will be building one beg. of next week when i get back from "business" in vegas... lol... you did use 3mm depron? v2... ws & length?

[Malves]

Thanx, bro. Yes, 3mm depron. Business in Vegas?! :eek:...Yeah, right!;) WS and lenght are still the same: 35" ws and 27 3/4" long.
I'll try to get a vid later if weather holds up today. I was flying a few minutes ago, but the wife's at work and I can't take the vid. I want you guys to see how this thing rolls.:D

[3d Dave]

[/IMG]
Here is a picture of my 152 gram Yak.
Strong R/C 20mm motor, Kevlar truss brace,
pull-pull on elevator and rudder, 1.5mm carbon landing gear, 1mm carbon aileron push rods, HS50 servos, cc10,
480 TP Prolite 2cell, motor puts out 310 grams thrust with a 8.4 gws dd. Best plane I have built yet and flys great.
Dave

[Malves]

Looks great, bro!!:) I like the paint job...simple and cool.:) What's the WS and lenght?

[sequagl]

Ciao Malves!
I just try to print your design...but i cant print it whith an A4 printer.
Maybe because i use linux and my pdf reader didn't recocnize well the file.It seems to be a non tiled file.You know any solution?
Thanks for share it!
By

[Malves]

Yeah, it's a full size plan. 36"x23". I don't have the plans tiled.:( Sorry, bro.
Take it to a local office supply store that does large prints. That's what I do to print large plans.:)

[Malves]

Anyone up to a full fuse Yak?:) I've decided to try it out, and I have the plans almost done for the first prototype. I am getting some depron tomorrow to build it. I'll have pics over the weekend.

[Malves]

So, what do you guys think?:) Still got some work to do, but that's it for tonite. 34"ws 28" long.

[Brummeh]

Grey 3mm depron, how ugly....

New motor going in later i hope along with 3 x 5 grm servos and a 2cell 400mah and 8 x 3.4..

Mike

[Malves]

Nice! Now you just need white or silver paint to do the canopy.;) Make sure to let me know how she flies.
How was the plan? Did the parts fit fine?

[3dflyindan]

i knew you were going to do a full fuse yak lol

did the plan i give you work?

looks nice by the way lol


dan

[Malves]

Yeah, after the tips you gave me on how to do it, I couldn't resist.:D Nah, I didn't try the plan, yet.

[3dflyindan]

lol keep me posted

dan

[Malves]

It's done!:) It's just a prototype, so I didn't apply myself to the paint job. :D

[Malves]

One more.

Note that I didn't use a firewall, but just a cross section - like in a shocky. I have 2 reasons for that. First, it's a lot stronger than just a firewall in case of a nose crash. Second, I'll have more air going inside the fuse that will slow down the plane (also, more air for the eletronics and pack).

[matchlessaero]

Nice job Malves. Your Yak turned out very nice indeed. :)

[Mike Williams]

Wow, very nice. I will have to build one to.

Michael

[Brummeh]

A bit late Malves but, the plans worked fine and it all fitted together o.k., i weighed it today and it was 139g without the batt, but its sooo windy in the u.k. so it still hasnt flown.

It looks like i need a full fuse now, any tips on building one please?

Mike

[3dflyindan]

i told malves how to do it LOL

add me to msn anyone daniel_deavin@hotmail.com

dan

[Malves]

I have the plans for the prototype in the pics. It'll need a few adjustments, but if you wanna give it a try PM me your email address and I'll send the plans to you. :)

[fro540]

lol... you are creating faster than i can build....

looking like the AUW of my v2 will be around 4 oz even... will have pics to post hopefully tom.... had to much fun with my current f3a style outdoor plane tonight to finish it...10.1 oz's of fun

has there been a maiden on the full fuse?? auw compared to v2?

[Malves]

LOL...Nah, I don't have an indoor site for maiden and it has been very windy over here.:( All I've been doing is hovering in the basement with it. :rolleyes: I don't know the AUW, but it is very light, too. I am estimating ~6.5oz AUW. It could be less, thou. The lil Park 300 hovers it just fine at 1/2 throttle or less, just like it was with the shocky version.

I've just started a new job this week and I don't know when I'll have time to make the few adjustments needed to the plans. I also need to fly and crash it :eek:, to see where the weak points are and make the necessary adjustments.

Tonight, I was stupid enough to bring it outside. When I let go into hovering, the wind took it. It hit the window of the second floor apartment (remember the 1st floor is half "buried" in the ground here), and down it came. :mad: Only damages were a loose CF wing support, a cracked wing tip (about 1/2"), and a lil loose motor mount (I knew it the nose would be much stronger with a shocky style mount; 2 drops of CA and it was back in place again).

