yeah... that is what I was thinking. It is very close to the perfect length, but needs just a bit more

To see if your con rod is broken, just take the glow plug out and turn the engine over with the flywheel.
The piston won't go up and down if the rod is broken.

Just take it apart and check the Piston.

There's also the HPI Engine Exchange Program. http://www.hpiracing.com/engineexchange/

$65 for a new .18 is hard to beat. The rules say you can exchange small block for small block. You might want to find out when the .18SS will be available. The .18SS, stock on the MT2 18SS was dynoed by Extreme RC Magazine at .63 hp @ 29,500 RPM and 24.96 oz-in @ 22,250 RPM. The stock Storm engine on the same dyno was .56 HP @ 25,700 RPM and 21.83 oz-in @ 25,500 RPM. HPI states it's the same engine with different porting. The SS has more torque down low and more HP up high.

I wouldn't pay $150 for a 4.6, although it is a good engine, I'd rather have a LRP for almost the same price.



My thoughts on the starter cord question is get a starter box. For $75 I got a dual 750 motor dual belt drive and use a car battery.

It's more powerful than my $100 Ofna dual 750 motor Truggy starter box which uses a single belt.

Well I just bought an OS 18 CVR for my firestorm. I got a desent deal (I think) on ebay. It was 72.00 and only has 6 tanks of fuel run thru it. From everything I have found it is a drop in engine. once I get it in I'll be sure to let you know who it runs!! I'm n ot sure what I going to do yet about the stock engine I may keep it as a spare or maybe I'll post it in the classified section for sale.
Has any body else done this swap yet? let us know how it went if you have.

Are there cvds that will work with this truck?

Check out my thread, Firestorm O.S. Engine Swap, for info on installing an O.S. 18CV-RX 11J .

I know. I'm a mechanic lol. I just hdn't taken the time to do it when I posted earlier. But I did pull the plug and check and actually the piston still moves up and down. I pulled the top end off and well, the piston is cracked and the headgasket is popped. So good news is the con rod is fine. Bad news, the piston isn't. Oh well. I bought myself a Caster buggy and introduced myself to the yummy goodness of the ZX-1R.

Thanks for the link. I think I will bookmark it for reference when I install my engine. I also got the high torque sterring servo and it was the best thing I bought for the firestorm so far, you won't regret it. I did tighen my servo saver all the way and it keeps coming loose I'm going to have to locktight it next time I have the front end apart.
Thanks

experimental_pilot

Oh, lol!
That sucks about your engine, but congrats on the ZX-1. They look real nice.

I love it. But never fear the 'Storm will be back. It won't really be a truck anymore, but it'll be a fun rebuild. I've got too much invested in it to just let it die like that.

will0983

where did you get the new servo from. I am looking for a good steering servo for my firestorm. thanks

get a hitech 645, you can find them on ebay or tower has them for under $30.00 (I think) you can probably save a few buck if you get one from ebay. Your LHS should carry them in stock and you wouldn't have to wiat for shipping

Just a quick question or comparison I would like to know... How far have you turned your HSN and LSN from neutral when leaning out your mixtures? I'm just wondering if anyone has gone past 1/8 and 1/4 turns. Sometimes it seems that I can almost do a FULL circle clockwise on my HSN and 1/2 circle on my LSN...

3pointX

I kept mine pretty close to that magic 3/4 turn for the high speed. I never messed with my low speed settings.

kordasn

I have had my LSN up to 1 full turn lean, it's still fine, though I run it at flush, I really don't know how far it should be pushed I am going to buy a temperature guage tomorrow to make sure I can keep it below 250^F. I'm not too crazy about speed, I'm going to go get a lower tooth clutch bell (17), and change the springs to be stiffer on the shoes. I'm 99% sure it'll wheelie off the line and I'm sure I'll throw out the back end on the dirt, even if it is a bit richer than maximum performance. I end up driving it in the grass a lot at home, I am considering constructing a track at my cottage made of dirt, it doesn't wheelie in the grass too much. We'll see.


