A while ago the Radjet slowed down a bit, becoming somewhat pedestrian to fly. At this stage I decided to do a battery swap with the Rarebear and run the Radjet on 4S battery instead; the little buzzy being alarmingly fast flying on the high-voltage pack.
Recently, however, the Radjet suddenly regained its mojo and became seriously fast, carving up the sky in a most endearing manner. Unfortunately, this resurgence of speed was short lived with the Radjet reverting to its previous underwhelming state. The bearings in the stock motor being the main suspect.
However on my spares shelf I happened to have a spare Funfighter motor whichwas too good to resist as a parcel-filler with a previous purchase. Deciding this was the time, I set to stripping the old motor out of the Radjet.
This is a relatively simple process although, with the motor mount being bonded in as part of the rear fuselage section, you have to rip it out which is not great. However it came out easy enough nevertheless.
A few minor complications surfaced; the Rarebear motor requiring two sized mounting screws, M3's and M2.5's and, while I had some of the latter, I had none 30mm long so had to improvise somewhat. Also, the Funfighter motor comes with mini-bullet connectors, however I unsoldering the 3mm connectors from the stock motor and fitting these to the new unit solved that hiccup easily enough.
So the Radjet is now all set up and waiting for the glue to dry before I take it out and give it a good blast around the paddock. I'm looking forward to that...
