I have the dsr's with the 5mm shaft on them. Can the RC Lander trailing link style struts for the Mig 17 that have a 4mm hole in them be safely drilled out to work with the 5mm shaft?
I need to cobble something together to use in my FlyFly F-86.
I understand their could be a height problem using the Mig struts on the F-86 due to the main struts being too long because of the Migs mid wing design. I was thinking of using my Changesun servoless front retract with the stock FlyFly front strut to hopefully compensate for the height problem. Any ideas here?

I'll ref these by their model number.
As far as any can tell, the RCLanders are the HK PZ312 or 15090.
The trunnion axle that strut mounts thru are 6mm.
So I wouldn't do it if the model was over 5 lbs.
The plastic will still hold it in place be it would weaken it to the specs of the ChangeSun Trunnion.

If your model can handle 54g/Etract then order the PZ514 AKA 15091 from HK. They're only $13 ea last I checked. They are made for 5mm and are much stronger being the intended bigger model to the PZ312, rated to 7.5Kgs.
Some did do it but I have not heard reports of success.

These are the struts I am talking about, Max. Are we talking about the same thing here?

Your link goes to struts not retract. These struts are 4mm and are intended for the Full RCL metal retract. Depending on you weight its my guess that to drilling out an additional mm from the RCL PZ312s is not going to kill you if you do so accurately.

Make certain that you take the trunnion out of the retract to drill. The metal shavings will likely short the board if you don't remove them to drill.

Go over to the Warbird section and look at the FMS Corsair, P47 or Mustang threads. They have been using them.

On the other hand if I were you I'd order a set of the PZ514s (5mm retract for those struts) from Hobby King for $13 ea. spec'd to 7.5Kg or 16lbs. You may have to wait in line though. everyone is starting to realize that etract, plastic based at least is very over priced and now HK is getting tonnes of orders.

The tricycles $45
Full set $69.

I'd like to hear from anyone who has used these as a rotating retract...I want to possibly use them in a Corsair...F4U, not A7

David,
I have a full set of the change sun, imho in the stock plastic condition I would recomend to use the as rotating type. The reason is the plastic trunion grub screw that locks the strut inline strips out most of the time when used as inward folding messing up the wheel alignment every flight. As rotaters the fixtures and ball links keep the alignment accurate. The stock wire struts are 3mm, e-flight axles work nicely but need the screw replaced with grub screws not cap screws.
I sent a note to X-flight on getting a set of metal trunions and jack links to update the plastic fantastic set I have. As far as E-flight retract updates there is Larry in Orlando Fl that machines the parts for e-flight retract owners. He makes fans also

These photos may aid in this electric retract forum. When I get all
the photos posted, I'll make a list of all these struts with prices.
Any additions you guys may have are welcomed.

It's best to split up the photos in two posts, so here is Part 2.

Regarding the ChangeSun electrics.

Where can one get the parts necessary to make these rotating sets? HK had the retracts, but the parts to make 'em rotate do not come with the gear. And, of course, HK is backordered on those parts.

Anybody else out there have these parts?

Thannks much.

You should have gotten the extra linkages with each retract package......
Check with Ming Lou @ wind rider

Here's one from Hobby King. I just ordered a pair for a VQ C.205. Will report on 'em later.

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?
