Hi guys, tried out my smoke system in flight yesterday, quite pleased. I used MT smoke fluid and also tried ordinary Diesel. video here.
Also got some inflight footage with the MT fluid, here
On one occasion I dont know why, the system malfunctioned and had to land with the smoke tank full (125ml). ( poss clunk bent back on itself) Didnt make much difference but landed a bit long.
With the extra weight and around 30 degrees yesterday, 90 degree cross wind and long grass, the plane struggled a bit, so tookoff on tarmac and landed on grass after that.
See page 53 for the smoke system set up, with no more chanels left, i used undercarriage up for air to pump the fluid out, so no burnt out electric pumps.
I think a slightly larger opening would give a better thicker flume, so will try next time.
Ref the nose leg, with my home made oil filled damper and soft spring, what a difference. Really pleased. In the video, this was the worst bouncing of the nose that occured all day. All other grass taxiing and landing was really smooth. On last landing, used full flap and the nose stuck to ground well, with out being shot up in the air.
I had increased lenght of my main gears by about 8mm to prevent another occurance that i had last month, when the model became airbourne again after a perfect landing, probably due to a too high angle of attack with model sitting on ground.
I do think the model would benifite from a high angle of attack for take off and low angle for the landing, so i might design an extendable nose leg, to give me the best of both worlds.
The LED light, does not show up too well on the link, but in the flesh, it was brilliant. At 3 volts it was ok, but with 4.5 volts, it could be seen clearly even with the model side on at 90 degrees. The sun was a killer yesterday and we can only fly in one area, so spent all the flights trying to avoid it and you guessed it, as soon as i landed the clouds covered the sun. It was so bright, i wore my prescrition reactalites with polarizing modelflight glasses on top, so it was a credit to the light.
