| I have no experience of constructing for electric so can be of little help except to state the obvious. It makes no difference where the motive power comes from be it ic, electric or a wind-up elastic band, so long as there is sufficient power it is the weight, lift and drag that will determine the success or otherwise of the model.
Being a scale model, there is nothing you can do about the lift and drag and as you have found out, to get the equivalent power from electric, with reasonable running times, involves a heavier power source so to keep the all-up weight within limits weight has to be saved elsewhere.
The only place to save weight is in the areas of the construction that are not visible on the finished model, but as the all-up weight will be the same , or very likely slightly more, strength has to be an issue.
I wish you luck! |
