I have built both the Freedom Flight and Guru gliders.
The Guru is a moderately quick build. The freedom flight glider requires a bunch of sanding , precision measuring device and precision weighing device.
The freedom flight builds at 4.1 g with nose weight. Guru built at 5.4 with the nose weight. John will tell you how you can lower the weight which will make it a bit more fragile.
Freedom flight is reinforced with carbon fiber tape.
If you are new to building, the guru or J & H might be a better first choice.
For me, the freedom flight flies better, BUT I have not lowered the Guru weight yet.
Dave has extensive coaching and kit building experience. John has had good coaching experience. This is his first year at selling kits.
J & H is Joshua Finn, a very experienced builder that has held at least 1 AMA record. He also has a MS in aeronautics.
His basic glider is very similar to Guru. At the end of his catalog he has a glider that looks a lot like the freedom flight one.
He has construction and flight videos on line for the simple one as does Guru.
All 3 will provide a reasonable amount of help.
Flying practice is highly necessary!! The freedom flight glider will take (my estimate) 3 - 5 times longer to build very well.
A well built glider from any of the 3 ,with lots of practice, should place at most regionals.
My biased opinion thinks that the freedom flight glider has a better chance of placing at invitationals and national tournaments. With diligent construction modifications, the other 2 will also do well.
The last I looked, the Wards kit is intentionally low tech for beginners. At that time, the description was very vague, and had outright misrepresentations in it. It also costs the most.
Also, the kit would be assembled after you ordered it (I think)
Having broken several gliders, I would absolutely recommend getting either the Guru or freedom flight launcher. It will probably save many people broken gliders.
