Last week I became the proud owner of Raptor Titan 50. Granted it was second hand, but the condition was immaculate, very clean and according to the first owner never been crashed.

This is my first nitro heli after progressing from Hummingbird, Hornet, Belt CP, Trex 450, Lama v3 in that order. I still have the Trex and the Lama for when i just gotta "go".

I was surprised at the size of the Titan - I knew it was big, but gee - my trex can be swallowed whole by this beast.

Took me a couple of days just trying to figure out how to put fuel in the damned thing. The tank didn't have "filler hole" - wtf! ok, so i finally learned after exhaustive investigative work that you use the silicone tube that connects the header tank to the carb.

Bit of divided opinion too about the use of air-filters: some do some don't as they say it may mess with cooling problems.

The pitch settings was quite easy to setup. The built-in pitch gauge helped tremendously. I wish all helis had this feature. Tomorrow I'll setup the throttle curves and I expect to maiden this weekend.

will post some pics here very soon. Wish me luck.

PS...the guy i bought it from said it was flows regularly for 18 months, sold it because it wasn't his everyday model. What can I expect to replace without waiting for it to break?

cheers.

Congrats bro! I too got my first nitro (Raptor 50 as well) last month. I've put 8 tanks of fuel through it so far and LOVE it!

Good luck!

No air filter.

The built in pitch gauge is useless, get a pitch gauge so you know whats really going on. Unless the linkages are set up so that its accurate, which in most cases they arent.

http://www.raptortechnique.com will be helpful.

The first thing you want to check is the tail rotor hub. If you can see set screws holding the hub to the tail rotor output shaft then you have the upgraded hub. If there's no set screws it uses a grub screw that goes through the bearings and hub and holds it to the shaft, replace it immediately with PV0499.

Im glad i read this topic. I too have the Raptor Titan and after reading what you wrote i went and took a look at my setup and sure enough i need to get that upgrade. Even though I've been flying it for a while now and never had any problems with my tail its very much better to be SAFE than SORRY...

What does SUS stand for???

Fuel spitting out of the muffler.

SUS = Stainless steel. The part for it is PV0499 (stainless steel tail hub). I ordered mine yesterday so hopefully it arrives very soon.

BTW, I started the engine last night. I must say idled it quite smoothly. Spooled her up to the point where the skids became somewhat light but because the throttle & pitch curves have yet to be properly set, that's as far as i went.

One thing that worries me is the amount of pink liquid that was spitting out of the muffler at a 2 minute idle. When i tipped the heli over, it started pouring out - about a handlful of thickish pink jelly like substance which i am assuming is fuel (but why so thick?) All up about 50ml of the liquid came out. IS THIS NORMAL?

Its running rich and probably had some accumulated oil in the muffler. Way rich.

Pls Help me troubleshoot my engine.

Hi guys. As recommended by the Raptor users here, I've finished upgrading the stock tail hub with the new SUS PV0499 part. So far so good...

The next problem i encountered was the fuel really spitting out of the muffler even at idle. AFter stopping the engine, i can tip the heli over and this thick gooey pink (same colour as my fuel) liquid pours out. Please check my 27-second video and tell me what you think:

Below is the photo as well.

As suggested here, perhaps I am running it too rich but I thought the video may explain it further. All comments/thoughts appreciated.
