BGD Base 2

BGD Base 2 M

After the Cure 2 EN-C here is the new Base 2 from BGD. The new generation BGD gliders seems to be developed with very good software, a new designer ‘Tom Lolies’ and it seems that they are quite different from the past creations.

My friend lends me his new glider, and I flew it from 92 to 96 all up.  Launching the Base 2 in nil wind requires a steady pull. It slows a bit at 45 degrees, and a little more pull to get overhead. The inflation in more than 5 km/h is easy and the take-off is immediate. 

I flew the Base 2 on several occasions, and once with the company of two Rook 3 MS at the same load for all 3 gliders! 94,95 all up. 

The brake pressure is on the moderate side. A bit longer than the Rook 3 or the Rush 5  but reactive and linear.  The turning behavior is quite good, with good agility for a high B while having a very calm character.  I could turn the Base 2 inside any thermal while lowering slightly further the brakes in order to get a tight radius. Overall, I can say it has a very balanced turning ability, with no diving in turns and relatively a flat turn.  At 95 all up, I could apply only 15 cm of the brake, and guide the Base 2 in an efficient flat turn, in weak conditions. 

In weak thermals, it seems that the Base 2 has a very good float ability, that enables it to climb really well in the weak stuff even loaded at max weight!   Facing a mellow valley breeze the pitch movements are absent and the Base 2 rises effortlessly and moves forward in the airmass. In stronger conditions, the Base 2 pitch back a little but still climbs very well when I flew it at 92 all up.  That’s is why I felt that the Base2 needs to be loaded at the top all the time for good efficiency in the air, and while loading it, it still delivers one of the best climb rates in the high B category.  The glider feels big, and very calm, even near the top and that’s why loading it at max felt much better.  

Talking a bit about the pleasure in flight, I can say that the Base 2 handling and brake authority allows a newcomer to the high B category to understand and cope better under that machine while having fun. As for expert pilots who desire a direct feel and more dynamics on a high B, they will still feel the reactive brakes but probably will miss a shorter and sharper feel. But I think 90 % of high B pilots would be very happy with the handling and turning behavior. 

The Base 2 comfort in roll and pitch is very high! I sensed that I’m flying a low B glider in that matter. The Base 2 despite the 5.7 AR, absorbs very well the turbulence and the overall movements in active air are present, informative, very dampened, and very calm. The Base 2 delivers a smooth ride all along in XC condition.  The Rook 3 has more pronounced feedback in overall conditions.  It resembles the Rush 5 in calm behavior. 

The trim speed with the same loading as the two Rook 3 beside me is slightly higher on the Base2. The gliding in moving air done more than 4 times and 5 km glide while the Rooks pushed slightly on the bar to match my trim speed, showed me exactly the same glide as my reference in the high B category. The full-speed glide of the Base 2 which seems to have a shorter distance between pulleys, has the same top speed as the Rooks. The glide at full speed showed me also very close gliding results after 5 km the rooks arrived 5m higher…So practically the same and insignificant. 

While at bar, it seems that the C steering is quite smooth, efficient, and easy to use, and I was able to control the glider quite well with total tranquility in most conditions. 

Big ears are easy to hold, stable, efficient, with around -3m/s with bar. The releasing of the ears will enable the Base 2 to reopen by itself in a gradual and smooth way. 

Conclusion: With the new Base 2, the BGD team has succeeded to raise the level of their products as they did on the Cure 2. BGD managed to produce a very comfortable high B, with good handling and top-end overall performance in both climb and glide. I believe that those new high B’s can get their owners to new dimensions and long XC flights while being easy and relaxing to fly. That combination of performance and accessibility is the strong point of the Base 2, and I think it will be quite interesting and rewarding for pilots to test fly it.  But please remember to load it at the top or even at 96 to feel the efficiency in overall conditions. 

BGD Base S at 85 all up

A few words flying the Base 2 S at 85 all up with the new Genie light 3. 

My friend just got him, but as he was busy today, I had the privilege to test fly it! :-) 

The Base S rises easily without any hardpoint. Take-off is immediate. 

I flew in some difficult stable conditions below the inversion, and then I got some two good thermals that pierced the inversion. I will mainly comment on the handling of the S size. The brake travel is moderate, not too short nor too long. A bit longer than the 777 R-Light S. A Bit less than the Swift 5 S, and more firm. 

The pressure on the brakes is firm and not moderately light like the Swift, but very linear and precise. The Base 2 S is more dynamic to fly than the M size which is logical. That little more dynamic feel is what I really wanted from the Base 2 M!  Incredibly perfect feedback and agility! The feedback comes from the risers, not the brakes, in a polite way that enables the high B pilot to follow the movements. 

Getting the super narrow thermals was super-pleasurable, as I could place the Base S exactly where I wanted. The pitch movement of the leading edge is super neutral, with the feeling that the Base 2 S is going through that airmass quite efficiently!  I like that trim speed, quite fast for a high B! The accurate feedback and the glider response in the airmass feel like a higher-rated glider!   In all those tricky, and turbulent conditions I never had any tip collapse. I think flying the Base 2 M or S at max load is the way to go. I didn’t feel any problem in weak thermals, and I felt that I’m gliding quite efficiently at that load.
