I'm looking to get a .60 trainer kit. I already have a tower .61 engine. I want to build from a kit. I have built a kit before and very much enjoyed the building process. The only 1 I come across in stock anywhere is a Great Planes PT-60. Any other suggestions? I've read on here that some have used a Goldberg Tiger as their trainer.(Its in stock also) Is this a good option? I do plan on finding an instructor.
