Hi John Ineresting that you put the battery in the bay under the wing. I would have thought the plane would be tail heavy? Mine balanced perfectly (@ 89mm from LE) with the battery in the fuel tank bay! Also by having it there you can easily change the battery, without removing the wing, when you are at the flying field. I also fitted a larger prop as it strugled to get up to speed on take off. In the air it flys like a dream! Pity we have not had much weather suitable to fly lately. Tony

Here are some Pics and drawings:     I forgot to add to the drawing that the battery is fixed to the mounting plate using Tiewraps, with holes drilled to suit your battery. Edited By Steve Hargreaves - Moderator on 19/12/2012 12:20:49 Edited By Steve Hargreaves - Moderator on 19/12/2012 12:21:17

I recently converted The WOT Trainer to electric. Looked at the WOT conversion but did not like it. I have mounted the battery (4S LiPo) on 3mm ply and put it in the top part of the fuel tank space. Underneath I put the ESC. At the rear on this area there are 2x 6mm sq strengtheners on which I rested one end of the ply and on the front bulkhead I glued 2 more 6mm sq and then glued a approx 20mm wide piece of 3mm ply for the other end to rest on. I also glued 2 x 3mm captive nuts to screw the battery mounting to. For the motor i made a spacer which fitted the existing IC motor mounting position and the electric motor mounting plate. I will try to get some drawing and pictures to illustrate what I have done.

Thanks Guys for the replies   Lindsey, You did not clarify which was the correct length? I assume that the plan is right!   Kit, Had noticed that it was not in line so have packed out as you did.   Working on rectifying the wing, so will test fly after Southern Show.   Tony Hudson

Hi I have finished the build and have had 2 unsuccessful flights. In the first flight it barely left the ground and keeled over to the left , wing hitting the ground and snapping the wing bolt and breaking a horn on the wing. Analysis by my fellow club members that it was under powered. Back at the hanger a Watt meter revealed that I was getting barely 190Watts. It was suggested that I fitted a larger prop. I purchased a 11x4.7 prop and now got 243Watts on the Watt meter. Took it to the field for a second flight. This time it managed to leave the ground, but again veered to the left and headed for the ground, this time demolishing the cockpit and snapping off both F3 and F4. This time it was thought that it was tail heavy, even though I had put several oz of lead in the nose. I must add that my build somehow ended up overweight at 48oz. When I returned to the hanger and started to rebuild I noticed something that I had not checked before. On the spec at the end of the article the fuselage length was stated as 38 inches, but the plan it measures 36.5 inches ( and so does my model). What is the right dimension as the 1.5 inch difference would make a great deal of difference to the stability of the model? Since writing this (I had trouble posting it), I have found what was causing the crashes. The right wing was 6mm higher than the left wing. However I would like to clear up the anomily regarding the fuselage length.   Tony Hudson

Hi Guys   I am planning to build the Zulu ET and am gathering the materials to start construction. On the plab (Page 2) there are 2 peices that I can't identify where they go.(1) 6mm Medium Balsa Wing Support. (2) 3mm Medium Balsa Wing Support. Can anyone help me indentify where they fit?
