why lock in 2nd and not 1st?

[Mark Fradkin]

I am unclear as what is considered 1st & 2nd gear. I have a flm case and
at this point when the servo pulls out the bar extended outward my gears work. When it is in all the way it does not work. What gear is it considered when bar is extended. I built this Rc monster inspired emaxx from almost scratch & aftermarket parts. I did however start w/ A emaxx trans.
12020/8xl w/18 gp3300 in series, strobe set up. When it did sorta work(bar inserted) It
seemed like a faster top speed.

Thanks ahead of time to you gus on this forum as RC Mike ad you are great information in this hobby
