DF95 to US1M conversion kit

thingiverse

This is a base level conversion kit to make your DragonFlight 95 into a class legal US1M. This boat conversion is sometimes known as the Dragonstein. https://www.rcgroups.com/forums/showthread.php?2964063-DragonStein-DF95-to-US1M-conversion The main part needed is the tailpiece. It extends the hull length to meet the class minimum. I have been calling mine the “stinger”. The second part extends the keel fin. When used with the stock DF95 ballast bulb, it extends the full depth to just under the class minimum. It is optional and not required to be class legal, but you should use it! -These min. and max. measurements are based on US1M 2017 class rules. There are FDM and SLA versions of each part. US1MstingerFDM.stl - The FDM tailpiece was my original design. It is bulkier than the other version, but prints well on a filament printer. It will print directly on the bed with no supports needed. US1MstingerSLA.stl - The SLA tailpiece is my 2nd version. It is lighter and sleeker. I had some folks ask if this scoop holds water. It does not. It self bails just as any boat does. I have not tried to print this with an FDM printer. US1MstingerSLAsupp.stl - This is the pre-supported SLA model as well. It works for me. If it doesn’t for you, then use it as a guide to do your own. keelspacer.stl - This is the basic heel spacer file. keelspacerFDMx2.stl - There is the FDM specific file that is actually 2 spacers placed so that they allow cooling time on each layer as the head moves from one to the other. Their thin ends are placed so that any stringing happens there. This will make a nicer print than just printing the single spacer alone. No supports needed. Print on the bed. keelspacerSLAsupp.stl - This is the SLA pre-supported keel spacer version.
