Pain in the rear to start and break in-But after that LOOK OUT!

Impossible to start to break in. I couldn't get more then a sputter from time to time. It was about 60 degrees outside when I was trying to start mine for the first time in my 4.6 X Savage. Finally after wearing out my arm I put a Roto Start System on it and swapped it for a medium glow plug..a OS #8 and after cranking with my HPI Roto Starter got it started. It ran horrible but it ran and I went through the tedious break in for 8 tanks of fuel. By tank 4 it was running and starting better but still a pain to keep going at times. Be Patient. By tank 9 I leaned out the high needle one turn in and the low speed needle one turn and cannot keep the wheels on the ground! This engine is a Beast! It starts very easy now and simply has more power then I know what to do with! It is a ripping Beast. So be patient. I suggest you warm your cylinder head with a hair drier for first time starting if it is cooler outside until this engine gets broken in or highly recommend a Roto Start for it. In the end you will be more then pleased with it! it is one of the best engines I have bought. And I am a OS man. Very happy with this powerhouse of a engine! Also FOLLOW the Instructions! Use 25% fuel! I could not get mine to run well on 20%..it really wants what the Manufacturer suggest...25%. This Engine does not care how heavy your Savage is...It will make it ground pound like it was meant to do! Read full review...

4 1/2 HP for your R/C, more than enough!

This has to be the biggest and most beefy engine I’ve seen in R/C, anything larger I’d assume came out of a Ferrari. Unfortunately I never got to install it. It wouldn’t fit the application I’d bought it for, however the build and smoothness of all the moving parts showed that extreme attention had been paid in building this monster. If you can fit it, but it, and buy the best wheelie bar you can find!Read full review...

Great HP with lots of torque

I have owned a lot of the older model LRP Spec2 engines and the Spec 4 is even more powerful. Will be using more of these engines in my new builds.

Powerful

This engine comes ready to go. Do not touch the screws to tune it. It's a very strong engine. I put on a 1/8 truggy and it will fly. Holds the tune great.
