Thanks "Skill". However, would you know if maybe the PRO4 dogbones will work on the Cyclone? I can get several pro4 bones from LHS, and don't want to spend the money unnecerarily. I have heard that the FT TC4 dogbones also fit on the cyclone, and both the PRO4 and Tc4 are carried by Local shops. The week end is comming, and I need a quick solution; no-one carries or races a HB Cyclone in my area, so no-one's got spares, which means I'll have to sit out and wait till mid next week untill I get the order shipped to me from speedtech or precisionrc(however if the pro4 or tc4 fit, then I can race this weekend, since local hobby shops have them). However, need some one to please confirm if infact the PRO 4 can fit or the FT TC4, or maybe another kind...PLEASE HELP!!!
