How do I remove the Spinner from my Sportavia

Post  BrownRobin on Sun Jan 25, 2015 5:02 pm

I recently purchased a New in Box gas powered Sportavia (from ebay).

One of the tips of the black plastic propeller is broken off and so I am trying to replace the propeller with a new COX one.

But, I am having a hard time trying to figure out how I remove the white plastic spinner.

I tried pulling on the spinner thinking it was the snap-on type but it won't budge.

So, how the heck do I remove the spinner?

We went through many Sportavia's back in the 1980's and I STILL remember how tightly those spinners locked on! I don't know it they were used on other planes, but they seemed to be on all of our foam gliders.

Try hitting it with some heat, then starting to pull on one side, working in a circle to see if it pops off. It was just as much of a pain to put the thing back on, but I don't think we ever lost one in flight!

Good Luck and Good Find !!!

Revised comment on my Sportavia donor engine from a friend. I pushed hard on the spinner, it made a loud SNAP!, now the bugger is hard to take off! I reached from behind, and pulled hard, it came off with a really strong tug! Shocked

Spinner prop nut looks like this:

If you accidently destroy it, Cox International Canada does have replacement spinners. Compared with my donor engine 1.25" dia. spinner, they are 1/10" smaller in diameter at 1.15", but should work still. That is provisional of course if your intentions are to fly it versus keeping as a collector. This item however is not a 100% match due to size and prop clearance cut outs.

I have been a forum member for only about a week or two and am really appreciating the support and information. You guys are great!

I pulled on the spinner as hard as I could and it popped off. The good news is that I have replaced the old prop with a shiny new one. The bad news is that I broke the spinner. No big deal as I kind of expected it would happen. So, looks like I will be ordering a spinner from COX Canada.
