Hi John,
Those props look very much like the JFX and XOAR wood props for electric. I've used the XOAR props and they work very well, so I reckon those props will be just fine. It is a pity about the lack of pusher props in the range but pusher props are not always necessary if the model is trimmed properly and has no funnies in the hourglass. Just look at how many of the top competitors are using tractor props. The pusher is a nice to have sort of thing and if I had the option I would prefer to use one, but as I say, it's not the be-all and end-all. Please post your results after you've tested those props. Thanks.
