We have had the most difficult time in our 230 s experience. Bought our first one December. Second flight and the stock tail rotor blew up. We looked for stock rotors for ever as they were out of stock. Decided to buy a second one....bad mistake! The second helicopter flew a handful of times until it landed abruptly due to a Blade Failure. This time it was the esc/tail motor failure. So, we went to LHS and bought new units...they never made it in the air. Smoked on the spool up. Called HH and they said send them in so, we sent the esc and motor in. Weeks later we rebuild and were on fire. Called HH and sent all electric parts in for evaluation. After two weeks they sent a new ar636 in lieu of the ar636a and new tail motor and esc. The new RX included programming cables. So we installed all the components and began to program the RX. Total brick. No lights, no sounds, not even recognized when plugged in to USB port. Tolerance is wearing thin. Not only has all of that happened but my faithful dx7s received the spectrum update and now it is a boat anchor. Not happy with the RX and really concerned about my TX. Currently it is all in a box on my kitchen counter waiting to get mailed to HH.