Also, for the starter I use a rotostart now, works like a CHARM compared to pulling on that thing, even though the stock 'storm body doesn't really fit the roto quite properly. ~$65 @ hobbyhobby for the starter, $30 for charger for battery and lastly $30 for the backplate, ballpark of course. My dad bought a MT2, pretty nice car it came with a rotostart .


I had a couple questions also, 2speed? And also can you get a better brake? I have straightened out the connecting rod and lubricated the linkages, but it doesn't lock the wheels. I WANT IT TO LOCK THE WHEELS! Anyway, should I / can you get a stronger servo for that? On page 20 there was a discussion about it. It would actually be best if you could let me know something from this list:
http://www.hobbyhobby.com/store/inde...ath=24_216_278

I'd like to not spend too much money, but maybe like... Any purchase will show great progress. I have no idea, anyone got any?

supersound99ss

i can't get past an 1/8 turn on the HSN without the temps staying in the 260s+.....i don't really beat on mine much but for some reason its always running hot but has smoke 6ft behind it

I use a rotostart on my Savage. Like it more than I thought I would. Use a 3000ma battery and rarely charge it.

The best thing about the Storm is turning the wheel and locking the brakes at the same time. Once it's sliding sideways hit the gas. That is what two wheel drive is all about. The stock arm on the Storm brake is too short and it comes off at an angle instead of 90 degrees. I attached an aluminum plate to my brake arm that extends out 2" and it's triangle shaped to allow the rod hole to be 90 degrees to the brake shaft. I still have the stock servo and the only time I can't lock up my brakes is when my battery is almost dead.

tokenring

right now I have my HSN at 3/4 turn clockwise and my LSN 1/2 turn clockwise. I think the LSN is horizontal at flush right????

kordasn

Hey P Bear, what did you fabricate the aluminum plate from? I was thinking of using a popsicle stick, I can't really think of anything to use. Did you remove the stock one and put it right into the socket for the brake lever, or did you attach it, if so how?

Thanks again

kordasn

On both my G3.0 on the MT2 and on the FS it's vertical when flush, it may be different though, I do not know.

P Bear

I used .105" (2.5mm) sheet alum. from work. Little less than 1/8" thick. Attached it to the old arm. I wanted it the same level with the old arm so I epoxied it to the edge. Worked for about 2 hours run time before it came off. Now I am going to re-attach it to the same spot but use another piece of alum. on top and use 4 small bolts and nuts, 2 on lever and 2 on 2" plate to bolt it on plus use epoxy again. Won't fall off this time. They sell sheet alum. at my local hardware store. Anything between 1/16" and 1/8" alum. would be good. With a popsicle stick you would have a hard time getting 90 degrees to the brake shaft. Doesn't have to be 90, just gives you more leverage.

tokenring

I think you're right... the only reason why I wasn't sure is because firstly it is hard to tell by the naked eye (when flush) and secondly when I took it to my local hobby store, they quickly moved it (the leaning way - clockwise) without me looking. It was at 1 o'clock after he they turned it, and I thought he turned it about 1/4 turn. So if I moved it back what they moved it forward, it would be at horizontal. I guess they only moved it a bit... from 12 o'clock to 1 o'clock and not 9 o'clock to 1 o'clock No wonder my engine was flooding previously... Arrrrr!!! Anyway, it's good now!! Thanks for the reply Kordson!!!!

Can anyone say wheelies????

kordasn

I can't get mine to do wheelies, in grass or pavement or dirt, unless I hit a bump. I have had the HSN turned in fairly far (but it makes it heat up too much), so I have turned it to around 220~240, but I've not seen any wheelies. I suppose I could try the LSN, but I don't know if that would actually help without wrecking the engine. Any help from anyone?

I read before that if you tighten up the slipper it will wheelie? But it will cause wear on something? What is that thing which will wear?
