I’ve enjoyed my Crusader GT2 for over a year and it’s been a tank till it was involved on a moderate crash last weekend. Issue is that it wont arm (on a switch) since and flashes “LOW VOLTAGE” reading 0 volts on the OSD with a fresh battery. Running Bata flight, Teranas 9x w/Frsky control, 4s bats. The receive light turns green when firing up the Tx indicating healthy up-link. I’m somewhat experienced but this one is beating me so far. One thing I did notice was that 2 of the plastic screws that hold the board stack in place had sheered off so I’m guessing that saw some impact G’s.
This sounds like if your VBAT Connection has come lose…
Maybe double check if all cables are still attached.
If not resolder them or if you arent sure upload a few pictures. Maybe we know what to do.
Or just upload some pictures anyway
VBat connector swapped out with a spare - no love. Lipos are reading 16.8v. Interestingly, I cannot get it to connect with betaflight. Another bad board indicator perhaps?. It registers the right COM but wont connect fully. Any pointers on checking the steps there could be handy. If a new board, what’s the latest and greatest for this machine?
Great thank you - I’ll give that SW a shot tonight. Cable talks to my other quads (Kiss FCs) so that’s OK. I went ahead and ordered another board (Dlink-F3) for delivery this week. Looks like it plugs in with the same ports as the original so that’s handy. Fingers crossed it’s not too finicky to tune etc. Anyone upgraded yet? I love whiling away winter hours on setups but in the summertime; I…just want to fly. : )
Right - so close but alas. Tried to download the ImpulseRC fixer SW but my PC (Win 10 from work) said it had a virus. Tried to grab it from several other sites but got a download error. Could be the job’s got this PC shackled up some. Anyhoo…I’ll just put a new board in and share how that goes. Thanks again all,
“Good news everybody”…New F3 board came in, connected to Betaflight, and everything fired up nicely. Scaled the PID’s back a little and all’s well till the next crash. New rev. board has vibration isolators but otherwise I could not tell the difference. All OSD functions fired right up without any additional fiddling. Happy days and thanks again LUCA and DOOMEDFPV for your help. PS - the job’s IT guys called me about downloading driver SW on a company machine. So likely a firewall thing.
