Excellent result Ron, the camo really works well against your concrete runway too laugh

Did you say on the video that you thought it was a bit nose heavy? I'll be interested to hear where it ends up balancing as mine is coming out 1-1.5cm back from your 7cm suggested fuselage only point depending on whether I put a 5000 or 4500mAh pack in. I'd guess that it will be pretty tolerant of the exact balance point in view of the wide chord and decent size tail.

Has anyone else played with the CofG?

It felt slightly nose heavy Bob but it also wanted to pitch over on take off and landing (rake on U/C ?). So I've replaced my 3000mAh LiFe with a 2100mAh one and moved it back by about 20mm. Hopefully going to get out again one evening this week (I'm working every day this week crying) and try it out.

Just checked back a page and it was 75mm from F2 without wings that Ron posted so I'm .5-1cm back after all. I'd call that good enough for now. In the past my trimming has been to move the balance point back until spin recovery becomes difficult then move it forward a shade on the rebuild face 1

Picture time! How to paint a spinner evenly:

The ESC is a neat fit, cable tied with a pice of non-slip matting underneath:

Battery tray fitted:

Sorry, just realised that the resolution of the vid isn't quite right, will correct it!

Bob , I like your colour scheme , for someone who says they dont like finishing , you make bloody good job of it .wink

 

Ron , great flight and video . The La7 looks so relaxed and on rails and BTW . if British Airways start recruiting again they could do a lot worse than hire you for a smooth landing course .

Cabin Pressure anyone ?

OK so I promise that this is the last of the photos, I just can't help it as the 'plane is just so good! These are some shots from yesterday's session. So no more photos but I will get a better vid as a new camcorder is on it's way!

I was lucky enough to be there to see Ron flying the La7. It really flies well and Ron flew it well. Nice one Ron!

The Curse of the Eflite Retracts strikes again. I'd got them installed with 1/8" shims to rake the legs forwards and 1/16 tapered to nothing to tip them outwards so that they would lock up with 3 1/2" wheels fitted. Tested several times, all ok so I extended the left leg to look at the cover mountings and the leg lowered an inch and stopped. Dead as the proverbial. Eflite don't do repairs or spare boards, been there before! Luckily I had a pair of Lado units handy which just needed the mount area extending by 3mm, they are now in and working but the 10mm Robart oleos don't fit the Lado units so I have some 12/13mm or so oleos on them. Of course the Eflites weren't going without a fight, one mounting screw rounded so I had to drill off the head and extract it with pliers. Not breaking my glasses last week would have helped my general mood at this point!

With the thicker oleos the 3 1/2" wheels were a tight fit on depth but 3 1/4" fit without the need to cant the legs outward. They only look a couple of mm thinner than the 3 1/2" ones but it makes quite a difference.

In conclusion, don't buy Eflite retracts, not even if they are offered at a bargain price. Not unless you like screaming at the world in general angry 2. Also Specsavers are doing two for one at the moment.cool

I agree with you Bob, the eFlite retracts on my H9 Hellcat are a nightmare, last night one 5mm connecting wire snapped off on landing, no other damage fortunately.

Didn't realise that Specsavers are doing 2 for 1 on eFlite retracts now.

I have a stock of assorted Eflite retract units with dead boards or broken leads and I could probably cobble together another 'strut ready' one to make up the pair but do i want the hassle?

Maybe I misread the sign in Specsavers. I think I was in Specsavers...thinking
