After a good crash, highter to direct on the nose at 45 degree angle, my F45 spin the same in the video, the maine blade seem to slow compare at the rear blade. I think i burn my money in this crash It's a costly first 5 minutes of flying hehe.
I guess we have to wait until one of you that have this issue start replacing parts to see which component is damaged. Again, my guess is the gyro on the PCB.

Due the similar problem several of you have been having with the gyro, I am going to suggest a preemptive fix.
I have several helis using the HK401 gyro. Inside to gyro, there are 2 circuit boards soldered to the main mems gyro board. These are know to come loose and break the solder under hard flying or crashes.
I have been using clear epoxy to strengthen the 2 boards where they are soldered to the main board.
I would suggest using a small amount of epoxy on each side of the gyro where it is mounted to the PCB to strengthen it.

Thanks so much for this. Its really help me interms of items to purchase for the mod. Next is how to connect the circuit to make it work and what are the connectors involved. I'll try to catch up with it slowly.

Btw, you are using 11.1V 1500mah battery. Wonder whether it is too much for the main motor.

Regards.

Yes he is using an 11.1v 3cell Battery for the main motor, but since it is a Brushless motor designed to be run on an 11.1v battery, it is just fine.

What I meant is I'll try to dig it by myself from the forum and try to understand it slowly. Sorry for being so general

techNtoys on Amazon has most parts and they ship from CA. I had my order on the East Coast in 3 days.

my rear servo has started acting up.
It intermittently goes to full forward extention (way past its normal range of movement) when I bind it and stays there.
I tried the other servo plugged into its place on the pcb and it works fine - so can I assume it is pooched and I need a servo? Is this common?

Here is the link for the servo arms only. $3.00 US each.

No, it is not common. It usaually only occurs after a crash that puts extreme load on the servo when it is powered up stripping the tiny plastic gears.

When you charge more than one battery, they would need to all be discharged the same amount.
To charge in series, you would need to set charge rate 14.8 volts to charge 2 batteries.
The best method of charging is to use a balance charge the ensures the voltage in each cell is charged correctly. That is not possible with most chargers unless they are a special gange charger, which would be very costly.
