- |I have a few questions:
- |
- |1. Now that I'm installing 3 servos, I'm concerned that the additional weight
- |may be too much for the engine (a Cox 0.49 RC model -- Medallion?) Will using a
- |prop that is one size larger than recommended help any?
-
- No, not really. If you are worried about having enough power, I would suggest
- popping for an Enya .09 Pet, or an OS .10 FP.
-
- |2. The plans mark the center-of-gravity but say nothing about how the weight of
- |the radio components should be distributed from top-to-bottom. With a biplane,
- |will I gain stability by raising or lowering the components in the fuselage?
-
- Don't worry about it. Install the radio for maximum convenience, and best
- nose-to-tail balance. Vertical balance makes little difference on a plane
- like that.
-
- |3. For a beginner, how much movement should I allow in the elevator and rudder?
- |The original design did not allow for ANY downward motion in the elevator. I
- |adjusted that to allow at least 1/4" drop.
-
- Start with about 1/4 to 3/8 inch each way on the elevator, a tad bit more on the
- rudder. GET AN EXPERIENCED PILOT TO HELP YOU FLY IT.
-
- |Any advice on the installation of the radio components would be appreciated. So
- |far, so good.
-
- Actually, I would suggest shelving that particular airplane for a couple of years,
- and buying a 40-sized trainer and engine to learn on. An 049 sized biplane is
- not going to be terribly stable, will be very affected by wind, will seem very
- fast (due to small size), and you really want to use a mini radio for it. If you
- started now, you could easily have a trainer done for spring. Above all, though,
- get an instructor to help you. Talk to your local hobby shop about clubs, and
- go to a meeting or two. If you don't do this, you will be very likely to lose
- your investment the first time you take it out to fly it.
