Your comment is often to the point which I think so.
I set the batteries as indicated in the manual,but I feel it necessary to put some kind of tiny weight
in the bow side to refrain a slight nose-up when especially at faster speed.
Frankly speaking, I have been aware of this point.... And you also have noticed this phenomenon,,,??
I'll try that in coming April when my local lake will be re-open to the public.
A picture of the kit box seems nearly the same as my boat sailing pose.....??
Still pose and/or bow-stern balance are also like a real one....
This may be from a powerful brushless motor of 2050KV by which her nose is apt to rise....?
Or from a design characteristic as I built this boat fundamentally and faithfully based on the manual...
Everything will be made clear if this phenomenon? may be improved or hull characteristic in April test...
Other U-tube videos may also be of some reference if this phenomenon could be observed...
