It has been a while since I posted anything here - I tried to cut two fingers off and moved house so that slowed me down a bit
But with a bit of prodding, I built another Peter Rake prototype - a 48" Farman Moustique light aircraft. Quite a simple build but with a lot of character - wing cables, that undercarriage etc. A product of the 1930s, it make an ideal simple scale model and flies well.

Since I missed the 2006 build-off due to the above circumstances, I thought I'd do a design myself of an aircraft I have always liked the look of - the Henschel 129 Tank-buster. A quick and dirty build was decided on using Depron for skins and balsa where dictated by structural needs. The almost-end result is OK but would be better rebuilt in balsa and ply and maybe slightly bigger than the 48" span.
After a few teething problems mostly related to excessive control surface throws, the model flies great. A lot faster than Rake models but exciting!

The current model just completed is another Rake prototype - the AVRO Arrowscout. An AV Roe racing plane from 1914 - no doubt a derviative or pre-decessor of things to come! 36" span, fairly easy to build and flies well. Build log at:https://www.rcgroups.com/forums/showthread.php?t=720548

I wanted a Trainer that was a bit less benign than the Telemaster and built a new design by Peter Rake (who else!) which was loosely base on the Ryan PT22 and similar 30s trainers. It is quite a large model designed for 500-600 sort of power levels - I am using an E-Flite 25. The maiden didn't go so well but it is now repaired and awaiting some courage from me. I thing I had CG marginally too rearward and the motor had slight up-thrust instead of neutral. Was very difficult to control in the air. In fact a later flight destroyed it! Most likely reason was that the aileron hinges had not been glued in

The other model completed recently is a tiny IPS powered design also by Peter. The Duigan 1913 tractor Biplane. This 24" model is yet to be flown. It was great fun to build but at 6 1/8 oz AUW, will need a very calm morning! Update : It flies! Needs a little nose weight I think but otherwise floats around quite well.

My 36" SE5a was recently sold to be used as a static display model, so with some of the proceeds, I bought a laser short kit from Charlie at Manzano for a bigger SE5a - a 54" version also by Peter Rake. It is almost exactly the same construction as the 36" so should be fairly easy - but HUGE!

To try and push my personal envelope a bit, I decided to build a simple twin. I chose an oldish design by Laddie Mikulasko - the Dornier DO-23. An aircraft from Germany's military buildup in the '30s, it is simple, has character, big wing area and should suit twin bell outrunners well. 60" span will give it some presence and it seems a stable design. She flies very well - slow and majestic just like an old bomber should. I mixed flap and seperate ailerons to give differential and flap function but have yet to decide if it is of benefit. Runs well on a single 1700 mA 3S LIPO for about 10 min. Only draws 5-10A at normal cruising. Great model - I want to do another multi now!

Another more complex build to stretch my skills a bit is an IC conversion of an old Gordon Whitehead design from the 70's - a 46" Hawker Hind/Demon. This is a very complex build for me and I'm being very cautious - luckily receiving help from these forums and from Gordon himself.
Still a way to go with the airframe completed.

A cold 2006 winter saw quite a few projects completed and a few more started . Some of my flying compatriots have been a bit critical of my mad pace, but I try to reassure them that I'm cramming about 20 or 30 years of non-experience into a couple - a lot of catching up to do!

Finished over the last few months are four Peter Rake prototype builds - Baboon, Hanriot, SE5a and an FE8 WW1 pusher.

Building a never-flown-before prototype is a fair responsibility. Not only do you need to build as per plan or at least check any changes with the designer, the design and plan must be verified, the model finished in reasonable time AND it has to be test-flown. Even more importantly, it must be flown, debugged, photographed and written up without destroying it - makes one nervous and careful!

The Baboon was finished and 'Flew off the board' no problems - it is a big model for a 42" and flies as slow as a kite.

The 36" Hanriot had a few teething troubles with balance and power but with that corrected - flew fine.

The 36" SE5a is a well-proven design and no trouble was expected from it so I chose to try out a few fine-detailing ideas. It looks good and flies well.

The 43" FE8 was Peter Rake's first pusher design and we had some fun getting used to it but it is now one of my regular flying models and performs well.

I have always dreamed of flying a very detailed, accurate R/c model - I used to build 1/32 plastc kits and "super-detail" them, and had this desire to build a much bigger model and dress it up to the nines! With no flying skills whatever, this was a bit ambitious hence the preceeding models. As my flying ability has improved (a little), I feel more confident that I can get a plane into the air with less anxiety than 12 months ago but with only 35 or so hours of experience, have a loooooong way to go!

Currently, I'm building a couple of prototype designs for Peter Rake - an FK-24 "Baboon" biplane, and a small Hanriot monoplane from 1913. Easy builds but as they have never flown before - a bit of a responsibility!

A 48" close-to-scale Bleriot XI is slowly progressing and being described on rcgroups electric scale forum. This is a long-term project and other models will be built to gain building and flying experience in the meantime.
Bleriot: https://www.rcgroups.com/forums/showthread.php?t=445162


Dream list? - like most scale modellers, it is endless and expanding :

A WWI pusher - DH2 etc
Something bigger - 54" SE5a or similar
Brisfit
Hawker Demon or related late Bipe
A simple twin - I've never made or flown a twin
An indoor scale electric machine
He-111 - a favourite
Supermarine Walrus - love it!
etc, etc.......

What I dont have much interest in:

Cap232
Giles
Ultimate
Pitts Special
you get the picture.......

So many planes, so little time....Pat

I got hooked on scale after the Beaver and as is normal for me, jumped in at the deep end with an electric adaptation of a '50s Westland Lysander plan - a free-flight model so was light and should fly on its own almost. This was also my first real build thread on rcgroups. The Lizzie flew great first time with its marginal 480 can motor. It too, suffered from the dreaded stalling and after many rebuilds, was retired before it was a complete wreck! An unsuccessful WACO biplane was next and then began my love affair with Peter Rake's designs. First off was a 48" Eastbourne monoplane - still flies great. Then a 48" Fokker EIII Eindecker - my best flying model to this point. About here I decide the 45-50" span model suited me better than smaller and I still plan around that area. Somewhere in there, I adapted a frebie plan off the 'net for a Telemaster as a robust trainer - flew very well with a variety of brushed and brushless moters. Recently retired as I wanted the gear elsewhere.

I had a visit at Christmas 2004 from my brother-in-law who was an r/c plane enthusiast. While talking over a beer or three, he suggested that with my background in electronic engineering, and old ship models, I should have a go at electric planes! At 60 years of age, I'd never been at the controls of an R/C plane but as a private pilot for some years (20 years ago) I figured I knewthe basics of flight but had a lot to learn about r/c flying
First trials were with a GWS Pico-stick - unexciting but a good first plane. It lasted about a month and failed to avoid several trees and finally a very solid picket fence . Following a moderately successful Depron Cub (I learnt about CG) was a GWS E-starter - ailerons etc. That lasted about a month too but gave me my first ROG and more experience. A 40" depron Tiger Moth was my foray into scale - from a modified balsa plan. That model taught me about tip-stalling and the danger of slow flying That lasted two months. A 50" Depron Beaver was my next plan built model - my best to that point and a good trainer. It was retired after 3 months of hard work and harder landings.
