Thanks Ian. Did some engine tests in the model this weekend and taxi'd around a bit. Crikey has it got some grunt! Spool up of the turbine from idle is fairly quick but still going to take some getting used to after flying EDF for so long. Just need to make some adjustments to get CG, get the brakes working and install a drag chute if I get time...oh and program up for the DX18 when it comes in.
