Wet field

Went to the field in the forlorn hope of someone being there.. not to be.

FIELD SECURITY .... The gate padlock issue seems to have been resolved with 'farmers' twine' !! This is now the only security & whoever has done the job has been to …

Down thrust

Post by Marty on Fri Apr 16, 2010 4:45 pm

I am experiencing an alarming climb rate on my easy glider on full throttle? power? mmm dunno, it's electric so I 'spose it's power ......
Tim just handles it by feeding in down elevator but I really, really don't like it the way it is!
I've just drawn up the motor mount with autocad and had a play with shims, if I add a 1mm shim (read washer) I can bring the thust line down by 7 degrees. is that a lot?
The plane really does climb like a balistic missile as it is!

It's normal for EG - unfortunetly.
You can try to mix throttle with elevator as well.
My friends tryied with even more degres - not big difference.
EG doesn't like powerfull motors , try to use slower prop than you have now.

Here is picture how my friend managed to eliminate that problem - he flies with FPV stuff onboard and long distances Smile


At this angle problem with climbing was eliminated but - motor is where it is - didn't help with motor at the front.

Thanks for that, I don't really want to alter too much as I wanna use it as a glider but I'm looking at also doing my "A" with it.

Appart from climbing problem it's an excellent glider - it will do "A" without you touching the sticks Very Happy
Have some play with differential ailerons, and mix some rudder to ailerons Smile

Give it a shot, im sure if all does come to the wors and it sucks it to the floor (which it shouldn't) it will bounce as it is only epp foam!

Hi Marty, I can appreciate that the " climbing under power" can be troublesome for a beginner - I know you have flown gliders before, but I think I am right in saying that power is new to you ? As I said on Tuesday, its not a "fault" as such ( although the EG does exel at it ) and any aircraft will climb as speed increases - indeed the correct way to alter height is by changing power NOT pitch. Elevator controls speed due to the altered AOA, if you apply "down" elevator the model increases speed and vicky verky. As I suggested, you could, if you find it just too much, mix a little down elevator with high throttle, and also I found the model turned better with coupled rudder.....again an easy mix to set up but I would prefer you to just get used to applying rudder manually as needed - tis good practice.

It's only the bullet like climb which is fazing me ..... it's a practice thang! ..... Just need more time on the sticks (more batteries!).
Tim and I flew it during the week, the wind was across the strip (not good) and probably 8 - 10 knots but a little gusty (which for me was little problomatic) but we used to have a saying: "train hard, fight easy".
It's a good thing to push outside the comfort zone as thats the only way to progress. (and of course the reassurance of an instructor to recover things if it all goes pear shaped! )
