Since all the old geezer's on this forum dont wheelie you'll never get a straight
answer by asking that direct of a question!
I have found 15/41 gearing to work very well for getting the front end airborne!
1st gear is a no brainer...
2nd gear, well thats where a little technique helps. I like to get the r's in the powerband then roll off the throttle and back on real quick. A little bounce of the front end helps, and dont be afraid to pull on her. She's a heavy girl and requires a little finesse!
Now 3rd gear is a whole nother story... I prefer to remain silent on this subject as not to offend the RC hierarchy
