Like most, when Xenalook first posted I checked their online site. When I saw their add in Flying Models I look again.
This time I found that they had added prop nuts for the old Space Bug, Thermal Hopper, and Space Bug Jr. @ $6.95. Couldn't resist! Promptly placed an order (which was quickly filled) for those nuts and some other stuff I couldn't do without.
We had an online discussion a couple of years ago about someone making these but nothing ever came of it. I will post this on several forums since many probably need these to restore an old engine...I needed four. Oh yes, they come with a stud so you can use them on modern Cox engines also.
Here are some pics. The TH on the left has the new nut, the right one has the one that came with the engine. Close up of new one and original one. The other three went on my Space Bug Juniors.
