Default RE: I saw a production set!

Hi Voyager, and all; We made it through Jeanne with little additional damage! Guess the first one got rid of all the "weak sisters"!! It was stronger than the previous one, but went through twice as fast! Got home from sons' place yesterday to no power. About 4:45 this AM, power came on, and we got up to turn things on. Kay made some eggs and coffee, and while eating, out they went again!! Came back on about an hour ago! So had to get online to check email. It will be a few weeks before I can get everything done and a price figured for my system. Incidentally, I also use a modified cam system. It's a good way to go. Darryl did it right!!! Will keep all posted on progress. Tomorrow will have to unpack and get shop up and running again. (HEY--didn't I just do that????) Lee Robinson. By the way, what kind of price is Darryl quoting? (Maybe I won't be able to buy that Lear!!)

I remember he had always quoted an expected price of $250. That may change with production but there is no current price available (that I know of).

I did not ask Darrell what the expected sale price will be when I was there yesterday. I was so excited to see the actual retracts, I just forgot...

When this thing first started, I too remember $250.00 being referenced.

Do you have any idea where you might be on price Lee?

I sure hope the Hurricanes have finally came to an end for you all in Fla. My thoughts and prayers are with all those that have lost so much.

Default My Gear Arrived today

My UPS man dropped off a package today addressed from Sierra Giant Scale. And I am please to say that it is my long awaited P-40 gear.
Let me be the first to say that this set of gear was worth the wait..... In my opinion the way that Darrell has designed and manufactured the rotating mechanism it will work flawlessly for many years. Now I have to hurry up and finish the OMP Yak 54 profile that is on the bench and get back to work on the P-40 so that I can try them out.
As you can see in the pictures I also ordered a set of his wheels which are also top notch..... Way to go Darrell.....

Good to hear, I guess I can reorder now. What was the total delivered price?

Don,
It was $250 plus $6.00 for the shipping. And they are worth every penny.

Correct me if I'm wrong, but those look like Corsair gear because the struts look short. P-40 struts are longer because the P-40 doesn't have the inverted gull bends in the wing.

I'm guessing the Robarts that they are replacing are one size fits all, too.

Remember, the P-40 wasn't swinging a 13 foot diameter prop so it didn't need the prop clearance.

Robart RoboStruts can be cut to different lengths. My point is that the Corsair struts are much shorter than the P-40 struts. The P-40 has a belly pan, so the wing is much higher up on the fuse, which means the struts are longer. The struts on the Corsair are mounted at the lowest point of the gull bends, which are lower than the fuse itself, so the struts are much shorter.

Just Plane Nuts,

Can you throw the gear on the P-40 plans and give us a warm fuzzy about the length?

I would like to know that also. I hope Sierra is making two different sets of gear, one set for the P-40 and one set for the F4U.

I originally had 3 sets on deposit for the Corsair, the P-40, and a Bridi Shrike Commander. I'd love to read what the compressed length is on these gears. heheheh

Hi Richard and all; But this leg length bit is a perfect example of why you can't trust your eyes looking at pictures! I'm sitting here looking at full-size dimensioned drawings of both the P-40 and Corsair struts. Ready for a shock?? The length (parked or taxiing) from upper pivot to axle, for the P-40, is 37.75" (that's INCHES!). For the Corsair, It's 6' 3.5"!!! The Corsair is a much larger plane than the P-40! By the way, that same dimension on a T-6 is 29"!!! Shocking, isn't it???!! Lee Robinson W. Palm Bch.

I have the prints put away because I have another project on the bench but they are 5 1/2 " from the mounting surface to the center of the axle. I ordered a small set of wheels for mine. The plans call for wheels sizes any where from 3 1/4" to 4" wheels.

Hi Dale, can you please provide some pictures of the rotation mechanism. It has always been the weak link to this type of gear.

Thanks

You can't realy see the rotating mechanism. From what I can tell there is a groove in the upper portion of the body and there is a cam that follows the groove. It looks very reliable.

Earlier today, I sent an email to sales@sierragiant.com to ask about the TF gear and it came back as "Message would exceed quota for <sales@sierragiant.com>"

Darrell, empty your email box!

Does he only do phone orders?

Hi Dale et al; I just saw your comment about the mechanism! It sounds exactly like the full size unit I designed and protoed about 4 years ago! I'll have to dig out my old drawings, and I had some pics also. At the time, I just didn't have time to pursue it. The little unit I'm working on uses a modified version of my original cam system! That's why I said in one of my comments that with a cam system, Darryl was on the right track! So the two of us can't be wrong! Right, Darryl? Small world! Lee Robinson

Lee, so how are your gear coming along? We still need a direct drop-in replacement for those Robart 615's.

Hi Richard L; I'm just getting cleaned up on house enough to get back to speed in the shop. Still have backlog of other orders to finish, but am doing a bit on gear in between the big stuff. It will probably be 3 or 4 weeks before I get the "pretty" version done. Have to get back with the CNC guy again; he had storm damage too, but not real bad. Has been closed for about 10 days. But we'll get there!! Lee

The Corsair is a much larger plane than the P-40!
Keep in mind the TF Corsair and TF P-40 are in different scale, with the Corsair being roughly 1/8th scale and the P-40 being around 1/7th scale. The struts might end up being the same length.

From my last conversation with Darrell he is also going to make a different mounting plate and this gear will also work in the Hanger 9 Corsair ARF. I am not sure if you will have to remove any covering and make any wing mods to make room for the air cylinder. There is plenty of room in the fuse for the tank and the controls. The gear does not have a tork link with it either which will also offer if you are looking to keep you warbird closer to scale.

I sent an email to SpringAir asking if they had some rotating retracts in the pipeline.

Here is what I got back:

Hi Don,

No it is not a rumor. We will soon have a prototype ready for testing in the Hangar 9 Corsair.

Regards to Alaska!!!

We have hopefully finished with four Hurricanes. Have you heard?

Regards,

At least they answer their email.
