raptor 30 problem

[martin uly]

hi everyone had the raptor out in the back garden today , was hovering it on half stick ( throttle) ,when i went to increase the stick it coughed abit and cut out , after that it wouldnt start when i did eventually get it started i had to lift throttle stick up to quarter to get it to fire up . i left it a min to warm up and when i lifted throttle stick up it cut out again , any ideas anyone ???????

could be a bad glow plug , you can get them some times i had a brand new one that was no good ,would start the engine fine but as soon as i put the power on it would die ,other thing you could have a split fuel line some were
just a thought was the eninge really really hot when you landed ?

Had the same problem and put an extra washer on the glow plug and it sorted it

[martin uly]

i checked glow plug and seemed fine , fired up straight away when first went out with it , have checked fuel lines n ok , was hot as already had 1 hover out of it

i checked glow plug and seemed fine

Checked it or changed it.

Put a new plug in it and try again.

What engine is it ??.

[martin uly]

on the engine it says thunder tiger theres a 39 in a circle

Well I would do what these guys have told you to do, change the fuel lines and the glow plug.
I had this problem on my rappy with a TT39 in it, turns out it was running way way to lean, they are really not the easiest engines to tune .
I did get it running although running rich and leaning at the end of the flight, in the end I went out and got a OS 32 engine, worth every penny.

is it a new engine or a old one ?

[martin uly]

i have noticed alot of fluid up the exhaust side of canopy , have put a new glow plug in , am not that clued up on nitro engines im afraid as its my first nitro heli , so everything i try is very much a learning curve am afraid

I agree. But I would go for an OS37. 32s run quite hot an are not overly powerful. I ran a 37 from the box for 2 years and never touched it!

Having said that, the bearings are expensive. But I would still go for one every time.

i bought the heli off my mate second hand , he has flown it everywere , he sold it me so could get a 60 size raptor , ive fired it up several times now and it would always fire up straight away , nw it wont start up unless throttle is on quarter stick ( put starter in start spinning it up then move throttle stick up abit till it fires up) ,have changed glow plug and fuel lines so they ok ,today when i tried it after spooling it up i put throttle stick to min and it cut out
also when was spooling it up tilll light on skids i could see the blades bobbing up and down towards nose of heli ,would this be due to some wind that was on today ??????

[martin uly]
