Protek Samurai engine break-in tips


After the ‘First look’ at Protek RC’s foray into the nitro engine market back in July, interest in the Japanese (cough OS) made ‘Samurai’ engine has been pretty intense; the AMain.com-backed powerplant springing up in more and more buggys both at home and further afield.

Quick as ever to offer support, AMain.com’s Marty Korn has helpfully posted a detailed and very helpful break in guide for the engine which we think any novices or beginners or even more experienced hands might find useful!

OS Speed B2101 engine announced


OS continue to advance and innovate, announcing their latest powerplant – the OS Speed B2101 which features a square bore & stroke, the engine itself has a slightly smaller displacement than normal (3.46cc compared with the standard 3.49cc) however, OS’s frontman Junichi Shimazaki said that the engine was found to be much more controllable, a reduction of wheelspin in the bottom-mid range of the engine.

OS have said that they will continue producing the hugely popular Speed 21XZ-B Spec II, the engine of choice for countless racers round the world, not least Atsushi Hara who takes to the track this weekend at the Italian Job Race in Italy, preparing for the Worlds next week. Expect the B2101 to be available in October, sold alone or as a combo with the OS T-2060SC tuned pipe.

After selling out of all their various versions of BLAST engines, RB have been quick to act introducing a Limited Edition engine named ‘The ROCKET’. Made in Europe to the highest specs and ready to blast off (see what we did there?!) the .21 Offroad engine is a long stroke 7 port with 14.55mm turbo, lightened balanced crankshaft, lightweight piston and competition conrod and turbo combustion chamber.

Orion CRF RS Review: On the track


After an unpredictable European spring and summer finding the perfect conditions to test an engine has been anything but easy. With much assistance from the iPhone’s weather app we found a perfect day, borrowed an Inferno MP9, and headed to the track. Twenty six degrees celsius and a clear sky: perfect conditions; a cooler temperature would be too kind to our engine, whilst everything above the 24-25° means a fair challenge for any powerplant.

“It’s a powerful mill with Championship-winning pedigree that instantly reacts to skillful inputs.”

After installing the Orion CRF RS ABI engine in the car (thanks to TeamOrionShop.com), we started with the break-in by performing a ‘Japanese style’ procedure for the first 5 tanks with our Runner Time fuel.

First Look Exclusive By Stephen Bess:

Known as military nobility in Japan’s rich history, samurai were renowned for their fighting skills and their eponymous battle swords that are now displayed over the mantle of every aging hipster in America. ProTek RC, a division of A-Main Hobbies, sent word to the industry just last week that they had a Samurai of their own in the form of a .21 nitro engine. Set for release in mid-August, this engine’s release has already caused quite a stir on social media. I received a test sample and decided to crack it open to check out what makes this Samurai tick.
