Hi to all, my pilotrc j10 arrived, will start the building soon. Kingtech k210 g2 ,powerbox mercury, jr dfa 8911 and 8477 servos etc my equipment then need the picture of the inside of the fuselage, where do you locate the fuel pump etc? can someone take the inside of the fuselage which all equip. installed??
any recommendation before I start bulding such as week joints places etc.

As you can see in the pics, keep your equipment as far forward as possible. All the batteries are fastened to the removable wood tray….UAT is forward of the suggested location in the manual.

The bag of sand was just to keep the jet from tipping off the stand while I was working on it....lol

butta

Thks for the fuselage pictures, helped a lot

drorso

It seems as the fuel pump is about 2 meters from the turbine. Isn't it a problem?

GULDUKAT

I have built 8 of these so far using the K210 and the Swiwin 220. No issues!

Even the appx 2M engine cable had no issues with current.

drorso

That's good to know. I'm building an Ace Composite J-10, and wasn't sure where to place the UAT and fuel pump. I'm going to install a Merlin 210.

Thanks!

butta

The power cable should be extended , because distance between the K210 to front about 2 meters. So how you solved this matter. System does not let me upload picture otherwise I could add the picture about the short cable matter

GULDUKAT

on the J10's with K210 G2's - the ECU was close to the fuel tank (middle of the fuselage). On the J10's with Swiwin 220's - a 105" cable was made using 16AWG wire and MR30's and the ECU was on the equipment tray.

butta

thks for the reply, will setup the ECU as you mentioned midd fuselage just infront of the fuel tank.

butta

but in this case I think I should add more weight infront of the fuselage to the battery tray, will be 2 ea 3.300 mah lipo , 1 ea 3.800 mah lifepo4 ecu battery, 1 ea 3.000 mah landing gear battery

butta

I just want to know that you all using stock uat tank?? I seems very very weak, just one brass tube with opened end??? Look like pilotrc says do it whatever you want please inform
thks

flyloose

Well it works fine for me….I haven’t had any issues with air bubbles so not sure what more to tell you

butta

I am using kingtech k210 g2 and if any mini air bubble occurs then 210 N can suck easily from that open end brass tube.

GULDUKAT

I have over 20 of these UAT's from Pilotrc - all 250ml - but I do make a small mod. I replace the brass tube with a 4MMID felt clunk from Tillotson:

https://www.lawnmowerpartstore.com/f...-ow802-ow-802/

I bought these a few years back for my prop planes and jets (it is the same one that comes stock with the CARF mephisto). I drill the hole to 4MM (some of the older clunks were 2.5MM but the housing has room for 4MM ID).

I had 2 flameout when using it on my TOPRC Voyager on a very high aerobatics flight - with the K260. Autorestart fixed the flameout - landed and saw that I had maybe 40ML or so of air in UAT - (which is not much.)
On the next flight - I added the felt clunk and ever since no issues. (still have as high as 60-70ml of air - but no flameouts)

butta

So; first time on the ground at home, can someone tell me the something about the landin gears angles?? are they right? I even can not let go on the ground by hitting hand. should I loosen the small screw on the LG and adjust the angle??

GULDUKAT

Yes

flyloose

And lock tight all the screws as well

butta

Is there an easy way to check the CG. How you check the CG 320mm from the front leading edge on the root of wing but how you check? Fuselage is not hard enough to check from underneath ........

GULDUKAT

I followed PilotRC's guidance and they asked me to ensure that the nose wheel weight was 1.1-1.2kg. After trial and error - I am now at 700g.

Hi DesertFox,
we met in GA jets last year, "the Miami guys"
i am setting up my pilot j10, its my first canard/vector 3d plane.
need some assistance!
Can you help?
Pls whatsapp me to 305 205 7171
thanks

Hi to all,
I will have the maiden soon, checked the cg is 310mm.should be OK but one question before the first flight; do you use VT on take off and during the flight and landing ? or Take off without the VT by normal throws just elevator and canards?

flyloose

I generally take off and land with TV OFF….just my personal preference…my suggestion would be to take off with the TV off for the maiden and then you can go from there….I know others like to leave the TV on for the entire flight…I tend to alternate between the modes as I have a 3 position stick end switch on my transmitter….so it makes switching very easy for me….also just a friendly reminder to leave the gyro off till you’ve at least got the jet trimmed out….personally I rarely try gyro during a maiden but that’s just me
