Fyrstormer's RC Blog

back to Fyrstormer's Garage Last year I finally finished a build I started 3 years earlier, resulting in this truck: While I was proud to have gotten it to work, the truck was just too heavy for the OS 4-stroke engine I put in it -- even with a massive 6.5cc displacement, it actually produces power more comparable to a 3.0cc 2-stroke engine, which is just not enough for the big heavy Traxxas Revo. You might be inclined to say the FS-40's monster torque makes up for that, but not really -- the monster torque gets cancelled-out by the taller gearing needed for a slower-running 4-stroke engine to run the truck at an acceptable speed. So, before I managed to destroy the engine, I decided to build a new, smaller truck for it to power. Yep, another HPI Bullet. This makes my third Bullet in operation, all of which are nitro. (hmm. should I get a brushless Bullet while I still can? but I digress.) This allows a very direct comparison between the 3.0cc 2-stroke engine in my othe...

back to Fyrstormer's Garage Whew, it's been a long time since I wrote a Build Complete thread. I've barely had time to think for the past year, much less play with my toys. About a year ago, I decided I wanted to build a nitro short-course truck. But I've become spoiled and lazy Traxxas nitro RCs that have reverse gears -- and electric RCs that can reverse without even needing reverse gears -- so I wanted my nitro SCT to have a reverse gear too. That certainly narrowed-down the selection a lot. In fact, it narrowed-down the selection to...nothing. There are no nitro SCTs with reverse gears. Buuuuut, the Traxxas Slayer shares a lot of parts in common with the Traxxas Revo, so maybe I could drop a Revo transmission into a Slayer and get what I want? Well...technically yes, but of course the devil was in the details. Since the Slayer doesn't have a reverse gear, it doesn't need a shifter servo, so it uses different electronics boxes than the Revo, and ...
