when i drop the heli using throttle hold from a couple of feet up ...
no yaw at all .. HH on the gp750 is solid head on .. hehehe

Have not tried this on the 450 Pro yet .... heheheh sorry for not telling earlier, it was the 4G6 I was talking about .....

Should be something to do with this little heli as I cant find this situation on the other bigger heli as well .....

my cheapo WALKERA radio do not have throttle hold one laaa
so cannot drop heli without crashing .. hahahaha

Yoooo Yoooo, tomolo is another inverting day!!!

another FPV day for me ...
this morning was good ... fly fly then suddenly locked out for 2-3 seconds
W T F ?????
i was about 300+m out only ... lucky as plane was dropping i got back signal and managed to bring that thing back home safely
i had previously flown to around or over 700m without any probs ... i will have to do something about rc range

but the image on my NEW GOGGLES is very very good ... much better than my old one ... but of coz the price oso much much better laa .. hahahahahaa
now running wireless goggles with head tracker ... powered from radio so only 1 wire on me and i can walk around too .. hehehe

Too bad i am not living near to u or else i will go and feel ur fpv poison already .... Hehehe

Hehehe, main gear, main shaft, flybar and main blade have to replace. But it looks like the feathering shaft survive loh .... using a screw driver and turn it but can't seem to see something on the blade grip.

i will prolly be getting a new set which is more powerful for my FPV
so will sell off my OLD SET CHEAP when i decide to do that

heli crashes are unpredictable one laaa .. so parts damage count oso unpredictable ... thing i hate with heli is .. after u fix everything u can SEE DAMAGED and u go fly it and something else comes up .. hahahaha

Dammit... my rotor head screw snapped... rotor fly out... crash!!!

Damage...
1: 1pc hex screw
2: 1 hex bolt/nut
3: Align T head for 450 sport

That's my worry, it was actually crashing down during inverting. A bit surprise when the feathering shaft is still good.
But still I think I wont replace this until I found something on it. Hehehe, removing the feathering shaft should be simpler comparing to changing my main shaft bearing.

That one cannot be over tighten. Just nicely lock the bolt and threadlock will be fine.

Qiw sell me la ur fpv

repairing crashes should be a NORM already for RC flyers
i repair and fix and assemble planes quite often .. hahahahaa

mr shock .. my CHEAPO FPV setup may not meet up to your expectations laaa .. worry u complain .. hehehehe

Qiw, is that normal that the tail yaw to left slower and yaw to right faster because of the main rotor torque?

I can feel that right piro is faster or did I have something wrong in the setup?

if your piro rates are slightly different ... adjust your end points
if u have equal travel on both directions and tail blade has no or very little countering pitch when servo is centered then for sure one direction piro will always be faster than the other due to main rotor torque
adjust using your dual rate for rudder .. leave the end point adjustment on the gyro and travel adjust alone

Added on May 30, 2011, 10:28 pmor if u do not wanna touch the radio setup then do this preferable method (i did it this way) ...
then u have to do the rate mode style rudder setup like for the older gy401

put your gyro into rate mode (gain is same % as your head hold) instead of head hold ... then try and hover your heli
u will find the heli tail wanna swing to the right ie. no countering torque
adjust the linkage to provide more pitch to counter the tail going right ... normally is until about 8 degree pitch (almost impossible to gauge by eye unless u expert) ...
when u can hover the heli in rate mode relatively stable without the tail drifting too much (damm hard to get perfect no drift) and no rudder input correction ... then u are done and no need to adjust radio or any other electronics
put your gyro back into head hold mode ... test your piro and u will see that left and right piro rates will be the same

Qiw, can la for a start.. Decent quality ok, if i have more interest then ill invest on better one

the stuff i am letting go is

200mW 900mhz vtx with stock antenna + cloverleaf CP modded antenna
900mhz vrx with stock antenna + skew planar wheel CP modded antenna
this GOGGLES ... but i have added blinders at the side and top to block out sunlight when outdoors with hot glue ... oso the right side ear support broke due to over enthusiastic to wear it one morning but repaired with hot glue nice nice oso
basic 420tvl camera with 3.6mm lens ( changed to this lens .. glass type and very clear) stock lens is prolly 16mm or so and plastic lens .. not usable for FPV unless u wanna crash .. hehehehe
i have oso made a mount for the camera so u can just bolt it onto your plane with 2 screw or to a servo horn and servo to use for panning (i dont use tilt).

this system i have tested to horizontal distance 800m (checked distance on google map) with perfect video
so LOS prolly 900m or more ...
all connecting cables included ..

u will need a 3S to power the vrx and a 3S to power the vtx (u can splice power from your main flight battery for vtx if u dont wanna use separate 3S)
thats all u need to fly ... plane and rc controller all not included of coz .. hahaahahahahahahaaa

Let me try to understand what you were saying.

Well. The length of the tail shaft will always be fixed, so it gives you the absolute value of pitch all the time. For example, 20 degrees with +10/-10 or +13/-7 or +15/-5. Just assumption!

If we do that in rate mode then at servo horn centered, then it should be around 8 degrees (counter torque). But then although servo horn is centered and now your tail pitch slider not center already. From there isn't it the tail pitch will still be only +10/-10 and it just that your center the servo horn (not tail pitch slider) with +8 and maybe you have another +2 to counter the torque only. In this situation will it still giving the same piro speed on both direction?

The 450 Pro has a fixed position to install the servo so is that possible to achieve uneven tail pitch? Like +13/-7 or +15/-5

yes ... center the servo ... adjust the linkage only
forgot .. after that u need to set the end points on the gyro again

your tail pitch is not supposed to be even for both sides at maximum travel .. unless u do not need counter torque la

if u still not happy ... then do the flip the tail grip mod like finless bob did ( i oso did that la ) .. give slightly more travel for the counter torque side

done the above and i have found my piro rates on both sides are approximately the same ..

tail pitch slider is not an indication of anything except that if it is centered then u get equal travel on both sides which is not what we want for countering the torque .. in hover position u will need some counter torque ... thats why slider is not at center when your rudder is in neutral position ... that is the nature of this PRO ... v2 may be slightly different coz it seems to have some counter torque when slider is at center

another mod that i did was to lengthen the tail shaft to give more counter torque ... hehehehe

Wah qiw, thats some complicated stuff man...izzit pnp? Im using pheonix 2000 glider anyway...

all u have to do is ....
fix the camera onto plane
fix vtx and antenna onto plane
provide a power source for the vtx and camera ... 3S lipo is fine
the cables are provided

then u need to plug in the goggles to the vrx ... charge the goggles batt (USB charge cable porvided along with A/C adapter) b4 use
provide power to the vrx ... 3S lipo here is oso fine

then all u have to do is NOT CRASH ... hahahahaaa

YES ... everything plug and play ... but u will still need to mount the camera and antenna laa

macam mana mahu bikin this mod?

Slapshock, still playing heli?
