i think this topic will be useful for others..

i have problem with the horizontal balance, vertical no problemo slow wheelis but when start to make circle i drop it :( anyone knows some training for circle begginers?

Firs of all start doing circles. try to do a very big... schoose a VERY big parking lot or smt else. and when you can do big circle try to du smallest and smallest...

its hard dude... also its hard to explain... Main problem is what u willf all outside the circle if u give too much throttle and try to balance it put...

anly i can say is "practce makes it perfect"
train it... no matter now anoyying it gets... at least 1 hour per day... and im tellin ya that u will get the basics down with in 4-5 hours of training...

i found perfect place for practice.. is the easy way with stand up wheelies ? and i think maybe big part from the problem is that i dont have wheelybar on my nrg :/

The wheelibar is not a problem at all...I never had wheelibar on any of my scoots and Im not planing to have it on a bikes either...Heres one usefull tip I got from stunters when I had same problem learning circles... Concentrate only on half of circle not on full circle... Think about turn your gonna make.. Not on full circle...That way you will making turns and start to do cricles... But.. Practice makes it perfect...
