This is the second time I’ve built a Graupner Hertha Jeep. I built one a few years ago, and after a few runs converted it to brushless. She was my “go-to” boat for almost 2 years until an altercation between her and JPs Kitty II caused the loss of her superstructure. Well, JP had a brand new SAR kit in the box, untouched. We made a trade that involved, among other things, my Acapulco plus my old SAR boat for his kit and a couple of other items..it also involved me building a new, scratch built simplified superstructure for the old SAR. I’ve got that done, and am now in the process of building my new Hertha Jeep.😀
Now, I’m not going to do a step by step on this boat, as I covered a lot of that in the last build. I will, however, detail what I’m doing different because of what I learned from the last build. My old boat was built pretty box stock, with the exception of a hotter wind 400 sized long can motor. Unfortunately, if you drove the boat at full chat for a bit that motor would get pretty warm, and the stock motor was worse, so I swapped in a 1450 kv 28 mm outrunner. That motor on 6 cells gave the boat a good turn of speed, and never got much over ambient temperature…the boat was a reliable as anything I’d built after that. However, the radio tray/motor mount was designed for a can motor and strap down mount, and with all that in the way made it very difficult to install an outrunner..,.soooo…..
The first thing I did was to check the bottom keel for straightness. In my first boat the keel was tweaked near the aft edge, I had to cut out the offending piece and reglue it in place, with subsequent filling and sanding. The new keel was tweaked, not as dramatically as the first but more subtly, but the bend was longer. I had to cut, break, tweak and fill this one too. This, except for the instructions, was the only real flaw I found in the kit.
I decided to forgo most of the radio tray except for a couple of bottom former halves, I used those to make a base for my rudder servo mount. I also made up a bulkhead mount for the outrunner. Once everything was epoxied in, I did a test run. I got my alignment about spot on as this setup is much quieter than my old boat.
I did the cabin a little different too. The cabin pieces have “fold” lines molded in so you can crease the part and make it fit properly, like the front cabin windscreen. Now, the first time I built this boat I had a heck of a time getting the front screen assembled properly, and had to use a lot of filler. This time around I just changed up the assembly sequence and things went much better.
That’s where I’m at now, the cabin is mostly assembled and the rudder tube and propulsion parts are in place.I need to build the aft well deck and start getting ready for primer and paint.
