If you didn't have a way of measuring your top speed before, how can you be sure you really lost speed?

The top end scream was elusive to me for a long time - I run Losi Monster Trucks... Been running Losi/Mach .26/.28 engines in them for years. Finally decided to get something with some real punch - so out with the old and in with the new... Nova Legend 28-8RT in one LST and Picco P3 .28 in the other. The Nova is still stock with 41017 header and 9886 pipe, but the Picco is modified and uses a 41016 header and Dynamite 086HS pipe. The Picco truck is the one I run all the time - getting it broken in good. I'll just say that it would be worth your while to save some $$ to get one of these better engines later on down the road. The power and ease of tuning is so easy. Use a cold/medium plug and a good dose of nitro and they just rock. I'll have to make a video one of these days - These things scream.
