"Got my son to assemble..as now older does not play with lego but loved it when he did, buying this for ateaching resource. Looked good but flew a couple of metres, more without pilot...Zane. Tried different things like removing capsule...too light, wouldn't even start up. Unstable, wobbly. Flew out side this morning and the part of the unit comes off... Maybe advertising it as auto pilot, as said lego man makes it too heavy. PS only created account to give feedback...what along unecessary process!"
