I get about 10 min on my 76 but i love the power uplines. I also land with 1/4 tank left just for safety sake thats on 24 oz. A 17oz great for 35cc.

Actually I use 14oz on my 35cc and 17oz on my 50 and 60cc. Get 12-15 min. on both no problem, mixed Sport and 3D flying, no XA.

Any issues running the 6.6v IBEC on the 76 ignition? Already have a 6.6v version but curious if I should just do the HV Ibec.

im sure it will run but if voltages drops even a little it will give weak spark. Weak spark== potential deadstick. I run all 4 of my gp engines on 7.2v hv ibecs.

The 76 needs at lease 7.2 volts to the ignition to avoid kickback.Any less and your going to have ignition problems.I switch to rcexl ignition on mine sense I didn't want to use any lipo's.

Pretty Sure Joe Lewis at Aviator Plus pefers to run 6.6v on his ignitions.

I run mine on 7.2 as well. That way when a 2S LiPo voltage drops the output will remain constant. Same idea with regulated down to 6.6V - The techAero only takes the excess voltage out, so it'll still provide power below the regulated output

The old style ignitions did this - I don't believe this is the case on the newer ignitions.

Thanks all, decided to just order the HV ibec and run 7.2v. Not sure how old my 76 and ignition are, got it used

The old ignitions are pre GP76/38 FWIW.
Cannot go wrong with a little extra and constant voltage like you did.

Yeah, I'm running a 1100mah A123 life battery for my ignition. 6.6 volts, gets 8 flight between charges. Runs great.

I just went through this debacle, I can assure you that 7.0v or less and the engine will give you problems (as does a bad connector, but that's a different story for another time). I run 7.4v and don't have any problems.

He told me not to run at 6.6v.

He told me not to run at 6.6v.

I'm running 7.4 as well.

For whatever reason, I remember Joe telling me over the phone that he personally liked 6.6v on the new ignition modules (not the old style) - this was about a year ago. Joe wasn't endorsing the use of 6.6v by any means.
I was going through some troubleshooting issues and we talked about voltage. Ended up changing the ignition and have had no issues a year later.

I'm curious why you assure operation under 7v will give issues. Please explain your experience with the new ignitions and 7V and under is bad. Any info is good info. Thanks

this is from the manual

"Make sure the battery voltage is over 6.6+ when under load"

I was told not to go 6.6 volts because of the potential kick back,

I was also told by Joe to run 7.4 v on the ignition of the 38 and the 76, both bought new this year. I run A123 batteries on my planes, but since he recommended it I went with Lipos on the GP-powered ones.


If one wants to run Life/A123 batteries, another option that others have suggested would be to replace the GP ignition with one from Rcxl or RcXp.

Good info, Thanks guys. I know the older ignitions had kickback issues with low voltage. Sounds like the risk is the same with the new ignitions for some.
Just a thought, a regulated 2S LiPo down to 6.6v on the standard Tech Aero - the voltage will never sag below 6.6v - even under load.
This is the same with regulating to 7.3V on the HV techaero.

If you replace the GP ignition module with Rcxl or RcXp, do you also replace the ignition pickup sensor? Is the stock magnet position ok?
