conclusions on umx radian (ultra micro) sailplane


http://www.e-fliterc.com/Products/De...#quickFeatures
i have been able to fly the plane several times, but not into thermals yet. still, i have reached the following conclusions:
1.-the plane flies superb. congrats to the designer(s). very stable and predictable.
the proportions are great, and with the AS3X gyros, it behaves like its big brother rad. absolutely amazing.
(i own a big rad, so i can tell you this).
2.-but it is important to consider that a micro is a micro. a very different kind of plane. 1st of all, the way you handle it: you don't feel it (41 grams). it is like as if it comes from another dimension. you have to re-think all-or you may break it.
3.-some want to make it so the wing can be removed for carrying it in its box, but for that, you have the option of dealing with 2 microscopic screws, or modding it for magnets. i rather keep the wing permanently attached.
4.- some propose to make all kinds of mod, but to me, adding any kind of weight will impair its performance. think about it before you try. just fly it as it is (i just added a hatch to protect the cell from dirt-but that weighs less than a gram).
5.- the plane handles wind as if were a big plane. eventually i tested in windy weather (see below), and you can see these comments all over the place, including videos, to confirm this.
6.-so, there is room for it, and for the big brother too. it's just that they belong to 2 very different worlds and you have to become accustomed to each 1.
it's being discussed here: https://www.rcgroups.com/forums/show....php?t=2089760
may 9:>>>>>an update: just came back from the field. it was not only windy, but turbulent.
it was the 1st time i flew it in this kind of weather.
it was shaking and bouncing, but all went well. flies like a 2 meters sailplane!
and i don't think i could be able to survive the ordeal without the gyros.
wonderful things they make.
and in the previous flights that i made in calm weather, it also behaved much better with the gyros.
