No experience of the Bixler but was considering the same. The Bixler is actually a big (ok medium) bird, and you will probably have to go join a local club if you don't have a suitable field to fly it in. Alternatively have you had a look at the E-Flite UMX Micro Radian? It's probably small and innofensive enough to fly in an (empty) park.
I built a Flite-Test Versa, but I need to change the motor to something more powerful (it's a heavy one and didnt take off
. Must admit really enjoyed the build process, but it's sat unused since as the spare time I get to fly end up with the quad so not sure I'll be taking up another RC stream yet (FPV buggy's sound fun though!).
Have a look at some of the smaller Flite-Test foamboard trainers, I'm pretty sure they have the plans for a cub size plane which looks fun. It costs next to nothing to buy, you just need time and patience to build it but I built most of my versa in a weekend.
Is there a general RC thread on OCUK? Otherwise we should rename this one to Multirotor, Cars and Fixed Wing RC?
