Id guess 20 to 30 laps , on Niro , 15 % . AT A GUESS .
the ' Range Brews ' could double the laps , so say half of 70 ( laps ) on 10 % Nitro . = 35 laps . on a good day .
So posably 20 laps on 20 % nitro , with a head wind .
.
with the One Ounce 30 cc tank .

Building a Long Gone VI my humble self at the moment .

Lot of stuffing around , solid wing , for the internal leadouts etc .
Dunno if the OS 30 , H 29 R , or ST 21/29s going in it , yet .

p.s.
It might be easyer to fit one ounce in a two ounce tank , than fit two ounces in a one ounce tank .
