Hello J10’ers
​​​​​​ I’m making slow but steady progress on my J10. So far no major issues ( other than a few missing plywood parts).
There are a few J10’s at our field and the owners state that their gear mounts had to be reinforced. (I’m assuming they meant the mains). Looking at mine, it is constructed of a 5+ ply plywood and then carbon laminated. It’s blind nuts are attached in the usual manner. I can’t imagine this easily failing. I noticed the nose gear laminate is only a 3 ply sandwich.
Sooooo....the question is....do I need to apply another layer of carbon? Thoughts please.
TIA

I never had the need to reinforce any of my other Jets landing gear plates....they seem pretty sturdy to me.....so I’m not going too in this one, I will however laminate a 2” carbon Strip on all the seams....I received the rod’s un-damage from Ray, but they are too short, must had different Vector servo’s location.....should have all my order this week....I want to finished doing the mockup of some stuff....then I need to paint this ;)

Thanks for the reply. I just checked my vector rods ( which are 2 pieces) for a total length of 59”. All is good. This probably doesn’t help but my servo cutout starts at 3”. I also noted my J10 was manufactured Dec 2018.😳.

I got 3 set of rods to make these one of these set is 2m long LOL 😂 ...something should fit ;)

I think mine was older :( I wasn’t told about the fact that it was an older kit.....

That had been order from another fellow from Dubai...not sure what happen to him....anyway I was asking for a white one......It was almost a complete kit, in the end it doesn’t matter just a pain to source the intended size....

I assume you got the Electron set? Did your gear bolt in fine?

rbtgold 09-13-2020 04:26 PM

Don’t feel bad, I wasn’t told my Display scheme was an older kit! If I would of known that I would of gone with the current Splinter scheme.
I test fit the Electron / Carbon main gear set and yes, the bolt pattern matches up,...... no additional screwing around.
Vector rods are next on the to do list.

‘Mine was fit for the previous retract offering :)

I don’t feel bad...... 😬

OOOOPS, , I spoke too soon! The Electron mains bolt up but the nose gear does not. From viewing a friends J10, his is the same. Well, 2 new holes and possibly elongating the Electrons front holes should take care of it. In the meantime onto the Vector details.
Rbt over and out!

Hello J10’ers
​​​​​​ I am about to mount my KT210 and have a quick question. The manual does not state an incidence angle. Should the motor be parallel to the wings root ... or??? Thoughts please.
TIA

just rotate 45 degree the motor in the engine mount so the Word Kingtech toward the top of the fuselage......in other word upright when the plane is on its landing gear....

Assume you mean thrust angle; The turbine body needs to be perpendicular (90 degrees) to the rear fuselage / tail cone interface.

Dansy 09-28-2020 08:14 AM

Ah incidence ok make sense that would zero incidence Center into the vector....up/down and sideways

rbtgold 09-28-2020 09:27 AM

Yes....Thrust angle! Thank you both for the info.

Do the Canards remove easily?

Theres 2 bolts on the underside for each....sort of easy, I intend to leave mine on after painting...

Can someone share the setting value for cortex Pro?

‘I have installed a Cortex Pro..interested in the setup as well......winter is here ;)

Bobneal1 12-02-2020 07:52 AM

Go to the CARF website and download the Mephisto manual. They have settings for the gyro in the back, (cortex pro) and start with those settings. I am flying mine with those settings and they are ballpark ok for me.



Dansy 12-02-2020 08:13 AM

You mean for the iGyro3e......??

Bobneal1 12-02-2020 08:17 AM

Gyro settings
 
No,

I mean the Cortex Pro. Look at the MEPHISTO manual, not the J10 manual . I used the vector nozzle settings from the Mephisto manual .

Ah I see ok I will have a look, thanks

Dansy 12-12-2020 12:04 PM

Well I’m pretty much done, minus gluing the battery’s tray and canopy (after painting) I put it on the scale all assemble and I’m about 12kg with the uat simulated full...(lead) pretty happy with that....so I took it apart and will start getting the parts ready for paint...with no joint lines anywhere....so that will take a while LOL 😂

Nice; hope maiden goes well.

The J-10 has such a beautiful / sensuous shape. Art in motion - and they fly extremely well especially in hi-alpha. Going though a bit of withdrawal at the moment not being able to get out and fly mine...

I am confusing about the Memphisto setup value for cortex pro.The manual showed that there are 3 banks(Cortex has only 2 banks) and no need heading mode for 3D flight.
Is it correct or not?Most pilots always suggest that the heading mode need to be used in 3D mode.
