What brand do you like Josh ?

Not sure. I have two different brands, and they both worked well.

many people are using the Tech-Aero Ultra IBEC... it's an ignition kill as well as a BEC for the ignition...

...over on FG it's getting quite a movement, one less battery, is an ignition kill, just plugs into the receiver... very cool. I'll be using it myself in my upcoming projects.

Hi guys... I'm looking for some advice on my first gasser project.

I took this video on my phone today to highlight the vibration on my 70" slick. The prop is in balance and the motor is tuned just rich enough on the low end to get a good transition. I guess I'm just wondering if this is more vibration that normal or not. I can see it better than you can because of the frame rate on my phone but if you watch you should be able to see about how much vibration I am getting. The motor has about 1.5 hours on it now and I did a maiden yesterday afternoon (flew great!) Anyway, I'd really appreciate input. I may just be over-reacting since this is my first gasser but my feeling is that it is a little excessive. We ran it with an RC exl ignition and it seemed to quiet the vibration down a bunch. The dealer sent me one but I think it is bad since I can't get the motor to run with it...

Sorry for the video also being filmed on it's side

excuse the noob question as my first gas plane will be here in a month or so. But if i am looking at that correctly it plugs into the receiver on one end and ignition on the other. I assume you set a switch on your radio as an engine kill switch.

And i guess you would then be able to run one mechanical switch (i was looking at the fromeco badge switch) with one 3000mah Life pack straight to the receiver to power everything?

If you didn't purchase the stuff already I would go with the wolverine switch and run dual 1500-1800 life batts. The wolverine is 2 switches and a batt sharing circuit all in one.

no i havent purchased anything except for the plane, control surface servos, and engine so far.

I am using the Aero-Tech Ultra IBEC from all of the great reviews on FG and so far it is living up to it's reputation in my 87" Extra SHP. I am very happy with it.

working flawlessly in my 89 so far also.....

Edit : the wolverine is 2 switches not 3 that was a typo.

gotcha...i know the manufacturer is recommending using one 3000mah pack since its only a 30cc plane any reason i should go with two?

Its just a safer way to power the plane and a piece of mind. If one batt or connection was to fail you would lose everything, with the wolverine and 2 batts it is redundancy if one goes the other will still work The wolverine switch isolates the 2 batts so if one goes it don't take both out. I do the dual redundant batts on my 30cc and up.

and if you do redundant batts, you can get away with two much smaller packs. so instead of 1 3000mah pack, you could do something like two 1800 or 2000 packs

Also using only 1 servo type connector to the Rx has a limit of I think 3-5 amps which is not enough for a 30cc planes servos which servos did you get digital or analog.? What Rx are you gonna use?
