I'll be getting my trophy 3.5 on Tuesday ( Hopefully as i ordered on Saturday ) and i will be running the engine in as soon as i get it.
Hopefully it'll be good enough by afternoon for some bashing, If its cold just keep a hair-dryer handy, mrs wont be happy, but it saves many hours of blisters and scuffed knuckles!

.all idone on my vid here,take it easy ,break it in with time,...

yeah all the "use a lower percentage fuel to break in", is all a load of overblown nonsence...
Just break in your engine with what fuel your going to be running it on, and dont change....

Before starting the engine, id very much recommend preheating the engine to ateast 210 - 220F before starting. to give pre-expansion of the sleve and piston so that pinch and friction is less, giving better life of the engine...
Complete each tank accordingly, shutting the engine off and placing the piston at BDC (bottom dead center) (PIston at the very bottom), during cool down... This allows the sleve to contract fully when cooling, instead of the piston stopping the sleve contracting against it....

Follow simple steps like that, and your engine will give you great performance, and great life span....

I run in my hpi trophy 3.5 today using the "new" method first 2 tanks gentle between idle and 1/4 throttle then next 2 tanks going up to 1/2 throttle then another 2 tanks going up to full throttle seems a good break in to me kept checking temps all seems good but we'll see how it goes in a few months time

i'm new to all this, rc and nitro. iwas wondering if it would be a benifit to put a drop or two of after run oil in between tanks whilst running in to aid lubrication while it is in the coooling process before next refill.

[greenfingers]

started to break in my engine today.... 1/4 throttle 1st tank then 1/4 throttle with short blips of half throttle for next 2 tanks. then the steering went, apon inspection i found 8/10 teeth stripped inside the steering servo. now i have to wait couple of days for new metal geared servo to arrive.   tut tut ansmann really nice car (virus 2.0) but not happy with poor quality servo on what id call a important function. (almost crashed into a wall with loss of steering.
p.s.  left out the after run oil between tanks.
