I believe that's 24 hrs to a full cure, like other glues, strong enough to keep building probably happen a lot sooner.Wow, 24 hrs on the dry time sounds like forever. I might start using the gorilla glue that expands as it cures again. spritz it with a little water it will cure in about 4 hours. (Or attempt to be less heavy handed with the hot glue)
Will have to look into the minwax. Is this the same stuff you would apply to woodwork with a rag, or some kind of spray finish?
I appreciate everybody's patience with all the questions... thanks luvmy40
I don't know which Gorilla Glue you're using, but the White Gorilla Glue cures much faster than the brown stuff (Bottle says 80% cure in 1hr). There is also a Clear Gorilla Glue that doesn't foam at all, which some people like, but I don't have any experience with it personally.
When building light I like to use white Gorilla Glue and BSI Foam Cure.
There are basically two kinds of Minwax for foam planes. The oil-based variety is used to waterproof the paper on foam and/or to seal the foamboard to take spray paint without melting. Use as Mr NCT describes.
There is also a water-based Minwax (can be any brand really) sometimes referd to as WBPU (Water-Based Poly-Urethane). It's often used for sealing raw foam and laminating lightweight fiberglass or tissue paper over foam. It's not for anything structural, but it's an inexpensive, cosmetic stand-in for a laminating resin.
It's typical for upper wing to have more incidence than the lower. Because the wings are forward-staggered, when the upper wing (and forward of CG) wing stalls first it will drop the nose. This is a desirable behavior, because it automatically begins the stall recovery. Sometimes, especially with a high incidence, the nose drop can happen pretty abruptly. Too much incidence on the upper wing and it can climb pretty dramatically when power is applied, and the upper wing will stall long before the lower wing, making slow flight a fun game of chance.PS hadn't got the tommy out to test yet, but took my 40" span Dakota bipe over to the test " hopping spot" where it took off , got about 20 yards downrange, then flared up into a stall, then dove into a fence. Wind was a little gusty, but was also still messing with down trim. Think it's balanced out fairly well, so not quite sure what to think. If the upper wing had too much incidence could that cause it to act this way? Had my daughter trying to catch it (unsuccessfully) on camera. But will get a better angle on it for the next flight.
As always, I thank you guys for all the cosmic knowledge.
If your bipe pulled into a stall on its own after flying reasonably stable, I don't think wing incidence is your problem. But, I've been wrong before.
