i bought a few months ago a used but just after break in MAGNESIUM "light colored head" sirio ( Schepis Model .21 ) from answer-rc-usa.... its been sitting on my shelf for a few months ( one of thos buys that i thought would sit there, no rush to use ) anyways last night i got bored and bolted it onto my light weight carbon fiber mugen buggy , it started first kick with the plug it came with but kept flaming out . put a new turbo plug in it and and it ran perfect .... OMG the power! that this thing has hahah its a weapon .. i reckon it has more pull and power than my DRAKE .21 PLAT ed .... cant wait to really stretch its legs on a big open place this weekend . all smiles

If i'm not mistaken it is based on the Sirio CL7B. Should make good power :D

yeah thats the one bro :) .

Nice engine, indeed very powerfull :cool:

This is in the wrong part of the forums. It belongs with the engines part of the nitro off road.

cant wait for a good test with it .. i dont race so im not running any carb insert and im running a novarossi pipe ... dont know the number of it off hand .. the buggy is super light as well so should be a weapon.

.

its a old thread it has not been moved yet ... chill-bro :)

It will probably get moved when one of the mods notices it.

Btw: get a 2013 offroad pipe for it and you will be very happy :D

cheers bro .. question tho .. that number pipe is made by a few engine companies yeah ? ...is there one thats a lil cheaper than the rest? .

Your best bet is RC-Mushroom: get the Sirio 2013 offroad version (apparently the onroad and offroad 2013 differ slightly)

You want this one:

http://www.rc-mushroom.com/product_i...ducts_id=20033

Partnumber Sirio S21-200120

It's the new version with the thicker walls and braced stinger. Don't think you can get it much cheaper.

cheers bro .. thanks for ya help :) .. gunna just stick it out with the pipe iv got for now .. but in the future might grab that pipe .gunna take it out on the weekend if its not raining to get it all tuned in (dam winter %$#@ )

could not give it a good run last night because i had to lock-tite the engine mount bolts that go through the carbon-fiber chassis .. unlike the alloy chassis the bolts come loose with-in 5mins .should be all good to go now tho :) .
