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

Elevator 3/8" each way,
rudder 1" each way,
ailerons about 3/16" each way should keep you fairly safe.

Prop 10x6 to start with would be a good size.

C of G - The Wot4 is perfectly conventional. About 3" from LE (leading edge) for first flights. (balance with a empty fuel tank)

You might be surprised how responsive it is even with those quite small control movements.
 
Cool ta for the advice :)

OK managed to get all subtrims down to 0 apart from the rudder which I have on 50 as I have tried but I cant get it done by the metal clevis, which may I add is a pain in the back side think I broke it, may have to buy a new one.

So yeah, all done apart from rudder which is at 50

Can you put a 'Z' bend in the wire rod from rudder to servo, would that allow you to get it down more ?
 
I guess I will have another try at the rudder yes.

Lead acid battery turned up today. Hopefully tomorrow I'll have my 12v starter and a new spinner, going to fire it up
 
OK, bits arrived so I thought I would start it up, SOO much easier!!

Please forgive me for the video rotation, I dont know why it done this.

Please note that I was running engine with wings off however I wanted to see what it was like with it on so I put them on (ignore the floppyness as I did not tighten them right up.

I had a problem later on though, went to start it and it it looks like messed up the thread on the actual prop where the prop shaft goes through as now the prop spins freely and wont "screw" if you get what I mean?

Is this something that happens often?

 
Right, regarding the prop. Trying to understand what you are saying.

The prop will screw onto the shaft then on most engine shafts will screw on past the actual thread. you dont actually screw the prop on. The prop goes on the shaft, yes you can screw it on all the way then it is secured with a washer and nut.

Put the prop on and whilst looking at the front of the engine, with spinner, nut and washer on. The prop wants to be turned against the compression point of the enginer, ie: turn the engine clockwise till you feel the start of compression and then fix prop on tight.


Hope this makes sense, bit long winded, but hopefully you get the idea. Quite often we buys props and the hole in the prop is too small to go on the engine shaft so we use either a prop reamer. http://alshobbies.com/shop/search.php?Desc=AlsZone+Prop+Reamer
or drill and drill bit to get it to correct size. So it is nice and tight along the shaft.

Video looks ok. Make sure model is secured at the tail plane, just in case it lurches towards you when you start it ever.

Cant tell from the video if it is running rich or lean, when you start it, get a friend to hold the transmitter and point the nose of the model sky wards when engine warm to see if engine leans out.

Needle want to be 1.5 turns from full close is a nice starting point.

Apologies for what seems like a Mammoth thread revival but how are you progressing with your aircraft - have you had a chance to fly it yet?

I am seriously tempted with one of these as a 2nd aircraft - first trainer hasn't left the deck yet - but will soon. Plenty of engine run in's and scrutineering by local flying club chairman. Not been to a club yet or nor do I intend to, to start with - no time unfortunately. <dons tin hat> Have been flying a Mugi Evo (coroplast) and Aero Bird Extreme for 18months on and off to keep my eye in sts.

Happy to start a build thread if I purchase one :)
 
Just broke out one of the slope soarers for a quick air-worthyness check, seeing as the weather was so nice :D First flight for a LONG time!!

Only hand launched from a small hill overlooking my house after a quick range check. I had re-charged the nicads earlier in the week after seeing the weather forcast! Decided to lob my cheap ebay camera on the thing without much thought over positioning. After watching the resulting video, it seemed to be pointing a bit high. I think next time when I go flying proper, I will mount it a bit better :)

I think it needs a bit of a re-trim, and it also turns out I had not fitted my wings up quite perfectly, as it was flying slightly off-centre, and moving right a bit.

 
I really need to get my model sorted :(

I need a few spare parts, new prop, and I may need to replace my closed loop system with a control snake set-up.

^^I remember having one of those wooden frame, rubber band powered kit planes as a kid. Spent weeks building it with my dad and on the first flight it hit a tree, crashed and burned (well not literally on fire) and it was un repairable due to the way the kits were made.

Pesky trees.
 
O well, at least you didnt spend too long making it...........................................................................


but really, unlucky man, hope it's not beyond repair. GL
