Hi all, a little late but as promised, the beginning of my build. I'm actually pretty advanced with fuse, wings and tail feathers close to complete bu I'm afraid i've not been diligent in taking photos so will have to jump from here to where I am now for the next installment. Great model Lindsay. Cheers, Rob

Hi all, anyone building a one of these from the RCM&E plan yet? I have a TopFlite Elder 40 with open rear fuselage which I love so couldn't resist Lyndsay's masterpiece. I made a start on the weekend and have got the fuse, wings and tail surfaces pretty much complete. Will post some photos tomorrow. Cheers, Rob

The most visible difference is the choke mechanism. The R120 throttle arm/barrel pulls sideways to choke the engine. The 120 has a more conventional design. Is explained more clearly in the review articles below (possibly the ones you already have). I have an as new 20 year old R120 in a 95" Storch.

Be careful, you would be talking about the SPC voltage input on the Hitec Optima series of receivers that is rated at up to 35V. This input only powers the receiver circuitry, not the servos. Bear in mind that if using the SPC input, you still need to provide a separate battery pack (4.8V, 6V or 7.4V) to power the servos. If using a 7.4V LiPo or equivalent then you need to be using servos rated for 7.4V. Hitec (and most other manufacturers) make a range of high voltage (HV) servos **LINK**. Most manufacturers specifically advise against using their standard servos with 2 cell LiPo packs - although the nominal voltage is 7.4V, fully charged they will be around 8.4V. Recommend you use a regulator or go for HV servos. Rob

Here's mine. I used SIG Koverall and dope (the only way to go) and thein paint. Power is a 56 Saito. Lovely (if sedate) flyer. Build photos on my club website here. I can post some more photos of it in flight if you like. One thing, there is an issue with the wing hold down plate as shown on the plan - it fowls the rudder / elevator push rods. TopFlight have issued a Tech Notice re this problem. Happy to provide more detail if you like. Cheers, Rob

Hi all - here's my Jitterbug rendition. Is it the first downunder? The maiden wasn't very inspiring but after a few minor mods wow - its everything that has been said about it. At first I couldn't get it to lift off the ground. I found that as drawn the the wing seat on the plan (apart from being too short in chord as has been well documented) has a small degree of negative incidence. After packing the te, bringing the c of g forward another 5mm and increasing the elevator deflection I have a fantastic aeroplane. I made very few changes, the main one being to bolt the undercarriage on with nylon wing bolts. Other than that, stock standard with an OS55 AX. Thanks for a great model Alex and now for a change of pace I've made a start on Dave Royd's Luton Minor. Cheers

Siebel Si 201 build with lots of pics
WOETC (Rob) replied to Ton van Munsteren's topic in RCM&E Plan Builders
Sorry Ton I didn't put that very clearly. The "-" was meant to b a hyphen. I should have written "downunder - +26C". Although we do get snow in the mountains during our winter (July/August) I don't think there is anywhere in Australia that gets down to -26C ever. 12 to 15C would be about the absolute minimum. In Sydney where I live the minimum is about -2C a few days a year and never any snow. Have almost finished the fuselage. I'll post some more photos later today. Merry Christmas, Rob -

Hi all - the traveller returns. Busy with chores getting ready for Christmas but I did manage to get the fuselage top & bottom cut out along with F2, epoxied the boom in place and just couldn't resist trying the wings on for size. Have a good Christmas everyone and keep warm. We even look like having an unusually cool Christmas downunder - 26C and a bit of rain; change frm the usual 35C + Cheers
