That engine is not possible to buy, even from Huston, CRE or anyone. Only one person as i know have theese engines and he have helped me meka one.

Os-vspec engine. Crono 2032 pipe. The 2032 pipe on this combo makes the engine hit the pipe a bit hard but on this track it is not a huge problem. Nitrothane 30% fuel, Losi Car ( somehow that car use less fuel than many others...) OS p6 glowplug as a 3 or 4 is just to warm to get the best fuell milage.


My +4 is a BTT team engine lightly tuned by my self. I am not a skilled tuner like MOnty, Murnan or CRE, but it is better than stock. Crono 2032 pipe. Meccamo 25% fuel. C6tgc glowplug. Standard compression. I use a IDRC restrictor as they help a bit with fuelconsumption too. Problem is that the OS speeds are fatser so i need more topend on that LONG staright :-)

Clutch setup is important also, but i do not remember what clutch i used.

Moast important is how you use your throttlefinger. If you press to hard you get wheelspin, and less runtime. The harder you have your clutch engament, the more fuel you will use. A friend of mine ( best driver here ) switched from 0.95mm spring on his Kysoho to 1.0mm springs and lost 30 seconds runtime..
