Phoenix Model Piper J3 Cub
#5
I commissioned a CMP Cub this spring around the same size ( 91") and have fallen in love with it. Weight is 11.5 lbs, powered by a Saito 125 converted to gas and it flies great and sounds fantastic.
One quirk is that it sometimes has a mind of its own on takeoffs and I'm working at resolving that after finding that it needs an ounce of tail weight to dial the CG to the sweet spot that makes Cubs such a delight to land. I will trade the supplied tail wheel + one ounce of tail weight for an Ohio Specialties that will buffer the tail wheel and set it back a couple of inches. That may help with takeoff handling.

I compared the 84" manual with my 90" manual.....many of the same pictures, drawings, wordings, etc. Major differences are the flaps (or in your case, the lack of them). I think I've now burned almost a gallon of fuel on this bird and have a blast flying it....did you know this bird can do a KNIFE EDGE! And now that I've moved the CG back a bit, spins are getting tighter and tighter. We had a good cross wind the other day and I shot a couple of tanks worth doing some slide slipping and landings.....lot of fun!

Thanks and yes I'm buying the 90in which has flaps. I'm into scale and of course J-3's don't have flaps but that's ok. I love doing slips and Touch and Go's so it should be fun.

Just starting assembly of my kit (the version with flaps and the 90.5 inch wingspan). Wondering which size 4-stroke is a good choice ? First impression is that a 1.20 4-stroke might be a bit small/underpowered for it ??? Am now leaning toward the OS 1.55 4-stroke ??
Thanks. Bob
