Engine ran successfully today. Took a few minutes to draw the fuel up, understandably as new tank and empty pipe work.

Once it was primed it starts easily. 1800 idle, 6900 WOT, 22x8 Xoar, unknown canister. With the model warmed up I got my balance out to measure the pull, 12.8kg, on a plane which weighs 9.6kg. Should be enough?

No not yet. The weather has been against me all week and next weekend doesn’t look very special either.

Still no maiden

ive decided to change the UC. The original had too much flex for my liking. I’ve bought a carbon fibre one from AliExpress. It’s for a Yak 50cc and has almost the same dimension as the old one. The CF has some flex but no way feels like a a jelly

Cool,,, I’m still using the original undercarriage,,,,

it did alow the spats to touch the wings during a heavy landing .

keep the approach low,,, even if you need to drop it in keep the last bit nice and level

Make sure you carry out stall testing before you get low on fuel,as you really don’t want to be rushing things

Cheers Bert...sound advice that I will keep in mind yes

 

the spats will be off for off for a while...they’re only placed on the wheels to see if it’s ok

Maiden today. Flat calm. After the usual checks and double checks ( yes...trying to put it off). Took it out, opened the throttle and she gently lifted off.

Only one click of down elevator was needed. Low rate ailerons and high rate elevators used.

The CG that was worrying me ? A complete non event, it seems ok slightly further forward than book. And I’m going to keep it there. Very little down elevator on inverted. Roll rate good- nice and axial. Right thrust just right.

Landing was a little fast.....no wind and my worrying about tip stall. This resulted in a broken wooden prop and the loss of one tailwheel spring. That’s it.

There is no wing rock at all at low speed. She’s a beauty heart.

P.S. Bert, the new UC worked a treat. Needs the idle setting a little lower for a slower approach.

yes Once you've flown it a time or two, I reckon you'll be saying,"Tip stall, what tip stall".

She was well behaved. Showed no signs of getting upset. Even on the final turn for the landing - the worst possible place for a tip wing. Steady as a rock.

Well done Cymaz. It’s a big relief to get that over with. Sorry about the prop, but easily replaced! yes

I used to break the prop on my Glens Cap every other landing. It was my first large model.

The trick is to fly it under power all the way to the ground rather than reducing the throttle to tickover and gliding it in. That's how real un's do it and it works for models too.

Getting used to landing it....it just needs to line up, slow to a crawl....adjust throttle to lengthen the glide.

As the weather is poor I’ve done some fine tuning ( Mrs C calls it tinkering in the garage). The throttle control was a little “peaky” at mid throttle onward with not much happening in the first 1/4 of travel.

I found a really good video about setting up a linear throttle travel
