Hi   I bought one of these from GiantCod and it work great of my depron Extra, or it did!  Gravity 1 aerial 0.    My aerial has come off but I can't really see where its meant to go I wondered if anyone has one and can give me some idea.  I have a friend you's pretty good witha soldering iron.   Anyway if you want a look at my extra its at www.keith-howlette.co.uk   Thanks

1. Vicker SuperVC10  for EDF very rarely modelled.  Trying myself 2. Lockheed Super Constellation 3. Avro Vulcan  

I've just be christened by a propellor on my pinky, ouch it hurt. Stupid boy,!! A new plane would sure cheer me up. Keith (aka fingers)

Thanks for all you comments, I think perhap I didn't explain the issues very cleary. I suspect the CofG is wrong on the model and using the contraption is suposed to locate where the Cof G is.  When I know where the Cof G is then I use my normal balancer.  I 've also in the past purchased models without any plans/intstruction(e.g. Ebay) and its a bit hit and miss getting the Cof G right.  On a straight wing such as trainer its fairly easy to get even calucalating it with some of those freely availble tools on the net.  But for something like a spitfire with and ellepitical wing its not so easy.  My dilema is that using the contrapion I get a CoG around 55mm from the LE where the plan indicates 30-35mm.  At 35mm I need to add at least 3 ounces of lead, which on a depron model of 24" wingspan is quite a lot of extra weight.  At 55mm CoG I don't need to add any weight.   Thanks Keith

Hi I came across this some time ago and wonder if it does the job. http://www.utahvalleyaeromodelers.com/framer.html?url=/articles/glitch/09_2003/glitch_sept_2003.pdf Its on page 5. I've built one and it seems to get it right on my other models but I'm a bit unsure. I have a Green Air Design spitfire and that I just built and when I put in on normal multiplex C of G tool with the C of G at the recommend setting of 35mm from L.E its very tail heavy. Putting on the contraption it seems to point to a C of G arounfd55mm. To get it right on the recommendations I'd need to add some lead. I can't shift the battery its right up as far as it will go. Any thoughts Keith

Thanks guys.

Hi Anyone know what the inlet and exhaust value clearance should be on a SC52 four stroke.  I've just fitted a new cylinder head.  I did measure them before iItook the old one off and I think its .010" on the inlet and .012" on the exhaust.  Not sure what that is in metric, but either will do if you have it. Thanks keith 

May be I'll be lucky this time.

Hope I'm lucky this time

I'd love to win, never won anything

I'll give it a good home and promise not to crash it. !!!!!!!

Hi I'm thinking of buying one of Just Engines motors,  the JEN 47.  Are they any good, all the right ups seem good .  Keith

I'd like to win anything that flies, well maybe not a bat ehh!!

Thanks Bruce, thats exactly what I wanted, cheers Keith 

Hi I'm off to Boston and New York in April. anyone know of any good model shops over there. Thanks

Hi  I have a Priory Models Lanc which I fly on 8 and 10 cell Ni-Cad about 2000mAH.  I'd like to try Lipo's but don't really wan to go brushless just yet with it as it already has the motors glued in 4 x 400.  I 'dlike to try Lipo's because of the weight saving for equivalent capacity.  I have a 50 amp Speed Controller from Overlander but I don't think its Lipo compatible.  I've heard that if you drain too much voltage from a Lipo it can damage it permanently.  I think there is some device you can use to cut the power but I not sure.  I use a separate receiver battery.  Can anyone recommend anything. Thanks

Hi I'm attempting to build a EDF airliner, a SuperVC10. It will mainly a foam model of probalby about 50-60" wingspan. I'm reading 2 books on aerodymanics for models and I still can't work out what I need. My question is if my model weighs 6 pounds for example do I need 6 pounds of thrust. I want it to fly in a scale like manner so I won't be performing wild and crazy manevours, (if I could!). Is ther a rule of thumb say for 6 pound model you need 3 pounds of thrust. I'll probably use 4 GWS 55mm EDF units with brushless and Lipo's Thanks for any advice keith
