I know many 1/6 & 1/8 guys who would be interested. I personaly think its a little to much smoke. My main concern would be how much smoke oil does it hold, and how hard it is to fill. Its a major pain to get inside my 1/6th stuff. Then would be operating volts. My Stuarts are 12v and the T1 is 24v. I suppose I could run a seperate battery & switch it on/off from the transmitter. It would be cool for just the start up puff of smoke. Then shut it down. I could also use one for a "destroyed" Stuart I have.
I know you are targeting Hl but considering all the other scales/brands would mean more sales. If it was in the $20-$25 range I would probably do a few. Nice work though.
