I'll try higher ratio's then.

Though in the past they have been too slow. Do you guys use much motor timing? I'm not familiar with the Duo1 so comparing that does not help... I have run the Duo2 & Duo3

Recently ran the summer nats (Fairy Meadow) with 5.4 fdr seemed to work nicely. I dont have another race for about 3 weeks but it will be good to try these things. No permanent track locally does not help.

Have not played too much with this software but just noting my observation that that high of a ratio would lack top end.

Cant wait to try!

Cheers
