Yeap, it is like that for 4G6/4G6S. I have been using the same rotor head set for a year and crashing it a lot. Usually I just try to bend it back and reduce the vibration as much as possible.
But unfortunately a recent crash has broken a part which is hard to repair so might as well just replace the whole rotor head. Anyhow, vibration still there but it is a huge different with the stability i am getting now. Just that the tail is still drifting only loh .... dun bother lah as long as I can fly.

Hehehe, any plan to let go your Trex 450 Pro or not?

no la ... the PRO i am keeping unless i decide to totally quit RC
if u interested in PRO got few fellas selling in MRC what .. hehehe

dont go for PRO lah....

go for sport if crash the tail boom bend still OK

if pro the torque tube bend oso... haha more higher cost!!!

when the belt inside worn out or bad condition but cannot see then crash even higher costs .. hehehehe
this is from a few ppl who owns belt driven trex450 .. suddenly just crash coz belt snaps or slips coz of bad condition ...
and both of them wanna convert to torque tube

After a while with my belt cp (which is belt driven too) I have to say I will try to avoid belt driven tail. One thing I hate most is the adjustment of the belt tension. Too loose not good but too tight also not good, there is no proper measurement you can tell whether it is the right tension or not ..... heheheh with torque tube then you don't have to worry.

But each has its pro and con lah, so it is up to your own preference. If you ask me to choose, I will go for torque tube now.

no idea... I got my 450 sport for RM300...

ohhhhh, RM300.

How old is that heli?
Everything working fine?

the last user just did 3D before he sell me... so yes the heli is in good condition...

Have you sold you 250SE ar? It has been removed from your signature

250 plan to keep... now barebone cause I transfer to 450 sport....

mainly 780 gyro...

The 450 sport was not completed with electronics when you got it?

nope... kit maaaa

Icic, no wonder lah. If with electronics I think he would not sell you for just RM300. That's really cheap unless the heli really has big big problem and hard to fix maybe. But for a kit, that's pretty OK for me.
So your barebone 250SE has only the motor and ESC on it now loh, right?

sport kit rm300 ... 2nd hand sommo ??
not a good deal laaa ... PRO kit BRAND NEW is rm450 or 500
considering the sport combo is 200 cheaper than the PRO

rm700 seems a reasonable price for a complete PRO

The 450 PRO is a complete heli with one battery. But the skid and canopy cracked a little bit, it looks like there was a big crash before. The owner said heli still good for 3D but he says only lah. Don't know I should trust or not, hopefully the electronics still working good.

Hehehehhe, negotiating for RM700 including shipping.

heli any part is replaceable laa ... so no big deal
hehehehe

No worries on parts laa Align parts plenty here

I understand parts are replaceable but if it is the electronics problem then slightly cost more to replace. End up with about the same price for getting a brand new PRO already.

then buy new one lorr ... 2nd hand stuff hard to say one .. hahahaha
or u buy kit and put in the electronics yourself laaa

well... there is 2 options...

you trust that guy to be pure holyness with what he/she say then go ahead..and take the risk... dont cry when there is electronic issue

or

1. Get a KIT (450/250) assemble it... get the electronic one by one or look for second hand...

2. Get Combo Pack (450/250) which have everything except TX/RX & BAT

3. GET a brand new RTF package from hobby shop
