Hi,
You mentioned Byron fan or turbax, not dynamax as the responders said.
We only recomend the Byron if you have one, the Dynamax, or Ramtech or our discontinued vector fan, do not use a .90 on a vector 80 or a .80 or .90 on a vector .65 Does not work and is dangerous.
I have tested a lot of fans and only the above can I guaantee will take of rough grass in less than 60 feet, you can get a free video showing this.
I love to see new jet modelers and have promoted all my competition but if you can not see them fly from a grass field like yours at least on video ask them to send you a video before you pute all the time it takes to build a jet.not to mention the money.
