Default Engine choice for Truggy

Hey all

I am purchasing a MBX5-T Prospec and have sorted most of the combo except the engine. So far I have decided on the truggy, Hitech 7955's, Use my existing 3PK and have a new receiver and 2300mah lipo.

I am going to go a RB engine i just need to decide which one
please don't suggest other brands, i am really just looking for info on these engines. I have a vspec, don't like nova's and want to try a RB out of the rest.

my choices are;
RB CONCEPT C6BBT II L2G (.21) and
RB CONCEPT RT L2G (.28)

I am looking for power and good fuel consumption with atleast 7min run times. I would prefer 8min+...

The RT is pretty much just a redesigned 928 i hear.

The track i race on is 340m long, fairly technical, bumpy, and short run ups to large jumps...

Also what RB pipe would you recommend for what engine you recommend.

also as a general question, do they allow the .28's to race in sanctioned races or do they seperate them from the .21's? generally.

whats your thoughts?

thankyou!

The 24 EX Tech is the sickest truggy engine I've ever ran! =)

no worries. though how do you know a relatively new engine will out last a RB? have you run 12+ gallons through one?

For the sake of the drive line I would go with the a .21. I have a P5XS in my MBX5T and love it, With that I am getting 8:30 runtime.

im a bit surprised you dont like Nova rossis but want to try a RB, anyhow it seems most run 21 in their truggies they give good run time power and keep the truggies living longer with less stress on the drivetrain etc, why have you limited yourself to just 2 engines 1 .21 and 1 .28 there are lots of .21 from RB also WS7III, S7L2G, S5L2G and the S5, to be honest the S7L2G is also a pretty good engine and has won high level races also it just comes down to the driver normally anyway, it depends on the budget you have i suppose and out of the 2 then go for the .21

A smaller engine is always going to get better mileage than a larger one, so from that line of thinking I'd suggest the .21. That's the size I use and I get way better mileage than my buddies that run 28's.

Whether it be sanctioned races or not, .21 and .28 motors are both allowed in the truggy class. Only the buggies have a .21 limit.

go witht he .21 over the .28...the .28 usually just weigh more and you dont gain that much more performance wise and they drink more fuel..the .21 will get you the lower end punch you need for those short run ups on jumps and wont use hardly as much fuel..

28's tend to have more low end punch as they have more torque than 21's which are more of an RPM motor.

Hey Joe,

What makes you think the Extech will last longer than the RB??? And is the .24 ready for shipping??? Can you really just run the EB version as it comes without additional break in???

I’m also in the market for a truggy motor (CEN TR)

I really like the OS .28 and that seems to be the motor most of the guys are running @ my track (revelations)

My buddy Colin has me thinking Extech.... And claims it pushes his TR around the track no problem (no video though, just results!!! LOL JK)

The guy I go to the track with runs RB's and has 11 gallons with nothing done to it..... And wants me to run a RB.

pracy... Sorry to jack ur thread.... I would run the .28 in the truggy. You will overwork the .21 in a truggy IMO. I ran a RB S7.21 in a MBX5 and I think it needs more to push a truggy around.... Unless you have it modded...
"There’s no replacement for displacement"

What do the fast guys @ you’re track run??? That’s what I would..." got to keep up with the joneses"

The GO 25, I run a PTM GO 25, get ten+ run time and all the bottom end you could want.
