I'm building mine now. Everything good so far except that the servo arm hits the bolt for the servo mount. I can't find m2.6 screws anywhere. I'm using hs85mg, gy401 & s9254, Hyper H3025-10, Hyper 80amp sbec esc. I got the steel landing gear and raised the rear have 68mm tr blades coming also, and an AR6200. Helidirect now has a manual it helps with the links

I allready have the carbon 68mm rear blades ! i need to make any mod on the vertical fin to use the carbon blades? haaa Im going to use hitec heavy duty red horns on the servos ! the same bob use in the t-rex 600

P.S. sorry for my bad english

[TN-REX]

I put a spacer on the back of the landing gear and it raised the tail A LOT. I could use 85mm TR blades now. I did this to my T-REX to keep the tail out of the grass awhile back and it works great.

I finished my 3dx500 just these days and made some hovering flights. The tail is drifting counter clockwise with the GY-401 and S9254. Maybe to less headspped with my 3s-Setup (4400mah), but it moves to both sides by command pretty well. I ordered 68mm tail blades, maybe this solves the issue. And I will use a higher landing gear or lift the tail by putting a spacer in.

My cyclic servos hit a screw of the frame, so I simply made the screw flat. Now it works perfectly.

But I did not even dream the difference to a 450-Heli would be so big. I think I found my new heli number one. :D

[canizes]

If I change the blades for the ones Helidirect sells (68mm carbon) will they hit the ground ???
the vertical fin will be short?

Let me know

Thanks

[hung]

so is mine

should go get it by monday :D

I got the HDX ( ie trex style head )

[John Heli]

The fin is already very short with the original blades so mine have scrateches. With the 68mm-blades you definitely should have a longer fin.

[canizes]

Where i get the long fin ? the only one i see is on the helidirect but is soldout ! thanks Nuno from portugal

[John Heli]

I have no idea. I am facing the same problem. Here (http://www.helifreak.com/download.php?id=27058) you can see a work around: Lifting the back landing skid and extending the fin.

[petmen]

i made the tail fin my self.

[John Heli]

How did you make it? Which material did you use? Do you have a picture? And are you selling them? :wink: Sorry for so many questions.

Very nice fotos !!! this skids are more tall? im going to buy one from heli direct! hehehehehhe

Nuno from portugal

[John Heli]

Really nice Pictures. I ordered skids like yours and hope they arrive soon. What engines and speed controller are you using?

[TN-REX]

HP 3025-10 and HP 80amp ESC with SBEC. I only have 3s batts now so I'll run a 26t pinion when funds allow I'll get some FMA 4s packs and go with a 23t. I moved the top tray to the bottom and put the AR6200 on it the second reciever mounts perfect on the rear servo with a little cutting for the antenea. I put some spacers on the rear skids and it lifted the tail a lot.

[canizes]

lets see some videos of this !!! on the air!!!

[XVortex]

Hi guys.
Is the S9650 servo fits Ok to HDX/3DX frame or it requires some modifications ?
Can you post some tail servo photos ?

Thanks.

[John Heli]

I can give you a picture of a S9254, which fits perfectly.

[TN-REX]

Getting Close now. I have my servo arms (metal) and Lepton servo mounts installed, Gyro and servo installed. Need to finish the head (pitch +10/-10 cyclic 6/6). And dial out CCPM interaction.

[cyanide1973]

Just wondering has anyone tried to use 2 3cell 2200mha batt. Also I just ordered 2 air thunder batterys 3cell 2200mha they are 30 x 37 x 113mm (bigger then most) and the battery tray on the hdx500 is 140x51x39mm is there any way of fitting them in.

[John Heli]

Yes, I do in my 3dx500. Mine are not fitting, too.
