Built me a removable upper deck today for my camper shell. Nothing heavy duty but more than sturdy enough to haul a couple extra planes to the field.
Put together a Multiplex FunJet Ultra last night that I've had hanging around forever. HS-70MG's in the wings, still trying to think up a good power system for 3-4S...

Try a 1000KV in-runner on 3S with a 5x4.5 APC. Ballistic! for 3S. Use a 50amp ESC
1000kv is a bit too low on the rpm, that would swing a much larger prop very easily. We suggest a 2900kv 35mm outrunner with an APC 6.5x5.5 prop on 3s, I have a 2600kv outrunner I need to swap shafts to get to work but I think it should fly it well.
I had a 35mm 1000kv 5x4.5??? on 3S 2000mah on one and it zipped pretty good 110+-mph. You must be looking to break 160mph and out run the radio signal. And now that I think of it you are absolutely right about a bigger prop. I think it was a 6x5 not a 5x4.5 but I did have a 5x4.5 on something??? Dag gone it just can't remember.... may be the other popular speed wing. Messed around with them for a season or two . Loads of fun.
I think you need a cheeseburger to get your brain trackin straight again
35mm 1000kv outrunner is what's in my 48" Slick, swingin' a 13x6.5 on 3S 2200's.

The stock powerpack for the FJU runs a 35mm 2900kv outrunner on 3s, and swings a 6x5.5 prop.

1000kv at fully charged 3S 12.6 volts is 12600 RPM. At 4.5" of pitch that's about 54 miles an hour. Now @ 2500KV, now your talk'n.I had a 35mm 1000kv 5x4.5??? on 3S 2000mah on one and it zipped pretty good 110+-mph. You must be looking to break 160mph and out run the radio signal.

Kelly, the cholesterol from all those cheeseburgers is cutting off the blood flow to you noggin. Ask me how I know this....... but since I paint and eat cheeseburgers I probably wont remember.
