I could try and get those measurements. If it were me I'd probably just measure you're current distance and just go to the hardware store and find a few different pound size springs to find what you'd like best. Measurements wont help if you cannot get the correct lb tension.

AKNick, thanks. Yeah, thats obviously a good point. However, have to order them online and thought I could try to get one set as close to original as possible. -Actually, when you mention in, I could also go for a slightly more HD to counter the RCFG56 in the nose to see if that save a few props....

Flew it over some tougher terrain. Handled great!

Well shoot! left handed drill bit? Glue something to it and twist it out? easy out? sheared? Stripped? Heat up the aluminum with a heat gun?

Tried all tricks in the book, but the bolt eventually snapped! Tried to drill out the remnant but the freaking drill bit wouldn't bite and I managed to damage the side of the screw hole badly.... Trying to get hold of a new RCGF 56cc prop hub now.. :sorry:
-In the mean time I have a RCGF45 at hand. Look like its about the same weight... so think that would be ok to get the bird flying again and while I repair my pride(and the 56cc):thumbsdown:..

Hello
I have a DLE55 RA gas engine. How did you program your gas curve in the transmitter? Did you also set delay on the throttle stick?

Many thanks for your answers.

Ugggg sorry man, that's no fun. I'm a little curious how it got stuck in the first place. Those bolts are pretty tough... guessing it was over torqued a bit (stretched the bolt) and/or locktitie? Given that the bolt snapped would concern me, either poor quality hardware or you did something it didn't like (we've all been there!). Darnit

I think my throttle curve is mostly mechanical. I try to follow this guideline as much as possible for a linear response.

I'm using a Futaba 18SZ, not sure what you system is. I use a splined throttle curve to get the response I desire through the AFR menu. Which usually equates to a gradual increase from idle (so the plane doesn't jump on you during take offs and you can feather a little throttle bumps on landings), a small plateau for hovering so you can maintain altitude, and a steep increase from around 70-100% input as our walbro carbs do not really have much effect there (have already achieved WOT past 70%). If you do a mechanical curve you'll be very close with minor adjustments.

As for a throttle delay, none. I do have an idle up switch set up, but I rarely use it for this plane. I'm not doing insane aerobatics and this engine has been very reliable for me.
