howdy all,

basically I'm new to everything, been lurking on some other forums and stumbled over here.

Basically, I havent been flying long, and 3D is beyond me at this time, but you have to start somewhere.

I was going to build a www.foamyfactory.com 3DX electric to learn with, but started pricing out lipo's, chargers and such and realized I'd be jumping into a pretty decent amount of $$$ just to get something flyable. then I look around at the shop and see an old OS .15 laying there that needs a little lovin'. The 3dx isn't that far off of the mini 3D's size from what I can tell, so I'm going to build a custom .15 powered 3DX. Getting the CG back is gonna be a bitch though with the .15 and a 2 or 4 ounce fuel tank on the nose.

I think it'll be interesting at least. I'm also building out of X-acto 5mm sturdyboard instead of just straight depron, since that's what I found locally.

If it all flies like $hit , then oh well, I'll ask the wifey for a Mini 3D for my birthday in July and swap all the components over to that.

Just thought I'd say hi.

here's a few pics of the progress so far...

it's my first profile plane, so yell at me if something doesn't look right.

from plans:


to parts:


to parts with their carbon spar reinforcements:


In that last pic you can see the motormounts I cut out of carbon fiber, and the .15 I was using while making templates. I added an extra 4mm carbon rod on the lower part of the nose to help reinforce the motormount area.

Yo,

The only problem I see is in the first picture.

That Corona looks to be only half empty! :lol:

That looks like it'll be fun. Be sure and get some flyin pics. How are you gonna fuel proof it? Just curious.

Don't worry, I took care of the rest of it, and it's whole family.

But right then I wanted to be able to cut straight lines :)

I'm thinking I'm going to cover it with vinyl sign material. Buddy of mine has a shop and I can get scraps from him. I'm thinking fluorescent green, black and chrome.

I'd monokote it, but I'm kinda scared of the foam and heat. Plus I don't have the monokote, and the vinyl is free.

cool vid
Mine built off ot the regular sized 3dx plans. since I didn't use fan fold foam or Depron, but the sturdyboard instead, I'm hopin it's not too heavy for hovering. Got a reccomendation on a prop size for it? Lowest pitch I have laying around is an 11 x5, only smaller props I have are 10x6, 9x6, 9x7, and then 8x3's for my SSC planes.

I have no idea what ate final weight is going to be, but my servos will be in on Tuesday.

I should have it assembled by Friday or so , but I don't have a micro receiver for it.

A buddy ordered a Hitec feather 4 though, I might be able to swipe it for a lil bit, he's not going to have a need for it until he sees mine flying anyhow.

here's a few more pics on progression.

Carbon fiber engine mounts, nosecone plates are made, and engine is testfitted.

i was going to glue the elevator halves together tonight, but had to do some fiberglass repair on a friend's wakeboard instead.

Nice. I had a lot of fun with mine. Monday (March 30th) was my birthday. I went out flying, got cocky and was hovering it at 0 error height.....I had an error :D

I decided to ditch the glow fuel option, just to much trouble trying to fuelproof it all. I decided I would rather have something I can fly in the front yard without bothering the neighbors too bad.

Keeping the same fuse, just cutting everything out for the GWS gearbox.

My powertrain I'm planning on installing:
himax 2015-4100
GWS d-ratio gearbox with the allerc.com himax mounting plate
Castle Creations Phoenix 25 ESC
for now I'm holding off on lipos, as I can't afford the charger I want. I ordered a pair of 12V 10 cell nimh packs. Got them here: http://www.batteryspace.com/index.asp?P ... ProdID=907

the specs look good for the price, and I have a nimh charger already. Hopefully when I do go lipo the drop from 12V to 11.1V will not be that noticeable, plus I can double my runtime by using a 3s2p lipo setup built with 1200mah cells for a 2400mah capacity at less weight than the 1100 nimh.
