This is my next foamy scratch build project. I have part of it cut out and I'll post some photos when I start building.

Update: The parts are all cut out except for the rudder and elevons. now I have to figure out how to wire up the LED lights that I'm going to embed into the wings and the fuse before I start assembly.

Update: I spent some time this afternoon deciding what to use for LED lights for this plane. I hooked up some LED light strips that would look good but the drawback for me is they are heavy and they run on 12 volts. I rigged up 3-5 mm red lights in a series just guessing what resister to use and it did work. I just have to figure out the best way to solder 31 aug magnet wire.
I've rigged up a few other planes with LED's for night flying and got lucky guessing at the resistor size and using a single cell 150 mah lipo for power. I used 32 aug servo wire and it only weighed 5 grams with the battery. I've also lite up my Axial Wraith like a X-mas tree ( I think there are over a dozen lites on it ) just guessing on the resistor size also.
I did some searches and found a couple of LED calculators to figure out the right resistors to use. Here's one of them.

Now I just have to figure out what lites to use and order some resistors.

Update: I've been out flying my 4F-P51 for the last few days and not working on the light setup for the delta.
I figured out how to power...Continue Reading

Well I've caught the foamy scratch building bug. I've built 3 so far and have started on a fourth.
The first two were built using Dollar Tree foam board and the third is made from depron. The first one is a 4-F P-51 from plans found in the foamy scratchbuilt section. It flew pretty good once I got used to how it flies. it really needs some rudder to get it to turn. You can't just bank and yank it around. It got beat up pretty quick so I decided to make one out of depron.
The second plane is just a delta wing I drew up on the DT foamboard and used some spare parts I had. It flew but was very twitchy and was not a little floater as I had hoped. It's sitting in my hobby room and I might make a new one or make some changes to it in the future.
The third is my rebuilt 4-F P51. It really flies great and is much stronger being made from depron, I can really see and feel a difference by the way it flies. It's really a fun plane that I fly every chance I get.
I've added a couple more scratchbuilt foamys to my collection,...Continue Reading
