Need more details to really tell you anything...... Is it a built up balsa version of the 3dx with the same areas/ moments etc?
My little experiment.

Oh, so the circle jerks at the LHS think it will work them it must!!
i ment that to be funny, not a slam to your LHS or you, i know how it sounded though. i'm not really a dick, Honest
this is sloppy and fast...
If i'm writing way under you i'm sorry i'm assuming your new to this stuff. ok lets look at the problem cause i now belive your not full of shit.
one of the reasons a 3dx flys as good as it does at that size because of its wing loading being so light.
to calc wingloading take the wieght in Oz and divide by the wing area in sq feet, for shits and giggles lets say the 3dx had a 12oz weight and a wing area of 432inches square thats 3 sq feet so 12/3 is a wing load of 4oz/sq'
said like 4 ounces per square foot. os thats with a 1.5 oz motor and a 5 oz maybe battery and a 4 oz airframe and the rest is shit like the servos and other hardware.. follow so far.
So you take your model, a light .25 glow is about 9oz, an airframe made of 1/2" balsa is probably well lets see i just weighed the lightest sheet of 1/4" i had and it was 1.75oz so lest saythat the 1/2 are 3oz how many sheets? lets say 5 thats 15oz just airframe then servos at least 1.5oz, battery small nimh 2oz tank other hardware 4oz so you got lets say and even 30oz which is probably low now 30/3 is 10oz/sq'
for a small sport model this is not to bad but for a 3D model of this size its not good, smaller models to be 3D need to be really light, your plane probably will fly but it will be a fast snappy bitch. 10oz/sq' is lots differnet then 4os/sq'
but hey you gota learn the hard way sometimes so please finish this thing, if your not too lazy, and lets hear how it flyes, and when you prove me wrong i will not be surprized because i've seen flying lawnmowers, so stop shitting yourself

Ok, i think that post was a good thing, and by the way the guys that run my LHS can fly 3D and have flown 3D competitevley so
I have stopped shitting my sefl now so Ill just get the money together and finsih the little SOB. If it does get fucked up, highly likey, ill just get one of Swanys Tacos and use the gear from this.

thats what i thought

crap
King of the double post
Look at it this way: I've seen a lot of planes fly. Some fly better than others, but very few won't fly at all.
So the way I see it, your plane should fall somewhere between "Won't Fly at All" and "Flys Very Good". Now where it lands on that scale is kinda subjective.
Hope this has helped :lol: :lol: :lol:

i figured out whats going on any time i hit the back botton it does a double
even though i dont hit submit 2x
Uh Swany, Im not tugging your chain, Im thinking it will fall into the flies like shit catergory or between the flies average catergory.
I am well aware that it will have huge ass wing loading but I just want a cheap little dont care about plane I can have some fun with, thats why its an experiment.
Thoughts on my next profile, a Taco once this things dead and either a Katand from OMP, a Sportsamn Aviation Madddog or a Giles from TT as a plane for my .52, wadda ya reckon???
Im back to shtittin myself on this little one to

Gocha..... But I still say It's worth your time and trouble to do a build up wing... Not that hard and it will make your "experiment" fly sooo much better.... but give it a shot and let us know...
Of those planes you mentioned... The Katana is probably the next best ship out there... The Taco is good if you're looking for something .25 sized...
Then again.... You could wait another two weeks and get a MoJo...
