Hopefully you have thrown away these brown jobbies bands that come with a lot of kits and are using  5" or 6" white bands.

Try sleeving with fuel pipe as this will give a better seal

At 11 on a Saturday night,  need you ask     Checking my low fliers have the correct measurements   - now on 50 cL

Thanks for the information and it looks very straight forward.

KC   Very interesting as I have a wing to make which is not flat bottomed and the jig provides the answer.   What the chances of a close up of your cutting tool ?    

A bit common sense needed here as I am interested in the jig as I am sure many others   Can a moderator post the link

Stephen    I am at exactly the same level as you, however I have managed the upside down bit for about 5 secs.  My problem at the moment is, for safety sake, I do it at high level and then the 60+ vision impairments come into play, making it harder.   I hope the experts will come in, but I have found that increasing the rates and speed make things happen easier, albeit  much quicker.   Were all your aerobatics with your Boomer and if so then your repairs appear to have no effect.   Been like a bear with a sore head today as it is so windy.  Forecast for tomorrow is good and hope to get a few flights in as I'm then off for a weeks hols down the borders.

Michael   Can you move the engine forward  before adding weight?

I understood the bung in the fuel tank is for that purpose only and in the Boomer I tightened first before fitting.  I packed the fuel bay with sponge to hold the tank with styro foam to stop it falling out.   I'm afraid the build instructions on the Boomer where of the same standard.   One of the first actions suggested is to attach the landing gear so you then have this unwieldy fuz to attach everything else on.  This was the last bit I did after all other bits attached.   Hope this helps and good luck

 Would not like to guarantee that Stephen.  One of our experienced members told me that if you can glide on to it and it may stay on the top.    My ventures into the rape so far have been two head down at full tilt and one when I did manage to glide and did not go deep.   Have managed a few flights now without any failures and hope it will continue

Andy   For exactly the same reasons I nearly lost two models and decided to take precautions.   Bought from  http://www.njttechnical.co.uk/  I was impressed by their service as they communicated.   I am hard of hearing and could hear  it at about 15 metres +.  You still have to take all he correct action when it goes down to mark the spot with your aerial etc and then go searching.   The rape surrounding our field has now lost the yellow.  I am told that it now binds together on the top and is virtually impenetrable.  You have to crawl under it and pop up and down to get your bearings.   Hope this helps  

I did it the other way round.  My Magnattila is such an easy model to fly that I stuck with it to sit my test.  My first Boomer has just been cremated in a solemn ceremony as it was now beyond repair.   I now have a second Boomer and with all the less weight is a joy to fly.  As has been suggested, I am continuing to do circuits and more so landings, just to make it so much easier.  Have not bought a prop for over 15 flights now  or repaired the undercarriage.   I,ll let the expert advise, but have learned with very low rates, now putting in a higher rates and this has changed how the Boomer flies and has upped the flying level along with the pleasure.   Good luck 

Well done Stephen and as Bruce has said this is when the learning starts.     After my telling off,  about using the wrong thumb for landing, I have been practising and have been delighted, with the results.  It is a great just to see descending as it should do, under my control, and then making a soft landing.   As I said, now the landing begins.  I am still doing circuits and going up and down the flight line just to say I am control.   Again, well done Stephen and have a dram on me tonight.

Peter   Have measured on the plan from my mag and the sizes you show in red for  T4 and T7 are what you say?   What is the total length of the Fuz.?  I have 682mm plus 335 which is the front of F1 to the split line aand then from the split line to end of doubler.

Obviously the sun is affecting this man  - a Magnattila with and electric motor, never heard of and he should be shot at dawn.    I have an old Maggy with an OS 40  4 stroke and it is an absolute delight to fly and listen too, no point in looking the part but you have to sound it..  I used it as a trainer and it exceeds my Boomerang by a mile.   Have to say there was a flier at the field today with an electric Maggy and it was a delight to see it fly so smoothly.  It was also immaculate which electric allows.   Good luck with your build and keep us posted.  

Bruce   Mine is  a tail dragger, however because of the extra weight I put in when I repaired it and more importantly the fact that I am not landing properly,  bends rather easily, even though its two loops of wire.  Gave up on alloy units as I would rip them out and half the fuz floor.  As the Boomer got badly damaged last night, I am not going to repair it.   Currently stitching together  another Boomer and I will leave it as a trike and see how I get on.  Will be at the field tomorrow and will practice proper approaches with my Magnattila.  I should have Boomer 2 ready for Sunday and will see how it goes.

I have the same problem with undercarriages.  Been told I am using the wrong thumb to land.  I am landing with the elevator when it should be the throttle.  Went down to practice but still damaging models so achieved nothing.   Good luck with your test and then the real learning starts

Looked at the Ripmax site and neither of these models appear to have undercarriage and are hand launch.   You should be able to land them in long grass but you might loose them ?

