Arrow Racing GTR .21 Engine Thread

its similar but def not the same. little things makes a big difference. when taking it apart, the sleeve is similar to the VZB but the crank looks different. it turns far more RPMs, i never had to give it over half throttle and it was still pulling all the engines, even SPEEDs. if you like the VZB or Speeds then you will love this engine.
i never like the VZB, i had a few and they all felt weak, this one reminds me of the JP modified one, but i still think it has a little more than it, it might just be putting the power to the ground, but it gets going in a hurry.

i knew someone was going to say something, but yes, i never liked the VZB, SPEED or XZ Speed, i didnt like their power at all. only 2 OS ive liked that i tried was a Murnan Modified one and the JP Modified one ... everyone likes something different, all of them were great, personally i didnt like them.

I have 2 1/2 gallons on my GTR and it is a good motor, and have had the old style speed, and wouldn't even compare the 2. Don't get me wrong, its a good motor for the money, there's alot of new motors out now, and I've tried a few, and I'll leave it at that.
My motor set up was posted a few pages back, mine is set up for smooth linear power band, mad power doesn't mean much if you can't plant it. I also get better than average run times, theres a few here that were there when I ran a 12 minute main on the big track at Fear Farm on one tank.
I did pull the break in shim out after 1 gallon and am still running a P3 plug.
I will say the head does sit alittle lower than others and is lighter.
Don't take this the wrong way, I'm not knoking the motor, I've had good success with it,just giving an my opinion

Got one tank thru it, had to stop mid way of cleaning due to dinner
. Idled the first tank, was a pain to start, totally forgot stock is 8mm res. and i put 6.5 so it comes stock rich and i made it even richer doing that lol. After some needle tweaking idled great didnt die or give me any issues. Really hope i get enough fuel thru it before friday

The Bullitt p/s is the same as the XZ-B. How the Bullitt B-218 got brought up in the Arrow GTR thread is beyond me though.

I'm using the Losi RE10 with the 8mm restrictor. I get 8.5 to 9min rt. Will be gettimg a 7 this week. Combo has plenty of bottom and all I had to do was put a 14t bell on it to get more topend and still have bottom to spare.

if anyone is interested in an arrow, 1/2 gallon on it, couldnt get it to run right, i believe it needs orings on the needles, they were loose but i put my nova back in and fell back in love with it and done with testing other engines, im sticking with nova.. pm me if wanted
