STS is based in Taiwan.
They have 2 variant of the .12 and a new 5 port variant coming out soon.
The 2 available now is one being standard turbo engine and the other being hand modified.
The hand modified one are listed at 1.35HP. From what I have seen, the engine does have 1.35HP but it tends to have it in the high end. Low end torque is a bit less than the NovaRossi but on a big track the STS can blow away the NovaRossi.
The engine is relatively inexpensive because it is still new to the North American market.
My friend is selling the hand modified for $250CDN. I would assume the engine to be around $150-$175US I guess.
I am waiting for the 5 port version. It is estimated to have around 1.5HP.
And yes Team CRC is the North American distributor for these engines. If you check out the STS RC
site, it indicate Team CRC distribute the engine. Team CRC may have a different branding but it is the same engine.