Well it had to happen.   Down at field on my own tonight with a couple of models, slightly blowy but good experienced.  First up was my repaired Boomerang and it had improved.  The previous night I had gain a lot of knowledge from an experienced member.  It looked as though my incidence angle on the wing was out resulting in a tail down type attitude and it was also considered I had too much movement on the control surfaces.  All adjusted today and down we went.  Had a couple of good flights although a bit choppy.  On third take-off, all was not well and she dived into the field.  Fortunately it was just at the edge and I found her very quickly.  Wing burst and some damage to the fuz.  It could repair but I think it is time to call it a day as it is not able to perform my next stage up, Bronze + up here in bonney Scotland.  Brought home and will salvage what I need.   I had a couple of weeks ago picked up another Boomer complete with an OS 46 LA , Futaba 6EX, receiver, servos, batteries flight box, starter motor various bits and pieces including a gallon of fuel, all brand new for £100.  So this will now  get assembled for the weekend.  The only downside to this bargain is that the kit has been left open in a house with heavy smokers.  Some parts of the Fuz are impregnated with nicotine and I can find no way of removing it.  It has that yellow appearance and any advice would be much appreciated.  Won't matter once its up, but it would just look better   Second up was my vintage Maricado which is a 15 year old low wing model that I renovated and is a good bit sporty than the Boomer.  As with the Boomer I had adjusted the throws to very minimal and was trying some moves that are possible still beyond me.  Down she went right in the middle of a sea of yellow.  On my own, dont panic.  Kep't my eye on the spot and went to edge of field.  Put my tranny down with the aerial vertical and took a bead between it, the model and a building in the distance and then went a walking.  After about 30 minutes and on the way back, to give up, I found her.  Foam wing damaged beyond repair and some repairable damage to Fuz.  Will be able to use what is left of the wing to make a replacement although not foam as it is a model worth retaining.   I am delighted to have found the model and it re-enforces the advise of not to rush away and carry out a search in an area you think it is when some simple actions can make it so much easier.   Everything appears to happen in two's with me, lost throttle control etc, that in future I will give up after the first event.   Anyway, as I always finish with the brew of the day, I'm on Tennent's lager tonight, contemplating  more sedate flights tomorrow with my Cub and Magnatilla    Edited By Hamish McNab on 28/05/2009 22:40:47

Insulating tape.  A small tear can be easily patched.   Edit  And a small tube of superglue Edited By Hamish McNab on 27/05/2009 19:08:48

Strato   "I cannot speak Greek. It's all double Dutch to me !,"  When your model is heading to terra firma at a high rate of knots language is not a problem.   The biggest cause is not taking proper advise and going the self taught road. Get yourself a buddy box and get somebody with you that can get you out of trouble even if you cannot speak.  You will spend more time flying and gaining competence than you will fixing models in the self taught route. 

Ben  Thanks   The receiver is put down to provide a line where the model is??? and then direct a searcher hopefully to the exact point.  Failure in this would result in the transmitter being used as you suggest.   We took the transmitter with us but the wind noise removed its effect and apart from that I am hard of hearing(WHAT).   It all ended well, but the message to me is not to panic and try and establish bearings and use a logical approach.    Slightly off topic, with indulgence of moderators, I still lost numerous golf balls even although I thought I had the lie    

Eric   "I would suggest that putting the TRANSMITTER on the ground with the aerial pointing....."    ???????    Mines is Tennents, what is yours?

Our flying field is surrounded by oil seed rape which is getting taller and taller.  This weekend I experienced what not to do and what to do when a model goes down.   One of our young fliers got a dead stick and ended up with his model in the field of rape.  Instructions were shouted to him what to do, which he ignored and he set off to collect his model which he thought he new where it was.  Big mistake.  I joined in the hunt but soon realised that we were covering a vast amount of area like headless chickens.  The oil seed rape was about 4/5 foot high and in some bits quite impenetrable.  The senior members of the club, having seen it all before, let the wasted effort continue for about 1/2 hour.   We gave up and as we have a bothy gathered for lunch.   Senior member then ties down flier to pinpoint where he thought he had come down and after a good positive questioning session the general area was established.  We then went into the field and created a line with about 6 meters between us and  walked  forward to the target area.  It amazed me but  we found the model  quickly  within two minutes of searching.  The lesson I learned here is to take time to establish where the model was likely to be and then to carry out a systematic search.   The other lesson I learned concerned the instructions shouted to the young lad.  When you land in this environment do not take your eyes off the location where the model came down.  Put your receiver down on the ground with the aerial pointing directly in line at the spot where the model came down.  In this instance 35Mhz is far more accurate than this 2.4GHz stuff.  We are fortunate that we have two way radios the pilot can then direct a searcher virtually to the spot.     Forgive me if I am trying to teach a granny how to suck eggs, but I would never have thought of the simple actions that can be taken to help recover a model and hope this will help others.  I was at the field tonight, on my own, and I kept the model well high and within reach of the strip.   Last time I rambled on like this it was due to Telleys Smooth Flow, however, tonight I am on a more local brew,Tennents Lager.  I'm off to France July/August so goodness knows what I will post      

Great idea as I am at that stage with my Little Lewis (Miss Lizzy) and this will be ideal.   Just to add to this I have an adaptor that the cowl sits on which larger in diameter than the fuz.  Tried bits of balsa on the mounts and they kept falling off.  I intend to fit fuel tube spacers once I get it centralized.  Ended up putting small blocks of sponge which keeps it in place and I can adjust easily.   Thanks again
