Oi Wesley, eu uso gasolina podium com oleo motul para 2T. A vela uso a NGK CM6. Eu uso uma Life 2s so que uso tambem um BEC antes para manter a voltagem constante, garantindo que nao havera pico de voltagem. Abraco!

I put a new RCG-20 in a new Ultimate Biplane. The engine was running very good and I was breaking it in. On the forth flight the engine quit in the air and the plane crashed because it was too far out to glide back to the runway. I checked out the engine to see what made it quit. I found that there was no spark even though the ignition battery was OK. Then I discovered the problem. The ignition magnet had fallen out. I have had many gas engines but have never had this problem. It looks like there is some kind of adhesive in the hole where the magnet was. I checked some of my other gas engines and the magnets appear to be held in by staking. O- well, back to DLE and OS engines. The five days of repair work on the plane is not worth the cost savings of the RCG engines.

The same just happened to me but I managed to get my Hangar 9 P47 down before hitting the perimeter fence!

I was running in the engine on the ground mounted in a plane as recommended by manufacturer. On the second tank of fuel it suddenly stopped. I later discovered the ignition magnet was thrown. Fortunately the plane was not yet flown. I have sent photos to HK, but they could not be bothered to answer. It is over a month now. RCG must be using a very poor quality glue.

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 .
