Step 2: The Shrink Process

This is basically how to shrink a plastic bottle over a mold with a heat gun.

Start by cutting off the bottom and inserting the wood plug.

I'm using a 2L milk bottle for a demo, so its way too big for the plug, but its just to show the procedure.

Next shrink the bottom of the bottle first to trap the plug inside. Then do the neck area, here I've cut off the threaded part to make the shrinking neater and easier.

One you're happy with the entire look its time to let it cool and the trim the waste so as to pop the mold off the plug.
<p>very nice work could you put a video</p><p>or it does'nt fly</p><p>anyway cool work</p>

this is a proper plane i will eat it later
buenos apetitos
*cough. what?
Would it be possible to make the rudders use via remote control or would that be too heavy?
sure, with another micro servo, but a waste of time and money. Its not necessary because the plane can be flown well enough on elevator and ailerons alone.
nice plane!!! what technique did u use to cove the fuselage? yours looks so much better than mine X(
Thanks, its the ultra lite version of the shrink film, after 6 planes you tend to get the hang of it. :)
where did you get the airplane plan or layout? what model?
Hello I'm also in to rc flying, Is this the plane from www.flymodels.co.uk?
Yep, I posted the link to the plans in Step 4.... .... Incidentally the plane is a 440 gram park flyer. Speed 400 aerobatic plans at Flymodels UK near the bottom of the page.
Great looking plane! I noticed the electronics on the website were a bit outdated- what kin of geartrain did you choose?
Also a geared 400. :) A brushless is about 6X the price of the 400
Very cool, I think this could work for ballistic nose cones for model rockets as well as dovetails. Thanks for the inspiration!
Good old school trick, have you tried making canopies this way, just have to have it go alone one of the sides and have a filler block to take up space.
Great idea! And I'm sure the technique is of much more general use than just in model planes. But sweet plane too.
I wonder if you could mold the plastic over the wooden frame of the body the same way you did the nose for the wings you would need a larger bottle
It would most likely add too much weight to the plane, that is if it didnt crush it when shrinking, also assuming you manage to find a 1metre long plastic bottle. On the other hand, if you just wanted an ornament, you could shrink bottles over a wooden form and then cut them neatly in half and glue the shells together again.
Nice instuctable. P.s. brushless outrunners are cheap, durable, lite, and no gearbox. You should get one.
thats awesome. ill ad it to the group
That PET-nose should add some well needed crash-resistance. Good on you.
Yea...this is only a 1/4 of a plastic bottle in the front. Nothing else is made of plastic, just wood. Not really a great entry for the contest.
true that, there are great plastic bottle instructables I've seen that aren't even in the contest
At first I thought the whole plane was done in PET .. silly me. Still really cool though.
yeah your not the only one
me too
that's a great plane! how does it fly?
