hi there cwick

the sickle weighs 4pound or close to 2 kilos seems very heavy but leaves you hand without throwing it and screems off only thing is the landings are a bit hot but once you get used to that there a breeze becarful of flutter i am working on resolving the problem as we speek trying some new ideas
cheers chris

4lbs? Would think it closer to 2lbs to 3lbs depending on the engine and the type of material used for the fuselage. My dogfighter is on the heavy side and weighs 3lbs 11oz. Think it'd be difficult for a sickle, built to spec, to exceed 4 lbs.

Nice to see these planes can take a lickin' and keep on tickin'...

Here's my sickle in progress - built to spec. Gonna be powered with a GMS .32 (once I put some time in on my dogfighter).

Had to temporarily tape a piece of balsa to the bottom surface of the front edge to keep it straight while gluing in the balsa filler. Used balsa on the back edge instead of coro(figured the coro would crush). Wing spar is two large Home Depot paint stir sticks(22" each). Connected with epoxy and fiberglass.

I will now eat my own words... my sickle AUW is 3lbs 4 oz.

Gained some weight from using standard servos for the elevons(+1 oz a piece roughly when compared to smaller servos), using an O.S. .46 AX engine and have a AA sized 5-cell NiMH pack(+2 oz vs 4 cell AAA sized pack).

Maiden report soon.

Planning to use a 10x6 APC sport prop for this plane's maiden on Wednesday. Heard of folks running 10x8s on this engine... now that'll cook!

Need to order a few of those props.

Got it trimmed tonight and balanced and it's ready to shake & bake!

.... is it Wednesday yet?

I fly a Debut w/ an OS .40 LA and the other guys at the club fly Sickels with OS .46 AX. I make a great target. They scream.

Maiden was a success tonight! I did some last minute eyeball trimming and fired it up to adjust the mix and high speed needles - still need to spend a little more time with these. Was starting to get dark so I wanted to get this maiden in. Walked out to launch this thing - oh man does this plane pull with this engine! My dogfighter pulls away without drooping but this sickle pulls hard and kept a flat line climb. I had it at a 30º angle up from horizontal. Opened to roughly 3/4 throttle and when I let go it pretty much snapped out of my hand and by the time I got my right hand on the stick it was up there a ways. Needed three clicks of elevator and two of aileron and it was set. I did a few loops and a few circuits and then landed it. Landing is hot but smooth. Gonna check a few things tonight and then get some more flights on it tomorrow! Currently running an APC 10x6 on that .46 AX. Plan to swap that for an APC 10x8. Zoom zoom!

It was very stable in the air for this short flight even though we had a good amount of wind. I changed the design a bit to move the fin back about 7". This should help with stability.

At any rate this is my new hot rod at the field. Thinking about calling it Melba Toast (see Dazed and Confused)

Funny to think this is the same engine model I run on my Sig Somethin' Extra which I was flying this evening as well.

After I get some more time on this plane, gonna have my friend get some footage and throw a flick up on YouTube like I did for my Dogfighter.

John Palica; In reading your reply you suggested the following:

you epoxy 1/8 X 3/16" spruce or bass wood strips into the flutes in the coro at both the leading edge and trailing edge in the area where the fuselage slot is. The strips are about 1" long and pushed in so they're flush with the edge of the coro.

If I understand it correctly. do you insert the srtips on the inside exposed fuselage slot cut out on the top surface of the wing; not sure I understand what this does; I have on some of my SPAD's inserted a 1/8" dowel the entire length of a flute like on a coroplast aileron, or elevators; I can see inserting a dowel the entire length in the leading edge flutes in the bottom side of the wing to prevent the mounting screws from crushing the coroplast.

Thanks Doug.

bamboo skewers are the standard spad flute reinforcer but then refer to spad 101"use what you got"
