Trex 450 X Tail Drive Gear Help
Hi
Another question i hope someone can help me with is the Tail drive gear for the Trex 450 x, i was flying it the otherday and luckly i had just landed it, when i tried to take off again i found that the tail wasnt turning i then noticed that the top plastic tail pulley gear had come lose a common fault with these heli's i found out
I purchased an upgrade metal tail gear but when i put it on the tail would'nt hold, i then checked the number of teeth on each and found that the first one has 11T on top and 22T on bottom and the upgrade has same on top but 25T on bottom so if im correct this will make the tail spin slower !
i have looked around and cant find the correct sized tail pulley i.e 11T by 22T even the Align part is now 11T x 25T and dont do the part no that is in my 450 X manual
As this heli was one of the first trex's to come out it has the slow 2800kv motor on it i thought if i upgrade the motor to the faster 3500kv so like the XL and SE version's then the tail should hold shouldnt it ?? as the tail will be spinning faster again
The main gears are the same as XL,SE versions i.e top large gear is 150T and autogyro gear is 106T so it should work if i put in faster motor !
could someone please help to confirm this as i dont want to payout for a new motor if it still is'nt going to work
many thanks for you help
