Hi

I had both versions of the Beryll (sold one recently and still flying new version) and would suggest a word of caution on equipment selection as you might find the plane over the weight limited very quikly. I have seen claims of the plane coming out with an all up weight of 4 600, but find this hard to believe. Both my planes at 4920, the older version (sold) with the foam wings initially being lighter than the new version with composite wings. You can save a lot of weight on prop selection (up to 50 grams depending on size), spinner, batteries and switch selections.

I use the following

TP 5000 (heavier pack and you can lose about 100 grams using TP 5300 or new 10 cell pack at 1090 grams)
Futaba servos (9154 and 9650)
Carbon spinner (Genesis version, fits perfect and very light)
TP receiver battery
Digi switch

I suggest the following re-inforcements.

Laminitate the stab leading edge with some clear tape as any stone chip makes quite a mess of the leading edge.
Laminate the bottom of the landing gear plate with some carbon, the ply is very soft and compresses easly leading to the gear having to be tightened regularly and ultimately breaking.
Re inforce the battery plate, after two years the nomex takes a bit of a beating.

Regards
Burt
