Right Ive had this engine since August 2014. It was my first nitro engine in a trex 600n dfc. been running on 30pcnt and then 25pcnt nitro.I ran it with the rjx os powerboost copy for a year until I wrecked the pipe, now I run withh an outrage 56. Its really powerful and starts first time every time. It sounds like the rear bearing has gone on every flight though...lol. My friend whose used to OS engines thought so anyways.. Seems to be pretty resilient as well as a noob with nitro i must have run it lean from time to time. Today I managed a 15min flight on one tank..i'm amazed. I have an os 55hz and a ys56sr to test it against..I Received the engine appearance is very good Carburetor design is very good i just Run in the engine using 12pcnt Nitro 18pcnt Castor Synthetic Blend High speed needle open counter clockwise 2 turns,Low speed needle factory adjustment.the engine runs very smooth and idles perfect Recommended to all Nitro and gasser pilot's.This engine have a lot of torque>>>Thank you Hobbyking Fast Shipping as expected......
This engine fit's on my Raptor,Sceadu,Aeolus..I'm using my own design pipe to meet my Demand..No problem using stock pipe's
Engine looks fairly good on the outside, and pretty good on the inside (only piston looked a bit less perfect).
Fitted Ignition to it. Found spark plug need 3 rings, otherwise it protrudes into the combuston chamber.
I run it on gasoline (like the GO Engine GH56) fuel/oil mix 10:1
Engine started right up, and seems to run good on this.
Still busy breaking in, will revert later after flight test, but looks promising so far.Purchased this engine and was very impressed with the workmanship.Mounted it on my .40 size plane and it is a blur .Tested it on my dyno for the best prop and got the most thrust with an 11/6 .Starts very easy and idles down perfectly . What more could you ask for . Will but another one .When I got the engine I compaired it to the Go Engine I have. It is the same engine without the CDI. All the flying has been in my TT Titan 50SE. First ran it on glow fuel to get an idea how it would compair to the OS 55. It runs as well as the OS, at a fraction of the cost.
Next I installed a CDI and ran it on Methenal and oil. Running it with the CDI increased the run time about 15 percent compaired to glow fuel, and the power loss was very small. For the type of flying I do Sport flying, it does everything I need and well.
Next I ran it on gas and oil still using the CDI. It runs very good on gas. Again with enough power to do my style of flying.
I Love this engine and hope HobbyKing keeps it around for a long time. It is a very good engine that is affordable. I think for the money you can not do better.Recieved today,1st impression -outer appearence not like thunder tiger or os 55,from muffeler exit i saw scratches on piston upper edge,it is indeed ringed.after putting glow plug piston pressure is good.engine when turned by hand is smooth.will test after 2 weeks to see performance.
