RE: Anyone Own a RT-X 27?
I have been looking at the Axial .28 as I have read here of people running it. However, locally i can get a good deal on a HPI F4.6. Does anybody know if this motor will fit and if it is any good?

I hear ya about the motor. I gave up and installed an Axial .28
Many of us are running Axial .28 or higher, OS, LRP. Take your pick!
On another note has anyone else experienced a lot of cracks and breaks with their trucks? I gave mine a good going over and found many parts that have cracked or just broken. I havent hardly drove mine yet and I sure havent bashed it hard enough to have so many cracks. If I sent them all in I wouldnt have a truck left.
I also noticed my front right diff is leaking a small amount of oil. My brother's is leaking in the same spot on his RTX as well. Normal??

I have the K4.6 in one of my warheads. It's ok but drop down to a 14 clutch bell from Ofna. It will help with better take off. With this engine you don't have to worry about blowing your trans.You can use the roto start but will need to grind down the engine mount in two places.

Thanks OddsNends, the VW body is different but was fun to do for my first try at a body.
As for parts cracking well lets see, the front skid plate both corners that screw into the chassis, the front and rear diff covers, and a couple areas seem to have hairline cracks near screw points. I think they should give us 2 trucks when we buy these, one to drive and one for parts!
I am off to race my brother and some buddies tomorrow, will take some vid and post later on

RE: Anyone Own a RT-X 27?
Gee it has been awful quiet in here this weekend, hopefully all were out racing or bashing.
I was out at the Bardis Speedway with the other Bardis Bashers. Here is some video
http://www.youtube.com/watch?v=gHdXIWOLPgA
Grasshopper got home too late from work so he couldnt get out his buggy and Jason was off to a wedding. So my brother had his stock RTX out against my Axial RTX Bug. I have to say that his truck is fast once it heats up but he still struggles with high temps. The Buku pipe I installed has not been fully tuned but you can see in the video that it adds about 25% more power to the .28 Axial. I had to cut back on the throttle a lot because my steering servo horn was stripping and I was losing steering. I didnt realize it until I finally lost it into the rhubarb! I will be upgrading to an aluminum servo horn, I guess the 202oz steering servo I installed is a little stronger than I thought.

Hmmm.... those 109 buck do really pay off right!!!! Jjajajaj... i told you buku was the way to go!
Jay, be carefull... its better to strip servo horns than servo gears. If you are stripping the horn probably your steerign setup is not right, at some point it must binding or your end point is way too open. If you dont check on that an alu horn will hold but you will find yourself replacing servo gears... average 20 bucks the gear kit.
What radio are you using? Stock?

RE: Anyone Own a RT-X 27?
yes using stock radio, my Spectrum had a problem, sent it back and now they are on back order.
The steering seems to be ok but I do recall lengthening the throw between the servo horn and the linkage. Could that have done it?
As for the pipe, it rocks. I still have some fine tuning but you can see if you watch the video that it adds power for sure, I had to hold back because I was missing corners

RE: Anyone Own a RT-X 27?
Hmmm... how much did you lengthened it? That might be the reason. I was having the same problem with the servo horns and i decided alu horns was the way to solve it. After that the problem transfered to the servo gears and i had to change them like 3 times. Finally i had to re adjust the end points (with digital futaba) and the problem was gone.

I've finally got the stock Super Tigre running the way I want it to. A few of the things that I did was to only run the truck for 3 to 4 minutes at a time for the first half gallon, and never in the lower half of the tank. I added two shims under the head, sealed the engine, went to only running 20% nitro, installed a Nova cooling head, installed a fan type flywheel, and also installed an HPI air filter. I've been running the truck now for about 10 minutes at a time and the temps are staying in around 275* F for the high. on shut down, the temp reads about 250*F. My glow plugs are no longer failing also. I think the break in period for this engine is almost a gallon. I run the truck a little on the rich side on the first run, and it runs just right once its warmed up. I made the mistake of trying to tune the engine on the first run, and chased the needle settings. I've learned a lot about these engines in the process of owning my first RC truck, but I think I've finally got the stock motor running the way it is supposed to run. It runs consistantly once warmed up and I'm having fun with it now. Thanks for every ones help. Duratrax has also been great about the replacement parts.

