Raptor37

Even though this is an old thread is very interesting .

Raptor are very nice fun flight units . I used to run nitro , then I decided to get in to the gasser monsters .

I started modifying a raptor 30 size running a 37 OS engine , and now I used 89 octane and systetic oil , at 30:1 for better performance .

but I ended up installing a Rxcel ignition and a 1/4-32 plug for it .
the OS carb needs to be replace with the diaphragm type carb like walbro or zyma  and the play until is right .

and belive me  the little monster is alive and it has the performace of a 50 size .

the electronics are a most , and because of the torque it generates , you need a good gyro loke the futaba GY401
and a good radio gear such as the T14sgh.
