Top speed 4-Tec project... - Page 3

BoostCrzy · 03-15-2009, 01:33 AM

motor temps are in the 130-140 range after 3-4 back to back pulls...esc temps are much cooler...i think the design of this setup is very efficient for its size....the motor itself isnt an actual 540 sized can...its more like a 380 with cooling fins built into the exterior that give it the appearance of a larger unit.....I am hoping to have a "Real" 540 motor with a higher KV rating very soon to test with....im steering towards the 5700kv or 7700kv mamba...the extra rpms from either unit will translate to sizable gains in speed.....

Things is moving now. Gets some tires on it so we both can go 1xx this weekend.

Your almost there! great job. I was thinking of trying to push my nitro 4tech as fast as it could go, but I dont have any room for that. I run out of lane the way it is. Congrats to getting to where you are now. I'm very impressed.

Hey, as long as the stabilizers work!

How long is the road you run on?

CRISPYSQRL · 03-17-2009, 09:46 PM

I would say 3-4 miles

BoostCrzy · 03-18-2009, 09:22 AM

BoostCrzy · 03-18-2009, 07:43 PM

testing with BSR's and 5700kv mamba motor today netted a new best!... 99.4mph!!....so close to 100 i can TASTE it....

...the tires were very slippery though....i am curious to see how they react as they wear in...I will also be redesigning the vertical stabilizers....

99 4 mph (0 min 24 sec)

BoostCrzy · 03-19-2009, 11:22 PM
