What is considered the most powerful engine/pipe combo in .21 off-road engines? I need a pullstart capable engine with a standard glow plug. If you have a combination you like let me know also, I some suggestions.

Would the RB TM728 pullstart fit on an Xray Buggy, or what about a Novarossi XRP .28 pullstart?

Are you stuck on .28-.32 size motors? Im willing to bet that a RB WS7II X3 .21 will walk all over their TM728. Bigger doesnt always mean badder. If you are going to spend $300+ on a motor why in gods name would you want it to be a pullstart?

You will be lucky if a pullstart lasts a quart of fuel. Spend the $80 for a decent box and make sure you get a motor that you can handle. There are so many motors out there that people just want to slap on something huge and its so fast they cant control the car.

the most powerful engine will never come fitted with a pullstart

get a starterbox & a decent Race .21 & you'll have all the power you need

dude u are asking a question then changing it.first of all u wanted to know what the most powerful engine is that is a hard question because there is so many fast reliable engines out it is not funny v-spec,p5,rb ws72,73,rb c5 ,rb s5,ops speedster,top 421b and the sirio kanai 2 ,3 just to name a few.but i garrantee u without a shadow of a doubt that NONE OF THESE ENGINES ARE A PULL START.and no matter how much power you have if you cannot get it to the grond it does not matter.also having a standard head limits your choices quite a bit.

have fun with youre searh but try not to limit yourself to a pullstart and a standard head if you are looking for the most powerful engine.

If you put a pullstart mill in your Xray I'll have to come kick your arse......for 300 you can get a P5 AND a nice starterbox....so much power it'll make you wanna slap yo mamma!!!!

The fastest motor i have seen so far is the JP racing b8t and it has the best feedback in my store as i sell JP RB Collari Novarossi & os jp is the best

You can get a new P5 for $270 on the internet if you look.

Hey guys I got myself a mp777 sp2 and RB WS7II X3 .21 as a moter. I was thinking that I should use this engen for races only and use a OS RG for just beating the car around. Is this a good idea or just stik with the RB WS7II X3 .21 all the time. The only reason I ask is I here the paformance goes down after about 6 gallon of fuel. Thanks.
