schnuepp2 no, there is no phone holder included. However you might fine some phone calmping-device that can be fixed to the handlebar on top of the TX.

schnuepp2 I do not know your boat, but the dimensions of this battery are 45 x 96 x 20 mm (not including the cables). The weight is 166 g

schnuepp2 Yes, this cell meter can handle LIPOs from 1S to 8S (one to eight cells).

schnuepp2 24,5 mm width x 28 mm length x 17 mm height

schnuepp2 I had also seen both versions in presentations on the Internet. I had bought the kit with the included motor and decided on the internal mount of the motor. This solution looks much better and provides a better protection for the motor. The motor cooling is still sufficient with the internal installation. With this glider you will not run the motor at full speed all the time. Besides, the mounting in front of the fuselage would have required a disassembly of the motor rotor an stator, since with the motor provided in this kit, the motor shaft was fixed to the stator. With the internal mounting the motor housing (stator with the magnets) rotates inside the fuselage, whilst the rotor with the electromagnets is stationary.

schnuepp2 no spectrum uses a different protocol. This receiver can be bound to FlySky controllers with AFHDS protocol.

schnuepp2 This ESC is meant for airplanes. It has no reverse function. Additionally it will get overheated in a boat because it is probably not cooled enough by air.

schnuepp2 the scale is in metric units (one indexline of this gauge corresponds to one hundreds of a millimeter) not inches.
