Flywheel keeps coming loose
My flywheel has been coming loose the last two-three days at practice. I get about an hour of run time in and then at some point when I go to start the motor back up the flywheel is just spinning with the clutch.
any ideas or suggestions on how I can stop this from happening?

Red or blue locktite let sit a couple hrs. Use a piston stop and tighten hard.

Loctite channel locks on flywheel and tighten it good. Blue loctite works fine

Never use loctite, it is totally not needed and for sure never use anything else than blue on an RC car when needed.
There can be 3 things wrong.
1) you do not tighten the nut very well
2, there is something wrong with the cone.
3) you never pull the crankshaft out as much as possible and then move the cone against the front bearing. In this way the cone is locked up. If you do not there is a small gap behind the cone so the cone can move backwards and the whole system comes lose.
The cone where the flywheel is clamped on will clam itself in the flywheel due the taper and so clamp it self tight on the crankshaft
look from the side into the gap between the flywheel and and see if still a small edge of the cone is visible and see by pulling out the crankshaft the cone stay put against the front bearing.

As stated. I have never used lock-tire on a clutch nut. I know Adam Drake uses a mix of red and blue but over the past 35 years I have never used it as I haven’t needed it for a clutch nut. If properly tightened the collet will grab, if not then something is wrong as stated by Roelof. Not saying to not use it just that it isn’t necessary if everything is in order and not worn. The correct collet should be matched to the flywheel.

Use blue loctite, tighten the bejesus out of it. If that doesn't work, you need a new collet and/or flywheel.

Just went through 5 kit manuals. Associated x2, Mugen, Serpent and Tekno and only the later said use thread lock. If you prefer pics I can post them. I honestly have never used it and never will. It’s not needed imo but I did say that if felt needed then use it. SMH.

On this forum I only see crap advice's from you. No manual tells you to use red loctite and with the many cars I have build in my 40 years I only have seen to use loctite on grub screws. I do see people choosing the wrong solution for problems like installing an AVC for a bad driving car but again, that is no real solution.
