Official Jammin CRT.5e Coming Soon?
 

Hi All,

I've been checking out the Jammin SCRT-10 lately. Glad it uses so many CRT.5 parts as I love these little trucks and its great to know parts are going to be around for a while.

Looking at the manual today I saw something that gave me hope we may see an official Jammin CRT.5e release soon?

Manual is here...
http://ofna.com/pdf/34975-Jammin-SCRT.pdf

If you look on page 4 at the plastic tree, part number 40946. Its the new battery tray, ESC and Rx mount parts. Marked with a cross, as not used for the SCRT10, is a chassis brace that suits the new ESC mount and looks about the right size for a CRT.5?

What do you think???

Hope the CRT.5 evolves to electric and lives forever! :yes:

Cheers

Excellent! Just received the parts from Nitrohouse.

The parts definitely fit. Whats more those extra parts from the 40946 Batt tray moulding are actually to fit the conversion directly to an Ofna CRT.5 Extended chassis with no drilling required!

Clever, BUT... it raises the whole battery by about 7mm which will adversely affect COG.

I was planning on mounting the batt tray straight to the chassis as per SCRT-10. There may be JUST enough room to drill the outside holes? see pics

The rear brace is indeed to fit the CRT.5. And the parts go together well for a tidy layout.

Hopefully Jammin will release it with a new chassis just a bit wider. And with mud guards!

Anyway, check out the pics. Parts are just sitting there for a rough fit at the moment.

So I'll think we'll soon see a CRT.5e from Jammin or maybe a conversion which is great as I really love the way it handles with the OFNA extended chassis and the stock wheels.

I'll keep posting pics as I get it together. (Still waiting on parts)

Cheers.

More Pics

And more

And a few more

Finally got it back together. Just waiting on the MMP now!

All went together smoothly. Just bolts together.

Mounted the battery tray on the chassis though. And also some Tekno mudgaurds.

I'll post some details soon.

Cheers.

More pics

and more

The Body is slightly 'toady' with the mudgaurds but overall it should work well. I won't cut the next body back so far in the front wheel arches.

Stuffed the paint up too. Was supposed to be green but was too heavy handed with the 'mist' of gold. :whistle:

Cheers

That looks cool!

You also made some very nice photos! :)

Thanks Byte!

Its amazing what a sheet of white card will do for photos :)

Can't wait to get it running!

Cheers :smile:

Awesome build!! I have some Q's:

You have a picture of that white card set-up?
Which mudguards are that? I also want some for my STe!
Where are you going to put the MMP?
What dimensions does that tray have and would it fit a regular STe chassis?

That Tekno motor just looks sexy in there. I too want to know about the mudguards.

Wow...that's got to be crazy expensive! The trend in my area is to pick up an SCRT10 kit and go the other way. Beside the chassis length, body & wheels, they are identical. In fact, I just moved all of my CRT.5 goodies (alum c-hubs, rear axle carrier, CVD's, shock towers, alum wheel hexes, etc.) to the SCRT10 kit and now have a bullet proof, fast and great performing SCT :)

Thanks Nard, Snellemin & Mas!

Pic attached of the photo setup. I always use a tripod too but also works well with flash. Find a place with good window light, set white balance to 'cloudy', select a small apeture (for good depth of field), and use a 2 second self timer.

Photography's another hobby of mine and the technical aspect is surprisingly simple once you get into it. Takes about 5 mins to setup.

Mudgaurds are Tekno RC's. Available from their store...
http://www.impaktrc.com/product_info...oducts_id=2868
or Nitrohouse have them too. Found them from people fitting them to their Hyper 9e's. Check how much your servo extends on the STe, don't know if it might hit the gaurd. worth a go I reckon.

The MMP will go on the plate behind the receiver box, between the battery and motor. Bit high COG but whatever. They've done a great job with wiring with the new parts. Particularly, the servo wire is kept away from the spur nicely and the ESC wire will go directly into the back of the receiver box. It'll only be battery and motor wires exposed.

I'm stumped at whether the tray will fit an STe??? Got me there!

I'm lovin the Tekno too. 'mmmmm... My precious' :tongue:
I got it from impact rc when they had em on sale for $99

And MAS the total retail cost for parts was US$50 (think it cost $42 or something). You can see the parts and prices on them in the first pic of the thread. I had slowly accumulated the rest already for my CRT.5... and yes that was expensive when it all adds up! :whistle:

Check out special-rc on ebay for parts as well. He doesn't have them listed but he can get them from Hong Nor. Cheaper than Nitrohouse too (except he had the motor mount at $35 for some reason?? May have been a mistake???)

Cheers!

Ahhh, that looks so clean, have to make it also !! I also use a tripod and selftimer most of the time :) Thanks for the tips!

My servo arm extents a bit more than yours, thanks for the usefull info, think I will give it a try!

Concerning the wiring, it's spotless indeed!!

Cheers Nard :)

Good luck with it mate!

What are the internal dimensions of the batt tray?