Hey thanks for the heads up JayRec! Will keep an eye out for those fractures.
Still can't get over the bug body, that's KOOL!

RE: Anyone Own a RT-X 27?
Thanks Skhills.... I did what you said and fabbed up an HPI Hellfire tank (150cc) to the side of the truck and low and be hold..... I ran the truck hard and had a hard time reaching 260 degrees! Finally on the very bottom (1/4 or lower) of the tank the temp ran 275.... But, as soon as I stopped the truck and idled for a few seconds, really just a few seconds, the temps came down to 260 to 255 again. I am impressed! The truck ran better, stronger and so much more consistent than with the stock tank. It even did wheel stands a few times (5). That has never happened except on a rare occasion. This run today, albet only one tank before the sun went down, has been the best the truck has ever ran.
As far as the tires/wheels go .. i think mine are just shot... they are very wobly and make me uncomfortable at high speeds.... What do you think of the savage wheels and tires? I really like the LST xxl wheels and tires. any thoughts ...

i apreciate your input...but...PLEASE REPLACE that tank; or replace your engine in the very short run. I tried every thing under the sun to seal that tank (epoxy, goop, etc. even remelting the plastic. if thats a word. it all worked for about 2 tanks... problem is nitro methane eats right through anything u can put on it. Im only trying to help, not argue..do what works for you, but dont say i didnt tell you.

That's nuts, Steve... Glad your having success with the ST motor. Wish it was easier, but, seems like you did a lot of good with those mods. Unfortunately, I had a bad carb.... And chased heat issues until I finally bought a new motor. Then changing tank so far has been the biggest success battling the heat issues. Once Duratrax sends me a new one I will install the carb and use the ST motor as a back up.... BTW, what aluminum parts are you getting, curious here....

RE: Anyone Own a RT-X 27?
Just to add to the clutch and bell combo. I installed an Ofna 16T vented clutch bell with Mugen aluminum clutch and Mugen 1 mm springs. I want to go to a 17T bell, but, will have to mod the motor mount area to get proper gear mesh. So far with this set up I have had no issues and a lot better take off off the line.

I purchased both aluminum differential cases and both aluminum transmission cases. I already have aluminum bulkheads and A-arms. The only other aluminum parts I may get is the shock towers once they are on sale. I wish Iwould have bought aluminum skid plates when I had the chance. The Super Tigre is running very good now. I'm going to try a differant tank also, just to see what happens.

RE: Anyone Own a RT-X 27?
I just checked prices again and Tower has brought the prices back up on some of the parts. Both cases were only $10.00 each for the diffs, and $19.00 each for the tranys. Now I see $24.00 and $45.00. I must have hit it just right. Looks like the rear blue, and the front purple is still on the sale price though.

RE: Anyone Own a RT-X 27?
WOW! That's some extreme temperatures!!! Have you sealed your ST motor? Carb mounting area, pinch screws and the rear backing plate. Also, seal the tank pressure inlet and fuel outlet. And if you have not changed your fuel lines recently, they can wear out and have pinholes that are not visible to the naked eye. After all of the above, my ST never ran hotter than 300 degrees and the Axial as well. Atleast I never let it get higher. I always freaked and shut them down to cool.
If you try a new tank, the Hellfire tank will fit in the back as well. But, with the stock plastic bumper I am worried that it will be more vulnerable back there. I may move mine if I pick up an aluminum rear bumper and figure out how I can mount a body over it.

RE: Anyone Own a RT-X 27?
Idid seal the carb/motor as you described. I haven't done the tank yet. Ido have some new fuel line so Iwill try that next. The truck is only 3 or 4 months old with about a gallon of fuel through it. Iassumed the fuel lines would be ok still. Cheap enough to change though. How many total shims do you have now?
I am getting those temps while still running richer than Ineed to as It is not getting up to speed and shifting like it should. If Ilean it out more it runs awesome while still giving good smoke until it heats up.
