Vincent,
I hope you get them figured out. I would like to hear how you end up liking them. The guys from the UK, at the FIJR, had a couple and they were awesome. They had one on a YA Stingray and it hauled the mail. I think they said it did over 200 mph. I was suprised that the engine sounded like a large turbine and didnt exhibit some anoying whining. Another show stopper was Jasons BV F86 with Wren 54 power. WOW!!! Did you buy the prebuilt ones and where did you get them from? Arent they around 1500 for the kit and 2000 for the prebuilt?
Thanks
Scott
