Status: offline 		Looks good. What is your gearing on that beast. I hope that your taking full advantage of all that power. The one thing that can be improved is the rear tires. I tried those and liked the fact that they run like a belted tire but traction is terrible. Are they the m or pro compound? My street truck is still sitting all busted up from running rubber tires. I have tried just about every brand and make of street tire. Duct taping the tire will help out emensley if you have steeper gearing. Helping with tire wear and the infamous torque steer tire balooning cartwheel of destruction. Thats what killed mine.

Mine is entirely apart now, new chassis is here..just need to cut the slot bigger in it and can start building.

Status: offline 		not sure on the compound but it seems to work very well with the large buggy wing, never ever spins out but the tires balloon like mad. but they come back awfully warm after even a short run. its just running the stock gearing but i am looking to get a smaller spur because i dont have the room for a bigger clutch bell. and another issue i have found is the flywheel is too small for the starter box, so i will be switching that soon. maybe now?... be right back :P

Status: offline 		They must be the pro compound then. For the gearing you need to swithch it out to the 1.0m 32 pitch a 38/18 or a 36/20 would do that motor some justice. For the fly wheel it might be a pain since you have to diassemble the entire truck but just make the bottom hole bigger to get the bump box in there. I highly recomend swithching to a good aluminum 3 shoe the stock clutch is terrible especialy if you added a bigger motor. I have bought 2 storms used and both of the where pretty much new. The tires didn't even show any wear and on both trucks the stock clutch spring was broke.

Status: offline 		The stock clutch spring is the weakest point on the truck.  Many people break them in the first litre of fuel.  Read back, someone describes the symptoms about every five pages (and sometime twice on the same page?!).  I hear you on the X-box.  I hear the new Duke is disappointing.

Status: offline 		I may be the only person who ran two gallons on the stock spring without breaking it.  I wish they upgraded the clutch in the newest revision of the truck.  The servo saver needs an upgrade as well.  They put a different version in the blitz that is much easier to service and I've noticed it doesn't come loose.

I am tempted to get my storm out but am hesitating because the engine needs to be broken in and I want to sell it and think it would be worth more without the break-in.   I did some engine flipping with my buggy and truggy during the winter and ended up with another OS .21vg in it and pinched the sleeve and put in a new conrod and wristpin just to be thorough

Status: offline 		go on run the storm! you know you want to   after tuning i have realised i need taller gearing on the car because its front wheels just dont touch the ground. and its top speed is immense but it does run out of revs before it runs out of power so does need a smaller CB. but the power i get from this used truggy engine is still too much for this little car, chucks it around dohnuts on command and will perform a rolling burnout when the tires are cold. all i need is some front brakes and i can make it look like a proper dragster. and the only other change is it needs much thicker shock oil... i remember putting in some un-labeled shock oil about a year ago and it was far too thin. but because i mothballed it i never knew. 

And the new Duke Nukem is truly dreadful but to be fair the original was just as bad... its just more of a joke than a proper game. 
portal 2 is where its at

Status: offline 		I just started portal II last week and am enjoying it.  Lego batman and starwars, too.
 
I decided to wait a bit on driving my storm  since it can get sold at any time.  I also have to consider that I havn't driven my savage or Losi 8t2 this year yet (and the losi has a litre through it since last may).  I also have a D8 that is pretty sweet so the storm gets a lower priority than the other nitros (that are already not getting driven much).  My four year old savage has maybe five gallons on it. Pretty sad, actually.  The only nitro I've driven this year is the D8.

Has anyone considered going to high voltage servos on their storm?  I'm running 2s lips and appropriate servos on the other RCs and they are fantastic.

I bought a DX3R pro the other day and the framerate can be adjusted to 5.5ms.  I didn't think there was a big difference between the 3S and that radio before getting it but the pro is much faster and makes high speed servos sing.
 
 
Have you considered playing with the weight bias as well?  I've been tweaking my Estorm a lot this year and am getting a lot more out of it now.  I played with front to back weight balance and found something that is just the right balance of rear traction and steering.

Status: offline 		I am quite content with the jr digital servo's. The high voltage ones are out of the budget. Also did you have range issues with the 3S. I am thinking about making the switch to the R as well but not interested in staying with spektrum if it is not worth it. The S is terrible in my book. If it wasnt for the adjustability stock am is far better than mine.

