With the arrival of the Quadcopter kit I dug out the other parts I had ordered.
I was looking at the GorillaBuilderz shield and noticed a minor technical problem. The SDA & SCL lines for the I2C are not socketed.
Will need to mod shield before I mount the accelerometer & gyro so I can get I2C working with Netduino plus 2

Sorry to hear that we supplied you this shield without the correct connector populated. We can assure you that the GorillaBuilderz LeoShield is now fitted with the proper 10 way connector.
Thanks GorillaBuilderz replacement shields have arrived and the first one is working well. Posting in the next couple of days to show progress.
