  1. How much current will a park servo draw at 5V? Specifically this one: http://www.hobbyking.co.uk/hobbyking/store/__24764__Turnigy_8482_TGY_306G_HV_Ultra_Fast_High_Torque_DS_MG_HV_Alloy_Case_3_7kg_0_05sec_21g.html
  2. Ok, ordered two, thanks a lot.
  3. I'm looking for two small, high speed servos, 0.07 s/60degrees or less. These will go on top of a rocket to act as controlling fins, so the torque shouldn't really matter. Any ideas??
  4. Surely that would really damage the sponge inside?!
  5. I have a 3D printer so a custom mount is no problem
  6. Yeah, I think I will buy a new engine, any suggestions?? (slide carb)
  7. Yes, this one. Its not very new, the engine has had nearly 2L through it. I have stripped it quite a few times in the past, sealing everything up properly apart from the moving parts. And if you take the carb off and look down the hole, you can see the crankshaft, which opens up on the upward stroke. Then it closes and the piston goes down, and the pressure escapes around that opening on the crankshaft (which is facing down at this moment) and around the wall which holds it, up into the carb hole.
  8. Its a FTX Go.18, stock from the carnage NT. All the joints are well sealed, apart from the hole in the engine back plate where the crankshaft pokes through, and the around the port under the carb (not the carb seal itself). The front bearing where the flywheel is doesn't leak. Would the sealant work in the moving parts? I'm sure it would rip off at high speed and fall into the crankcase!
  9. The crankshaft in my engine is leaking out the back of the engine into the pullstart at high pressures (which means I get covered in fuel and green goo from the pullstart when I pull on it). Also,at higher temperatures, air leaks back out of the rotating port under the carb, around the side of the case and back up. This in turn restricts fuel flow as the pressure pushes it back. I don't fancy paying loads of money for a new crank, might even need a new case which means it would be better just to buy a new engine. Is there a magic way to seal it with something?
  10. Anyone else do the edexcel C1 maths exam today?? :119:

      not me but no1 son did. I assume mean A levels.

      Yeah, it was really really hard in comparison to the ones from the last years.

      Yeah he says it wasnt like the past papers, at last proper exams which make you think, back in my day.....

  11. Maybe the one way bearing has failed and your starter thing isn't turning the engine?
  12. Heat the engine up, with a heat gun or hair dryer, and prime properly (make sure the fuel tank is full and that fuel is flowing down the line). Then give it an extra 5 pulls without covering the exhaust. Open the idle gap, and attempt to start it with a few quick pulls. Is your fuel fresh? Does the glow plug actually glow when you take it out?
  13. If it jams it could be flooded. This is when too much fuel is in the engine and the piston can't compress the liquid fuel. Check your GP.
  14. Its a little disk that goes between the top of the piston sleve, and the engine head where your glow plug screws in. Some people decide to add a couple extra to make the chamber slightly bigger. If the parts look clean and there aren't any major cracks or bends, you could maybe try adding a tiny folded piece of aluminium foil between the engine head and the cooling head on the side that its leaking on to press it down more? EDIT: I'm not familiar with the DT-10, and from that instruction thing it looks like your glow plug just screws into the cooling head which also acts as the engine head, so that aluminium thing wouldnt work.
