"I'm sorry to read about the covering issues. I've attached a link to abulletin that our R&D Department put together for tightening covering on ARF modes. The advice in the bulletin should help you address issues like this in the future. However, it appears that your covering may have gotten too hot and separated. At this point, I could send you some new covering to replace the covering on the model. If you would like that, please give us your address in India.

I have replied to this email asking them to directly send me a replacement lower wing as I dont intend to have a patch on my brand new airframe. Lets see what they answer
