It seems some guys are interested in a big blokc for the Knight 3D, I also see they are making Mods for a Pantera big block. Here are some pics of my YS61 in the Knight 3D.

sweet thanks

are you using the stock clutch system?

i wish they would come up with a lower gears like 8.27

what are the flight times on the stock fuel tank?

have you stretch it yet ?

i bet with the 8mm spindle running 690mm to 720mm should be no problem

what is the weight ?

I was thinking a ys st61 or os 60 wc I have both?

Not sure any advice would be a help! I would like to change my gear to 11 or 12 tooth pinion? 12 seems a little high though. I dont have my calculator handy 87 spur 11 is like 7.9 to 1 ? that would be 15000+ for 2000+ Headspeed? roughly?

I've tried both the OS and the YS I like the YS, Yeah you have the cut a piece of the crabk shaft off bore the fan hub and tap I beliebe it's 8mm you will also need to drill two new holes in the engine mount.
