I have used several now and like them. Like anything else a few things to be careful of. I use the heat shrink around the cap. Not because I had an issue but just because it will prevent it. You must make sure the oring in the cap seats properly. If it goes in a tail dragger you need to remove the fill tube and place in one that goes to the rear. Other wise, perfect for the price
Weather has not made that possible yet. Not sure this weekend looks good either. Flying this winter has been rough. Should have the last two build vids up soon and the maiden still to come
That one is specifically from seagull models but you can pick up the same exact one from the Xcub from HH www.horizonhobby.com/product/aerotow-release-xcub-60cc/HAN526013.html
