Hey I remember them Graupner Speed 400 engine stickers!! I had every winding type they sold in the 400 size cans and flew them with various battery types up to Nimh then went to brushless CD Rom motors and lipoly cells..never looked back. I like the scheme on the blue plane Im sure it showed up well in the sky.
Nice clean job on the SIG Wonder. Those Coroplast planes sure would be tough on the rods bushing being typically more heavy then there wood counter parts but great for fast builds and fuel prof and ready to rock
Well I have / had hopes for the AP .09 as its showing good performance with the
APC 4.75 x 5.5E / 22.24 static / 116 mph My only worry is unlike the AP 15 it doesn't have a bronze bushing and you just said your's went sloppy at 25k. I will be all over that number with aluminum on steel. Looks like I will have to use generous amounts of oil to pull off using it for speed. I will have my fuel guy blend up some 20% nitro with 10% castor and 14% synthetic. Perhaps I can prop up to slow things down a hair.
Cut 5.25 to 4.8 x 6.25 / 20.5k / 121 mph static. / 23.8k unloaded / 141 mph on a light small clean craft.
