Glow helis: ratio 8.21 original with modul 0.7 is piniomn 20 and 164T main axis distance 65
and my set is ratio 8.21 modul  1.0 is pinion 14T main is 115T axis distance 65 - so you dont need mowe bearing house on glow!
Gasser helis ratio 6,07 at originall gasserman conversions modul 0,7 pinion T27 main T164 axis distance 67.0
and my new set  tartio 6,07 at originall gasserman conversions but modul 1 pinion T 19 main gear 115T (same as glow) distance 67.0 mm!
Conclusion: Glow and at Gassers you don't need to change anything, just swop the gearing set and go fly!

IMPORTANT! How to align the gear mesh.

lose 6  bolts on each side frame  that go into the clutch and main shaft bearing blocks 
then cut a strip of regular paper and thread it through the pinion/main gear until it sticks out both sides.
then loctite and tighten all the bearing block bolts and remove the paper. The gear mesh will be right
Dont forget to go fly :D 



The difference??
