Thread: Torque rods vs wing servos
04/12/2019 17:03:34

One small benefit of two central servos is keeping the mass in the middle of the aircraft but doubt it makes much difference. Have a couple of models with this system an they have worked well for years.

Thread: 140% servo travel
27/11/2019 21:50:22

Would think that as long as the servo is quiet, no hum or sound it is under strain then it is ok.

Problem with rotary servos is that at these extreme movements you do not get as much extra movement as the percentage figure suggests.

As above JB should do the job, if you can roughen surface a bit it will help.

Very nice pic's capturing much of the detail like the " Toblerone " buffet stall warning strips on the inner wing leading edge.

Thread: Laser Engines - Technical questions
15/11/2019 14:46:29

Centre of gravity problems were common with many designs.

Short Sunderland must be an extreme example. When it was found the wing needed to be a lot further back it was decided rather than redesign the hull the wings were given sweepback at the root.

They did not bother to realign the engines so they toed out. This lost some performance but was helpful in engine out situation.

Hawker had the same CoG problem with the full size and bolted lead to the engine bearers.

Our little village memorial has seven names listed for it and one unknow, a sailor from where or which side is not known.

In England and Wales there are 53 " Thankful villages " Villages where all who left to serve in the Great War returned.

There are just 14 " Doubly Thankful " village's where all who served in both world war's returned. Two of which are here in Pembrokshire.

Thread: Trimming Question after Crash :-(

Like Steve I am not a glider man but I agree it may well be to much elevator movement.

I have a Seagull AT6 and I had to reduce the recommended elevator movement a lot. At least at lower speeds it behaves but flat out it can still be provoked into a spin with just the elevator.

rNot had one myself but a friend did and used to manoeuvre it had to get the interplane struts to pop off ! laugh They were only fixed on with clothes fasteners.

Thread: The "drooling" stage?

Yes ASH, Only had three flights so far and agree it is a lovely flyer. Have thought to use fiber tape to reinforce the cowl. Easy to land slowly with a flop onto the grass much like the full size F4F 's when ditching in the sea on you tube video's. John
