Hey guys i found this link to the Plus 21-7BT last night if you are interested:

It looks like a 5T on steroids.
What do they mean by a grinded thread on the crank?
NP-1 sounds great about your PLus 21-5T.
I can't wait to get mine and put it in my Buggy.
I have an LSK that i've just run in which i will probably put into my truggy.

Sure is strange for Dinball as i have bought stuff from them before and they were good but the last 2 times the stuffed me around in the same way.
AMain Hobbies however are the fastest and best service along with Carolinas RC.
I usually get my parcels within 7-9 days from these 2 guys but not Dinball.
Anyway lets stoke up the Plus 21's i can't wait
