For the second week in a row, I have torn one of the uprights where the tie-rod attaches to it in the rear. Now, I will admit, it took some bad landings to do this but still. I see HPI has a set of 2 for $70 but that's rediculous. So, bottom line, has anyone had experience with some bullet proof uprights? As a side not, I am using the complete set of Lunsford turnbuckles and they have yet to pop out although I do reccomend using some lock nuts on all of them as the plastic uprights will cause them to back out some.
