well, for me may seem like a Cop-Out but i just all together stopped "Helping Here" in relaity not worth it.....???
i hate to make it sound bad...??? but like some have mentioned it's true 99.99999999999999% of the "ONES" that think they know something...??? "Do Not" and end up giving advice that can not help...??
"Hak" made a good example....
and in another example,in the end really you'll find a hard time finding bad equipment,so much has improved over the "Many Years" i have been doing this......
anyone remember the "Red-Cell" Ni-Cad's......
Then remember when the 1700 came out...!! just from then to now so much has changed,heck anyone remember when
"8-Track Tapes were Introduced"...??????....LOL i can.....LOL
kits,parts,electronics...the list goes on and on.....

and to the other part, Knowledge base....
but most concepts are the same...."Knowledge and Wisdom" still kinda go hand and hand......and most do not know how to carry that "Knowledge" in a Un-Biased manor to convey the "Wisdom" they have "LEARNED".......
i have tried....??? but some kids hiding behind a screen with a Paper routes or sitting in a Collage Dorm,that paints one or 2 bodies a week??
or races maybe once a Month?? and never tried or used any other "Equipment" "Sometimes" just do not Posses the "Humility" to understand some of us have been doing this as long as they have been "Alive", and have picked up a "Tip or 2" to help others....but they do not see that..and then Interject an "Opinion"
that sometimes are almost "Worthless" to the General Hobbist,
who has nothing better to do but drop posts after posts on anything and everything and knows "Nothing"

so myself i say hello from time to time maybe make a joke or 2 with friends from tracks "Localy"
but i just help at the tracks nowdays......
but helping with advice around "Here" with the 5 to 7 people Roaming around "Here" in these forums pretty much "Slamming" others doesnt make it worth it.....
no doesnt chase me off.....??? but Misery Loves Company,and i like to hang out with the Cheerfull ones....

and True what was said if i was thinking of picking up on this hobby
and i started reading here in these forums....???
i proabally think Twice?? i have to ask myself are these same
A-Holes going to be at a track i race at.....????
the more "Experianced" ones know they are not.....???
it's a Hand full of Yo-Yo's....heck we have 2 or 3 at our track alone
there usually "Dissmissed" no one pays attention to them anyways....??
but here, it can reach out to "ALLOT" many might take this as a Base in Fact? and never know the difference....?????

same for myself,i am a painter by "Trade"
been at since 79' and my thing is there is no such thing as a "Stupid Question" when people ask me a Question on painting there real car or truck Helmet or R/C car... i have heard a Zillion times before
i treat it like i heard the first time.....
with "Respect that there Asking the Question" and they would like to "Learn" and not be Humiliated..........
i can remember "Where I Came From".....

but some r/c hobbiest have a attitude like everyone else is "Stupid"

i personally would like to help more....!!!! and i race and i do "Well"
not the best driver in the world....LOL but i have fun...
but what i have learned in "Experiance" i like to pass on......
