3 Sep 07 - Changed the propeller to a Ramoser VarioPROP 3-blade hub fitted with 7" x 4.5" folder blades with a little additional pitch. In flight the model was obviously more powerful and a good improvement but only got a short range before I lost radio control of the model. Fortunately it landed flat and no damage was incurred. Completed a range check and only got about 5m before problems occurred. I'm going to have to check the RC system.
24 Jun 06 - Flew for the 1st time today and was a little underpowered. I'm going to play around with propeller options to improve things.
5 Jan 06 - It is a boat or is it a plane, well it's both - you can operate on water or land, it really doesn't matter. The model has just been finished and awaits test flying.
