RCGF 120

I like 'em "BIG"!
Just in from flying and cleaning up. The RCGF 120 actually performed quite nicely. I got in three really good long flights. Even though the wind was blowing (go figure) pretty hard, I still managed to get a real good idea of how this motor is going to do. First flight, just a tick more pull out than my well broken in DLE 111. By the third flight, she was launching out straight up at missile speed.

It starts about like any other motor. 4 with choke. (Religiously) 6 without. I expect this to get better as she breaks in. Which from what I can tell already, is not going to be no 1-3 gallon DLE break in period. By the way she appears to be running and comparing it to my 3dubs, I'd guess between 3-5 gallons would be her final wake up call.

Stock exhaust and 28x10 Falcon started out at around 6500. I can assure this. She's well beyond that now.

I have photo's of the install along with some recommendations that might help. I'll get them posted shortly.

So the install of the RCGF 120 was pretty straight forward. Nothing really out of the ordinary. Other than the throttle arm that needed an addition. But no problem when ya got pieces parts everywhere from various other hoopties. I used a cut off control horn from my behemoth Yak when I did the restore on it. It just so happened it gave me the exact angle I needed for the throttle. The inlet nipple on the carb needed a little twist to put it where it was more user friendly. And the exhaust bolts for the mufflers are pretty much like the spark plugs that come with all the Chinese motors. I use them for shooting baskets. Litterally....the trash can basket. LOL.

Other than that, it was pretty much just measure, bolt and hook up. Nothing spectacular. I did use the cowl from the DLA 128 4 cylinder adventure though. It already had gaping holes in it and I figured that if I didn't like the RCGF, at least I still had my perfectly good "UNCUT" cowl that housed the DLE 111 with cans.

Now that I know this 120 is some kind of little power house, and I do like the fact she (the Edge) lost almost 2 lbs. in the motor swap...(dumped the cans....LOL) I will probably go head and cut the new cowl in a more professional and precisce manner.

I have been so anal and critical about my planes' looks. I just need to get over some things huh?

I can honestly say this.... I am very hard to impress since I have been so 3w spoiled. With the dependability and the power and the overall ease of how they run....I just didn't think I would be happy with the RCGF. Especially since I had already tried the GP 176 EVO and the DLA 128 4 cylinder. I was not so sure another "off brand name" motor was the ticket for me. But I do like doing things different. The RCGF 120 is actually quite the beasty 120. It ran good all three flights today. Sounded good. and oh so much more ponies than the now 26 pound Edge even needed. Well, not true. All those wicked and insane things the Pilot 107" Edge does? Yeah, they are even more wicked and insane. If I ever..."EVER" lose this plane to an incident...it will immediately be replaced with another Pilot. No questions asked.

Enough already.... here are some install photos. I will try to get a flight video next time I am out. All I can say with todays flights is...damned impressive motor and plane combination.

If any of you would like to know more or have questions, please don't hesitate asking. For those of you looking for a new 120cc motor that is not only user friendly, dependable, strong as an ox and economically priced, you might toss the thought around with the RCGF 120. I can't and I won't endorse or support nor hype up a product I don't like, have problems with or overall completely discusted with. The RCGF 120 is going to be a motor to shake up the 120cc class for sure.

Get hold of Chad at @Taildraggerrc. He will get you set up for sure.

WTF??? You said photos, nothing about a book!!LOL. Now I'll go back and read it.....He He!
Ok, now that I read it. Sounds like you had a nice experience, that is good to hear. The off brands are slowly catching up or at least worth every dollar and then some. That cowl don't look so bad, with one eye closed anyway. The stock style muff don't do much for muting sound so I have been running straight headers for a while and for the most part they are not any louder.

I'm tickled pink that your 120 runs just as well as Chad's and Diggy's, Rob. Mine, not so much. I think I was more amped up about this engine than you were.

Not sure on mine, but 3 mins into the first flight, she locked up tighter than a snare drum. Not hard on it, did 1 vertical pull at full power and 1 short downwind blast, just after take off. Idled great, transition great, no burble, high end sounded awesome. It did try to take my hand off 2x, but fortunately, I flip hard and fast. Almost sounds like some preignition is happening.

Oh well. It happens to the best of them anytime, any place and any engine. No collateral damage, so that is the nice part. It will be a few weeks before I get the engine out and back.
