Mitchell Howard Posted July 25, 2021 Share Posted July 25, 2021 I'm expecting delivery of a Max Thrust Ruckus foamie during the week - according to the **LINK**, the wing bolts look metallic and metric, but I want to replace with nylon thumb screws for speed of field assembly. Can someone advise the thread spec? I suspect there's also the undercarriage retaining bolts - if they're metallic too, can anyone say if they're self-tapping or also metric? I hear they rip out readily in less than ideal landings and I'd rather have the nylon shear than the fuselage. Quote Link to comment Share on other sites More sharing options...

Mitchell Howard Posted July 26, 2021 Author Share Posted July 26, 2021 Thanks Steve - this video does confirm the self tappers on the u/c, but for the wing, "two long ones for the front and one for the back" doesn't help! Might try to find a manual, sometimes they've got the thread spec shown to help identify the screw in a bag of many. Quote Link to comment Share on other sites More sharing options...
Colin Carpenter Posted July 26, 2021 Share Posted July 26, 2021 I suspect they are M4 , the same as the Riot. I changed for hex cap because the heads of the originals were Chinese cheese. They are also recessed into the plastic insert! Colin 1 Quote Link to comment Share on other sites More sharing options...
