thanks! i will have to get some smaller batteries, since i don't have enough foam for the bigger one, so thanks! also, what motor would be best for the larger one? I have a 5300 kv inrunner, a 540 size but short can, would that work for the 42inch one?

jetttrooper: that combo package is from Dynam and I have the "icanfly" RTF with this combo. The AUW minus the 2oz. 3s 1250mah lipo is 16.5 to 17.5oz. and it came with a GWS 9x5DD prop. So if you build light you should be ok.

That weight was for the Dynam "icanfly" RTF, not any of the BB's. I was just giving jettrooper an idea of what that motor combo would pull.

alright, looks like i will be starting the build in either a couple of a days or in a few weeks, all depends on some stuff, like if lowes has 1/4 inch foam still or if i'll have to cut some of my 1 inch stuff down to size.

insomaniac your birds looking good . With my first 52 i kept alot of paper on my foam aswell because i thought it helped make it strong , what a bad idea . my only saving grace was the fact i was way over powered . Your much better off to reiforce with tape or carbon or bamboo skewers .
Good luck with your maiden

I'll bet it will fly nicely too. Is that wing a KFm2? With a step on top?

Thanks!
The wings are KFm3 profile.

If you use that motor, you will have to use a gearbox, probably 4:1 ot maybe even 5:1. These gearboxes are not cheap. They are also unnecessary weight. Since outrunners are so cheap nowadays, not too many people bother with gearboxes.

Your original 5300kV inrunner will have you running a 3.25" diam propeller, which is no suitable for this plane. You can keep it for when you go into edf's.

ok, i guess i'll hang on to it, i got the wrong $20 motor from hobbyking for a car and shipping is as much as it would cost to return it, so outrunners are the best bet? ok, i'll keep it for something else than, i have a lot of 1 inch foam so i'll probable make something stupid like a overpowered airboat or something, who knows. so i will be starting my build in a few weeks, i can't get access to cut down some 1 inch foam to the correct size for now, so no building yet. i also need some supplies for it to, but that's not major.

i have another question, has anyone ever painted these with a lexan paint? i have some for cars that is left over, and i'm thinking if it won't eat the foam it might be a really good paint for foamies, since it's really flexible(it doesn't chip, it will flex with the lexan shells and foam if it works with it.)
