I have a Thunder Tiger trainer 40 with an OS46LA. It flies extremely well and I am very pleased with it. After take off it will tootle around on half throttle and give you plenty of time to get used to things.

The steerable nosewheel snake can be routed through the firewall and not from under the fuselage. Use the outer hole in the steering horn at the front wheel end and the inner hole in the servo horn, this stops the steering being too sensitive. If you want to lock it in place you can use a 3A electrical connector block which is screwed into the servo mount tray, the metal snake can be fixed into that.

The front dowel, for the wing retaining elastic bands, needs to be a little longer. I made another dowel, but 15mm longer.

I fitted two balsa bearers and a thin ply deck to box the Rx Ni-Cad in to stop it moving if the aircraft was inverted. Velcro straps fitted to the tray also made sure that the RX did not move either.

I used a captive ball joint, or you could use a metal clevis, on the elevator snake at the rear, as the supplied nylon clevis was a bit too large for the exit hole.

Check that the elevator and aileron balsa control rods do not foul any fuselage formers.

It is worthwhile trimming the centre wing ribs, to suit the aileron servo, before you glue the wing halves together.

I coated the area around the fuel tank with fuel proofer.

Clear tape over the pinstripe, which goes centrally fore-aft, will stop fuel affecting the adhesive later on.

I also fitted larger wheels, with firmer foam tyres, as I fly off a grass strip. This is better for going over the bumps, especially on wet grass.

After the first flight the rates were set at 75% for aileron and elevator.


I hope this is useful,


Regards,

Sarah
