I was just at TRU and they had a HELIX made by Air Hogs. I have never seen this before, does anyone know anything about it. It uses a 3.7 lipo @ 300 mha.I wonder I could use this battery in my AA? I think the stock batt. is rated at 160 mha. Well it was to neat to pass up , I had to have it. Besides it was the only one they had and at $ 59.99 it was worth a try, I can always take it back. I went there looking for a Storm Launcher , NO LUCK, they had some type of land and air NO WATER R/C that seems to marketed at the SL. It also used a lipo battery but its rated at 7.2v and comes w/ charger.
