Turnigy HP50 50cc Gas Engine 5.5HP

Turnigy HP50 50cc Gas Engine 5.5HP

• CDI electronic ignition with auto advance
• Walbro membrane carburetor with manual choke
• DL porting and head design
• CNC machine billet alloy crankcase
• Powerful and lightweight

Regarding this specific engine, the Turnigy HP50, could someone advise me please if it would be OK to rotate the carburettor through 180 degrees on its mounting? Physically it looks like it could be done as there are two long screws holding the carb, through the black spacer plate and on to the rear of the crankcase. I just want to be sure the motor will operate as reliably as with the carburettor positioned as shipped. If I do this it will be so much easier to connect the servos for the choke and throttle controls. in my large scale Spit. Any help much appreciated.

Hi guys I am new to gas motors, I always use electric motors, and wanted to put this motor in my boat -900MM(36") long. My question is how do you start the motor when you haven't got a propellor to crank the motor. And how do you connect the crankshaft to the flexshaft (driveshaft) of the boat. Any help is appreciated. Thanks Dolf.

Your first problem with putting this engine in a boat is how are you going to cool it, marine engines have a special water cooled head which this one doesn't. A lot of marine engines have a flywheel fitted to the crankshaft which has a groove in it to take a starting belt, this is then turned with an electric starter. It really is best to buy a proper marine engine with water cooling and possibly a recoil pull starter. Another thing is that this engine is way to big for a 36ins hull, 20/25cc would be more than enough

hello Propdinger. I have the turnigy 52cc on my 82" wingspan CAP 232 and it flies amazingly good. This engine is so strong, ease to start, never a dead stick. Start with only 2 or 3 flicks on the prop. I use 6V for the ignition and gets me about 7 or 8 times in the air, for 12, 13 minutes ever time. Always around 1/3 of power. Its just amazing and smooth. I recommend =)

I bought two HP50 50CC gas engines and am in the process of breaking them in. I am using 100 octane 40/1 mix and so far have been able to get 6500 rpm with a 22X10 Zinger prop. I hope they will improve. The engines run fine but the electronic ignition leaves a lot to be desired. One unit failed after about an hour of use and the other has a definite miss at half throttle. I hope it is the ignition. I have ordered two replacements and we will see. I am O.K. so far with them. I will probably change the rating after they are run in some more. I am not requesting replacement ignitions but getting different ones. Will keep you informed

Looks good, but I had an ignition failure anfter 5 minutes!
So I couldn't run the too long. I send back the ignition for waranty replacement and never heard of it again. So at last I ordered a new ignition

Just finished running my Turnigy 50cc for the first hour, couldn't be happier! In Dallas Tx. 90 degrees outside, Chevron 93 octane gas, Bel Ray MC 1 oil @ exactly 40 to 1, Vess 22-B prop.
A very reliable 1800 - 2000 rpm idle, a very smooth transition to 6550 rpms. This is out of the box, using the included muffler, after only a half gallon of gas!
No problems hand starting, and No Problems with the ignition...

I've got to tell you that this engine on a 15 lb Yak 55 (GP) is the most overpowered plane I have ever flown. Hobbycity could not possibly get enough of these engines fast enough for the demand

TURNIGY 50cc Gas Engine.
Ignition questions... If you will read the included owners manual, it says clearly... "If the power voltage is more than 7V, it WILL destroy the Ignition. If it is larger than 10V, it will cause explosion."
Understand that a fully charged 5 cell NiCad pack, nominally rated @ 6 volts, will rate as high as 7.5 volts! Do not make this mistake. Run a regulator @ 5.4 volts with a 2 cell LiPoly and never have to worry.
