I have2 OBR 34 reeds, both with less than 1 hour run time yet, I was starting to think reed engines are not capable of high rpm. Umm, this OBR is running the same rpm as a full race 27cc engine! Listen to the pitch (note or frequency) to tell rpm. No matter the size of engine, IF it's a 2 stroke single cylinder the pitch will be the rpm. And yes that's exactly the sound difference between a cheap nitro basher 25-28k rpm? and a race 1/8 scale 40,000+ rpm! One whines along, the other one shrieks! Check it out if you've never seen a 1/8 scale race. Now to get my OBR's running like this one!
BEWARE OF WALLKE!!! I paid $2,499 for my H6 a year ago. I questioned the mileage being short of what they claim so they had me do dangerous tests that burned up my rear hub and controller. Now they have no replacements for the controller. I paid for a new rear hub, $400 and a new controller, $130 and the controller they sent doesn't work. They sent me another one but it was a used one that also doesn't work. Now they have no more to send out and the $3,029 that I've now spent on this bike is a total waste!!
low end is very poor, guessing it needs tuning, if not...im not impressed with that engine!? I just bought an ESP race ported 32, its an animal compared to this :o ?
