I have a used nice, well built Geraghty 31" wood tunnel with a K&B 7.5 Pro w/Prather 235 stainless prop combo that I have not run. It has an offset center section by 1.0cm and different size stumble blocks on each side. The corners of the sponsons are nice and sharp. I was wondering if anyone has any info on this tunnel and ever seen one run? Is it fast or stable for a 7.5 class? I was thinking about getting a Bandit 33 in carbon or HTB for a 7.5, would that be a better avenue? Thanks for any info in advance.
