Here I go again with this Av I just can't help to keep''TWEAKING'' on LOL! All I did this time was to get rid of the flaps and made the ailerons longer length wise as I did before with the E-Flite UMX TT Evo V4 Av but now with the tail feathers of the E-Flite UMX Timber X which means now doing ''Knife Edge Spins'' are now very easy and now doing ''Hovers'' with the longer Ailerons and with the tail of the E-Flite UMX Timber X are also very easy you can now actually stop it from rolling on you while you're in a hover. All&all I hope you all have a whole lotta fun with this one as I am?
