Thank you so much for the info!! Was starting to think nobody was gonna respond to my post. So is this a .50 size heli? I bought a spectrum DX7 on eBay for a really good price. Now I just need to find someone or some info on how to set it up so I can fly. I know there is a lot of settings and I am not very knowledgable (yet) on how to set it all up. I am very familiar with nitro engines as I have been running large scale nitro trucks for about 18 years so tuning is not an issue for me. If you have any suggestions on setting up the DX7 I'm all ears. Again thanks for the info you have already given me!!
