Arrow Racing is made by GO Engines in Taiwan at their Taichung factory.
Bullit Engines is made by OS Engines in Japan at their Nara plant. XZ = Long stroke VZ = Short stroke Arrow is based on the short stroke VZ. The engine is a clone of the VZ-B V-Spec. It doesn't share anything with the VZ-B Speed, except for the fact it was designed with that style bottom end lubrication (the oiling hole was moved from the crank pin onto the rod to increase lifespan). Bullit engines are based on the long stroke XZ engines. The 216 is essentially a XZ-B V-Spec while the 218 is essentially a XZ-B Speed. Everything fits in a VZ-B. The only thing that fits on a XZ-B is con rod, wrist pin clips, front and rear bearings, carb retainer, backplate screws, and the entire carb (just switch whole thing, I wouldn't mess with mixing Arrow carb parts with OS ones). That's it. Crankcase, backplate, crank, piston, sleeve, head button, head gaskets, cooling head, and head bolts are all different. what a great post! thank you for taking the time and explaining everything. i really appreciate it. i'll print this post and stick it in my binder. now i'll feel alot more confident answering questions when im at the track! :) |
Hi,
So the VZ-B Speed crank will fit the Arrow GTR........ |
Yes. I have fit one into my Arrow.
And works like magic. However, it lacks in the long straight. Arrow is better. Extremely fast down the long straight. |
Broke the gallon mark and the Arrow came alive today. Plenty of low and and nice top end. Initially I was worried it would be a little weak on top but she was a bit faster after loosening up.
Running on a fast high bite indoor track, it will do 10 minutes. I think this is the smoothest motor I've ran. Very pleased thus far:) Oh using an re11 pipe and Byron's 30/9. |

I just want to say one thing... the quality is up there on Arrow. I know saying GO freaks a lot of people out, since they lump it in with the no longer GO Tech engines. The truth is GO makes dozens of engines under different names. The JS stuff was great when I ran it. The new GO stuff is good too.

Ya,mine loosen up really well.run with Orion 2058 pipe,runtime 10 min,temp at 115 degree,byron 30/11 on a big 30-35 sec track.gearing 11.97.

I didn't know who manufacture arrow engine.
since but the others seems to follow arrows trend over the carb selection. the arrow carb have good consistency. I ran over 5 months and no hiccup. try the speed crank, didn't like it. since gone back what it is. I could forsake a little low end, compensated by smoothness. but the high end, is a monster. I like the arrow simply becos it is a simple 3 ports engine with blazing long straight speed. |
sorry. I use ascendancy racing clutch with this engine.
it seems better than 3 pcs clutch. |
Hi,
Whats a good pipe to run with the Arrow? |
the Losi Re11 seems to be working pretty good for me. great low end and blistering high end. runtimes are about 8-10 1/2 min. depending on tune, setup and track conditions.

Well I started break in today. I had to heat it to almost 300 degrees to get it to tun over but my carb got so hot I was vaporizing the fuel :rolleyes:
Got the heat more concentrated on the sleeve and managed to fire it up at about 260 degrees. Ran 1 tank on the ground in slow figure 8's at same steady low RPM's just to get some fuel through it and seat the bearings. ran through the whole tank with no hiccups. Let it cool down and re-filled for tank 2 and got about halfway through it when my throttle servo died..I must have heated that to 300 degrees also :D installing new servo now and will continue break in tuesday. Hoping to get about 10 tanks through it by Saturday and then race it Saturday night. I went with the Nova 9901 pipe to start with |