I have made another modification to the 3.3 dirt truck motor. I installed the backup 8mm carb for the hyper on the 3.3 and it is pretty much a retarded fast basher. Today that lil monster saw a little of everything pavement, dirt, sand, plus hit a couple jumps. Still in no rush to fix the other one since the other guys have yet to even start their trucks. Now I am looking to find some time and the appropriate space for a vid of the 3.3 beast.

Status: offline 		The 3s never had the best range and something happened and it dropped a lot suddenly.  I will send it in for repair.  The range  on the 3r pro is good but I've had some stuttering at the limit of my practical vision and can't tell you how far that is but will play with range a bit more.    I'm sticking with spektrum for a while since I have eleven receivers and they aren't cheap.

Status: offline 		Here is the video of the dirt truck that I finaly got around to taking. Sorry it ended up being on pavement and not some dirt. It was getting dark and this is about the only time that I can get around to drive it now. It has a little bit of a high idle but it is just like the hyper she is hard to get past 200 degrees.http://www.youtube.com/watch?v=Z-1sWZ3EpaU

on my prepped road its even more violent.. had to adjust wheelie bar to only let it pick the tires up about 1" or it would stay on the bar entire way down the street.

Status: offline 		I am back to single speed. After busting 2 HPI (locked) diff's, i got rid of the HPI rear all together and am using the rear out of a Duratrax truck (3.25 gear) that i narrowed about 1". With this rear im able to choose from a much wider range of gearing now, and currently have it setup with a 7.67 final (20 pinion, 47 spur) as this let it peak alot sooner, and was doing better for 132ft running.

Motor is doing good since the truck has been apart. I started fighting bad issue with it wanting to go left hard right off launch, and it ended up being the chassis bent real bad, so i got another and have just been slowly putting it back together, and trying to brace it as much as i can to try keeping it from happening again. And im also changing it up, as the new chassis has absolutely no suspension.

I put together another Hyper with one of the 8port sleeves that was real tight, using stock crank and have it in my RS4 and just been beating on it. Soon as the gearing comes off backorder for it, im gonna put the good motor in and see how fast i can get it to go.

Status: offline 		Looking good Will. The pipe is hurting the performance a little though. These little demons need a good pipe to wake up instead of that rtr ofna muffler. I also seen that in the rs4 thread your kind of on the 3.3 thing in there. IMO between the hyper you have and the 3.3 done up the best I can with the 8mm carb and on road pipe with a little better timings. The 3.3 is absolutely wicked but it is a real smooth strong pull that keeps on going from the bottom to top as seen in the video. On the other hand the Hyper is a real hard hitting beast that just seems to break parts in the driveline.

I raised some of the ports on the sleeve in my motor and maxed the timings. With the truck as low as possible it just takes flight after 65. I also keep throwing dogbones on take off and can't figure out why. Nothing is broke and there is fuel line that keeps the dog bones tight so side play is gone.

I am also in the works of doing some tests with a jato again. The top speed of my modded 3.3 compared to the Hyper. Right now with stock gearing and the modded 3.3 without the 1/8 scale parts it is doing 70 with plenty of head room. The gearing is going to be changed and see what comes of the 2. The 3.3 is going to be first because I am pretty sure the Hyper is going to destroy the trans. Just waithing to get the jato back.

Tim, i agree the pipe isnt the best, but after i opened the stinger up a bit, it has produced speeds quite close to my MAC's marine pipe. I did pick up some novarossi pipe for the RS4, just havent stuck it on yet as i need a better header setup, just havent found one yet that looks like it will keep the pipe in the same position (putting the pipe to the right side is out of the question... have to mount it too high to clear the tire)

Status: offline 		It has been a long while since I've last logged in, but i got out the storm for the first time yesterday after it sat for a whole year and it started on first pull I was amazed but my victory was short lived within the first half hour I smashed it into a parking block and annihilated the whole front end of the truck. I need new front complete bulkhead kit, servo saver set, upper deck, and shock tower. I am debating on whether getting all new aluminum or stock, aluminum $165 total from integy or stock crash kit from ebay $65 with shipping and that includes an aluminum brace for the upper deck. Sorry no pics but for those who want details, I lined up a jump punched it hit about 70% full speed stock motor and diff, then the rear end hit gravel and the truck darted to the left and into the curb...any suggestions

Status: offline 		I would get as much rpm and stock stuff as you can. The aluminum looks nice but will egg out and give you a bunch of unwanted slop in the front end. I am currently in the market to get everything it takes to do 2 trucks with all new parts. The aluminum that is on my street truck is so loose it makes the truck hard to drive at speeds. Plus it's half the price
