I do not beleive that is a true 7 port........ it is just a 5 port being advertised as a 7 port.................. Stilll a nice engine but for that money there are more potent engines for truggy...

Yeah, that engine is way overpriced*. It is meant to be quite nice though. It's a Picco, basically a P7 Evo 4 afaik. Which means it's very close to a Jammin JPX .21, with maybe some minor changes to the carb for more run-time etc..(i.e. if anything just a tad smoother than the Jammin..)

* It's available for much cheaper here in Germany - €200 on sale now and again, which is much more fair..

It's a $600 engine priced $60-$80 below cost. Just blowing the last ones out. It's not a $200 engine priced at $230.

Hope that helps.

It is a good engine based off the older P7/Jammin .21 5 =2 port Picco engines.

Older design, not the greatest mileage but a good running fast engine.

I see there's a Spec 3 now.. Which seems odd, to come out with a newer Picco-based engine when the main high-end LRP-branded engines are OS based.. Looks like they have a MES exhaust now (5+3), tungsten on the crank, etc..

Weird though.. AFAIK they now have three separate .21's under the LRP name, each from totally different factories(OS, Picco, SH/Taiwan..)

But yeah, good-weird though.. The more nitro engines out there the better..
