What did I fly last Friday ?
Well to begin with I flew the Bushwacker with the new 1050kv motor, it was much better plenty of power yet I was still able to cruise around at a gentle pace too. I landed it only to discover one of the wheels I had recently bought had broken (cheap plastic Chinese
), should have stuck with the original foam ones I had on, wouldn't have minded if it was a heavy landing it was smooth.
Next plane was my Spitfire, turned out the grass was a bit long for my weak landing gear so it wouldn't take off conventionally I had to hand launch. The flight went well, no trimming needed I got a good 8 minutes flight time very un-eventful mainly circuits and the odd rolls. Landing was a disaster as expected the wire undercarriage just folded when she hit the runway. No big issue, I removed the landing gear and continued to fly the Spitfire for another 3 flights just belly landing it, the wheels got transferred to the Bushwacker for later.
Next plane was the F22, I set the throws to low and hadn't enough elevator, so pranged the nose on the first attempt to hand launch. After that with full throws and a bit of up elevator trim, it flew great. I had forgot just how much I enjoyed flying this plane, I was doing rolls, inverted, low passes it was great. I had another two flights with it before it was time to move on to the WOT trainer.
Its a nice model which weighs in at 2kg with a 4s 5000mAh battery, I have not flow it since last year just after converting it to electric from IC. It took off effortlessly and cruised around at under half throttle, I kept the first flight fairly sedate and sensible and after a good 8 minutes landed it with 60% charge left in the battery.
I swapped over the battery anyway and took her up again, this time I got more adventurous with loops, rolls and some low passes, possibly one of the more pleasurable flights of the day. Foam planes are good fun but you cant beat the feel of flying a balsa plane.
Finally it came around to the Edge. I was hoping John, one of the more experienced fliers from the club would turn up and maiden it for me. Unfortunately it was getting late in the day so I decided to maiden it myself. Bit of nerves kicked in but I've been there before, I taxied her onto the runway and opened the throttle. Straight up into the air no problem, plenty of power. I eased off on the throttle and it flew straight as an arrow no trim needed, I continued down the field and made my second turn to return up the runway for my first pass. However, just after my turn I noticed something fall from the plane it was my removable undercarriage. It didn't phase me the plane was still stable and I was easily able to control it even with the weight change. I continued to fly a couple of sensible circuits and fetched it in to land belly style.
Everything was fine, all in one piece loads of charge in the battery too, so after retrieving my undercarriage I hand launched it and flew a second time but without the undercarriage. This time I got more adventurous, inverted (amazingly no elevator correction needed either), rolls where smooth and without loss of altitude (this was still with reduced throws), I continued for another 4 minutes flying around and enjoying the experience.
However, all good things have to come to an end and it was time to land. Unfortunately the third landing, all be it identical to the last two wasn't a great success. First thing I noticed as I approached was one of the side force generators had come off (no damage to the wing fortunately, it could be easily glued on). I wont be re-fitting in fact I have already removed the other side, the plane looks better without them.
Sadly that was not the full extent of the damage, I noticed the motor was pointing lower than before. Upon close inspection It appeared the rear support bracket where the power pod glues into had been damaged (probably by the prop hitting the ground first). Removing the top hatch I could see the damage better. It was a weak spot and in hind sight I should have added extra support in the form of a sheet of 1/16 ply on the motor side of the bracket, which would have provided more support and bracing.
I hadn't set the brake on the ESC so the 12x6 prop was wind milling with the motor off, that wouldn't of helped. Its been proven that a rotating prop has more chance of digging into the ground on impact than a stationary one, leading to less prop damage and issues like mine. I could have added extra tape to my landing gear to provide a tighter fit in the slot too. All these measures are in hind sight.
To complete the repair, I need to remove the cowl from the front fuselage then remove the damaged bracket. I then need to make a new foamboard bracket with an identical 1/16 plywood bracket glued to it. That should sort out my problem, combined with my landing gear being glued in place for all future flight.
Sorry its so long Timmy I know you hate my long narratives, just pretend its a bedtime story it will help you sleep.
