Kiwifyer - good news man, but on site bissonmufflers have all silencers and NO just the rcg 20cc! I bought the 26 cc silencer, it's the same offset thar rcg 20cc. Thanks!

Well done, I get most of my mufflers from this site and they are really well made.
 Kiwifyer 45 points
It is a pity that HK do not give more detail about their own mufflers. Its like looking for a needle in a Haystack.

Where is the Rear Exhaust version of this motor please? Ideal for narrow warbird cowls.
William  1 points - 4/13/2016
The "F" is not for a radial mount and "B" for beam mount. "SBM" is used for beam mount. RCGF is the brand name. I don't know why HK uses RCG unless it isn't really a RCGF. Check the RCGF site for the info. https://****rcgfusa****/ or ***********rcgfservice****/

I´*d like to know the difference between RCGF and RCG?
 Paul 15 points
Same engine, both RCG the 'F' is the radial mount and the 'B' is the beam mount, really good motors, I can recommend both, the 'B' 20cc is a lot more powerful than the 15cc 'F'.

I loose the muffler of my engine (rcg 20 cc)....please, somebody tell me where I can buy another? I was looking for and have no find... thanks!

sales*bissonmufflers**** They can custom build any muffler for any rc engine. And make it quieter than original if required.

Look under the Muffler & Silencers Cheers Jimbo

No luck Jimbo, No standrad RCGF 20 cc muffler listed on HK site. This is why people go to Bisson Mufflers.

1 thumbs up!
I have received this engine. While I give only 4 stars (for the reason that yet I do not know as it will work on my model) The motor is not copy DLE-20 though who that thinks that they are very similar. On height the motor above on 8??. The motor weighs 765 gramme Weight with the muffler and ignition - 955 gramme Weight with the muffler, ignition and Screws/Bolts/Nuts/Engine Mounts which go in the complete set-1040 gramme. I am glad to this motor, it has a good compression at once. The piston has two rings. Though outwardly the motor looks rough (not accurate), but it is well entered in a cowl of my model - Phoenix Models Extra 330S Sport/Aerobatic ARF .61-.91 . But the unique moment - me does not suit the muffler and I could not find to it replacement yet. I hope that HK can provide support to this engine with spare parts. The engine is very good alternative GLOW Engine 90 and its popularity depends on relation HK to that that they sell. While all looks mediocre as have given the description with the big discrepancies which frighten buyers of the not of a correctness.

HK 20cc daul ring gas motor, is a nice clean rear carb motor. With 9,800 RPM and 2.2 hp and ~2 lb. or 1 Kg in the plane, it is a powerhouse. The only thing I did not like is the lack of info and dimentions for the engine. I hope I have solved this problem, by putting detail pictures in the FILES area of this item on this page. I would like to see a side mount 15cc like this 20cc with a 90* exaust for rear, in cowl, muffler mount. A 90* exaust for this engine would be nice too. This one is going into a Top-Flite 1/8 scale P-47 Thunderbolt, with a 64" ws, 1.6m, 12 lb ~ 5Kg.

Got one of these engines and am so far very pleased with it.

There is alot of confusion about the power output of this little engine as many compare it to the radial mount rcg 20, the beam mount is a completly different engine and produces more power than the hobbyking website shows as stated before by someone else. This is a dle 20 copy and produces similar power and weighs about the same.

Mine is hauling a seagull yak 54 at 10lb dry straight up with a 17 8 jen prop at 8300 rpm. This engine produces 14 lb thrust.

So far I have had no problems with this engine but have gave it 4 out of 5 for quality as this engine does not have a walbro carb and I simply have not had it long enough to comment on reliability.

Im that pleased with it I have ordered another.

Engine a little weak on mounting didnt expect a glow engine mount ,so i had to modify muffler to get it to fit inverted .After all the motor runs out great I m running a 16x8 prop and still cant seem to slow it down ,i put it on a 90-120 size yak and it feels like it ripping the wings off . But anyway great product and price for those of us that cant spend big money airplane parts ,it is just a hobby right ? May you all havea blessed day .
