I just picked one up and plan to install my DLE20 in it. Since the DLE is out of another plane, I already have a tank setup for it that happens to be the same size, which is good, Ican use the one from the ARF in my other plane the DLE came out of.
For starters I am thinking of using Futaba s3010 servos for the ailerons and high torque MG servos for the tail, and an S3004 for the throttle. Any problems with the 3010's for the first few flights? Eventually I will pick up another pair of the servos I got for the tail when I have more cash for them.
Would there be any issues inverting the DLE20? Inverted is "normal" for a gasser.
Where would be a good place for the ignition? Any place it will fit.
Where would be the best place to install the fuel dot, and switches, and any recommendations on mounting the fuel tank and batteries? Fuel tank can go wherever you want: the carb is a pumper.
Would using flaperons be good? No. One of the outstanding characteristics of the 4 Star design is its slow flight capabilities. If you can't fly a 4* slowly, consider some other hobby.
Where I fly the field is surrounded by a corn field on three sides, and making a landing over the corn would have to be spot on or there would be little runway left to stop. Had to make a downwind dead stick the other day, ran out of runway. Iwould like to be able to drop right down once past the corn, so would that work?
How will it fly with a MAS 16X8 prop? It will be OK, but 17X6 will be better if you have the ground clearance.
Does it fly well with a magnum .91 4 stroke? No. The 4*60 flies well on a .91 four stroke.
The DLE was originally purchased for a Top Flite GE P-51 which is still being built, and it may go into it when it is ready, so for a backup I have a .91.
I think that pretty much covers all my questions.
