Beautiful glider. The turn is so tight and precise.

[@TheScreamingFrog916]

It's been a while since I have flown a sailplane. This brought back great memories. Love your enthusiasm. Thank for making this review, and happy landings.

Its really nice to have reviews from other competion pilots instead of casual flyers. dont get me wrong, there is nothing wrong with hobby flying these things but i am an F3K pilot myself and its nice to hear kinda of what competion pilots want to hear

[@rcgvideos]

Thanks man! Came in 2nd place at the Knoxville F5J contest with this one. Another pilot had one and placed 4th or 5th. I'm still loving it!

Wow, just Wow. I haven't flown comp since about 78-79 when I got a 2nd place at the LSF nats in Australia. Life changed and the tech and expense went ridiculously nuts after that. I was deep into scratch building my own designs for about $100 and continued to fly recreationally. Got to the point that most days I could put a thermal ship up and only bring it down when I wanted or when my neck got sore. In those days I was building gliders to about the same wing loading (5 oz/ft^2) and A/R round 13 or so. An A/R optimization program I wrote based on Martin Simmons book suggested the best duration in dead air could be obtained from an A/R around 10 or so depending on section L/D characteristics, but this was a slow floater, only practical in almost zero wind. Higher A/R increased wing loading and speed. A flatter glide yes but lost height faster due to increased speed at higher wing loading. Still this was advantageous because you need to get upwind to pickup a thermal, follow it downwind while gaining height to then hunt upwind to the next thermal. So minimum sink isn't everything. The program also suggested that in theory, glide ratio just keeps improving the higher you go with A/R, to a ridiculously impractical extent. So basically I just ended up with the conclusion that the AR and wing load determine the wind speed and thermal density that the design is optimal for. In other words, the optimal design depends on the conditions on the day of comp. You can't predict that for any one comp day, so there remained an unresolved question as to optimum A/R. So that's an outline of my journey in RC sailplane. From those days to seeing the specs on this glider with almost 20:1 AR combined with a wing loading just under 5 oz/ft^2 is to me just absolutely startling and amazing, as is the price tag by the way. It's a big span to turn on a dime like that without stalling in inboard tip, quite an achievement. I did have models that could do it but employed boundary layer transition control to retain attached flow at low speed and high CL. This ship doesn't appear to have such devices. I assume that is testament to the accuracy of mold manufacture these days. It;s a good ship, I'm much impressed!

Wow Ken! That's awesome man. We need more builders like you!!

[@bobbysandoval3660]

OK now I’m really excited just picked one up! Now I’m very happy to hear that it flies like an F3K and now I can’t wait to get it in the air!! thanks awesome review!

Good choice! You'll love it!

[@oznerriznick2474]

Beautiful aircraft. Solar cell arrays on the wings would seem intuitive.

[@xnoreq]

No way, that would make it way too heavy, increase wing load ... essentially destroy the performance.

[@oznerriznick2474]

@@xnoreq I was thinking more in the way of incorporating ultra thin solar arrays as part of the wing structure and not changing any the weight or aerodynamic specs. There are super light efficient materials out there that could be used. Just an idea.

The Radian is great for sure, but not suitable for high level F5J competition. Just a different class of glider all together.

Yeah, the younger generation mostly. I am seeing more interest in gliders lately though. One new glider pilot in my area recently and another got his first F5J plane.

[@RCjunkie]

Let me know when you want to sell it?

[@rcgvideos]

Ha! I'm planning to fly it for as long as possible.

[@RCjunkie]

Just keep me in mind when you do want to sell this plane. Or knows some that does.

[@miker1473]

$1900, and you STILL need to buy more parts to complete? Yeah....no thanks.

[@rcgvideos]

Yeah, it's not cheap, but this is the way with hobbies. If you want a really nice set of golf clubs, or a mountain bike, or just about anything as a serious hobby, it's going to cost a lot. It has to be what you want to do and then it's well worth it. Most of the competition guys have 3 or more planes at these prices. I'm having to make due with the one plane.
