Default Skyharbor Miss RJ, Building a pair of them.

Got a question for you speed nutts.

I have two that I am going to start on in a couple weeks, one for me and the other for a friend..
My friend has an OS 120ax for his, I'm still shopping for a motor for mine.
Here is a pic of the specs, with that said, what kind of speeds would you think? I know that thereis more to it then that, just a rough guess..
What do you think would be a smoking combo forthis plane?

I know you can't get these planes anymore, but i will do a build thread in hopes that some of you will join in with your expert opinions...

For the 120AX run a jett Muffler with a 14.5x14.5N prop at around 9,300 and will be good for about 140 level.

The AX is real close to the YS110 when its on 15-20% nitro. i am sure some have flown this plane with it.
max speed The YS1.15 on 50% or high nitro with the 14.5x14.5N prop

I know it's been a while, but did you ever build these? And is there a build thread somewhere? I have the Stiletto version, it's been sitting on the shelf half built forever now, thinking I should get back on it. Have a YS 1.40 I'm planning to throw in it, just wondering how yours flew (or anyone else's).

Aloha,
Brad
