I am happy to report the nameless kit now has a name......."Modkat".

Just talked to David at BVM and he gave me the green light on the name! I really didn't need to call BVM for this but there still is honor in RC.

The Modkat is born

Very nice, if the kit comes in at the price range you mentioned, it will definatly be on my list of planes to get. Can't wait to see the final product.

Hey Bob,
You deserve most of the credit for this one. As many times that you have used "'k"'s in place of c's I am surprised you didn't get it first time around.

I can do one better.... I need an experienced builder to be the "guinea pig" once I get the bugs worked out of the prototype. All that I would require is a detailed report of pros/cons once the build is complete. Then I can release it to the public.

Bob, you up for it?

Fuse Design-Phase 2

Phase 2 is complete. The fuse has been mated with the wing center and the appropriate cuts have been made (figures 1-3). Had major issues when trying to incorporate a cowl because I had to widen and elongate the fuse to make it fit. Structurally it would work, but externally it was just.......ugly

(figure 4). It really ruined the "speed" look of the Modkat, so I'm leaving it off and sticking with the original fuse design (figures 5 & 6: fuse front and rear view).

Once the fuse was cut I spent a good chunk of time fine tuning the canopy shape (figure 7). The change is very subtle but makes it look a little faster even when standing still

. To smooth out the underside I added a belly pan (figure 8). The belly pan will be molded it out of fiberglass. Then glued to the bottom of the wing center with epoxy and micro-balloons with scrap balsa underneath to support it. I would continue on and install the hardware, but I will not have the engine for another 2-3 weeks

. The muffler will be routed through the fuse and I'd like to have accurate measurements before starting that.

In the mean time, I'll start designing the twin booms and elevator.

More to come,

Mods

Very sweet. Can't wait to see the final rendering, let alone a first prototype.

By the way, I looked through the postings you linked to and also did some other research online about how to do fiberglass molds. It really doesn't look all that difficult, but I would imagine that the first few attempts would be challenging. I've actually started considering doing a mold of the fiberglass cowl I'm going to do for the Sig Somethin' Extra I'm building right now so I could reproduce it, not sure yet though. An initial investment for tooling gel coat, release wax and the various weights of cloth wouldn't exactly be cheap, but I'm sure it would be fun.

Keep it up!

Making a cowl is an excellent way to earn your fiberglass wings. Have you heard of CST Composites? That's where I buy all of my fiberglassing supplies and they even have a tutorial detailing the entire cowl making process. If you have questions call their customer service and they'll issue even more pointers. If you want to make a balsa cowl I also have an article detailing how to do that, but you would learn more trying the fiberglass technique first. In RC, fiberglass is your friend

Give it a try. You might like it,

I didn't mean to give you the wrong impression, sorry about that. I'm definitely not a newbie when it comes to fiberglass. One of my other hobbies, which has stalled out for the time being, is high power rocketry. On the most recent rocket I built, I wrapped the entire airframe with fiberglass and vacuum bagged it. Not a quick job, but definitely fun.

I have also built a rocket out of nothing but fiberglass components (commercially bought, I didn't make them). Pretty much the only things I haven't done with fiberglass are molds or something like a one-off custom cowl over a shaped foam core, which is what I'm going to do with the Somethin' Extra. And yes, I have heard of CST Composites and have gotten stuff from them before.

LOL! Now I will attempt to remove my foot out of my mouth

. Rocketry? That's what got me into r/c. Nothing above a "D" size motor, but it was fun.
