Re: Active Hobby Toyota GT1 body

I don't think anybody in the U.S. stocks this body. RCMart says they have it here:

Jason, I appreciate your honesty about the car and after seeing all the support you give on various forums its what I expect from you and I see it in every post you make. I guess what I'm asking is will the car handle better with the 4 cell vs. the lipo tray with lipo battery.

Thanks man,i really appreciate it.

The cars will handle very close to equal with a weighted lipo tray. The lipo car will be a little more of a handful given the higher voltage but they should handle similar. This is based on using a 13.5 as a mod motor. The 10.5 and lower wind motors with 7.4 volts is not efficient. I know people run them but they are extremely hard to go fast with when you are always competing with wheelspin and spinouts. Unless the track is so large and such high traction that anything less looks slow, you wont find yourself running lower than a 13.5 with lipo.

i've not claimed to try to compare 4cell and lipo using the same motor. we all know the numbers don't add up. I would run a 17.5 or 21.5. if it works on the oval then i'm sure it can't be all that bad.

gotta dust off my pan cars!

anyways back on topic. Its really good to see the interest people have shown so far.

The comparison between lipo and 4 cell will arise when they are run together. Low wind motors and 4 cell will beat up on 17.5 or 13.5 lipo car. I definately want to see lipo work well because i think it will help the class. It is tough though being that TC and offroad already run 6 cell so the cars dont suffer as much being they are designed to run with that kind of voltage. The transition for them was much easier. Pan cars havent been designed to run 6 cell with todays motors. They already dont have enough weight behind them to plant the car. If people are willing to buy Pan car specific motors then running a 17.5 or 21.5 will work great. We will still need to weight them to a similar weight of 4 cell for them to work good.

I started testing my modified Pantoura chassis, BMI 12R rear pod and Dampener Tubes, running a 3250 Core Lipo mounted on a Lipo weight plate, Novak GTB 13.5, 17.5, 21.5 combo, BSR Pro Purple front, Pink DBL Pink Rear, Jacked 1/2 front, Full Rear, HPI Porsche Body. At Seattle Indoor Raceway Carpet Med-High traction.

Basing the handling of the car to the Stock CRC Pantoura that we ran for 24hours world record with a mild Hacker mod motor. Fast lap of 8.2 sec.

13.5 is fast, real fast, 9.5 sec laps, during free run on the track is comfortable and just plane FUN, introduce other cars of diff speeds, Mass brake, and counter steering input and 100% attention, passing was difficult (tight track layout) 10 min run.

17.5 was only 2 to 4 tenths slower, during free run, but 5 tenths faster with traffic, absolutely a BLAST to drive, and drive fast. 15 min run.

21.5, was smooth, but just not enough kick, ran about 5 to 8 tenths slower than 17.5 free run, but this time did not gain any during traffic, with out the bottom end of the 17.5 overtaking other cars was much harder. 15 min run

those motors are already standards by roar and/or the oval crowd. *shrug*

jaybro's right. it can only go so soft. "standard" .16 and .18 springs just don't hold up under dynamic weight let alone static. you could design a cantilever type of suspension you find on most open wheel cars but that ends up being more weight and more things to fix. i thought jaybro had those new springs. maybe he can make a trial set in 16 or 18s *shrug*. your other choice is tire compound and that only goes so far as well.

Basically it comes down to literacy to read the speed control and radio manuals.

I am thinking of the majority of TC guys and 1/12th guys who will be running them. I know some guys have a 17.5 from that being the new stocker but 21.5, thats gotta be painfull to watch in TC. Im sure a few of the oval guys will have them but most TC and 1/12th guys wont. I think a 21.5/lipo,17.5/lipo will both be killer classes. 13.5/lipo is getting to the point where we will start feeling handling losses.

The springs we make and that come with our car are linear springs. They are softer throughout compression than an AE spring and are a tick softer off center due to the larger diameter. The great thing about them is they do not collapse. I preset each spring to there finish length. I feel if we go too soft, there will not be enough force driving the tires to the surface. We will get everything figured out in time. We will just need to figure out what the standards are going to be as far as voltage and motors.

Im definitely liking how things are looking for this class...we have a it on one of the largest stages in RC right now (IIC) as an official class, we have a number of guys who have been testing and have been running these cars at their tracks, and people are taking notice (and so are companies as you can see). This is going to be a fun summer

well since i'm running a lipo pack i'll need to add 80g of weight to equal a 4 cell pack or i'll have to add 240g of weight to equal a 6 cell pack. which of the weights would you add for a brushless 10.5t car?

It really depends on the car. The layouts that work best seem to be 4 cell layouts. I would weight it to the weight of a 4 cell.

just for reference i run a wide car with an orion 3200 lipo and added a little over 5 ounces (all in equal placement to where a 6 cell pack would be).. almost enough

Matches what I had to add to my I-Fource!!!

Car is still not as planted as the C10X, but it is making progress on the carpet. More testing this week!
