동일 제품인것 같은데 6V 700mAh 배터리라는데 크기를 봐서는
1.2V * 5 으로 보이는데
1.5V * 4 로 구성을 해보니 모터 드라이버가 문제인지 모르겠지만
모터 두개를 동시 구동하면 속도가 느려지는게 눈에 띌정도로 보인다.
1 * Battery Charger, 1 * 6.0V 700mAh Battery

너무 크기도 했고 여름이라 냄새가 심하게 나기 시작해서 방생하기로 결정!
(실은 병아리 먹이로 주자니 차라리 보이지 않는데서 새한테 잡혀먹는게 나을거라고 보내기로 ㅠㅠ)

ht_capab 에서 HT40으로 되어있어서 에러가 나던데
일단은 conf 파일 예제에 있던 대로 HT40- 으로 하니 문제없이 작동하긴 한다.
| ht_capab=[HT40-][SHORT-GI-20][SHORT-GI-40] |

로그를 분석해보니 HT40이 문제가 아니었군
