19-26
 
I got one of those by accident when I meant to get the stock one for the LST. The 19-26, I'm told, means switching to metal spur gears since they're the only ones offered that fit with this pinion gear. The LST and LST2 with the threaded bells offer 18-25(stock), 18-24, and 18-22, all from Losi. I don't know if anyone makes a spur gear to go with a 16t pinion, if a 16t is available. Have you seen a 16 tooth thread on type? I just saw the 16t on the RC Monster link, answered my own question.

tangerines are good for you, and their good for the LST

ya but im tryin to do away with the 2 speed bell that low speed gear on the bell thats not used for anything would make a world of difference id it wasnt there its gotta weigh a OZ. and lose that and the rotating mass === more power better mileage

brentmorl 02-23-2009 06:58 PM

i meant a 24 or 25 or26 tooth

Clutch bell
 
Is your clutch bell not the threaded type? If so, could you just take it off? Mines the LST version, maybe they were different.

The LST's are threaded...the LST2's are permanent.

rctech needs chat rooms....lol

?
 
Guess I didn't understand what you were wanting. The link to RC Monster on pg 1 shows threaded pinions up to 29 teeth. If you bought the LOSB3340 threaded bell from the LST and put only the high speed gear on would it be any better than what you have?

i guess ive never really looked at the treaded style bells id perfer a one peice if i could ever find one:flaming:

BrettL 02-23-2009 10:19 PM

Turn it?
 
If you can find one with the right high gear count, you could have a machinist turn it on a lathe and get rid of every bit of weight possible, namely the low gear. ?Just throwing them out there.

I think for the money a lrp spec 3 is the best buy. I did experience a bad front bearing at less than a gallon but I just replaced it with a $15 TKO ceramic bearing and everything's good to go. The engine makes a ton of power and revs a lot higher than I expected it to.

Here's what my spec 3 runs like in a stock geared lst/raminator:

I just replaced my stock one piece clutch bell with one of the threaded lst bells along with a rc monster threaded pinion and the stock plastic spur. I really like this setup with the dude's one speed hub.

Using the threaded bell really opens the door to several more gearing options. Along with using a different spur makes for a ton of gearing variations.

bell
 
I really like the threaded bell. Easy and cheap to swap gears.

i vote for the losi/dynamite mach 427... its identical to the lrp spec 3 .28... the crank is identical.... but the 427 is a MUCH better powerplant in my opinion... lrp's are too hard to find parts for these days...

lst engine
 
dynamite .28 platinum is the same mach 427 but has more bottem end both excelent engines but if your looking for even more power get the force .32 or engine that comes out of the tnx 5.2 think they are the same cheap and more than enough power also put the foward only coversion makes everything spin up quicker
