I guess that I will see ya at the field this weekend with a ready to fly TopCat?
We have to get practice on the events for the Bayou City Flyers/Fort Bend RC Fun Fly Challenge.

We are going to have a rally start event so get used to hand starting your motor.

We will also be doing the fly between the uprights like we did at their field last year.

I think that the third event we submit might be the drag race, so the 72 will be fine and the 50 will honk.

Take care Jim

PS overall weight is also important, not just CG.
