Thanks mrasmm for breaking the ice and thanks Erik & Ralph for your follow-throughs! Collecting and using the proper tools to set-up, trim & fix (after crashing) are among the most important aspects of maintaining helis not to mention choosing the right heli to fits one's flying preference/s and budget. I started this thread to consolidate more info/feedback that can be contributed and gathered, if possible, and be useful to anyone who finds it so. Though there may be other similar threads or topics, it might still be noteworthy to start or reiterate one to emphasize its importance especially to the novice or uninitiated. Need not I say more as I'm still scouring the net for more info, I'll post 'em back (maybe some w/ questions & clarifications as to the proper dimensions and usage) Again, thanks in advance to those who have and will contribute for the benefit of all...and make heli flying as easier as it is enjoyable...