I am really anxious to hear some feedback for the shocky style Yak. :)

[Brummeh]

Hey,

ive flown 2 batteries now on the shocky-yak. ...outside...

i need to get some more velcro on to take the cog back a bit as it dives inverted, the main thing is the roll rate is very slow, any ideas? with the throws i have here? it loops and turns on rudder tightly, ke esily, i just need more aileron.... and ill practice some 3d and see how it bounces..

Mike

[Malves]

... the main thing is the roll rate is very slow, any ideas? ... i just need more aileron....

Hmmm...the rolls on mine are fast. I have the tendency to do rolling harriers shallower than others, and pretty fast, too. It surprises me that the roll rate for you is that slow. :confused: By the pics, you have lots of aileron throw. What's the AUW? Remeber, even thou this is an indoor design, it's meant for freestyle not precision, so you gotta have some extra weight on it for inertia.

[Brummeh]

AUW is 176g, could it be too much wing flex and needs more carbon or bracing?

Mike

[Malves]

That's plenty of weight. Got a pic of the underside?

[Brummeh]

did i get a good angle? :P

Mike

[Malves]

That's a good angle, but I don't see any bracing.

Ok, now I see it.

Bro, I've tried bracing it, and it didn't work good. I moved to CF supports and it made a huge difference.

Or you could try to add another bracing point 1" from the wing tip. I thought about doing that, but just moved to CF.

[Brummeh]

LOL, there isnt any bracing, just cf on the le..

how should i secure it if i add it now then, just glue direct to the wings?

Mike

[Malves]

Ohhhhh, now I am seeing things, then.:D You need to support those wings.:p

Check pages 3 and 4. I have a couple of pics of how I've done the struts with CF. Puncture the wings and fuse, and CA in place. Also put some CA where the rods cross. If I remember, I have use .50 CF rods.

When you flew it, didn't you see the wings flapping?

[matchlessaero]

I'd suggest bracing the wings as well. When they flex, you are unable to get full deflection of the ailerons...

[fro540]

well due to a bad new rec.... and the delay for a replacement the yak is ready for maiden... would have been tonight but there is a solid wind here on the east coast tonight.... hopefully tomorrow night

AuW... ended up a bit heavier than i was hoping at 4.8 oz's, but that is with 3s450's... impressed with the potensky motor it feels like the plane will hover at 1/3 throttle... so may drop some weight with a 2s....

[Malves]

Looks great, bro!:)

[fro540]

thanks... hopefully my thumbs will cooperate tomorrow....lol... posted the wrong second pic.... to much ca floating into the brain i guess... current favorite outdoor plane....

[Jerry Combs]

fro540,

Just curious, is the outdoor plane an Amos Moses from BP?

Jerry

[Mister UHU]

... impressed with the potensky motor

it feels like the plane will hover at 1/3 throttle
... so may drop some weight with a 2s....



From reading the packing leaflet in one of the photos
I guess you are using P0T 30 ?

[fro540]

Jerry.... the outdoor is a somewhat copy of the ikarus f3a i recently smashed... bad thumbs strike again :rolleyes: .. lol.... changes: moved the canopy forward, added 10mm of aileron surface full width, additional lower fuse area, and decreased the forward angle of the rudder by a little less than 5 deg's... all 6mm depron, decent amount of carbon throughout... axi 2208/34 on hp3s700 etec's.... AuW is roughly 9-10 oz's depending on battery... fuse and rudder changes greatly improved KE, handles the wind pretty well which was the main plan...BTW thanks for the help with the bipe a while back, i added a 2nd ail. servo so i could set all EPA's which corrected the yaw prob... thanks.... off topic sorry :D

Mister Uhu... yes the pot30... feels very strong with a 7x3.8apc, bp esc, and etec hp3s450.... feels like it will want to rip the wings off, but it may be overpropped currently.... may have to drop to a 6"

[Jerry Combs]

Thanks fro540, I have an Ikarus F3A that has been the victim of dumb thumbs. It is kinda ratty and getting rather porky due to repairs. Thanks for the suggestions on things to try changing on it, I haven't been happy with the knife edge on mine and just figured that it was because of my poor piloting skills. Glad to hear you got the bipe worked out. :D

Jerry

[Mister UHU]

Mister Uhu... yes the pot30...
feels very strong with a 7x3.8apc, bp esc, and etec hp3s450....
feels like it will want to rip the wings off,
but it may be overpropped currently.... may have to drop to a 6"




The Potensky website is a bit confusing.

List battery as 2 X 340 mAh (ie 7.4 volts)
but Max Efficiency at 10.5 volts and 4.5 amps.

