Hi all,

Just in the process of putting a IBU2 Base into my T-90 and the board recycles when I fired. I thought maybe it was the battery, the receiver and possibly the IBU.ini set-up but replacing all of them with known working ones and the problem persists. I even swap in a known working IBU2 Base with its own SD card config and it is still doing the same, so I am pretty sure it is not the board. Something about the new tank is causing the IBU to recycles and I am just wondering if anyone has any idea what that might be ?

It has 480 motors installed. Could that be it ? I am also using the new Heng Long speaker (alloy cone, but circular not like the Taigen ones) and it is making the correct sound so that can't be it. Nothing else is plug in.

Something was kinda strange also when I plug in the recoil servo, the board didn't cycle it like my other IBUs on start up. Don't know if this is related.

Puzzled.

Sounds like a "brown out"...used to have them on my dbc's..are you using nihm or Lipo batteries?

yep. "Brownout"

The sudden impulse from 2 480's (what exact type do You use? ) and the high-speed gun recoil motor (if you use the "stock" recoil) on "fire" has a habit of overwhelming éven 2200mah 20c lipo's.

Not so with my 4000mah 30c LiPo's. It just often gives me a slight heart-attack with the 10w FS8 speakers suddenly making the -very loud- main-gun sound and all.. Yes... I should nót test tanks @ 23:00h

Orr.. there's something screwy going-on with the gun-recoil motor. I once had a short in the wires to the recoil-motor that would immediately trigger a shut-down. Which was a good thing tbh. Completely re-wiring the recoil motor and the flash-LED, fixed it.

See if it shuts down if You take-out the multi-coloured turret/gun/machine-gun connector, and hit "fire". If it does, the board is probably faulty. If it doesn't, well, back to "screwy recoil-motor"

But first, try a high-capacity battery. The 1800mah Lipo/Li-fe batteries that comes with the T-90 aren't the highest c-value, me thinks. 20c at best, which means it can deliver :

1.8 Amp x 20c = 36 Amp max.

Easily reached with 2 x 480 ánd high-speed recoil-motor. Making the voltage drop to a level where the IBU's Voltage Cutoff intervenes.

Btw. You can simply test if it's the 480 motors that cause the problems by switching the track-recoil to " off " in the IBU2.ini.

That is extremely helpful info. Thks.
