With the Valach VM 85B2-FS the legendary Valach "voice" and smooth running characteristics are now available also for your smaller sized models. The VM 85B2-FS is the perfect engine for our Sopwith Pup, our 33% scale Pitts Special S1-S, the 33% scale Piper L4 Grasshopper and the quarter scale Bücker Jungmeister from Paolo Severin. The VM 85B2-FS sounds just like the famous VM 120B2-4T, pleasing but powerful, and at a warm low frequency.
Due to being a four stroke boxer twin, the low vibration is nothing but sensational, and torque is really high. The response to the throttle being opened is so smooth without the slightest attempt to surge, making the Valach VM 85B2-FS absolutely ideal not only for scale models but also for aerobatic models and glider towing.
The VM 85B2-FS is also available with a starter. With the current version of the VM 85B2-FS the starter can be retrofitted anytime.
