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

OK this engine has had a about 2-3 full tanks through it now, this video was taken just after turned the main needle (grey knob on the top of my engine) about 2 full turns from closed. (the fuel from the exhaust was before I turned it) Its now spurting a very very small amount of excess fuel when throttling up, but its mainly smoke when you throttle up now.




Still need to put a few more tanks through to brake it in properly, apparently it will then begin to go idle in a higher pitch engine tone and less vibrations.

At the moment, and I hope it stays this way, I can go from stick all the way down to full throttle without any coughs, splutters or anything.
 
Nope, I hit a brick wall with the build (not literally ;) ) as there were some issues with the bits it came with, the guy down the shop has replacements so I'm going to chuck him some money and he's going to tie up the loose ends and make sure it's ready to fly, get it balanced etc. I'm on the lookout for a small camera I can mount to it, I may need an anti- vibration solution aswel.

I did start her up on Saturday and stuck a tank through the engine :) can't wait to fly :)

I stuck a Hi8 video camera to my mates wots-wot and flew it around the fields a few times, was great to see all the buildings, plane was a bit of a handful though with all that weight on one side! :)

Sounds like a heavy cam if it was causing it to do that. The positing also. Better to try and mount it on the underside of the plane looking Down or half forward and half Down. Or you could put it backwards
 
My bro has one of those keyring cams, aslong as I can mount it ok and get the camera position right I'll order one :)
 
I found that cameras work best pointing down at about 20-30 degrees under the fuse :)

Oh, and if you are having issues with vibration, mount the cam in some foam. Should help dampen the forces a bit!

Also, have you balanced the prop? I can't remember if you mounted a spinner yet either, that could put it out if its off-centre, or damaged.
 
I havnt balanced anything yet :( purely because I dont know how to.

Im going to have to get a few bits sorted before I do all of this, as there a few control rod joins especially on the throttle linkage connecting to the servo as the nut threads have sheared because of the poor nuts that came with the model.

There is a few other poor quality bits aswel, the model shop has some replacement bits though.
 
Best way to balance it is by using the battery :) - Fit everything in place then move the battery up and down inside the fuselage until its balanced. On the instructions will tell you where the balancing point is :)

- prop balancing :)

Simples!

Thanks for the tips on balancing guys :)

Ill have to look in the manual to find the balance point inside the fuselage, also the prob balancing looks pretty simple :) is this seriously all you have to do? is this the preferred method?

Would there be anything I can do with regards to reducing the vibration? or will prop balancing reduce this?

No worries!!

Balancing the prop will reduce vibration a lot. Oh, and some people prefer to use paint, or tip-ex rather than tape, as tape can peel off at high RPM, or get damp and un-stick.

In regards to sorting the Center of mavity (aka C of G) of the model, thats even easier, you just need to move some stuff around so that when you hold your finger on the C of G the model balances.

The C of G is usually marked on the plans with a circular black and white quartered marking.
 
Sorry for the lack of updates on this :) havnt really been doing much on it as yet, anyway, few updates:


All the control linkages are now fitted and centered on the Servos :) (Rudder, Elevator, Throttle, and ailron servos, these control surfaces are full operational in terms of controlling)

Spektrum Radio had to be sent to Horizon Hobby as it developed a fault and I couldnt get in to the menus. They sent me a brand new radio transmitter free of charge with a 2 day return turnaround (winner) :)

I ripped out the Align 2-1 regulator and Li-po as this was taking up a lot of room and way too many wires involved, I have now replaced with a flight flat battery pack only and a small switch, and instead of using the crocodile clip and glow starter switch on the regulator, iv replaced it with a glow plug stick to stick in the engine when I need to fire it up.

Tonight I will be cutting away at the nose cover which will cover the engine and a few other bits.

I will post some more pics tonight and maybe some vids of all the control linkages working the surfaces
 
Nice one dude.

I really really must get round to taking photos of Dads planes and that, will sort this out for you :)
 
woot, always though the regulator was overkill on such a small model :D

Good luck! I might stick some pics up of my hanger tonight, will be working in the garage later, so seems like a good chance to get some decent pictures :)
