Hi Gents
Long time no post. After my terrible horrible no-good day at LDRS 36 I am finally back at it. I will have my Mongoose 29 finished and will fly it at this coming Rocstock on everything from a G80 to an I205...unless... I have an Eggfinder in the nose and an Eggtimer Quantum in the coupler. I found Cris Erving at LDRS an he just so happened to have the exact same bird with the same electronics to fly. I took pictures of all of his attachments and I am building my own bird accordingly, with a couple of exceptions. I chose to overengineer the mount for the Eggtimer.
Here is the CAD
and here is the actual purple fitting 3D printed from Shapeways.com
Funny how reality looks just like CAD.
The other exception is this. I don't know how Cris attached the nose to the payload to the coupler to the sustainer.
Here is what I propose. I want to have the nose be just a slip fit into the payload with adequate venting to prevent drag separation (on an I205). I also want to use one 2-56 nylon screw per joint to attach the payload to the coupler to the sustainer like this.
What do you think of the slip fit nose and what do you think of the nylon screw attachments?
I have a bit of time before I commit. I am going to paint the green stuff you see in the image and take my time. Then I will drill vent holes and nylon screw attachments.
Thanks
Tom
