    T-REX 700 3G LE built , HELP !

    Hello,

    I started my T-REX 700 3G LE (Nitro) built, when trying to disassemble the main rotor head to check for grease and thread lock , I couldn’t unscrew the bolts , I tried hard after heating the bolt for 20 seconds and the bolts seems like one piece with the feathering shaft , so , I finished by “tightening” the bolts hard and put it aside , in the users manual , it is indicated that the rotor head is already assembled by the factory but ask to check if the bolts are fixed with thread lock ,

    So , can I trust the factory assembly , did they apply enough grease on the bearings and so ,

    I appreciate your advice ,


    Best regards ,

    I have the e 700 and was able, with heat, to get it apart. It did have enough grease in it.

    Thanks for your post , Do you advise to try to disassemble it and check ? The thing is I tried so hard with heat , I'm afraid if I apply more force the bolts may strip
    Also I'd like to ask about the main gear assembly (with the one way bearing) is there a need to disassemble and apply grease to the one way bearing from the inside (from its outer side after getting it out of the assembly ?, or its enough to apply grease to its inner side without disassembling ?
    I appreciate any advice,
    Best regards,

    I would grease the one way bearing. Use a white or clear silicon grease, they are pickey what type grease you use.
