CH IGNITIONS CHXL SYSTEMS
We have come up with a few new things about our
CHXL ignitions.
First we are very pleased with our CHXL
ignitions. We have sold over 2000 of them, with two coming back with problems. One was a 10
MM-System for the NGK CM-6 spark plug. It had a leak in the silicone
spark plug boot to ground. We repaired this and returned it to our
customer. The other was user caused. One of the male pins on the Futaba
plug had pushed to one side and missed the female pins. If these plugs
try to bind up and will not push together easily, look at the male pins
and align and center them with an exacto knife blade.
There are fliers who still have problem
getting the steel cap off
the
spark plug. READ OUR INSTRUCTIONS. Insert a small 1/8 wide flat screw
driver between the steel shells and turn it side ways and pry the cap
open. The cap will then come off easily. You may need three hands to do
this. DO NOT use pliers on the steel cap this will void the warranty.
Besides it makes it look bad.
We have already gotten ignitions back
with the steel cap ruined and spark plug wires ruined by rubbing on
something. I have been preaching this for over 30 years. Protect the
spark plug wire any place it can rub on anything. Use some soft vinyl
hose or vacuum hose. Slit the hose and put it around the spark plug
wire and tie with nylon ties. AT least 50% of the units we get back for
repair have ruined spark plug wires. Remember the spark plug wire is
not replaceable on the CHXL or RCEXL Ignitions and many others. This
kind of damage is not covered by warranty. This is improper
installation.
We will do repairs on RCEXL and the CHXL
ignitions that are not
covered under warranty. This is limited to wires outside the case and
spark plug boot and cover. We can replace the braid and heat shrink but
we cannot replace the spark plug wire itself. We can also shorten the
spark plug wire. The customer will have to pay for shipping to us and
back.
The early RCEXL ignitions have a sticker that
says 4.8 to 6
volts. Six
volts was two much for some of these systems. The newer versions of
these ignitions have a sticker that says version 2. These are OK with 6
volts. I read on R.C.U. that some of the fliers were using two of the
A-123 cells on the RCXL ignition, these cells hold 7.2 volts for quite
a long time. I have tested these ignitions with this voltage and the
case gets fairly warm so transistor has got to be running pretty hot.With 7.2 volts
the battery drain is over 700 MA You are on your own if you use over 6 volts, any
damage caused by over
voltage is not covered by warranty. I have been flying the CHXL single
ignitions on one Li Poly. This seems to work fine, the engine will
start cutting out before the voltage gets low enough to hurt the single
Li -Poly. Just do not forget to turn the ignition off or it will ruin
your single cell.
Many of the Chinese engines are coming with the
RCEXL ignition. I do
not think many of them will have ignition problems. Some of these
engines are good some have problems. If you catch me in a weak moment
we might do a make run on one of these engines but I doubt it.
We will not get involved in doing R&D on
the Chinese engines.
Some of them have version one two and three or more.
They keep getting
better but some still have problems.
