Thanks for noticing them! They are Robart Part # 305 hinge points and I love them.

IMO, they work great in depron models, have extremely low resistance and I have not had a single one fail on me yet on multiple planes. 3Deranged (the awesome Clik-XL guy) turned me on to them awhile back and I've dumped tape and CA hinges since then. You only need a couple and the smallest brush of epoxy and they will stay secure for a very very long time. I'll put some petroleum jelly on the axle to keep the epoxy out of it and use a pen drill to make a very simple hole. Once the epoxy is cured, work it to loosen it up and it will just flop around effortlessly.

Downside is you need to double bevel your surfaces and have a sub-millimeter gap.

Hi guys in an effort to keep the weight down on my next f3p build i have been told (by the brill Aio1) that there can be a big difference in the quality and weight of depron? i bought my last lot from www.depronfoam.co.uk and i am very happy with the quality of the goods bought and service but wonder where others buy thiers from? is there a higher grade/lighter depron supplier that anyone knows about?
many thanks

Actual "Depron" shouldn't vary too much. It's normally about 120g/sqm but I think there are several other similar foams around with different densities.
If you want lighter I'd suggest trying Extrupor/Gediplac if you can find it. If I remember correctly it's about 100g/sqm.

Depron Aero (Formerly Gediplac) From RC Foam.com would be a good candidate for F3P

Description Depron Aero (formerly Gediplac) is similar to Depron except lighter! It is approximately 20% lighter with most of the same look and feel as Depron. The finish has more of a sheen to it than Gediplac had. These sheets are great for many of today's indoor and competition foamies.

The 3mm Depron Aero is great in applications where weight counts.

I've been thrown off a few times when I've received batches of 6mm depron that came out to nearly 7mm. I actually liked it for the larger stuff but it screwed up the tooling on some big CNC equipment, resulting in cuts that were perfectly 6.2mm by design and all of it had to be re-pathed to the 6.85mm range to actually cut through it. Went through several sheets before realizing the problem was the depron and not the code/calibration! At least rcfoam.com was kind enough to knock a few bucks off my next order. They are as subject to the quality issues as well, since the foam they don't cut themselves comes pre-cut from the factory.

Always an awesome supplier if you are north America.

Guys, Iīm finishing a Troll, and I would like anyone to suggest a good CG for starters. Then I can go fly and find my sweet spot, but I donīt like the idea of tossing a brand new plane without even a starters CG. Thanx in advance!
