I used some standard aluminum foil to wrap the nose weights in my Sierra 2.5 This is about 8 inches away from the receiver. Can this cause some type of receiver problem? (I use the foil to create a "form" and to keep the lead pieces in place, rest of nose is soft foam pieces and receiver battery pack). RCSE-List facilities provided by Model Airplane News.
