Hi Guys, I think I now have my helibug sorted. Still has a shake on the tail occasionally but your comments would be welcome.

Many thanks to Mr G.

Now needs a new clutch liner due to hot start today.

Had to fly a horrible messy niyro instead!!! LOL

In my opinion it needs to be a tab lean other than that it flying awesome lots of power.

Leaning the motor a bit should take care of the tail kick too. This is my observation.

Hope this help!!!

Thanks for the tip.
I was hoping for more feedback.
That was the first time any video has been taken of my flying and I was nervous with my fingers shaking as I flew. It was not my best flight but does show my "style" of simple open aerobatics and not 3D.
I like the stability of the gasser and find that the need to manage the collective helps the learning process.
The next step is to fit my fbl head and beast x that I have had waiting for when I am satisfied with the set up and reliability.
I will start to lean it out a little and see if it improves before I take the plunge and go flybarless.
Again thanks for the comment, any more would be appreciated. Keith

Ally42.

When you start leaning the engine do it little by little and on both needles. Once you hear a nice tone check temp and after flying check your spark plug. Remember the spark have to be brown dark not light too light means to lean too chocolate means to rich. Use your video as reference for the tone once you get the engine tune properly you will see what I mean about tune and sound. It will come to you.

Once you switch to FBL you will realize your Heli is a different animal trust me!! The beastx is a good unit ease to set ease to use. There is plenty of info here on setting on different machine including yours.

Is your engine modified or is it stock? Are you using regular pump gas or Colman fuel?

Shihan,

The exhaust is a century v4. It has the restrictor removed.
I had lots of trouble with the v3 leaking and cracking but the v4 is superb.

the riddick.

Hi, the motor is a trm vx270. I got it from Al recently but had a little wait as he was having back problems.
It is the first "proper" helicopter tuned motor I have had and I am very very impressed with it.
I previously had an Oneill bros "full tune" stroked and ported unit with a stuffed crank. It did vibrate quite a bit and I don't think it ever acheived its potential as I am sure it was meant for a buggy, and to rev far in excess of the 11000 rpm I was using. There was always a mini tsunami in the tank with the OBR and it always spotted the heli with unburnt oil. Its demise was due to my reducing the oil ratio to 100 to 1, and not sufficiently richening the mixture to compensate. I now use amsoil sabre professional (having found a UK supplier) currently at 60 to 1 with pump gas.
The OBR picked up on the piston and liner around the exhaust port (as usual) and the expense and trouble in getting a replacement due to the 2mm stroker crank, made me choose a full replacement from Toxic.
Best decision I have made recently, and I would recommend TRM to all.

Thanks for your input, I will be real careful as I set the mixture.
I am looking forward to the beast x fitting, but don't know if I should update the firmware to v3. My other two beastx's are version 2 and I like them on my trex 450 sport and trex 600 nitro.
The recession means funds are really tight now and I still need some 690fbl blades for the helibug. I always used to like radix blades, but to save money I have been using align 690d's for a while and must admit they are fine.

Thats all for now. I will post my results when I get it sorted flybarrless. Cheers Keith
