[FONT=Verdana]My son and I have built over 100 RC Powers Jets.
[FONT=Verdana]Buy a good gun, both Scott and Dave use a[FONT=Calibri] ARROW TR550 Professional Hot Melt Glue Gun, 120 VAC, 40 watt, 380 degrees Fahrenheit. I bought mine for $16.oo .
Have everything prepared before you pick up the gun. Work fast. Use a continuous stream of hot glue. For me, a little seepage is good. After you apply the glue and put the parts together, using a piece of scrap foam as a putty knife to smooth the hot glue down makes the bond a lot stronger. [FONT=Verdana]Foam scraps are cheap, plentiful, handy and make excellent putty knifes (glue speaders). One time use, then just cut another one.
Maintain the hot glue by drilling and [FONT=Verdana]wallowing
out the tip to keep it clean and the glue flowing fast. Clean the tip often or its flow will diminish
, then clog up.
The trick to using a 40 watt gun is, that clean tip allows you to run the steam fast, and do not mash the glue in
with the gun tip. Just lay a line of hot glue, put the parts together, then use the putty knife trick. If you press the glue on the foam with the tip, it will
melt the foam. When I spot glue (like making repares), I have seen the glue get too hot when gun has set on and unused for a couple of minutes, I wast some glue off to the side to get to cooler glue, then I go to work. When I running a steams, I have not seen that problem. When I am putting a plane together, I use the gun soon as its hot enough, then I work fast.
I use the long glue stick. Running out of glue in the middle of the steam sux.
Another good trick: When the stick in the gun gets short, hot glue a new glue stick on the end of the short one. That way, you never run out!!
