not bad....I have a shell waiting for a power system...gonna use a DX5e and an AR 600 RX.....by comparison my wildcat has amples of power with it's stock 480 - 960 KV.....a 480 - 1020KV for this slightly smaller plane might make it too much of a rocket for my liking ... would be nice to see the 450 setup....I am very unsure as of yet of what to put in it....
