Raptor 50 Titan landed!

lol .. Bun doing crabbing thing already!
not too tight on the cable tie though.. reduce the transfer of vibration

Tried 95mm, rudder stops hard as a rock. The only problem I'm having now is when in forward flight and making right rudder, my tail will waver, just like Alan Szabo doing the crabbing thing Turning left during forward flight is ok.

Edmond got this problem before on his 90 size and he solved it by using cable tie over the gyro.

Am going to try this on my JrG770T. Hope it solves my problem too.

lol you should see my eyes popping out when my tail crabbing, something below shrunk and something almost coming out
Get to work liaoz... still got T500 to fix up also....

[HotDogBun]

Just flew 3 flights. Lowered gyro gain from 56% to 50%, the wagging still occurs but less frequently. Looks like gain might still be too high.

Now to solve another little issue. I can only do 6½ mins and left header tank full with about half min flight in main tank.
After the flight, I touched the bottom cover of engine, and about 3secs my fingers will find cover getting too hot to touch.
I am not using filter for carbuetta or whatever they spell it.
1.75 turns opened up for the needle.
Headspeed tagged at about 2100.

Is my flight time normal???

Flight time sounded too rich... but then not sure why it was that hot
whats your power setup again? and what kindof fuel?

I using 20% fuel.
RJX muffler with .50 OS Hyper.
Many also commented my flight time very short..

Er wait.. u touched the backplate while the engine still idling or totally cut off?

HDB,

Your engine is running too rich.

I touched it once I land my heli and stopped the blades.

HDB,

Your engine is running too rich

Yar, suspect so too. But if it's rich the cover plate should be cool to touch right??

[ammo]

To a certain extent, too rich will also increase engine temperature

[john_3330]

Bun, have u tried to move ur servo ball link to the inner most hole on the servo horn? It gives ur tail more resolution.. In layman terms, more 'zhun'..

[HotDogBun]

Its already at the hole nearest to the centre liaoz
Now I jsut worried about the flight time for being too short.

[ammo]

if the engine is too rich, it will be burbling even at high rpm, your tail will be affected in terms of kicking

[HotDogBun]

When I punch up the sound is quite sharp and pitchy but not burbing.
My tail not kicking when I punch up.
I am worried if I lean it any more the engine might get too hot and blow
