...fitting the Trainstar replacement motor
Having struggled to get a replacement prop adapter for the Trainstar, I finally decided to get a whole new motor, the D4023 850v from Hobbyking.
This seemed rather wasteful as I only really needed the adapter, but anyway. The D4023 comes with a steel prop adapter, hopefully more durable than the Volantex aluminium item but is otherwise pretty much a direct equivalent replacement.
The D4023 does actually have a different mounting pattern on the bell mount, three holes instead of four, but fortunately the Volantex saddle mount has a multi-hole configuration which accepts the three-hole pitch with no rework required, which is great.
So the installation is a pretty simple switch-out; even the wire length is just right. The only extra work required is that the D4023 doesn’t come with any connectors, but a few minutes soldering got some 3.5mm bullet connectors fitted just fine…
