Backcountry Supercubs Rev 2 #2 update...
Just a quick update on Jeff Lafore's new Rev 2.
Now a little over 12 hours into the forty.
We were thrilled with CHT values far below what we had hoped for, #4 is the hottest at 382F(!!!) The new BCSC/Scion Aviation/Apex Engineering team effort yielded a win we could not have hoped for. We have been consistently in high 90's in WY this week, and right out of the box solved this problem area. Unfortunately, we were not so lucky in the Oil Temp category. The NACA scoop that worked so well on the SQ 2 we used as a test bed failed pretty miserably. After several days of experimenting, we finally moved the cooler to the area in front of the #2 Cylinder and got the temps down to the 205ish, which we are happy with given the OAT. Tomorrow we will begin doing some envelope expansion and start stacking in the weight.
The Porter style gear work fantastic. They suck up descent energy like a black hole sucks up light. If you have flown a trailing link suspension, you get the idea. There is a slight bump as the shocks return to normal extension a second or so after you plop down, (the valving may need to be slowed down a touch, we will work that out with Tony during OSH). The center pivot was a big concern in R&D, but in use seems to be a non issue. I can't wait to see how the new BCSC Boss performs with this gear.
The Monster Tail shock also seems to be way too good to be true If you haven't seen the vid of the drop test from 10 feet, it was pretty cool!
Jeff opined that the tailwheel may be the most abused area on the plane in back country ops. This new system may do wonders for rear section of the air frames longevity.
299WY is on track to be at our booth at OSH, as will the Boss airframe.
Look forward to seeing you there!
