So sorry to hear this man - that's a sucky situation. Unfortunately almost all of the advice or tips I might have are long past being useful to you here. Just in case they will help you out for the next time, I'll list a couple.
1) If you have a transmitter than has telemetry or RSSI signal strength indicator, you can use the transmitter antenna like a dowsing rod - when you point the transmitter straight at the receiver the signal will go down due to the donut shape of the radio frequency strength.
2) Install a beeper like the
Drone Keeper Mini - it's self powered so loss of the main lipo doesn't stop it from working, and it can be wired in to automatically charge itself when the flight battery is plugged in so you never have to remember to charge it.
3) If you have a HAM radio license, build or buy something like this
Lost Model Locator that broadcasts in the 433 MHz range and will broadcast for weeks on it's internal charge.
4) Install a locator streamer. I haven't been able to find the link for this today, but someone had a design that used a spring loaded rolled up streamer with a servo release mechanism in a 35mm film canister - the idea was either a manual release if you knew you were going in, or have the receiver failsafe release it automatically. A 10 foot bright orange ribbon can really help in locating something on the ground.
5) Find someone with waypoint capable camera search equipment. I know a guy here in Northern VA building out a fixed wing plane with Pixhawk for autonomous waypoint driven search patterns and high def downward facing video recording. He's been succesfull with this method using a multi-rotor to bring back footage for review, but is porting it to fixed wing for longer search durations.
Again, sorry that I don't have much help to offer with your current situation - but after 2 days in the woods it's pretty sure your battery is drained even if it wasn't ejected during the crash, and I don't know of any remote electronic wizardry that could help now.
