The weakest link for the GLA has been the servo saver, many run without one, and just the alu servo horn. It works, until it doesnt.
Is that an issue that persisted into the v2.1 or is that the issue that they tried to correct by updating the servo mount and servo saver? I'd also be curious if clubs bump up the wheelbase from 98mm to 102mm to allow this kit, as far as I know, the only way you'd be able to run it with the most common rules would be as an open class and not every club has the interest or the time to run open.
