I have never used either of these glues. Is one better than the other for foam? What are the advantages of one over the other? thanx!!

It depends on who is selling it to you.
I have used both and are similar but Foam-Tac is much more expensive in the UK.
As an alternative to both there is BSI Foam Cure.
Each individual has his or her own favourite and there is not much to choose from each 3 regarding performance.
There is some difference to how the cured product sands to a finish.
I have found that the BSI foam cure can go off in the bottle but Uhu Por will stay fresh as long as you replace the cap after use.
Wot, no Depron?

We used to sell foam tac on http://www.frcfoamies.com but then Beacon Adhesives began selling direct so we don't sell it. I do still use it though! I think Foam Tac is the best stuff for MPF or Depron out of all the products I've tested. I did a test between foam cure and Foam tac. Foam tac has quicker drying and better adhesion but foam cure dries hard and is easier to sand. I use so little foam tac that the sanding it isn't really a factor, so I prefer foam tac.

Foam-Tac and UHU-Por are very close, I do prefer the UHU over the Foam-Tac because it is in a tube rather then a bottle. The BSI Foam Cure is good but like F1 said it cures hard so where you do want the glue to flex like hinges then it doesn't work so well. The BSI stuff though is around half the price compared to UHU or Foam-Tac so I always keep a bottle around.

Next time you are in Dollar Tree buying foam, perhaps have a look for this glue.

I have been able to get it at Dollar Tree in Canada, it has the exact same properties as BSI Foam Cure, dries light and strong (I have planes with over 300 flights on them in all temperature conditions) and durable. As mentioned, it is not flexible, more like epoxy, but does not require mixing, is sandable and a little goes a long way.

I pay about $1.25 Cdn for a 1.7 oz bottle, so it is about half again cheaper than BSI Foam Cure and works great.

Best of luck with whatever you choose to experiment with.

Cheers,

Scott

Wow, that sounds like an absolute bargain.
I wish we had it in the UK.

I've had my eyes open for that in my U.S. DT but haven't seen it yet.

This video might put you to sleep in a few minutes, but it is a discussion of the glue and tapes I use when building my park jets.



As Ian mentions above, there are all kinds of products to use to build these planes. I think it boils down mostly to what you can get, what you can afford and what works for you in the long run. I recently built a Mig-29 V1 for a park jet beginner build video series I did on my Youtube channel with only hot glue and epoxy (epoxy for the spars, motor mount, control horns). Using the Flite Test method of using scrap foam to scrape away the excess hot glue, I managed to build a pretty light but strong plane so it can be done with hot glue also

Best of luck experimenting to find the glue that works for you

Cheers,

Scott

Although hot glue is very useful for fast builds and I used to use it a lot but now my preference is more for Por.
The reason for this is that hot glue can leave annoying strands like fine monofilament that can barely be seen hanging from the air frame and can really spoil the finish when it comes to painting. I am not that fussy but for folk that like a pristine look, it can ruin the look.
I don`t consider foamies as a long term type of model as I try to push my planes to their aerobatic limit and quite often go beyond my flying abilities which can result in more than the odd crash.
Like Scott stated I use mainly Por but when I need a fast grab I will spot weld with hot glue.
Another thing I have found is the quality of the hot glue and the HG gun. I would recommend going for an expensive glue gun with variable heat settings as some foam have lower melting points than others.
There are post on Youtube that show methods of making temperature control units for glue guns.
After buying around 10 different cheap guns I have bought an industrial quality one but it is too hot for some foams so you must be careful. I sometimes have to regulate it by turning it on and off so I don`t melt the foam.
The previous gun I had was a fairly expensive one that was mounted on a stand which provided the power and you could then walk from one end of the table to the other using as a cordless gun.
At first I thought it was great but when it was in it`s stand for any length of time the glue would pour out of the nozzle and I was getting through hot glue like crazy.
Spend a few extra bucks on quality glue sticks get the clear ones as the milky cheap sticks are not very good.

The other key component to using just hot glue, DON"T forget your plane in a hot car. The owner of the hobby store left his combat planes in the car (at the club while waiting) , when he went to get them all the wings were coming apart. He looked at mine and said why??? I said use hot glue sparingly as a backup or spot welding but other then that I use real glue . Mine were in perfect shape.

Great video Scott. I think you covered all bases regarding adhesives

A very good point Jeff
I really don`t like the weight of hot glue and I reckon when some people start in this hobby they may think more is better and it isn`t.
