Round 10

Anyone else fancy running their 1/12th scales again this weekend? Could be a last opportunity to have a play with a "blinky" setup before the winter season begins (and if anyone has any ideas where to start, I'd love to know :)).

Hope there are a few again Tim.
We have decided to run a 1/12th heat through the winter as long as there are a minimum of 5 cars, which sounds likely from what the drivers said at the last meeting. :)

What speedo and motor Tim?

I ran mine with no boost at 78mmpr and that was LRP Speedo with Speed Passion motor.

I have a Tekin RS and a Novak 10.5. I know they're not exactly flavour of the month, but I'm not going to fork out a few hundred quid on an LRP system which appears to be the one to have for 1s blinky mode.

I'd best try and get some smaller spur gears if I want to get to > 70mmpr :D

88 on 64dp is the one to have

I'd still start on 78mmpr with that combo and go from there

The speedo won't make any difference really, but the motor timing is where you get the speed from in blinky.. somewhere around 65mm/rev with the old fixed endbell jobbies and 58-ish with something like an X12 (2 dot insert) seems to be about the right starting point at the moment.

I only had one run in practice yesterday so didn't have a chance to experiment, but I ran with an SXX speedo and X12 10.5, 2 dot insert and 1s rotor geared at 62mmpr. The infield speed and pickup felt ok, but I did reach full speed quite quickly once onto the straight and managed to hold full power through the sweeper with ease. I would have liked to try a standard rotor with 1 dot insert with slightly lower gearing as the track was quite fast, next time.

It was the first time I have ever tried blinky, and I liked it. I was going round with Tim and there was nothing between us, although I did seem to have a little more infield punch. Think blinky will promote some very close and enjoyable racing and will reward consistency, looking forward to it.

There's going to be a learning curve to finding the best setup for each motor/rotor/speedo combination. I was using a Tekin RS with a Novak motor (timed forward 2 notches from the middle) and ended up with a 68mm rollout. I tried about 70mm and the motor felt sluggish after about 2 minutes although coming off no hotter than at 68mm. I also tried going lower and the top speed was noticeably less.

Blinky does feel really slow down the straight and round the sweeper, but overall, the enjoyment level was high and as Terry says, consistent, tight lines will be rewarded with quick times.

Are we not worried that the emphasis is now on the motor i.e. gearing and timing and people are just going to over gear or over time and blow up 85 quid of motor?

I was too. But as I went up and down the rollout, the temp never got hotter than 60c when the performance started to drop off.

These were the ratios I tried through the day:

Practice: 39p/88s/48mm = 66.83 (really slow)
Q1: 41p/88s/47.5mm = 69.53 (better)
Q2: 43p/88s/47.0mm = 72.15 (sluggish after a couple of minutes)
Q3: 42p/88s/46.5mm = 69.72 (better)
Final: 42p/88s/46.0mm = 68.97 (best)

The final produced my fastest lap, fastest time and the most consistent feel across the 5 minutes.
