Got this for AP experiments. Built well, except I didn't like the wing-build for the spar. Very robust plane, flies well. My rig though has the following issues:

1. I built this with a Himax 2025 in an EPS300 GB. Runs a 1280 prop. The general sequence of events is that the propshaft nut can't resist the prop when the brake is applied, and disconnects in flight, losing the prop nut. The fix in the field causes the spur to strip... time for an outrunner or EPS400 GB (and maybe no brake on the speed control).

2. GWS Be-Found plane-saver. This beeps continuously rather than just when power is lost. Bizarre.

3. The camera mount failed once (must have been dodgy glue joint). Tie the camera on as well!

So this is awaiting maintenance / new GB or motor. Probably I'll just change the GB as I'm using an old CC Phoenix 25 on this, and that will probably self-distruct with an outrunner...

Great plane with the simple recommended mods (lose the upper horizontal tailplane surface, lose the prop guards). Not the easiest to fly (and flies on the power, not the wing!). But its neat, it is shaped in a car-trunk/boot-friendly way, and it works.

This is my 1st Multiplex plane, and it is a very simple build (except the battery compartment needed extending for my 3S LiPos, the rear balance ball bearing was a mistake, and the aileron covers were too proud of the wing underside).

The plane is pretty much stock (ie stock GB and 400 motor). I used a separate BEC as this plane uses 4 servos. One very nice touch is that the original box can be used for storage (with the tail sticking out the end).

Flying requires a somewhat different style vs other aileron planes, with a requirement to use rudder for good turns. The maiden was wrong because I did not pay too much attention to CoG (and no it won't fly with the stock ball bearing and LiPos way back in the battery comparment). More fool me. De-balled and balanced, it went very nicely on the 2nd maiden, except maybe it was a tad too windy for comfortable flight. But at least that meant a 2 feet landing run!

First warbird: used an EPS 400 motor to help with reported balance issues. Uses a 3S LiPo and no landing gear. Flies nice: I should fly it more often as its not bad for moderate windy weather.

This was my first completed balsa kit. OK, I started the MM Smoothie before this, but used this to expand my balsa-experience (and more importantly covering experience).

Nice plane; went well, except its not really suitable for general outside UK life: wet balsa warps, and most of the UK is wet for most of the year (ie the grass you land on). So currently semi-retired.

This is the new beater / anywhere plane, although it can be a challenge to fly as probably the CoG is not where I think it is

The original flew spectacularly well on its original wing, 350 motor and 3S LiPo although of course the motor didn't last forever. The wing is a bit fragile on these, even when tape-reinforced. I actually did a thread on this:
but never got round to doing the rudder.

With its SPAD wing its heavier (probably too much for the wire landing gear) and requires an EPS400 to balance. But it survives bad "landings" well, and is fast enough to stress the 9070 SF prop (so it will be replaced with a 9075HD). Good first SPAD IMHO...

Other Easybug (and brethren) threads:

Flies well enough on the EPS400 + 3S LiPo to not really need brushless power. But probably I should set the timing on the 400 motor correctly for this (geared) application, 'cos GWS didn't when they built it...

OK, this is/was a "beater plane". I never got to dial out the "high speed tuck" that can sometimes afflict this canard (even though it was running stock power albeit on a 3S LiPo).

Reference threads:

This is now a non-canard project awaiting some TLC. Adapted to have micro servos in the wing. Thinking about using some J250s on this (2? 3? 4?)

Useful reference on canard-free canards:

GWS Slow Stick with:
- Wattage Crazy Max wing
- MiniAC brushless motor + gearbox
- reinforced tail + steering tailwheel

Flown: rarely
