I purchased the factory balance weight set as I think this aircraft will turn out to be a little nose heavy when complete. The taildragger fuselage is easily tipped on its nose with the engine & propeller installed without the wings & tail in position so I have temporarily installed the weights as a preventive measure for the upcoming engine installation phase of the build. The cut-outs for the wiring did not align with my wiring so I needed to file the steel plates to allow clearance. If it transpires that one or more of these weights is required prior to flight, I'll tidy the installation.
