RCDENT,

In-Flight Mixture Control ?

I think we must talk about:

In flight mixture adjustment!

The picture is of my Webra Speed with mixture adjustment by radio control used for a tuned pipe.
My problem is with this system it is possible leaning an engine without knowing the temperatuur.

For the normal exhaust I prefere a pressure controller on the fue linlet of my carburator (like a Cline but I use my own design). and also a pressure controller and exhaust checkvalve on the fueltank. Both of these controllers I use to get a mixture as constant as possible.
A Cline you can buy.
