I’m just about ready to publish a post on my views on teh way ahead for us in Qld re motors, batteries, weights etc etc. If you want to know my opinions watch this space.
For the moment let me just say this – today at BAyside I ran what ROAR have approved for stock racing in the USA alongside the 27t brushed. A 17.5 sintered rotor brushless.
Using exactly the same setup as last fortnight, same battery, same track, same hot summers day. I recorded virtually identical laps as I did with a 13.5 bonded. As quick as any of the brushed motors in accellaration and top speed I reckon and virtually line ball with the other bonded rotor 13.5’s that were running today.
The selling point for me was that on every run it was about 20 degree (F) cooler than teh 13.5 bonded.
I haven’t played with ratios yet – just ran teh Novak recommended ratio and it seemed right on teh money.
More tests to follow.

Thats interesting and re-assuring Heavy.
I was expecting the 17.5 it to be slightly slower than the 13.5 bonded based on forum chat over in the USA. (more simular to the tamiya sports tuned black motor)
It will be interesting to see if the stats are similar between brands (Novak, Speed passion, Lrp etc)
Just like with brushed motors, there is likely to be one brand better suited to open fast tracks and one better suited to tight technical tracks etc.LikeLike

I think they will all be more similar than brushed motors. I think the 21.5 (Novak or Speed Passion ) is the same speed as a Sport Tuned.

Its a big plus in my opinion that the sintered rotor will be allowed in the not too far future (here) as it has a way better drag brake effect , way more close to what a brushed stock motor feels like to drive :))

Paul you obviously know more than I do in a couple of areas – not sure it will be allowed here in the not too far future and when you gear a motor at 56mmpr it has a serious affect on drag brake – maybe your test was on a different type of track to my test – I’ll focus on the drag brake effect next time I test just to make sure I am not missing something.

not too far future i meant like one year away (in my opinion 1 year is not that long 🙂
also i tested a 13.5 sintered & a 13.5 bonded,
and the sintered had way more drag brake effect even when you put the drag brakes on the max setting of a gtb with the bonded. the sintered motor still seemed to have more (esp once they were warm)
so i assume most sintered rotor motors (novak 17.5ss included) would have a better drag brake.
did you try and run the 17.5ss with full drag brake setting of a gtb????
on another note, the old gtb was better for the bonded motors in my opinion as the drag brake setting went to like 50% and the new ones only go to 27% which is all that is needed for sintered.LikeLike

My ideas will progressively appear on the soapbox. This thread is for your comment should you wish to make one – it will be published if not abusive, durogitary, or containing foul language. In other words this is your soapbox but keep it nice.
