This is a fantastic engine that responds extremely well to my modifcations.... has excelent stability, killer bottom end and will idle for weeks...the modifications give an overall increase in power as well as increasing the useable RPM range...

I finally got to run the TNS K5 a few times and its stellar. The power-band is very smooth but strong at the same time. There is tons of bottom and mid range usable power. The top end also has very good usable rpm although it could use a little more so managing exhaust set up will come in to play here. But all in all a fantastic mill that puts all the power down to the ground so efficiently. You will be extremely hard pressed to find a better performing .21 off road racing engine period. Its very light too only 349g; lighter than most engines out there.

Neal provides excellent customer service and communication. He's a busy man but still finds time to answer our questions and provides suggestions and support. This Modified Royal came to me in excellent condition. The internals look spotless and factory clean after the break in. He uses high quality fuel (Bones break in I would imagine). His mods look fantastic and pristine You could tell great care is always taken. The best part was how fast shipping was from Canada to my door in the U.S.
in under 2 days!!!
ill report an update once I've run this BEAST I'm sure its going to rip real hard and idle for days.
