Wobble on main gar !!


New Member
Hi Guys ... I'm just wondering if this wobble on the main gear of HK 450 is normal or is their a way of correcting it Or do I replace it.
I have checked the gears itself which is relatively straight , then I checked the bearing and its not straight in length . Is this normal or ?

Unfortunately the main gears supplied with the hk 450 are not to true and can cause major problems. Like Slobberdog said it is best to replace them with something better.
You will probably find you will have to replace also the tail unit they usually become extremely sloppy so also best to upgrade. Good luck with the flying
