Question: My VMAR ARF model came with a very complete set of Hardware & Accessories. I have one item that I am not sure about. Its a plastic "tree" with 8 rings on it. They look like they are intended to be a spacer or collet. What are they for?

Answer: These are collets for adapting VMAR spinners to various crankshaft diameters. Most VMAR ARF's now come with metal spinners that have a brass collett and generally do not require the plastic collets. But there may be some modelers who need to adapt a spinner to their crankshaft so we have included the 8 plastic rings (collets) with some models. In most cases they will not be required.

Question: Does a spinner come with a VMAR ARF? Is the spinner plastic or metal?

Answer: With few exceptions (such as small electric and small glow engine ARF's) VMAR ARF's come with a spinner. Most of the lower price point products such as Trainers come with a good quality plastic spinner. Mid and higher end products and even some of the lower priced sport and fun fly products come with a VMAR metal spinner. Yes this is entirely metal. The back plate is either steel or aluminum and the cone is aluminum as is the mounting hardware with the exception of the steel center screw.

In the case of several of our Jets (prop), the metal spinner is sized and shaped for a scale look, for example the Mig21 has a pointed narrow spinner and the F4U Phantom has an elongated bullet like spinner.

Question: Has the VMAR plastic spinner been improved since it was first introduced in 1998?

Answer: Yes. In 1998-2000 the spinner did not have a good finsh and used Phillips head screws to retain the cone. In about 2000 (depending on size and color), we introduced hex head machine screws and redid all of the spinner molds to ensure a better fit and a cleaner finish.

As of 2005, these plastic spinners remain in use in our lower price point products including most VMAR Trainers.
