|Devastator.||Twin Depron Devastator.|
Later, in the January 2012 issue of RC Model World, I did a 36in span Depron version, named Devastator. This was made in single motor and twin motor versions, both for brushless motors. These models performed very well in lighter winds but, of course, due to the soft nature of Depron, they do suffer from hanger rash if treated the way I do! A finish using the Poly-C system, however, does harden up the surface. This model is plan No. MW 3520.
|Dominator36S.||Domminator 36T. This model had two motors.|
In between these models, I built another two of 36 inch span, this time of all-balsa construction. The wings were made from ¼" (6mm) sheet balsa and had a curve planed into the top surface, so forming an airfoil. One model, the Dominator 36S (single) has a single brushless motor, an EMP C3536/5 fed by a 3s lipo, 8x8 prop giving 365 watts with a weight of 3lbs 4 ozs pounds. This is easily hand launched as there is plenty of thrust to get the model away safely with very little sag. With a 9x6 the sag disappears! The watts/pound for this one is 112 watts/lb.
The second Dominator was the Dominator 36T (twin), a twin motored version with two Warp 4 BL4-15-3, 2,580Kv motors, 260 watts each on a 3S 3,000mah, 30C lipo. The props are 4.75x4.75. The thrust is not enough to hand launch so a bungee is necessary. One day I hope to get the plans finished and sent off to Q&EFI in the hope that the models may be accepted for publication. This model has a power loading of 153 watts/lb.
|Dominator 44.||The latest model in the series, the Dominator 44.|
All these models have been interesting excersises in designing and test flying due to their different wing shapes which has required some experimentation in finding the correct longitudinal balance positions. There have been quite a few disappointments along the way which have been overcome by analysing each crash and rebuilding. All but one has survived and all are still flown, even the damaged one may be repairable.
