I've seen plenty of RX failures and I saw a 40% edge fly off and plow into someone's house because of a TX failure. Saw no less than 5 losses of RF link last time I went to SEFF. Lets please not pretend that classic radio systems are flawless, lets not put our head in the sand like ostriches. Have have always and will always use 2 RXs in my 35% plus planes, and I know several folks that landed on one remaining RX. Are things more reliable now? Sure. Are they flawless? Far from it. All things man made will fail.

Please remember that a sample size of 1 is not statistically significant. Too many people out there don't wear helmets and seatbelts because "nothing ever happened to me."

Yes, although I've been flying on 53MHz since the early 70's, so most of the silliness that has gone on left me unaffected.

2.4GHz is a mess for a lot of reasons (not related to RC), but it is still as safe flying 2.4 as it was flying 72MHz, except you don't have to wait for the pin

I was just wondering if RPM for a gas engine with an ignition could be monitored through the signal from the ignition in the same way an electric motor RPM is mesured.
The signal or what is monitored might be different but wouldn't it be more precise then light interuption by a propeller?

Yes. In fact the question was asked about a week ago. I quickly Googled it then and found a post on RCGroups on how to use the brushless motor rpm sensor to read the RPM signal from an ignition unit.

Is it possible to use it with the Jeti telemetry ?

Yes. It was the Jeti sensor.

I tend to type very little when I'm using my phone as it is very slow and hard work. I just search for stuff as usually been asked before as was this.

https://www.rcgroups.com/forums/show....php?t=1499121

Came top of my search when I answered this question previously.

I saw your post on helifreak. now added to my ignore list. I usually take quite a bit of time out to help Jeti users as I've learn quite a bit from others and trial and error.

I will stop wasting my time and leave you all to it.
