Retracts are pretty expensive if they are good. Take a look at BVM retracts for his scale jets.. they will set you back about 1k. Are they worth it? I guess that depends on what one considers value.

Darrells work is as good as there is in this industry. I have his retracts in some of my other planes and wouldn't heisitate to recommend them to any one.

I know it seems odd that the retracts cost as much as the kit.. but often so does the engine. Retracts are as difficult and sometimes even more so to make than engines.. We just appreciate the engines more

Hey Gents!

I have decided to run a Moki 2.10 with Pitts Exhaust and a 19x11 3 blade prop. I figured at 18-20 lbs and 3500 feet elevation, the larger Moki would be the ticket.

That Moki will haul the plane around great.. It's a very good engine

I can understand what you are saying. I was looking at a radial engine for this plane and saw a $800+ price tag on it.Sheesh. But it is a beauty.

I'm really debating on making this thing gas or electric. Not glow. WhenI told my wife the $400 plus price tag on the retracts themselves, Ithought she was going to slap me! What can I sell, that won't get me arrested?LOL. Hmmmmm

BobH, since you have a set of his retracts for your other planes, could you email me some pics? I'll also head over to his website too. Sierra.com?

T-28 Owners,

ESM T-28 Retracts and Struts are well on there way.
Main Struts are almost complete.

We have the plane put together so we can check to make sure the plane is setting level on the gear.
I just have to figure out the best retract and steering method for the Nose Strut.
We should have a few sets ready to go by early next week.

We have not looked at what to use for wheels and tires yet.
The T-28 Used a few different designs.

If you have a preference, let me know. But it would be best to use
a ESM or Dubro Tire to keep the price down.

I'll post a few photo's this weekend.

Regards,
Darrell

BTC,
I would do a search on RCU. There are many who have gone the route of the ESM gear. they end up having to buy sets of gear for the same plane. I bought a set for a KMP 110. I had them installed and they leaked air from the begining. I found that one of the cylinders was machined too deep and it leaked around the piston. I sent that one back and got a new one and they still leaked. I eneded up with the Sierra gear in the end...
So save some cash and get a good set to begin with....

To clarify.

Please note I do not know this info for a fact, but just by reading SGS's web site and taking common sized gear into consideration that he makes for other planes:

1.) What is included? Ask Darrell. I'm willing to bet a nose gear, and two mains. His air system (tank, tubes and valves) will run you about 85 bucks for the large tank set (that is what Meister Scale charges anyways). I will tell you 100% that the tank, airlines and valves for the ESM stuff will more than likely need to be replaced as I have had a set of ESM gear for the Bf 109 and the P-51 and both were total wastes of money.

2.) Materials being used... again ask Darrell, but most are aluminum upper strut with stainless steel lower struts. THe forks would probably be machined 6061-T6. I would guess the mains would be using a 5/8" pneumatic cylinder.

3.) Why is it priced that way? Because Darrell's shop is a small shop and he doesn't have the resources to have 1000 copies of said gears on the shelf. I'm willing to bet a good number of the parts, if not all of them are not just punched out, but probably hand machined.

4.) As for reviews of SGS's products... think about this, almost ALL the retracts used by the large scale builders come from one of two sources, Sierra Giant Scale or Shindin Machine. At Top Gun 2009, out of all the builders for the WW2 birds, I would say a good 60-70% of them were using SGS gear. He supports his stuff and when things are not right, he fixes it and continues to refine his gear. Which is a lot more than I can say about ESM.


If you want a cheap set of retracts that may or may not work, that looks average and not very much like the real thing, but save $100-$150 bucks, by all means go ESM.

If you want quality retracts that work reliably, that are tough enough to take a bad landing without bending, or snapping, save up the few extra bucks. It is worth it.


Here is an example, compare ESM's 109 gear to Sierras:

ESM (Cost as shown (from KMP): $275.00)


SGS (Cost as shown: $230.00)

Has anyone actually flown this plane or seen a video? I am very interested in the T-28 but would like to know something of its flight characteristics. I have a DLE-55 looking for a home.

Darrell,

No problem. It took me a year to save the money (behind the Wife's back) to get my Fw 190 1/4 scale retracts from you and I have nothing but good things to say about them. Plus you are good at giving Dino and PJ a hard time, which I enjoy quite a bit...

So yeah, I'll pimp your gear any chance I can get.


Builttocrash:

Nope, not personal at all. I had the unfortunate experience of buying a set of the ESM retracts directly from KMP and regret it. If I can help anyone avoid wasting the money that I did and turn them on to one of the folks who does a bang up job of making some damn fine scale retracts, I'll do it a million times if I can. Trust me, saving for his T-28 gear will be worth it.

Is the picture reversed? From the pictures I've found, the nose wheel is on the wrong side of the strut. Maybe its me?

Good Morning.

Is it possible to know the total weight of the model (all parts) out of the box?

Does it need a lot of weight on nose for balance?

Massimo.

Massimo, i don't have the answer in pounds, but i can tell you that it is [very very] light. due to the fiberglas fuse and lite build of the big wing. VERY LITE! hope that helps for now. don

Darrell,

Is the Trojan suppose to be sitting a little higher on the nose? I set my YAT-28E level and it jerked up hard after pulling on the elevator!

I lengthened the nose gear a 1/4" and she lifted off much nicer. Unless the ESM has more + incidence in the wing.

Just a thought, maybe I am wrong....others chime in!!

Mike,

Once we get some weight on the plane, the mains should start to compress
and bring the nose up.

Crash,
You are right, we have the nose fork on the wrong side on the Prototype.
Not a problem, the fork is reversable so we will make sure it's right before we ship any out.

I'll get a photo of the nose strut once I get it finished. The one on it now
is just to find the ride height. I have to make it a little bigger in diameter
and add a few more scale collars and such.

I agree. This plane will be a floater. Anything under 22 pound with this
much wing will be a nice plane. Just need a large enough engine for the
big loops.

Darrell

Darrell, FYI i have some model T-28 info to pass on to you and ALL for your review. when you have time guys, please review the following website: www.t-28-trojan.com i have been a member of this site for about three years. Sadly, some unknown Hackers have destroyed part [forum] of the site from it's founder "Dave F" many times. it is still 95% open for all to enjoy at this time. the site again is: www.t-28-trojan.com options to review on the site. T-28 History, Const Mod, painting, and lasty Finishbuilds shows Hal P's and Deans beautiful T-28's. thanks don
