i need some help deciding wich engine i should get for my jammin fte. buggy. i am looking at the o.s 21 v-spec , and also the jammin .21 , Axe Rossi Mamba .21, or the Novarossi N21B 2001 BF .21 ?? wich one would be best? the track ill probably be running on is medium-tight with a strait. is there any good info about the jammin .21??? please let me know, i need one soon! thanks

I`m gonna buy the novarossi N21B 2001BF for my CEn Matrix RTR...I had it with the NX26...way too much trouble for what i paid for...the BF i heard is an awesome motor. hope i get a good one!...should be here next week sometime...will let ya know how it does....novarossi is top of the line . just try it and do the manufacturer`s break-in proceedure...u should be fine...they say u`ll be amazed with this engine...we`ll see...lol....good luck man

lol alright...wats the diffrence between the 2 of them at amain? one of them is 249 i think and the othr is 170? or soemthin...wats teh diffrence?

Out of the 3 you listed the OS V Spec! Has a whole lot more top end then the N21B 2001BF I do believe.

You obviously have a good budget to play with, [link=http://rc-mushroom.com/product_info.php?cPath=169&products_id=12378]so just get the best V-Spec available.[/link]

I have been hearing really good things about these Go-Tech engines. they make 3 port 5 port and 7 port. I hear people comparing them to novarossi and they are considerably less expensive. I know a-main carries them carolinasrc, and rccompound also carry them.

cool, thanksf ro the info guys...i think i might go for the o.s v-spec....it has the most votes from people...anyway...wat pipe would u recommend running? i have a jp-1

Well I went the AXE Rossi Mamba route, but I don't think its necessarily better than the others. Then again you can get it for $200 and will hang with most of the engines you mentioned.

The mamba is a great engine. Normal plug so you can save a few bucks on plugs. My mamba hit gallon 3 and still running strong. Rossi makes a turbo button if you want to go the turbo plug route.
