1/18 Scale SR-71 Blackbird

[avets8]

Hello everybody,

I'm building a 1/18 scale SR-71 Blackbird. I have another thread that I started in HPR thats got all my information on how I'm building it and the materials already up. I'll put the link down here so you don't have to go and find it.

Here are some pictures of what I've done so far. There are a few pictures in there of the drawings that I started with to get a general design. There is also one that shows a drawing of a panel that I took from a 1/72 model airplane that I built a few years ago. I'm using 1/4in birch plywood for the panels and blue insulation foam to fill in the gaps, then I'm fiberglassing the whole thing with 6oz fiberglass.

Thanks

What is the wing span?

This looks like a sweet project. What do you plan on flying it on?

[avets8]

It will have a 34in wingspan and it will be 63in tall.

As for what motor I'll go with, it all depends on what it weighs at the end. At first i predicted it to weigh between 6-7 pounds but I think now it will end up being more near 5-6. If it's on the higher side I'll probably use a 4G Pro38 I-470. If it's on the lower side might go with the 3G Pro38 I-350.

so its been a while since i last posted anything reguarding my build but as of right now its on somewhat on a standstill. i've finished cutting out the wood panels and i am continuing to cut out the foam pieces to go in between the wood. i have made a tube coupler/payload section to attach the nosecone and parachute and have made a baffle section. i will have pictures withing the next few days of all the stuff that i've done. i'm at school right now so i don't have any pictures with me at the moment.

reguarding the standstill, i can't start epoxying all the peices together until the tubular nylon that i ordered arrives. the problem is is that i ordered it a long long time ago and we contacted the shipping company and it was lost in transition between where we ordered it from and my home.

i'm going to try and keep doing as much as i can and hopefully the tubular nylon will show up and i can get the epoxying underway.

Do you have an REI store near you? I bought twenty feet of 9/16 inch TN for $4.40 there. Something to think about for future builds

we (avets8 is my brother) ordered 300 yds for 60 but as he mentioned it got lost in the mail, a 12 lb box went poof/was too damaged to continue to be shipped (says the note that was attached to the box clipping we got). But the REI idea sounds like a great solution to the problem thanks!

edit: found an REI about 20min from our house!
