Skyline, great job on the listings. I have both E-Flite and Lander, fly off of grass and have had zero problems with either. What I have trouble with is a finding sources for a good set of scale looking suspension struts (have the Lander ones in my Hunter, but -----!). I see these models with great looking wheels/struts (I am talking 70 and 90 mm models here) yet cannot find a good buy source. Have you by chance put together a list of these essential "accessories".

Freewing Electric Retract

Freewing electric Retracts (See pitcure Sample below).
Weight per retract w/o strut: 40g (1.4oz)
Height bottom of mount to top: 24mm (.95")
Width of Retract: 18mm (0.71")
Length: 67mm (2.64")
Strut Mount Rod Dia: 4mm

Mount Holes;
Width:29mm (1.14")
Length: 24mm (.95")

Already available via RC-Castle or Hobby lobby.

Opinions:
These appear to be a unique retract different from RCLanders and Eflite.
The design is like RCLanders in that the strut rod is mounted and locked in place via two grub screws thru the brass alloy trunnion axle. Also the motor, gear, electrics and overall size is the same.

Freewing improved on the Trunnion design, a larger metal lock block and thinker heavier worm gear.

The Freewing Trunnion (almost identical to the RCLander) has been improved on in that in the down and locked position there is a flat surface on the tip of the trunnion that rests on top of the metal lock block (which on the Freewing is made of thinker metal). On the RCLander the thin lock block was designed to push the sharp pointed trunnion tip and hold it; it was not designed to lock the trunnion in place other than by the worm gear.
The Freewing I find is superior in that even if there is a failure the trunnion can not rotate because the metal block holds it in place and can not move since the worm gear hold the block in place.
The Lander the Trunnion slipped off the tip of the thinner metal block.

The Lander is distinguishable by it brass mount hole option to be used to mount the retract or by bolting the retract to a mount plate made of metal or plastic. These plates can be mounted either from the top or the bottom.
The Freewing mounts and retract body are one piece and can only be mounted conventionally from the bottom.

Based on observations of Eflite 15-25 with the 4mm strut rod (though the Eflite trunnion is of the similar design to the Freewing but is wider) and the fact that both Eflite and RCLanders rate there at 3.5kg or 7.5lbs, these being of similar construction will likely rate the same.

It increase the load range heavier 5mm struts could be accommodated with a 1mm sleeve. The Trunnion axle is 6mm thus drilling it out to fit a 5mm rod may weaken the strength of the metal axle mount.

Cheers.

These are a good mid range 4.7Kg or 10lb PZ 514 (RCLander) Etracts.
Don't let the $8.00 price tag fool you. These are the heavy version of the PZ 312s sold as RCLanders. Of similar design the worm gear and trunnion are heavier.

Working voltage: 4.8~6V
Angle limit: 90 degree when retracted
Operating temp: -10~50C
Dimensions: 73.5x44x28mm
Weight: 54g
Shaft size: 5mm
Not suitable for a plane heavier than 4.7kg

PZ 514

Those are the PZ514 AKA PingZheng PZ-15091.
Look forward to adding your comments. Some who like the Eflites infer that because they are only $8 they are cheap and is getting by their QC because the stop sensors had been broken on some. However, other have had no issues. What weight class or model do you plan on testing them on?

Here is a set of nice rotating retracts for a 50" wing span F4U Corsair
I think they will come down a little bit in price once more vendors start carrying them which is what I am waiting for

Looks like the E-Flite retracts, nothing new...and the price is quite high, considering you get these retracts for 180dollars.

Windrider or the two links at the bottom "Strut your stuff" are the only one I know that has an assortment and they appear to be bigger so no I haven't where they are coming from yet, Sorry.

Neversommer.
They do look like the eflight ones but if you take a close look at the photo they are clearly etched 'fantastic jets.de' which made me wonder, as for pricing well best price I can find for the EFlight trike set is $185 = 141 euros plus 32euros for shipping so if you take into account,taxes and currency exchange rates I don't think you will be far out costwise and they appear to be in short supply I could only find one set for sale on ebay I will contact F-Jets tomorrow

Which one in particular.

I'm not promoting any particular vendor. Who ever has the stock item with good illustrations I added the link to the product within their site.

Philips page had been down so I didn't use it initially. But that reminds me he does move the FMS door sequencer. I can add that.

The spec says they're for 5mm struts. That's close to 3/16". If you meant scale struts, I haven't thought that far. I may use the fixed-gear struts that came with the model after cutting them off at the top.

Did you have anything in mind?

Not familiar with the model to make a recommendation but I am interested in strut suppliers.
RCSkylite, Smartmodel and Windrider are the first sources that come to mind.
