Prop quiz...............

Post  rsv1cox on Fri Jan 19, 2018 9:30 am

Cleaning out my flight box this morning and installing a new Enya #3 glow plug in the N-28's series 21 motor I noticed a couple of things.

First on the APC I saw the numbers 254 X 102.  Took me a moment to realize they were the metric equivalent of 10/4", senior moments coming more frequently.  Smile  



Then I pulled out this Tornado 6/3 prop marked "pusher".   A lefty, and the only one I have seen marked that way.  Put it on a Cox .049 start it backwards and you have a "puller", right?  



To make Ken happy, I will probably toss out all those nylons.  But they have come in handy when I have to drill out the hub hole to fit a specific engine for testing purposes.  

I don't think that McCoy .35 has ever been ran.  I should remove it and bench run it first but may just break it in in the air.....



Just rambling thoughts from a rambling man...... Smile

Bob.   The yellow 6x3 pusher is (most likely) from a Gilbert 7 pusher used on the wing thing.

Thanks Rod. Mystery solved. I thought I had seen one like it before.

I still often use the same yellow bendy props that i bought back in the early 1990's, great on a Cox model with  no wheels fitted , most of mine are pusher props I just run them the other way, I found it great when first using cox engines as they tended to always start backwards for me back then... most were fitted to cox engines i bought from swap meets, I now have reverse direction spring starters on the engines as i needed to put the reverse spring starters from product engines somewhere!