List Prop as 7" X 3.5" GWS
but also list data for 8" X 4" prop.

Say motor is for 2 LiPos,
but have data also with 3 LiPos.

Recommend 15 degrees timing advance.

Looks like you will have to do your own experiments.

From my own experiences there it quite a difference between
different types and brands of props,
such as slowfly or not.

I doubt Dr Kiwi will have tested the POT30,
but it is worth a look.

[fro540]

jerry... my stock f3a required a decent amount of down elevator to maintain straigh flight in KE... new version is much less rudder and little to no elevator... and trust me i have plenty to learn on the sticks... lol... oh one other thing i did notice last night that I am at about 3 1/4" back off LE for CG

UhU... the data sheet that came with the pot30 lists recommended prop sizes for both 2s and 3s and efficiency charts, my scanner just died or i would upload it... it does in fact hover at 1/3 throttle with the 7x4 apc, but the motor got to warm for my liking after repeated 10 second hovers last night in my garage.... unfortunately it was still to windy to test it outdoor :rolleyes:

malves.... yak hovers like a champ! :D

[Malves]

malves.... yak hovers like a champ! :D

Cool! what about the rest?:D :p

[fro540]

unfortunately it was still to windy to test it outdoor :rolleyes:

couldn't fly it outdoors....

assuming your in Mass., it is windy up there to right?? i check the surf forecasts all the time :D tonight is as bad as last night here 10+ mph... btw. been up to rcmadness in enfield conn. quite a few times for 10th and 18th scale offroad races... chris marcy is a great guy, good driver too for that matter, if you ever need anything.... is that close to you at all?

[Malves]

Yeah, it's been windy over here, too.:( It sux, because I don't have an indoor place to fly during this time of the year.
I am about 1:30h away from Enfield.

[3dflyindan]

hi

i just designed my own design on autocad 2006

tell me your honest opinions please ! ! ! ! ! ! ! !

dan

[fro540]

Cool! what about the rest?:D :p

happy to say i did get a short flight in last night before a Big storm... got it all trimmed out and was comfortable with it quickly, controls were clean crisp and predictable ... unfortunately, just as i was starting to have fun and push the plane a bit the new esc went up in flames, literally :eek: using the 6x4 apc on 3s it should have been pulling a little over 5 amps and the esc is rated for 8 amps so not sure what happened..... good news is that the plane is ready for indoors now :D thanks for the plans malves!

[RV6-A]

Dan , I think it looks Great , lets see it fly soon :D

[3dflyindan]

thanks mate

i dont think i will fly this design any time soon but everyone is more than welcome to if they want ! ! college and school commitments come first i may have my dad print me the plans and i may make one or two

more opinions please ! ! ! ! and someone make one please ! ! ! ! !


dan

[Malves]

It looks very nice, bro. Foamy Prodigy? :D

[3dflyindan]

yer sorta lol i just sat at my computer and me and my mate just thought it up as we went along lol :D turned out a pretty nice lookin design !

how your full fuse fly mate?

dan

[Malves]

It flies pretty nice. The stiffer fuselage gives it a different feel from a shocky style foam. I haven't flown it since last weekend. I've been really busy at work and don't have time to update the plans. It's no big deal of adjustments. For those who want to give it a try...

[Brummeh]

after a week of wind its gone dark and still here..

heres the remains after a 2s400 and a 3s900 battery in my small garden.. in the dark

yak vs. trampolene, washing line, tent & gravity... the 3s900 goes like a rocket tho :), and its only a few bits of depron short and still going.

Mike

[Malves]

Having some fun, huh.:D

[Brummeh]

Yeah, loads'0'fun thanks ;)

After 3 batts at the park with my 38" 6mm diablo i had another batt hovering in the garden in the dark again with the yak, no breakages tonite :P

now, was it luck or am i getting better? Hmmmm

Mike

[3dflyindan]

definately luck :P

dan

[Malves]

Anyone built the full fuse version? :)

I've edited the first post with a link to the full fuse version, too.

[Brummeh]

Im just cutting the full-fuse now, but do i do the tail in 6mm or 3mm??

Mike

[Malves]

I've done mine with 3mm.

Just a note...I am building v.3 of the shocky Yak. It has a longer fuse and increased wing and rudder area. Plans will follow soon.

[Brummeh]

Now you tell me :rolleyes:

Sorry, bro. I was gonna post the plans last weekend, but I wanted to see how it goes before I do. The full fuse won't have any updates.

Im doing the full fuse and a 6mm extra both at the same time, theres foam and mess everywhere...

Ive just got to work out where to put the electrics before i put the top and bottom on..
