One Legged T-Rex (OLTR)

[gotzskillz]

I just figured you would have posted on here. I saw the last thread earlier today but it was talking about your front grip lpr's so I was confused.

I posted the other thread to get peoples attention. If you had read the first post in the thread there would have been no confusion.

I completed and tested my first Cougar M86 build, it works great. No way to run the hidden reg on a retro fit though. Should be plenty of room if the frame had a build in mounting tab though.

Luke, I took a look at the render drawing of this frame after seeing how you created the mounting tab for the OLTR.

Could you maybe make the mounting tab "adapter" an L-shaped part to hang off one or both of the top two open holes in the mounting plate, secured by a single screw in the top most completely closed hole? It would put the mounting tab adapter no further down the frame than roughly the barb fitting on the OLTR (I think?) and get that bottom most chunk of metal on the adapter out of the way to get the sleeper LPR enough room to fit? (Would maybe even shave a few grams off the weight of the adapter? )

[luke]

I'm sure there are other ways to do it, it's all about cost and what people are willing to pay, this is the cheapest solution and easiest to machine.

To put it bluntly, retro fitting sucks. I would rater just machine a new frame designed with a proper fit.

Looks great, can't wait to shoot it with the warp!

I got my gun back today and couldn't resist airing it up with my almost empty tank. I only had about 700psi left but I still put it on and let it rip. All I can say is that I love it. I filled my tanks on my way to work so tomorrow morning before work I should be able to really shoot it and take a video.

Agreed, but doing the best that can be done with existing frames just means more OLTRs out in the wild. Particularly, as you have said yourself, existing inventory(ies) must be sold through before "a new frame designed with a proper fit" can (will) be made. In the case of frames other than yours (which can/might eventually get the proper redesign), the retrofit might be the only solution ever. If that is the case, a little extra time up front could pay off with more volume in units sold over the long haul.

I guess it comes down to how many OLTRs you're looking to sell individually versus using the OLTR as more of a special value-add to your own stuff. No right or wrong answer; just choices, like most things in life.

Of course, with the KAM M86 runs being as small as they are (and fairly frequent as of late), making a "rev.2" with a mounting tab machined in might be a not so painful endeavor from a design-production-sales perspective once the OLTR is finalized.

Barkingspyder your in mail box is full.

To answer your question, the trigger pin is a non machined part. It's a standard 1/8" dowel pin, 3/4" long. It just slides into the front of the OLTR no problem tuning it to your preference.

Okay luke... just damn. Just got mine aired up, blew my expectations away.

[luke]

Thanks guys!

I'm curious to hear any feedback comparisons between the T-Rex and the MPA3/MSV2 builds if anyone has used both. I didn't have a bench mark to compare to when I designed this, so I really have no clue where it stands in that reguard.

>>> OK, so right now I'm not specifically charging for the mounting tab, but if I could presale 25 OLTR's and 25 installs in the M86 and customers were willing to pay for a more complex mount (more difficult to machine) that made allowances for the hidden reg do you suppose I could fill an order? <<<

I air'd up my m90 w/mpa3 & msv2 to com pair the trigger pulls with your new OLTR you sent back to me. Love both like a father loves his children, each for different reasons. The OLTR seems crisper and clean with trigger pull. The magnet pull really makes it snappy. The mpa3/msv2 I was able to actuate in quicker cycles, although I have that one dialed in pretty well with the combination of trigger stops and rod length. Both have a distinct sound unique to its own. Love playing around with it thus far, hoping to fine tune trigger pull travel.

Thanks Luke, worth every penny!

The T-Rex's performance is directly related to the AGD valve you're running. Of the markers I tested everyones setup was different. Oddly enough I tested a classic valve that tested as one of the better setups. On some of the markers that felt a little lagging I installed one of my ReTro valves and the performance increased significantly.

So a good test would be using the same valve to compare the two setups.

Also, in addition to your trigger stop adjustments, you can play with the LPR input pressure, lowering it will speed up the trigger...

Here is my opinion thus far, I'll add more to it after I shoot it more and play around with tuning.

First I'll start with a few pictures and a little explanation of them.

Originally I had sent in an Emag ASA manifold and a LPR but after a few PMs I bought a LPR-FG. I didn't know it but I had the prototype Mini Vert Frame, which Luke had originally milled with the P1 that you can see in the front of the trigger guard.



Luke pointed out that I had the protype frame and asked if I minded getting the prototype OLTR. He explained that it was exactly the same except it was marked differently, with the same P1



When I bought the LRP-FG I asked if he still had the prototype figuring I might as well have a fully matched prototype set if possible. Luke said he did, it also has the P1 marking.



Air channel milling in rail





The trigger pull is very short and snappy, I'll say it is electro short but slightly heavier. I haven't adjusted the LPR at all to try to lighten the trigger pull so it is possible I can make it lighter if I decide to. Luke did tell me that he wasn't going to performance tune people's markers, which I agree with. Everybody likes something different and I think half the fun is tuning it to get it just how you like it.

I think I will end up getting a different trigger as I find it hard to walk the trigger that is on there but that is a personal thing. I can't really walk a trigger anyways so it may just be me. I'm going to shoot it more tomorrow and if I have time start to tune it a little.