I saw the new conversion kit for the CRT .5 on Ebay tonight. It includes the same parts tree shown in the second post, but the motor mount is different. It is a 3-piece mount that attaches the motor to a rotating cam and uses that to adjust gear mesh. The listing said it was Ofna part number 40990, but when I searched online nothing came up.

http://cgi.ebay.com/OFNA-40990-Jammi...item45f30bb301

p.s. anyone has part number 21067?? I need the lower thingy of the shock that mounts onto the arm and the upper part that mounts to the shocktower / standoff. Can't find it anywhere, atleast not when shipping is less than the product itself...

ps. who of you is running 1/8 buggy rims and who likes it more than 1/10 ?

It's this part.
Jammin sells it as hopup for the SCRT10. If you get the SCRT10 from HongNor, it's the standard motor mount.

Ah this thing has been shelved for too long! Had a crazy start to the year.

Silent Bob the dimensions are roughly 26mm wide and 150mm long. Max height while still using the plastic cover over the top is 48mm but you can go higher if you remove it and use straps. Sorry for the delay getting back.

That new motor mount looks awesome! I had heaps of trouble setting the mesh with the forward facing motor mount screws, this looks easy as! Thanks for the links.

I cancelled my MMP order from tower back in march after being on back order for months. Just saw it in stock so its time to get this thing up and running.

Cheers All.

Thanks for those dimensions.

Nice truck and pics !! Really clean (maybe too much :whistle:).

I guess you're a drummer ? I see a Roland module on your last pic :yes:

CRT.5 Pro kits US$99!
 

Thanks Popoxx. The MMP should be here soon so the days of cleanliness are numbered :mdr:

And yes, me drum. I just finished a soundscape assignment for Uni that features my childhood role-model, Animal (the muppet). I'll post a link when I get round to getting it up on myspace.

Hey if anyone's interested it looks like OFNA are clearing out CRT.5 Pro kits for US$99!!! See here...

Wonder what's afoot???

Well my MMP has decided to see the world it seems. It was shipped on the 2nd June, left the States on the 5th and nothing has shown up in tracking since. Called Australia Post today and the last info they have is that it was put in a bag in ROMANIA (for F@#$'s sake!) a week ago! Tower said they don't want to hear about it until 45 days after shipping. That should give it time to sail the seven seas and cross every continent on the back of a friggin camel! (Which is probably where it is now).

Anyway in the mean time I was messing around with a Jconcepts Illuzion B44 body I had cut to fit the CRT.5 before the e-conversion parts came out. A bit too much material is removed to fit now it sits about 1/2 an inch higher. I think I'll get another and recut it, I've always wanted to convert it to a buggy and I think this is gonna work this time.

The body's just sitting on the front post (turned around and mounted on the back of the tower) So when fitted properly it'll be about 1/4 inch lower.

Well my MMP emailed me some postcards of its travels. Glad its enjoying its world tour. :yes:

Tower's super saver shipping may not be the quickest but its great value if you want your parts to see the world. :na:

Couldn't help myself.

And some more...

And a few more...

LOL that's hilarious. Hope he finds his way home soon enough!

Thanks Simplechamp. Couldn't help myself :mdr:

How's your CRT.5 build going?

Well looky what turned up :party:

I've been of the edge of the earth visiting my parents in the beef capital of Australia for the last week so I've only got to get it in the car and give it a quick spin.

Trying to go slow on it until I paint it but its so hard to take it easy! This is going to be one fun car to drive me thinks. Here's a quick crap vid of the first test run, nothing over 1/4 throttle… http://www.youtube.com/watch?v=PSMigLbkxrA

Just want to solder the ESC leads to the motor, paint it and its done :mdr:

It looks awesome :)

Still love those parts, it makes the car real clean and tidy!

Anxious to see what it will do full throttle.

I've run 2 packs through it so far and its a blast. Only onroad though at the moment. Trying not to kill the tires before I get it finished!

I didn't take into account tire ballooning when I did the gearing calculations as I didn't think it would matter. So from a top speed of 39.77 mph (63.88 km/h) @3.7 Volts/Cell which is what I aimed for, it goes to 58.38 mph (93.78 km/h) @ 4.2 Volts/Cell with ballooning! I don't think its going quite that fast but it gets along. I'll get someone to video it soon.

Its the first time I've balanced the wheels on it too and WOW! I put an unbalanced set on for the first test and it shook the car at 1/4 throttle. With the balanced wheels it'll sit solid on a stand at full throttle. Amazing difference.

I just ordered all the parts and will see how it works with the rc bro mount... i like the rcbro one cause it has 2 metal diff holders... ill have pics up when i get it...

I didn't use the stand-offs for the batter tray. I took it to work and drilled 3 holes on the corners. Despite not having the fourth corner tied down, it's pretty well secure.

Sorry to disappear! Been busy lately.

Anyway I've had this vid of the wheel balancing for ages and finally put it up on Youtube to share.

I ditched the other vid as it sucked :whistle:

looks good. Now time to do the big bore conversion.

Hmmmm... I really should, shouldn't I.

That's got me thinking now :smile:

=p it is worth it!
