I am going to scratch build the bloody wonder. I haven't built any of the swapables so I don't know how much foam I will need. If anyone lives in the UK and has found a good setup that doesn't come from hobbyking because of shipping could you please comment on what and where you got the parts from. I already have a 4ch tx, rx and 3cell charger so I don't need those. If you have also found a place to find cheap foam could you also comment. Thank You!
