Hi. Recently a fellow modeller where he purchased the locking ring and piston tank from and an approx. price with the intention of fitting them in a part started Robbe U 47 I had purchased some time ago, but have not generated enough interest to finish it.
Instead of just purchasing the bits I ended up with the complete sub. Have carried out a few minor alterations. While checking the levering unit I noticed both dive planes worked in the same direction (both up/both down). If I lowered the bow downward the rear planes went upwards which I believe is correct. Is it correct for both planes (when the Tx stick is operated).
No doubt I will have more questions shortly.
Any advice would be greatly appreciated
Regards
George
