We are proud to introduce our new Nitro-Miser carb inserts.... These inserts utilize a reduced throttle endpoint which can dramatically increase runtime, yet at the same time they have a relatively small effect on overall power...... We have been testing these for the last couple of months and have been having extremely good results....We have seen runtime gains as high as 3 minutes on some engines ..As well we see a stronger idle and a stronger low end and midrange throttle response...The patent pending design of the insert focuses the incoming air directly over the fuel outlet which creates a stronger signal and better overall atomization of the mixture....We will be offering these in a package with 3 different sizes, they will fit OS and Novarossi engine for sure... Pricing and details will follow very shortly

I have one of the pre-production Nitro-Miser inserts and it flat out works. It's easy to tune with it and it does save fuel with no discernible loss of power.

I have my slide EPA set to only open 75% as it is. I will definitely be picking some of these up!

I want a set!!!!

What type of material are they made from?

Derlin.

They are injection molded in house out of Delrin !!!!!! 100% made in North America !

Pretty cool Neal !

NICE.. i have 1 that i made up myself... good work Neal

Neal, would I benefit from switching to the Delrin version or should I just stick with the proto version for now?

you will want the final production version ! it is much nicer !!!
