I originally built this in my early twenties (I'm now 71!) and like many other people it just got stored away until the lockdown when I decided to refurb it for something to do! Repaint, new motor and new radio gear plus more accessories which I got from SLEC. These were such things as window frames, tow hook, mast, fire monitors, air vents, decals and crane. The front wheel house windows of the current model that they produce are a slightly different shape to the original Aerokits version but I traced my windows for them and they very kindly produced a matching set of front windows! They are extremely helpful to deal with. Worth a visit to their website:-
The crash tender fittings are at the bottom of this webpage. Good luck. Cheers Duncan
P.S. I have also put this on the Motor Alignment discussion but I thought it might also be useful on this article for any one considering refurbishing one of these models.
