Video? The PZ15090 and PZ15091 have been out for about a year now. The rotationals are what you see on the FMS models. So these have been in use for a while. They are just changing the trunnion.

Wow so cool

PingZheng is the manufacturer

And if you want them at a better price or even just a better look at the actual dimensions PW-RC has them for less;

5mm struts, 14mm wide trunnion, 3.5kg load rating
PZ15091 Metal Trunnion Large
PZ15091 Rotating Nylon Trunnion Pair Large
PZ15091 Original Nylon Trunnion Large

3mm strut, 12mm wide trunnion, 2.5kg load rating
PZ15090 Metal Trunnion Regular
PZ15090 Rotating Nylon Trunnion Pair Regular
PZ15090 Original Nylon Trunnion Regular

3mm strut, 10mm wide trunnion, 1.5kg load rating
PZ15094 Single Nylon Trunnion Mini
PZ15094 Rotating Nylon Trunnion Pair Mini Note the pivot shaft is all nylon not alloy on the mini rotational retract.

Or try Hobby King, Hobby Partz, RCLanders, RC-Castle, FMS, Freewing....
These are all the same Ping Zheng retracts that have been out for a while.

Ya I use all of the line up but for some reason a few people complain about them. The 25-46 Eflite rotational appear very good for those who routinely carrier land compared to the PZ rotational solution. Down side is they are heavier and cost 8 times more. and thats without the struts.

the problem with many of these is that they only handle 8 lb models or so.

That's why I am looking forward to the Wingspan retracts. I have been talking to them to speed 'em up a little.... 6 or 7 second retraction time instead of 12 seconds.

Sorry; had to double check which forum I was in. Could you point me to a 8 lb foamy. Thats what these were designed for under 8lbs. Above this you have to go metal Eflite, Lado and who ever else. All very expensive. How some are breaking something rated to 7.5 lbs with a 5 lb model makes me wonder what they are flying off of. And I fly off grass.

Im not sure if you are talking to me Maxthrottle but if you are, I am not referring to a foamy.

This is a discussion about ALL electric retracts..not just the foamy stuff. Yes, my Kfir is going to weigh somewhere around 15-18 lbs...

If you weren't talking to me, then I apologize.

MAX is referring to the fact that this thread is in the Foamy EDF forum...

Thanks Chalmrast;
JJ No offense intended. There are a few threads in each section on Retracts. The Warbirds, Composites, Foam etc.
For foam, if an $8 retract can generally do the job, then the heavy stuff is over kill and reduces performance because of weight. The latest 6lb A-1 and Corsair may very well need something like the 25-46 100 for regular field use since landings tend to be rough, tipping over and have left roll tendancies. But those are 1.6 meter wings spans so they can handle them better than the smaller EDFs presently available.

I like the actuator cylinder replacement because there are already proven light metal retract setups out there. But for the price I won't be putting it on foam. Composites may be but they are already heavy so the hope is improvements to the cheap simple light PZ retracts to accommodate this segment.

DOH!

My most sincere apology. I did not realize I was in the foamy EDF section. Wow....I'm an idiot.

Oh well, some good info on here anyhow..

Life begins at transition
I've got a foamy that's pushing 8lbs... A flyfly Mirage, with the 15091's as the mains.
The FF mig could easily exceed that.

And I'm another who doesn't restrict the use of these to foamies - they'll do nicely in a 70mm crunchy too

Have you tried the metal trunnion versions yet. Still waiting on mine to arrive.
Like the ChangeSuns I think the metal Trunnion will improve the life cycle and torque rating to handle hotter EDF landings.

Hopefully they made the block that transitions over the worm gear thick as well.
