Not near my shop for a fewdays. Will weigh real soon - E

No drama just curiously. Drag and stuff will be different too

My expereience with EDF twins vs. prop singles and twins, is that the EDF when off has a lot less drag than the prop. I flew the water bomber at low throttle and no throttle and she did very well. The stall point changed quite a bit when I fitted two 3S 5000mAh packs. Had to keep up the airspeed quite a bit for landing. With two 2800's I could "float" her in. The landing gear handled the weight well and did not side tip as I had feared.


I need to redesign the wing struts. The plastic clevises pop off all of the time. The wings were fitted with CF spars which made them very stiff and I may dispense with the struts - may not! Decisions, decisions.....

.
In mine i installed a CF spar (not very big .. a flat 5mm X 1) from one nacelle to the other... glued both wings with slow epoxy and also afterwards glued a 3mm plywood seat to avoid chaffing the rear screw supoorts (wich get crushed over time) .. and went away with the struts..

Never had any even minimal wing flexing.. not even in the air..

Granted i dont fly aerobatics with this (a roll and a loop from time to time but mostly scale flying) but wings seem quite solid..

Eric..If you really want to keep the struts you may want to check out the Dynam Catalina or the Flyzone beaver https://www.google.com.au/search?q=f...Y2GQqvcjuLk%3D
