This complements my quick and easy fin and body tube covering with packing tape technique.
https://www.rocketryforum.com/threads/colored-packing-tape-to-cover-body-tubes-and-fins.176518/
I cover the fins with tape except for the roots. Then I glue them to the body tube. Then I tape the tube.The fins are glued onto the body tube. but the body tube is pre-coloured with packing tape? do I read that right?
And the hot glue is then added onto the packing tape (on the body tube & on the fins)
How hot is the hot glue when applied / smoothed? And does that affect the tape in any way?
Paint? I don't know what that is.Does it take paint?
Yup.This stuff ?
Yeah, that would also be my concern. There are various flavours of hot melt glue, but being a low melt (and even lower GTT) thermoplastic (and a soft one at that) I'd be particularly concerned on really hot days.That looks good. The hot glue I've used has too much flexibility, but it's probably something different.
I don’t think you need to worry about ambient temperature. Here is a YouTube channel of a guy in Arizona who builds RC airplanes and drones using foam board, packing tape, and hot glue.And the Summer sun heating the glue.
I would think that the airflow would keep temps down in flight.It's not the speed of the flight that is likely to get you, but the motors heating up and loosening the glue. Long burn motors are worse.
While on the pad waiting to launch?I would think that the airflow would keep temps down in flight.
It does, except at discontinuities where there could be stagnation and heat build up, but you already said you're flying it below Mach, so I agree that heating shouldn't be an issue. Also, you have two layers of paper, which isn't a terrible insulator, between the fillets and the outside of your motors. Heat transfer takes time and rocket motors burn fast (relatively) so your fillets should never be exposed to too much heat from a motor.I would think that the airflow would keep temps down in flight.
I haven't flown that one yet, but check my thread on bellyflop recovery. Except for the Dragonite, they all use hot glue. It isn't rubbery.Flexibility was my primary concern. Fly it and find out.
Thanks!I like the creativity. It is absolutely not a 'one size fits all' solution, but it is creative and I bet will work under a lot of fun flying situations. I think questioning the typical methods and approaching alternative ideas responsibility (i.e. not hey y'all watch this!) is a great way to become an expert and @sr205347d is doing that, IMO. Love it! Succeed, fail, learn, share. Nice!
