Status: offline 		I put a Jett Q-40 (older styl) not the new long stroke on a GP Vipper. At this time I have a APC Carbin 7.4x8 on it (have not flone it yet) I was just wondering what you guys thought I should use. Not planing on racing her just put it together for some fun.

Status: offline 		The 7.4x8 is most likely too heavy of pitch to get it going.

Try the 7.4x7.5 and get the RPM up.

Status: offline 		I think Highplanes is right. It looks a little to little for a Viper. I beleave a 8x8 or 8x7 would look more at home on this bird.

Status: offline 		Then you need a different engine. A few people tried Q40 engines on Q500's around 1994-95, but they were slower than Q500 engines because of the prop.

Status: offline 		I broke in my first Nelson Q40 engine on a quickie. It went pretty well with a 8 3/4 x 6 1/2 Rev-Up cut down to 8" diameter. You might get a 7 pitch to work. But at best, it would be down from a quickie timed engine and prop combination by about 10 mph. If there is a shim under the sleeve, removing it and adding shims to the head will help slightly.
