Well I ran my new GTB+5.5 on the weekend.... It's my first ever race with mod, ever. I've never owned or used a mod setup before.
Car is an XRAY T2.. with a ONE-WAY
Gearing = 84t spur, 15t pinion, 1.7ir. (48pitch) = 9.52 overall ratio
Tyres = Take-Off CS-32 rubber tyres.
Track temp = 50-55C deg. (basically too hot for CS-32's i needed 37's!)
I have three sets of CS-32's left over from the states where I ran stock. They had only 3 runs ea set on them, so figured I'd use these)
Went out for a practice, and instantly discovered I had to severly change my driving style. I quickly learned that the car would spin out pretty badly if I fully backed off the throttle on slight cornering (due to GTB's default drag-brake setup).
I was going to dial-down the drag brake when another T2 driver recommended I fit my spool in the T2 (for a solid axle) as he is running. As soon as I did that, WOW.
This thing is fast. damn fast. scary fast. Our straightway has a curve in it, like a sweeper which is a large 90'deg. I was too scared to hold the throttle for the length! I think I used full throttle in the races only a handful of times. FAST.
after about 10 laps (track average is 17-20 laps).. my tyres were GONE.. they'd gone totally off.
another racer suggested I 'look after my tyres when racing mod'. I think what he means is. dont be so trigger happy all the time. Coz this thing just light's up when you nail it. full on.
In my first race, I started to get what felt like glitching, I'd loose my steering/throttle for a split second. I use spektrum, I'm wondering if my rec isnt getting the voltage it needs and it's resetting on the track. Perhaps I need to install the cap for it now. dunno, never experienced that in stock.
I run brand new IB3800's, matched. After each race, I was coming off the track and discharging straight away. I was getting up to 2300mah out of my cells AFTER the race!!! on the discharger! 2300!!! I couldnt believe it. That means my GTB/5.5 is using around 1900-2000mah on the track. WOW! only half the cell pack's capacity. Seriously this is about what my brushed stock/GTX setup was using... I cant believe it. I'm shocked.
my results, for my first ever mod race, 3rd, 2nd, last (broke a suspension part) 2nd overall for the day. Not bad, for my first outing in mod class.
I'm actually the current 'stock' State Champion...
I feel like a begginer, learning r/c all over again. what a buzz.
My motor (the 5.5) was coming off the track really really hot, almost too hot to touch in some cases. the GTB was fine. track is pretty tight, and technical. Some guys were suggesting I gear it up a little more, but I didnt really even use full throttle, and I was running a couple of pinions down from what some fellow racers were running.. I felt it was ideal
This w'end... foams, a different / massive track, more gearing... cant wait!
