RE: Twisting APC props

I hate to burst your bubble Jr., but we have NEVER made or sold a TT Pro .40 piston/cylinder assembly. HN made some for the TT 36 for control line stunt, but that's a different animal.

Where...

OS Hanno and 61 RF/SF piston/cylinders

RE: NEW NELSON Q-40

RE: NEW NELSON Q-40

Barry, I'm not sure what the sweet spot is, but I'm sure we will see it this weekend. I would run the biggest prop the engine is happy with and go from there. If I can run an 8 pitch prop at PHX, I...

RE: NEW NELSON Q-40

RE: NEW NELSON Q-40

Not an ignorant question, Stan, but these new engines are not the same configuration as the engines run in F3D. They are side exhaust, not rear, and don't run with full wave pipes like F3D. Henry...

Don't you guys know that the course has been shortened? We now fly with the honor(?) system. If you say you didn't cut then that's good enough for us!

RE: NEW NELSON Q-40

No declaration necessary for new engines or modification to existing engines (and there have been many over the last twelve years, some increased power, some for longevity). If this were the case,...

RE: NEW NELSON Q-40

RE: NEW NELSON Q-40

I started shipping the new engine on Monday of this week. Henry Nelson and I have been fooling with this thing for over a year now and it's time to unleash it on Q40. I really didn't expect to have...

RE: Ballistic Pattern ABC Engine Liners

Once again, we are not making these for FSR's. Only for RF, SF, and Hanno Special. At present we are porting the liners.

Most of the parts have been sold. If you want to be on the list for...
