GWS prop adapters for UM planes: 4mm bore to 1.5mm propshaft
For those who are seeking more thrust and speed from UM planes that use the 8.5mm motor/gearbox with the 1.5mm propshaft (such as the PZ Sukhoi 26m, XP, P-51, 4-Site, T-28, and HobbyZone Champ), the GWS 5043 prop is a great choice. Along with the prop, an adapter is required to fit the 4mm hole in the prop to the 1.5mm propshaft. Of course, you want an adapter that spins true; but the weight of the adapter is also something to consider. If the plane is already on the nose-heavy side (which is the case for the Sukhoi 26m), or is is borderline (as is the case with the XP), the last thing you need is extra nose-weight at the far end of the fulcrum, as this can make it difficult or impossible to set the CG properly. If the plane has a wide CG adjustment range, adapter weight may be of minor concern. If the plane is already on the tail-heavy side (as is the case with the HZ Champ), a heavier adapter may be just what you need.
Here are a few choices. Other vendors may also carry the items below. I suggest that you shop around.
I'm using the spinner below on the Champ. It's heavier than some of the others, but my Champ was a tad tail-heavy anyway. You get two of each: 1.5, 2 & 2.3mm:
The spinners are available individually here: http://store.rcfunlab.com/ProductDet...SpnCp&CartID=1
Some people like these wooden inserts. They're very light - well under 0.1g. They may need to be glued into the prop hub:
I use the adapters below on my Sukhois. They're almost as light as the wood ones above, but they're tougher, and they're a nice, tight fit into the prop. You get two of each: 1mm, 0.047'', and 1.5mm:

Thank for all the info ! Very appreciated! I'm new to flying so if I understand well, I'll need the prop, of course, the adapters from microflight and the spinners. What would happen to a plane without the spinner ?

You're welcome! Glad I could be of help.
You only need the adapter or the spinner - not both. The adapter is much lighter than the spinner, but the spinner is sort of rubbery, so it adds a measure of protection in a nose-over. If I'm dealing with a plane that's already on the edge of being tail-heavy (Champ, F4U), I use the heavier push-on spinner/adapter. Otherwise, I use the lighter push-on adapter.
If you use the adapter, be sure to mount it so the flange is facing forward.

I can not seem to find the adapters to make the 5043 work on the Beast anywhere! Except for that plantranco site and they want almost 13$ for shipping.... I am not going to pay that much for something that could be mailed in an envelope.
