I could never get over its horrid stall. Plus you add a breath of wind, and it just becomes ugly to fly. I wanted some sport flying, which it does very well in perfect conditions, but conditions are hardly ever perfect and it was just a hand full. I found myself not taking it out which defeats the purpose of having it.

I was debating converting a FF kit or scratch building a F3A style ship (built up not that profile foam stuff). The corsair just caught my eye.

PS: I have a perfect UMX Beast frame minus the battery hatch if you're interested in spare parts.

Hey Eclipse, great job on the conversion! I'm sure it'll be a winner.

quarter scale Lazy Bee, 4ch

my other baby. a 25% scale lazy bee. just shrunk down the plans and only put in what i needed. not sure of the AUW, but some where about the 30-40G mark. may be waay off.

4 channel, the ailerons DO help at this scale. i cant roll, but it does help a lot with the wind.

I'm wondering why it wont roll. I have two homemade foamie bees. One is 24" wingspan powered by a 20g brushless (its actually way overpowered). This thing rolls like crazy and it has no ailerons. The other is about 18" and has the AR6400 setup and brushed motor. This rolls as well but the roll is not very pretty. Again no ailerons on this one.

Whats the weight of those wheels you have on there.

Figured I'd throw in a couple of my own. The first is my micro stick. Its 16 wingspan. The wing is built with 3mm depron ribs, balsa leading edge and covered with 1mm depron. At just a little over an ounce with battery, even with the brushed setup shes wild, agile and responsive and yet shes sweet. Cut the throttle back and she becomes a pussycat. I'd love to go brushless on this one but dont have a motor small enough.

The second is somewhat experimental right now but I think I got it ironed out. I wanted something that was a simple build and be on the wild side. Its fashioned after the stick plane and its 20 wingspan and about 1.5 oz with battery. Initially I had a brushed setup on it (you can see where it used to be in the pics) but it left a little something to be desired (to make matters worse the AR6400 was going in to premature LVC) so I added a separate ESC and a 180 class brushless motor. Now it came alive. Its wild and responsive and even a little twitchy. Its cuts through the air and is faster than I expected. On my second flight with the brushless, the motor pulled out of the mount and damaged the windings. I do have a spare motor. I'll see how it go's next flight.

The size of the ailerons on his plane may be a clue.

yeah, that is my guess as well. i made them small so i wont roll and crash, i tend to to that kind of thing. the wheels/axel assemble weights in at 4 grams, and its pretty far down. the 6 gram battery sits there as well.
last night i removed the wing and move the brick forward. AUW is 33.5 grams, but i used a AR6400T, about 4.1g, compared to the 3.8 of the regular. used a 2 grams servo, the nav light system weighs 1 gram, mostly cuz i only had the heavy parts on hand.
no carbon fiber, push rods are bamboo.
making a box for it so i can put it in a backpack.

Here's one of my favorite things to do...
Make a model of an old Favorite that I built and crashed (after 3 hard stunting seasons) back in the early 90's. Pic of the original shows why my name is painted that way. The Original was a champion models, Stampe SV4B with an OS 90 FS. weighed 7 lbs. (!) and flew great!

The micro Stampe spans 22" and weighs 35g. three grams less than the t-28 I got the radio out of.
It flies great also, but in a much smaller area.

Micro Capricorn aka Flying W

I've started a separate thread but thought I should include my Micro Capricorn here too.

That was my first thought too but was not my intent. Best.
