That is fantastic! I wish I had the skills to build something like that!
If you have some video, and a youtube account, just shove the video on there, and then post the link here. I would LOVE to see that in the air, and taxiing etc. Beautiful, well done!
The CH-Ignitions will work fine, Adrien is a top bloke, and has been doing this for years. He might even be able to make a custom timing curve for you. Best you give him a call.
