Default RE: Spot On 50 Build log.

I glued the canopy in place using RC56, finished the aileron controls and added the tail wheel assembly...quite a nice one for low cost 50 size plane. I didnt like how slack the trailing rudder cable was running so I replace the servo arm and added 2-3mm of offset. This worked very well. I liked the foam block for the Rx, I dont think I can build a lighter version so I'm going with it.

The plane now weighs 4lb, 11oz and still needs the battery/regulator and switch harness (another 4 oz) and the gear (3oz) so an all up weigh of 5lbs is not possible but we'll be close. I think AB models advertised all up of 5.3lbs is going to be tough to achieve for a stock plane using the even the lightest 60-70 4-stroke. I have taken more than 7oz out of the stock build and will only just beat it.

Without the gear the plane balances at the recommended CG and there isnt much room to mount the battery any further aft so I'm pretty sure we'll have to add a little tail weight...we'll see.

I'm just waiting on the gear now then I can finalize the battery and switch installation and minimise tail weight. Maybe another week or two to the test flight.
