This is the Novarossi Beat BT5 .21 off-road nitro engine. Based off the popular Novarossi 5 port long stroke configuration, it’s a great value for buggy and truck racing. The performance of the BT5 exceeds its price tag. The Beat BT5 provides linear power output and great fuel consumption.
Being a Nova I already knew this engine was going to be great but I am still in shock. After Break in, I went straight to the track and ran in on the break in tune for another 4 tanks. After leaning it maybe 2 hours on each needle (still pretty rich) this thing ran AMAZING!. Put about a gallon on it in one day of practice. I probably did 4 or 5 45 min mains worth of practice and it took it like a champ! Def a good cost alternative to the Nova P5. Cant wait to race it for real.
