As mentioned on a previews thread with the MB339 the new kid on the block with a 70mm first version here is the new presentation of the 90mm version that lots of people are waiting about I ordered mine all ready and I will be following up on my review when I receive my kit at witch is a piece of cake to build? In a 56” Wingspan with a Freewing 90mm E7229 with a 3.9 kilos of thrust more than enough for the under 4.00 kilos flying weight to begin with this little jet will be the only low cost jet to have fun with on a 6S 35 and up batteries! Check out at Passione3d.it will be in touch!
