Speed Passion V3.0 little sluggish in B4

I use the same setup as Gaz ... works very well and is silky smooth compared with LRP / Novak systmes I have used.

sorry to go off topic slightly, but I had a couple of gains of sand inbetween the teeth on a plastic spur and it killed my metal pinion

I find a 78/24 with a 7.5 in a Kyosho Lazer FS (2.5) and the motor is cooking, that's after backing the timing off too. However don't listen to me as I think it's just me that has this problem...

Ran 78/23 and it was better this week, but still too warm for me.

Mike, as I have mentioned to you before I run 23 or 24 against the kit 78 spur with a V3.0 6.5 in my FS and yes it is warm but still in the sensible range!
I have also run a 5.5 in there on a 21/78 and that is ok too.

Check how much air is getting to the motor, FS shell is quite enclosed.

Ordered a 78/25t
