Hey RACJ, try it yourself. Put a decimal in front of the .820, multiply it by 2.2, = 1.804, then multiply by 16, = 28.864 Oz.

So I'm messing around the web and notice HobbyKing has started carrying the RCGF 26 and 50. Listed there as RCG but the CDI in the pic still says RCGF. $210 for the 50, $140 for the 26. Anyone here have HobbyKing experience?

My 45 rcgf is right around 7200 rpm with a 20x8 zoar prop. I feel there is still some room for improvement here, this is my first gasser and still learning....You have to love these engines, user friendly , and no need for a $200.00 high torque starter to get them going...

Hey Cold_reboot

They are definitely NOT rcgf engines. The 26cc in their photo has the spark plug directly vertical in the cylinder. The performance is suspect too.

The 50cc is definitely NOT a rcgf engine too. It has a cast crankcase. The rcgf has a cnc'd crankcase.

I personally have never heard of RCG, or their engines. To me they are another cheap knockoff fly by night, clone engine, and they can be nothing but problems. I have had LOTS of experience with the clones.

Also.... if you have problems with the engines.. who are you going to call? No matter which engine brand you buy, just consider buying from someone in North America, that you can call for help and assistance. Not to mention someone who will speak English to you.

Price of the engine should not be your overriding factor in an engine purchase decision. Another thing to consider is that manufacturers - rcgf included - build similar engines for different markets, with some very different engineering designs. For example their engines for local consumption are much different than the engines for export. They are cheaper (lesser quality components to get the price down). This is a standard business practice in China with most manufacturers. That is why for example our Aerovate engines are made to our specs.

I buy a lot of electrics from hobbyking but I have not bought any engines from them. I don't think I would, once you buy from them your pretty much on your own, if any problem arises getting service is a b!%$h. The price is always right though...LOL.

This is the part where I get to make a "Ghostbusters!!!" joke before anyone else. Yeah I was actually planning on getting the RCGF 62 for a giant scale ME109 that'll be a winter project. Might as well get brought up now before it gets brought up later. Not that anyone will go back and read page 151 or whatever we're on later on when it comes up again. How do you like your 62 T3? How many pounds is it pulling these days?

Last I flew with it I was at about 30+ average on the Can muffler, I had a run in with the tail of my friends truck a while back and I haven't had the time to get it back up in the air, its a great running engine, and very easy to start... I've been busy flying Helis lately. I got into the 450's then jumped strait into the .50 size ones! They cost, so most of my hobby funds were diverted to them. I'll be getting back to the Gaint scale scene pretty soon, got to get all my buying out of the way before my kid gets here....

Hey Cold_reboot ,

Thanks for the information.

For our factory produce some old item engines for our local market,we sell the old item engines to model shops ,airplane factories and trade companies in our local market. The 26cc engines in hobbyking's website seems like our old item. But we haven't seen the 50cc engine before ,we don't know why there is our CDI Ignition beside it.

Now our abroad market engine items are already very different from our old items ,no matter in performance and also power. But for we know that hobbyking do affect a lot to distributors, and consider our distributos' profit ,we will still check for the issues here and try to control our local market. We will reconsider for our local market selling way. Please give us some time to check for it and then solve the problem .

Best Regards,

I would buy an engine with local service for sure. Your not saving all that much by the time you figure in shipping and you are not supporting your only known support, your local dealers. I do buy electronics but thats it, and buy a few extra's because if things break, its not worth sending stuff back.

On another note, I don't know how this plane flies but its a great price for an airframe for the 26cc.

Even better with the 28!

OldFart1

Considering pretty much everything ModelTech offers comes in substantially heavier than advertised, I'd have a 45cc waiting after the maiden

High 5 to the 28cc !! I like the looks of the plane but have never built a Modeltech.

Johnny,

It is encouraging to me that smaller engines are in development!

Having said that, the 90 mm height from the prop shaft to the top of the cylinder is almost exactly the same as the RCGF 26. This, coupled with the fact that the new 15 apparently will have a vertical spark plug arrangement, means that it will take more room to mount the little 15 than it does the 26 (which of course has the spark plug at a very shallow 30 degree angle.) Since the 15 will be in smaller planes, I forsee that the spark plug will protrude a lot from most installations.

If it is not too late in the tooling stage, I would STRONGLY suggest that the 15 use a cylinder with a 30 degree plug!

Just my opinion.

Regards,

Randy Little

Hey Randy
GREAT points of view on the cylinder and spark plug orientation. You can be sure that this and other comments sent to us via email are being sent to the factory for their analysis.
We are all anxious to see the real world performance specs on this one too. Hopefully they will have some engines ready to ship to us for testing shortly.

Cheers

ModelTech Yak - I have one off these. It indeed turned out heavier than advertised. With the 26cc, the all up weight is over 11 lbs. This is 10% over the 8 - 10 lb. advertised flying weight. The 26 flys it OK. It will hover it with no climbout to speak of. The plane flys heavy at this weight. It is a good buy right now. Hobby People has it for $150. It needs a gas engine that is less than 40 oz with the ignition battery. Let me know if you need more details. Bob

I finally completed the set up of my RCGF 20cc engine on my Seagull Ultimate. I've put the elevator servos in the rear under the horizontal stab so to balance it I had to mount both the 6v receiver battery and the 4.8v ignition battery up front. I changed out the throttle horn (maybe RCGF should start doing that with their new engine designs ;-) ) and put the choke on a servo that I hooked up to the retract switch. Take a look at the pics and let me know if anyone can see any problems with my install.

Also, is there any reason NOT to use an electric starter when starting this engine???

Skip, The 26cc is an RCGF purchased from Jim Willis (Agape Racing, Mechinicsville, VA. A local dealer for me and he advertises in this forum). I have a 1600 mah Nimh Orion pack w/ a Smart-Fly reg) I had a 12 oz tank. I was frustated w/ the way it was flying, so Sunday I took all of the gas stuff out and replaced it w/ a Saito 125. This required moving all of the servos forward, but the forward servo mount was already in the plane. It now weighs 9 lbs 6 ozs. Still does not have any real pullout ability. Flys much better at the lighter weight. Will post pictures a little later. Let me know if you have any other questions. Bob

CONNERY,

I would be very interested to know how your Ultimate flies with the 20cc engine for I have the same aircraft and was thinking of either the 20 or 26cc engine. Looking forward to an update.

Q500RC

I'm not sure why folks would want to run a 20cc or 26cc anymore now if your buying new. Unless you already have one of the smaller cc engines on hand thats a different story.

Henry and AussieSteve having come up with the new 28cc engine thats just as light as the other 2 engines and more powerfull! Also I don't believe there is much difference in the footprint either.
