When we discontinued the 4.5 HV Pro motors, we took back a lot of them from distributors---we are goods guys.
So, we had all of these 4.5s in our motor mfg department collecting dust. Then Jay Halsey and Bob started looking for some system for the Ofna SC and decided on the Havoc Pro/ HV 4.5 Pro motor. They seem to be doing well with this combo.
This is why we are combo-ing this up for sale. We OEM these 2S Combos to NitroHouse. Many of the other SC vehicles do not seem to have room for this longer 550 motor, so this may be a limited market, but this set-up seems to be winning races.
We can always reactivate the store listing if we see a demand.
