Expanding Foam or call the Gorilla
From: Ken Bauer
I recently discovered that an F1A wing panel was twisting too much under
load due to a broken rib inside the carbon D-box apparently from a nasty
landing. As I starting thinking and discussing with friends how to attempt
the repair my thoughts turned to the cans of expanding foam available at
Home Depot for filling in gaps in home repairs or for insulation around
windows and doors, etc. This is polyurethane based stuff that squirts out
of a narrow tube and quickly expands into a lightweight solid foam. But I
worried about getting too much inside the D-box which might make it balloon
up or explode making my problem much worse.
I remembered that polyurethane glue has some of these same characteristics
so I started experimenting and came up with a great solution. I had some
Gorilla Glue which is polyurethane and tried mixing it with water and found
that it expands into foam at a very nice slow controllable rate of about 15
minutes to end up at many times the original volume.
Here’s the method I came up with:
1. Get some gorilla glue and a syringe designed for glue with an outlet
around 1mm diameter.
2. Drill a hole about 2mm diameter in the D-box near the damage as the
injection point.
3. Squirt a couple inches of the glue onto a paper card just like you were
going to mix epoxy. Then spray a little water into it two or three times
while mixing with a stick, again just like mixing epoxy. After a minute it
turns to a creamy white color which means it is ready.
4. Stuff the goop into the syringe and then inject into the D-box.
5. Any excess foam will expand out of the injection hole as the stuff
expands and cures inside. Just trim off the excess and cover the hole with
a carbon cloth patch and the job is complete.
I ended up injecting this stuff at several spots I thought were weak and
the problem was fixed. The D-box feels very firm and stiff wherever the
foam has filled it up. I recommend just mixing some of this stuff up and
watching it expand as the first step in getting familiar with it. It could
also be useful for many other repairs such as holes in solid balsa glider
wings or even to mold small foam parts.
Hope this is useful, Ken
What’s the problem more and more .
Hi again thanks all for interest and comment .Allard yep of course over time I have had a few flights timed that robbed me but Ha Ho that’s the game .On balance I have had the correct time recorded and hence can not complain. One example Stonehenge a few years back ,a round timed by Russ Peers the model past behind trees and a ten second count down was done, result time with ten seconds removed from when watches stopped,2 mins 59.5 seconds so sub max on card like I said you win some and loose some .
Now certainly in the UK FAI models and competitions draw less interest than home grown events mainly because FAI models are full of technology that in the main is not liked. I am sure across the rest of the world if we had simpler models we would increase interest (with out even going in to the cost of this technology)
It follows that if we adopt an altimeter timing option it will become the norm again requiring the purchase and fitting of the equipment . Remember every one ant using electronics in their models !
One other point is for an altimeter timing system to be acceptable it would require a common specification and standard testing and calibration ie an ISO or CE approval
Can not see this happening as most of what we use is from cottage industry .
The real issue is we have models that are to good the potential performance far out stretches the sites that we use .
Having been a regular contender at the winter ice contests on frozen lakes when 99%of flights land on the ice and with flashers u get the full flight time BECAUSE you can see it land . The problem occurs when models as my demo above out fly your site and enter areas of obstacles .
CIAM needs to rethink how we conclude a contest . World and Euro Champs flown to 5 rounds will just add to more competitors flying in final rounds with longer flight times.
Before we just blindly go ahead and use altimeter timing lets look at the real problem to much performance .

Revised Sept Am Cup Update
Thanks to all for corrections and missing contest results. These additions and corrections did make several top 5 standing changes so take another look. The end of this flying season will have many close races. I will, as always, welcome corrections, email to
