You only seen so much of the efforts to install the Sierra retracts, it's a lot more detailed then you think. Obviously doable but still a lot of efforts. I made the templates to do it again which is half the battle. I'll be doing it again from the looks of things..

Manfred; I posted this very question and sent an E-Mail to Customer Support at Robart last week, and I have not gottten a reply, I also have NIB Set of FW190 Pnuematic retracts that I would like to upgrade as well, I'm beginning to think that Joe and Robarts would rather avoid this because if they upgrade one set they will have to upgrade a bunch,I'd be willing to pay for an Upgrade, something that I wish they would consider.
When we work with a manufacturing to spec a landing gear, we provide physical units for testing in the kit. This gear was tested thoroughly by multiple pilots and in multiple kits. There was never a concern of parts bending under normal use. As many of you are aware, a landing gear is only as strong as its weakest component (Chain and the weakest link comparison). If we make the gear indestructible, the entire gear will be ripped out of your wings, causing much more damage. Those people re-enforcing their gear now run the risk of shock loads being transferred to the mounting rails and who knows what else.. If people are interested, I can post the parts required and their cost tomorrow when I am back in the office.

Have a look at time 0:41 here; No damage to gear or wing;
( Except one of the gear links was torn apart; Replaced with a steel link now. an upgrade from Sierra)

...could soooo easily have dug a wing-tip in and cart-wheeled on you

We are not avoiding the issue. If someone wants to upgrade their gear with additional components, we are selling the parts to do so and answered any questions as best we can. This "Upgrade" was spec'd and tested by a customer and never developed here at Robart. We will not be changing future gear either.

Appreciate the reply, I am interested in the parts, I am a little bit confused though; you stated that "no changes will be made in future gear" my question is that in an earlier post you said the following "The electric trunion is now CNC machined and uses set screws instead of the slit tube and clamp screw. These have offered much higher precision. As we use up stock of the standard pneumatic trunion, this electric trunion (double pins and set screws) will be used in both gear"; is this a 'change' for future Gear or just 'available upgrades'? I am interested in this change/upgrade and does it use double cam blocks, one on either side of the Strut; anyways looking forward to your posting of the parts required for an upgrade, and I agree with you fully that the Gear is designed to act as the weakest link in abnormal operating conditions to save more extensive damage to the wing, it's just that some have stated and posted that the gear failed under normal or less than extensive abnormal use.

Joe;

thanks for the pictures of your baffling. (fg57t) I have solved my overheating by using much the same method though I am still using the original cowl mounts. One question I have is; do you make allowances for fresh air to the air intake of the carb? I believe I am getting warm or possibly hot air into the the carb because the carb is pointed right where the air outlet for the cooling is. engine runs well but does have the occasional cutting out though never quitting.

A quick Servo Question; for this Plane, which is more important, Hi Speed Servo or Hi Torque Servo?; I am looking at either the Hitec HS625 Hi Speed with 94ozs at 6volts - VS - HS645 Hi Torque with 133ozs at 6volts; same price for either one, both types exceed the minimum suggested torque of 50oz-in; which way to go? It would seem that the way to go would be the Hi-Speed type, you get faster Action and it exceeds the Minimum, best of both? Right?
I use the hitec 5645mg in all my birds. just an fyi chief aircraft have them on sale for 38 bucks plus a additional discount code on the site.

Soooo....
Are there any plans available out there to build a nice set of retracts that will drop straight into a TF FW190?
I wanted to try the Robart electrics, but it all seems too hard to get down here in Aus.
And I'd go the Sierra's (despite the extra cost), but it sounds like a lot of work to get them to fit.
I just want to get some decent, strong retracts in this bloody thing - without all the rigmarole.
And I don't mind having a crack at making them (all or part of) myself...

I talked to Eric at Robart today on the phone. He said there are no trunion mods or upgrades being done on the FW-190 electric retracts. I told him about Joe and this thread so he went and asked somebody else at Robart and they confirmed there is no trunion upgrade being done. Eric said the only mod or upgrade that is being done is by the modelers by adding the second cam block.

Darn shame that someone seems to be posing as tech/customer support for robart.
Even bigger shame that it looks as though robart is going to ignore an obvious design flaw in such expensive retracts and leave it up to the customer to fix their shortcomings.
Seriously, how much can it really cost them to install an additional housing block to each unit?
