Sebart Mini Avanti w/ K45 build thread
#952
I just got mine all together after purchasing it used and going through it
Basic empty weight with the CM 1.3L tank is 8.8lb, not adjusted for CG correction although I can shift my ecu pack
Does anyone have the Xicoy CG measurements to verify against hasty eyeball measures? I can't find the thread here that I think Fenderbean started
I measured 450mm between the nose to mains, 25mm between mains and CG mark @145

As awesome as that drawing is, I was referring to the xicoy CG scales
Disregard I found it but there were no measures on it.

Low tech is good! Its how I balance the big boys. But if I'm gonna weigh her, I'm gonna exercise the scales anyhow.
my wings are a pain to remove now so it's too late for the hanging fixture. I used a dab of e6000 on the leading edge root/fuse joint. I do not love how flexy this thing is. no wonder the manual says be careful about blowing the fuse apart.
Hey what is the thread on the canopy screw, mine escaped!

Roadblock ahead: Kingtech.
Using the GSU to 'look' into the ECU, with 2S lipo powering the RX and the ECU I have no feedback from the motor or see any changes to throttle position.
When powered by a lower voltage pack, the 2s life for example, the screen flickers constantly, feedback is limited, throttle position shows changes, but I still can not get into the motor.
Waiting to hear back from Barry but it seems the maiden won't be tomorrow as planned

I'm not sure the issue is the same but.....I had a problem with the "Wait Conn" error as well. The fix was actually in the cable to the turbine. I took it out on the turbine side and reseated the plug and everything was fine. While everything appeared tight and connected properly, apparently it wasn't happy with the connection. Doing this cleared up my errors. At least it's something simple to try. I can't imagine it's the 2S pack as that's how mine is powered as well.

I'm sure you're not asking me but, just in case, I have the 3S LiFe powering the ECU/Turbine and 2S running to the avionics. You bring up a good point, however, to make sure you have the 3S LiFe for the ECU as it's own supply.
#961
I've been through the cables, of which on this generation of turbine there are fewer than previous ones. It still could be this, but I do not have any other G3 cables to swap and try.
I do have the KT 3s Life pack to power the turbine, that drives the starter, unrelated to the operation of the ECU or GSU.
I've just tried a new setup separate from what I have in the model. a DX18, with a simple 6ch dsmx rx, the problem is consistent in the presence of the 2s lipo, and intermittent under 2s life. guess this one goes back

These G3's are new territory for me with fewer connections and wires, but the G1 and G2 the 9.9 pack was only for running the pump and starter motor. Everything else, including the ECU (and a GSU if present), was powered bye the bus voltage on the throttle port, wasn't it?
Thats why when learning the RC signal on a kingtech, you unplug the 3S or your motor would spool during stick up setpoint

that's interesting different than any setup I;ve ever run or seen before. So just for the sake of asking, do YOU split your 3S life 9.9 Turbine pack into your ECU on a JR/servo 3 pin plug" and also the Deans plug into the ECU? ie...you don't supply any RX power to your Kingtech pieces.

Yes, the 3S LiFe powers anything KingTech. The 2S powers avionics (RX/Servos). Maybe this will help:

My apologies. Maybe I'm not following what you're saying. The 2S is regulated to 7.2V and plugs into the RX. The ECU plugs into the RX via throttle channel. The GSU, turbine, and pump plug into the ECU along with the LiFe. I'm not saying what the 3S powers exactly as I actually thought it was the ECU, starter, and fuel pump and probably the GSU but, as the GSU turns on with RX power, I think I'm incorrect about that. I noticed on your video on the GSU, your Vr was 0.0 so nothing is coming from the RX at that point. I don't know if that's it or not. It sort of makes sense if the ECU doesn't sense the RX that you get the Wait Conn error though to me. Again, I'm no expert.

One my DX18/6ch setup I was able to get it to work 1 time, and even then it was incomplete with the readout info. On the very next power cycle, the communications failed. Nothing got unplugged, just a power cycle. This occurred on the 6.6V supply. at 7.4V it just flat out refuses to do anything besides stare back at me at 100%.
Its a dead horse at this point. Something internal, not related to my setup.

Maybe the G3 ECU is 'smart' hope so, that would be cool. But this is from the G1/G2 manual and is how I remember it being.
Also- my problem is solved. took the ECU apart to find the magic smoke had gotten out through a hole in the PCB.

Hello again, new and definitive brackets for Mini AvantiS 1.3L tank. Now the back bracket grip the plywood and make more easy the installation and fit the tank 2cm back.
Special thanks to Valerio Lorenzini for the idea.
I hope you like too.
thanks

Hello AvantiS lovers, like you know, the new version of MiniAvantiS tanks is in full production, there are tanks in stock for send immediately to the customers.
You only need choose barb or Fest fittings. All barb tanks will be served with 90 degrees vent and normally in Festo fittings too.
The combination with my UAT 100ml available for both versions.
Best Regards from Spain.

Hi guys. Great information. I have my jet ordered as was debating weather to go electric or turbine..... I now have my king-tech g45g3. Has any one used the jp 60mm wheels and breaks? just trying to see what size i can make fit with out modding the fuselage. Thanks for any help in advance
