We have recently purchased a Skybolt and due to inexperience on type have had a couple of landings which has resulted in having to replace the tailwheel assembly.Unfortunately the new assembly has also suffered stress and the connecting rod has been bent slightly even though there have not been any heavy landings since it was fitted.We operate from a grass airfield and are wondering if this is a weak assembly and if there is a stronger replacement available.In view of the weight imposed on it the tailwheel looks very vulnerable to damage.
