i was having them tear down through the vent in the center supports. all wings do it in the same spot and i found that the losi did it quicker
thats not the reason i dont use them. all wings break over time.

i just dont like how soft they are. when a marshall is in a rush to get you back on the track and is holding you by the wing it nearly folds in half. so when they throw you back on the track the car flicks in the air when they try to throw you forward. its a problem i had when i first started. it used to do my head in. so i switched to a stonger wing and havent changed back since. ive been useing AE wings for over 2 years. they work for me. i dont mean to sound like im downing losi wings im sure they work great for everyone and they do last quite well. but personally i had trouble with them
