Earmarked in China as the DL50-Killer. The Turnigy HP-50 has shamelessly borrowed porting and head design from the DL and combined it with a CNC machined billet alloy crankcase to produce a powerful, lightweight and reliable engine.

Never power the CDI with more than 6v. Doing so will break the CDI module. Take note of your battery packs true voltage when fully charged.
I put this engine in my 83" Spitfire with home made exhaust which exits as per full size on both sides. I added smoke system for realistic start ups. I have just flown it and the power was awesome big loops from level flight.Not very pleased with this engine. The first problem, the engine had no compression,
put some oil in spark plug hole, compression came up but would not stay, after a half hour
compression was gone again. After changing piston ring, compression was ok. The second problem, engine was not getting fuel. dismantled and cleaned carb. The engine would now start and run for a couple minutes. The third major problem, I noticed a bind when turning the engine by hand. The roller bearing on the piston rod lower end came apart. I am currently waiting for my order of bearings to arrive So far this engine has not been mounted on a planeRecently I bought this engine from the DE warehouse. After 3 days it arrived in Belgium. The HP 50 Turnigy started up after a few flics the first time. The muffler delivered with the motor was very noisy. The second time the engine started also right up until I heard a noise and the
motor stopped. When I moved the piston to the top point I heard there was somthing between the piston and the cilinderhead. Something was broken inside the engine. I sent back the motor to the waranty department in Hamburg given by the HK support. After 8 days I received the bonus points on my account. Despite the misery HK acted correctly. Unfortunately transport cost is lost. Now the engine is in backorder. Hope this becomes no neverendign storyI ordered it for my friend. He will put it in Miss Morava from topmodelcz. Engine is well made, come with 2 glow plugs and all hardware that is needed to mount it on firewall. For this price- unbeatable!Got this engine and fitted to a Seagull Nemesis with the intention of racing it in F1 class. Fitted 18x12 prop for firsts runs.. only needed some minor tweaking on High needle to get nice tune.. Seems ok so far, but have fitted 18x14 prop to try. Also need to tacho the prop to check RPM's for racing... Great value though! Cooling fins had minor damage on my unit, but not enough to worry about.I have had this engine since May 09. Engine lost compression drasticly after 100 or so runs and flights. The piston and cylinder were fine. I ordered a piston ring for a Husqvarna 335 XPT (California version) for $12.00 and now she has compression.
If you crash... you will destroy the timing disc at the rear behind the carb. $6.00.
I damaged the CDI ignition in an accident and replaced it with an RCEXL.
She is a cheap engine but at least the parts are available and you can fix it yourself. 5 thums.Das war der schlechteste Motor den ich in 40 Jahren Modellbau hatte.
Schlecht verarbeitet. Zwischen Kopf und Kurbelgehuse teilweise 2mm Spalt. Ich hab ihn in den Mll geworfen und einen DLE gekauft. S u p e r.Un super moteur pour un prix tout a fait raisonnable , j'en suis tres content , je vous le recommandeVery nice Motor
with 22x8 Wood Prop 7100u/min
and 23x12 CFK Sport Prop 6500u/min
www.modellstaender.deVery powerful motor, equal to DLE55 but after 5 flights and due to a noseover the crankshaft moved back and damaged the rotary valve
and rear crankcase half. Hobby King say as it is not listed on their
website it is not available. My engine is now scrap. Beware , when buying a gas engine First check that ALL parts are listed, if not forget it. Hobby King all you have to do is put in a special order to the
manufacturer for the parts I require and i will continue business with you.
