Default OS .28xz

I finally made my decision to use the OS .28xz with the Redcat Monsoon.I still don't know how long it will last on a tank.Any other engines to consider before I get a OS .28xz?

Are u racing or bashing? I mainly bash and get aprox 9 minutes of heavy duty bashing or racing with 150ml tank. For a 28 it is good on fuel but still uses more than a good 21. If the monsoon is heavy the os28 will suit it (if the transmission can handle it!)
The os28 is one of the best 28s out there, enjoy.

i havent read of anyone fitting a pullstart. The xz is specifically designed to be bump start 4 racing. If yor guna race i wouldnt want a pullstart, a bump box way easier. The os doesnt have crazy tight pinch so a bump box copes very easily. My os28 has had many many gals thru it, very easy to start, tune, heaps power, i hav only replaced the bearings recently.

that is a great engine ,get a starter box you will like it alot + you dont want pull start an a fine engine like a XZ, os engines do have alot of pinch and are verry easy to tune and hold a tune threw a wide range of conditions ,I have a tuneing screwdriver on me at all times and have to tune a pinch most the time with my piccos and my mach's but my os starts and runs like a beast cold hot humid or not the os is a monster with minute tuneing changes if any once you get it right .

Since it's powerful and it might destroy the transmission I might choose a smaller engine.I read someones post somewhere about a RB engine being the best engine.How's the RB TM523 .23?AHH!It's so hard to make up my mind.

If you gonna get an RB, get anyone excepting the 523. I've had nothing but issues with mine, but all the other RB's we use are perfect, awesome engines.

if you want a electric or pull start , the .28xz might be to much engine for you at this point in time , the xz is a race engine and is ment to be bump started on a box ,a electric or pull start on a xz is like starting a ferrari by pushinhg it and poping the clutch .

I was just wondering if I could spend less money. Now I'm choosing what engine to get that's between .21 and .28. What's the difference between the Trinity ExTech TT2 .24 and the EB tuned Trinity ExTech TT2 .24 besides one of them being tuned?Is one of them more expensive just because it's tuned and broken in?

I don't think I want a OS 28xz anymore.I want good mileage and still have a lot of power and speed.

That OS 28 is a pure all out beast. I havent quiet seen one run stock but seen a few modded ones run and its way too much for any truggy.. especially on the track. Stock, i hear its still plenty for the track. I run an RB 928TM and its not good on gas and is very hard to controll on a track, but i just bash anyway....[8D]

If I get a .21 engine hopefully it can move the Monsoon really well. On the review it said it was 8.37 pounds.

Since yor moonsoon isnt 2 heavy and yor gunna race get a 21 then, but if yor gunna bash get a 28. Check colts vids on utube re his modded vspec etc,they look very fast and probably worth the extra $.

On the review it said that it went 32 miles per hour.It had a 28 SH engine.32 miles per hour is not really fast compared to other truggies.

The os28 is nothing like the sh28. The os would chew and spit out the sh.

I've heard quite a few people say their OS 28's didn't last long til they needed a rebuild or new bearings..(seems a familiar thing with OS's...) Anybody here with the 28 care to comment??

I think I've decided to keep my OS instead of selling it(still NIB..), based on all the positive stuff I've heard about it. But in general I'm not into having to rebuild engines, replace bearings, etc.. I generally prefer to stay with cheaper SH-based engines, and just junk'em after 6-7 gallons if/when they c.rap out..(none of my Machs or LPR has though yet...)
