I've been flying glow for 7 years and now considering buying my first gas engine. I've had my eye on the GP Giant Aeromaster for sometime now. Tower recommends a 30-60CC engine. There's a lot of good information and happy R/C'ers flying the Brillelli engine. I'm a bit confused with the sizes though. Which Brillelli would you recommend?Also,,,,can someone please explain ignition to me. How does it get started?

Well it has a pretty large engine range.... really depends if you want scale flight or some power for mild acrobatics?

For scale you would be fine with the Brillelli 46.

I did some research (I dont really know that plane) and there are a fair amount of guys flying them with G-62s. The nice thing is you can always throttle back so if you went with the Brillelli 50 or the 366GT you would have an engine that would work in a broader range of planes down the line.

If you want acrobatics I would def. grab the 50.



Ignition is battery operated. There is what's calls a HALL (sp) sensor and a magnet on the back of the prop hub. Everytime that magnet and HALL Sensor pass eachother it triggers the spark.

A basic outline for starting is simply close the choke, go to full throttle, with the ignition on and start flipping. Flip it till it pops once (tries to start). Then go to idle and flip 3-5 more times and she is running.


Hope this helps... I'm off too go play with my GT 366 and 46 right now

Sinergy,
I fly [2] Giant Aeromasters on the Arf I use a 3.2 Sachs and the built one I fly a 4.2 Sachs. Both fly well. For really hot dogging it the 4.2 is the way to go. For sundays flying the 3.2 does the trick very well. Any good 50cc engine will fly it well. One I crashed
had a US 41 in it, flew ok but not to much verticle. I have had [3] of the Giant Aeromasters. Really my all time favorite plane, and I have 13 Giant planes, from 70" Yak to a 35% Extra 330L.

cruzomatic,

Here is a video of jstanton flying the GP Giant Aeromaster with a Brillelli 40cc.

If you want to fly the Aeromaster as it can and should be flown, take the advice provided here by those that actually fly the plane and not Tower. I agree with the 3.2 and 4.2 installations in most cases for the Aeromaster.

Silversurfer is on top of things. If it were me, I'd get the G62 and let Ralph lighten it up and put EI on it and have a blast. My G62 is such a sweet running engine. I've been running a XOAR 22X10 prop and just got a Top Flight 22X6X10 prop to try. I saw one of these props in action at our Warbird meet and it was very impressive.

Cruz,
Nice to see you are getting into gas, I think you'll like it. I went through the same thing you are going through just a few months ago. I wanted to get started into gas and had no knowledge and no one at my club flies gas. I spent alot of time on this board reading alot of posts until I felt confident enough to make a purchase. I bought a Zenoah 62 that was lightened by RC ignitions. The way it was lightened was by converting it to electronic ingnition. I feel that this is a must (electronic ignition). Most manufactureres now have at least some if not all their engines running on electronics. Going to electronics does make the engines lighter and easier to start but requires an extra battery and a kill switch. All of the top pilots using gas fly electronic ignitions. Another thing to consider is the chances of RF interference between the gas engines and your radio. there are ways to isolate the interference and there are tons of posts on this subject here to read. I am not going to state my favorite engines nor what brand the other two I have since purchased, I leave that up to you when you go through RCU. here you will find opinions pro and con on virtually every mfg. What I do recomend besides going with an electronic ignition is to buy from a reputable supplier who can not only answer your questions and who also gives you good support down the road ,especially your first gas engine.

Same here on getting started in gas a little over a year ago. There were a couple guys at our field that flew gas but I didn't get to talk to them as much as I would have liked to so I turned to RC Universe for help and got lots of it. Gnirwin is right about making sure whoever you decide to get your engine from just make sure it's a reputable dealer. Lots of nice engines out there with good support so you just have to pick which one gets your business.

I have flown the kit built version extensively .... first with a Zenoah G-45 that was later changed to a G-62. These planes have an incredible amount of drag, even for a biplane so the G-62 version is anything but overpowered. These airplanes like a big, low pitched prop for best performance and it takes cubic inches to turn such a prop. My vote would be for a G-62 in any version or as was asked, the Brilleli 366 would seem perfect. Certainly any good 50 would also work well ... just depends on what kind of vertical performance you want. Regardless of engine choice, you will have a very pleasant flying biplane that is anything but fast.

Thanks for the replies guys. I've been looking at the Aeromaster for a while now. Just a bit apprehensive about getting into gas. I guess I felt the same way about getting into glow coming from electrics. Thing is, I fly with a couple of glow guys who helped out a lot with the electric/glow transition. No such luck with gas as there's no one around. If I go with gas, I'll be asking for group hugs and all as I'll be here asking a lot of questions. What confuses me already is you all saying to "ask" to lighten up the engine. Not sure what that means? Also, running an extra battery is not a bid deal, I could swing that. How are these engines started. I'm used to using my trusty electric starter for all my glow engines. I'm assuming a thick leather glove or chicken stick is in order?

Zippi, thanks for posting the video link. Man, that's a sweet looking plane. I just maidened my GP Super Skybolt and now want the Aeromaster. Go figure.

Thanks for chiming in guys. Soft landings,,,,

cruzomatic,

There is no difference in asking your buddies at the field questions are asking your buddies here questions about getting into gas. I used a lot of help here on RC Universe and got through it just fine as you will. Basically you just take your plane, gas can, and a few tools that you may need and thats it. No starter for the engine. You flip start a gasser so get one of your winter gloves out of the closet. What I was talking about when I said to lighten up the engine was if you buy a G62, you can send it to Ralph ([link=http://www.tompierce.net/190/html/building/RCign.htm]RC Ignitions[/link]) and by converting it to EI the flywheel will be removed that will lighten up the engine.
