You will need to do something to stop the fuel spitting into fuselage. Jetpainter gave a few good ideas how to do this.

Thanks bro. I will look into that.

The DA50 looks right at home.

Good to see you making progress. Once they hit their feet, it seems like it is all down hill from there. I have a simple suggestion regarding your carb and the center hole in your firewall. I am wondering...do you need the hole there for clearance for the choke butterfly? If not, (which I usually plugged or did not cut open) a 1/2" or more gap between the back of the carb and the firewall is usually more than sufficient "open air space" for the carb to feed good. I can't see the back of the carb in relation to the firewall so I am just making a guess. If you have the clearance for the choke butterfly with enough air space around the back of the carb., I think I would just plug or block off that center hole.

Yup. I needed the clearance. I'll have to come up with something to keep fuel out of the fuse.

Here's what I did Mike.

And if you go to this page of my thread you'll see a cool Idea for it from @Pistolera https://giantscalenews.com/threads/50cc-scratch-build-from-my-own-design-revisited.1089/page-64

Thanks bro. That gives me something to work with.

I new jetpainter would see this he is the gentleman that helped me with the same problem of spitting into the fuselage. The box works great.

And the angle on the bottom let's all the spittle drain out.

Been slow going the past week or so on the Robinhood. I've been scratch building a cargo bay for it. I still have to figure out the linkage setup to open and close the doors. But other than that it's coming along nicely. I'll try to remember and get a pic or two of it the next time I'm out in the shop.

An epoxy cup was just the right size to plug the carb clearance hole. Glued it in with some Seal-All.

Couple pics of the cargo bay I'm working on.

When it's all done it will sit flush with the bottom of the fuse. And it will be removable for service.
