Your Price
$525.00

Hi Quality CH CDI 7 Cylinders Aluminum Box and all Aluminum 6061 RED Anodized Hardware used to convert the Evolution Engine 7-77.
First introduced by CH Ignitions in February 2014
The Kit includes now all the tools and hardware you need to convert the engine .

This conversion is one of the best option if you want to keep running on Glow Fuel or any other ignitable fuel.
Once converted to CH CDI you can run pretty much any fuel type you can mix.
You can run  ZERO Nitro if you want to stay with GLOW FUEL, this will be a more economical option.
By running ZERO Nitro the internal components of the engine will be more protected from rusting.
After Run Oil will still be a good  practice.

By Converting to CH Ignitions Glow CDI you will get a better Idle, better engine behavior all around and up to 25% more run time on the same tank of fuel.
To accomplish this you MUST LEAN (turn in) the needles 1 turn at list BEFORE you attempt to start and go from there.
Fuel will be burned out 99% and you will not have to clean up the messy Glow from the plane.

  • GLOW Spark Plug GAP 0.35 mm / 0.0135″
  • No more than 15% Nitro
  • Must use 7.4v 2 cell LIPO 2300mah minim 2700-5000mha

Fuel will be burned out 99% and you will not have to clean up the messy Glow from the plane.

We recommend that you grease the front end of the engine by taking OFF 2 push roads and the lifters holders and pump some good grease until is all filled.

Adjusting the valves we recommend to adjust the same cylinder 3 times before you move to the next cylinder. Set the gap first then rotate a full revolution until that cylinder comes to the same point again, check the valve lash  If is good go one more time and check again.
Inside the front end are 3 sets of cams at 120 degree apart and some times they will wear different.
If you set by the worn OFF VS a better you may be too tight or too loose. You will need to find a happy medium that will work the best.

When you tight the spark plugs be careful; material is weak and you may strip the thread.
I can fix them if that happens, I have special inserts for 1/4-32 threads.

USE 20:1 mixture 50 ml oil to 1 L Gasoline    6.4OZ to 1 Gal . I run Morgan OIL CP14, also Evolution oil from Horizon Hobby or other supplier in your area.

When you first set it up will be best NOT to use the EXHAUST collector ring, this way you will be able to see what every cylinder is doing .

We also offer full install and test run Service for a flat rate of $100 ( 2 hour labor) and many times we go way over 2 Hours.
