Hi Chris,
Welcome.
Right, your truck is fine and ok to race. However truck races for us are only me Thursday a month, next one being this coming Thursday 22nd. So your more than welcome to pop down and give it a run.
You can run your truck in a buggy heat on normal meetings.
We have a full day on the 25th of August as well.
27 on crystals is fine
Pop down, best way forward.
