Hello,
I have just bought a new Hirobo shuttle plus and new MDS 38 engine and futaba GY240 gyro. I am gettign back into the hobby after an 8 month break. My last heli was the protech zoom/shogun electric which i could fly nose in and circit flying no problems, but this is now my first nitro heli. I do however have experience with nitro .40 size R/C planes, mainly with the MDS .40 engine. Im still waiting on radio gear.

My question is about engine break in. I have read in mostly all heli newbie guides that you can break in the engine either on a bench or in the model itself. But i cant find anywhere the proceedure for breaking in the engine in the model. Could someone detail how i go about doing this? Im also a little confussed about how to go about adjusting the main needle, is it a matter of spool up, spool down, adjust, spool up...etc?

Any help would be great!

Here is the new model:



Yes i know the paddles are the wrong way round...hehehe
