*****My WOT4 MK2 Nitro RC Plane Assembly Log****

haha that fuel tank is dinky, whole engine is!

:p

Its the more powerful 2 stroke ;)


OK fuel tank completely set-up and tested for leaks by placing in a sink and blowing through all the tubes, looking for bubbles, abit like you would with a bike innatube. No leaking air :)

Got the tank positioned in the front of the plane alhough its not fitted properly yet, I have also fitted exhaust to engine and got all the fuel/vent/fill lines fed through, I need to trim down the tubes abit as they are abit long so to make them neater ill trim them abit, although this wont be done just yet.

I use a golf peg/tee, screw etc to cover the fill line and some models. On some I use proper purpose made pop in/out metal filling points. Some have valves on them to make it neater etc. You can also buy purpose made plastic pinch things.

Fuel filters, yeah one on your pump and one between tank pick up and carb is fine. Nothing will get in if you keep the lid on the fuel. I always have a filter next to the clunk on the fuel pick up line from my hand pump or electric pump.

Make sure there is lots and lots of foam sandwiched between fuel tank and sides of tank. To stop any movement at any angle.
Also the pipe in your fuel tank that wil be bent upwards, make sure it is pointing upwards.

Also the clunk inside the tank (fuel pick up line) make certain it cannot kink and is able to move around the inside of your tank unhindered. Very critical otherwise dead stick time as soon as you change pitch. If the clunk gets caught on anything within the tank.


As for your hinges whatever method you go for, think about putting cocktail sticks or small brass pins straight through the control surfaces and hinge and cyano them in and snip of to make neat.

Just makes your hinges 100% secure. Just in case!


One other thing just noticed on your photo, I may be wrong here but it looks like there is no glow plug in the engine? if that is the case, get one in and cover that hole. Any crap gets in there could be bad for the engine.

Have you got your spinner yet?

Something to start it with ?


Also do you know how much 'throw' the control surfaces need ?, what pitch prop for that engine?

I would also reccomend adding some exponential around neautral on your Tx as well, especially if you are starting new.

Ok to answer questions

1) I will use two filters

2) I will use foam dont worry :)

3) The carb line inside the tank is long enough to just sit above the base of the tank without actually touching the base, if you hold the tank upside down however the tube and clunk does not bend and go towards the top of the tank, this is impossible as not even gravity will make the tube bend back on itself, what I was told was, gravity will do its job and push the fuel to the back of the tank? the only way I could possibly get the tube inside the tank to move bend back on itself would be to make it shorter, which is not a good idea, it needs to be just above the base of the tank.

I have a glow plug, an OS number 8 glow plug which I purchased today, this will be fitted ASAP.

I havnt got a spinner no, was looking at either starting by hand or finding something else to use for the first start. Spent too much money atm so cant really get one for the time being. All the settings for the control throws are listen in the book, im going to be using reduced thows until I get used to it.

Pitch prop? and Exponential? can you explain abit more on these :)

Thanks

:)

Also here is a short video of my throttle control rod iv just installed, all the rest of the servos have been centered but are not connected to the reciever in this video so it may not look like they were centered, but they are.


Throttle at idle means carb open 1mm to allow start/idle, then full throttle = carb fully open.
 
DJMK4,
You're getting there slowly :) not long now!

Thought I would answer some of your question while i am around.

Magic`s advice is really good.

When you say you place the tank inverted, i pressume you mean, with the front of the tank pointing down? If so it is fine that the clunk doesnt bend round. Imagine if the plane was upside down, then the tank would be 'upside down' if the clunk is still towards the ground/floor then you are fine. some people leave the fuel tubing inside the tank too long, allowing the clunk to get stuck on the bottom . Hope this makes sense!

If you are going to start by hand, get a chicken stick, basically a stick with a piece of rubber on to protect the prop, that you use to flick the engine. I personally think its a great idea to learn how to hand start an engine, as you will learn a lot from it, and it is possible to damage an engine with an electric starter. (look up hydraulic lock!)

prop size and pitch.

for now, just get a few props that match Irvines recommendations. I think a prop size of 11x7 should be about right (APC are good props, but use an emery board to take the "edges" off as they are damn sharp!)


Exponential

It allows you to 'smooth' the controls around the center, allowing you to be smoother but still get the same amount of full throw.
What radio do you have?


BTW For now i would setup the throttle so that full down completely closes the carb, then use endpoint adjustment (if your radio has it) to adjust while you have the engine running. You the either want to set up a kill switch (again if your radio supports it) or make it so that full down trim on the throttle cuts the engine.

Any questions fire away mate :)
 
Was a no go im afraid because of specs of rain and some wiring issues. fueled up the ended up having to re-positon my regulator, the glow plug starter crocodile clip and the earth cable are so short I may have to extend (solder) them,

Had trouble getting the cables to reach properly.

Other than that I tested the fueling by the fill tube and defueling by the carb line and all worked fine.

Hopefully tomorrow will be a better day, im going to try to sort out some wiring issues
 
Looks like its gonna be great fun Daz, always wanted one or a coptor but i would ditch it in the ground most prob:)
 
Also:

Raptor 50 Helicopter (haven't got round to finishing it)
A Steam engine tug boat
Small scale hydro with a 3.5cc outboard
Submarine
Dave Marles 'Miami'

Understand all the RC gear u have apart from the submarine. How does that work then.

You cant use it in a lake cos the chances are you will not be able to see it in the water or know how deep etc etc. U know if it broke down underwater u might not be able to find it.

Or do u use it at the baths...lol when empty.....

i dunno just curious.
 
OK heres my problem. Iv managed to get the regulator earth cable through, that has enough length to allow the regulator to sit in the radio bay, but the red glow ignition wire (with croc clip) is way too short, so im going to extend it, either a soldering iron or a junction box, a junction box would be a lot easier for me

What type of wire should be ok for this?

I used to own so many RC planes, looking at this thread almost makes me want to go and get one and fly it.

As for extending the clip bit cut the wire and see what sort it is and go buy some similar, if you are worried about it being exact cut a small length and take it into a shop. I'd solder something like that rather than faff about with a junction box.
 
Only reason why I suggested a junction box is because I have no solering iron :p I dont want to spend more money :( im broke atm, holiday coming up soon....

Maybe a temporary solution = Junction box, permentent soltuon = Solder which I will do later on when im rich again, unless I can find someone with a soldering kit
 
I would solder that in the junction box, as the less joins the better.

haha you alright fella :) yeh it hopefully should be good. Aint seen you in ages! how you been?

Im good ta mate, Lived over here for a few years now. If your stuck i got an soldering iron, decent solder and shrink. Might have some cable too.
 
Cool glad your doing well :) I seen some pics of you at a LAN that my old boss used to run/help setup.

I think im just going to go down the junction box route for now as its easy to do, when I get hold of a soldering iron ill do a junction box/solder combo
 
Local swimming pools :)

Tell you what get a nice group of 20 something female swimmers, a POV camera/goggle setup and a submarine and you will be rocking :) no one would catch you sexual harrasment/perving if your in gym :D
 
Why are you using a regulator ?

Sorry I dont understand why you need one. I would ditch it completly.

Get a glow plug driver and start it that way.
