I was surprised as well, I suppose it was because I didn't need to get formers right on or anything, just however I wanted them to be!

I think it looks pretty good!

Cool! My Carbon fiber spar is due tomorrow so hopefully I can get your Radjet design built soon here!

Sweet, next time I fly, it'll be a Funjet, a Radjet, and a Foamboard Radjet.🤣🤣 I'll probably throw in a 3d plane as well.

I hope the Foam board one goes the fastest! I am trying to break the foam board record right now...Do you have a video link of the record?

Yup, here it is:

If you are trying to break the speed record, suggest you change over to:
1) digital servos, not analog. Better control of surfaces, it will reduce your chances of flutter.
2) Are you totally sealing the air joints between movable surfaces.
3) Should look at the possibility of using V-tail. Drag is reduced and adds velocity when you reduce the frontal area from 3 to 2 segments. That's why Q-500 increased the racing speeds when they went from 3 to 2 surfaces tails.
4) Buy a top notch battery (need to do research to find a dealer you can trust) like there are 3 grades of lithium, etc.. You need the correct motor/prop to run top efficiency of both in flight. It will unload in flight and increase your top speed.
To get from from 195mph to about 200, we hade to cut and sand (reshape with prop gauge) the wooden props and test fly each one(we had three planes) and you would vary which one to use depending on how good the opponents were. You might even look into motor timing if you understand it. In the end, it's the props that determine it.

Yeah, I’ll probably try to design a V-tail sometime, problem is wing mounting (I really don’t have many resources). And as far as digital servos and batteries…. I really don’t have much money either 🤣. But I do have some really nice motors lying around, as well as (some) nice apc props. Probably going to invest in some 7x15, 7x12, 5x11 props soon.

Yeah, I am running 17g digital servo and they work really well..Though they have gone up in price since when I bought mine! (These are the ones I am running..They were $28 when i bought them! https://www.amazon.com/dp/B0DDPM1KB8/?tag=lstir-20 )
As for battery I am running a CNHL battery which are supposed to be better.
