Mosquito progress

ok so i laminatd a bunch of 9.5mm balsa strips together to create a balsa block for the nose. gonna sand it to the required rounded shape. created the wings. sanded them down last night. had to wear a respirator there was so much dust. the wifes car looks like it was sprayed a different colour in front from all the dust.
i got the motors and esc's from HobbyKing. Im considering using 8x6 and not 9x6 props for it. i think 9x6 would quite frankly rip the wings off. too much power.
cooling is a potential issue as there are no inlets for the eletric motors. sooo i was thinking of drilling holes in the firewalls just behind the spinner and then making exit holes in the form of exhaust stacks. going to use some round tubing to do that. spray it a nice greyish colour(to replicate a leaded fuel burn exhaust colour)

so i want to spray the model. but now i dont want to spend 100 hours sanding the surface to a glass smooth finish using sanding sealer etc. this is also very susceptible to hangar rash. so i thought about an alternative solution. you get very thin tissue paper sheets from cardies etc. you lay this over the bare wood. then paint sanding sealer/dope onto it. this will then stick the tissue paper to the wood and seal the wood at the same time. and an additional bonus is that the tissue paper makes it ding resistant. kinda like fibreglassing just much lighter. not as strong obviously
havnt tried it yet. will this weekend sometime.

also been thinking bout adding panel lines and scuff marks to weather the aircraft. a pristine looking fighter just doesnt look quite right.

ive been thinking about hatch doors for the wheels. i got 4 different kinds of hatch hinges from HobbyKing. now i just have to figure out how to make them open and close short of using ANOTHER servo. perhaps some sort of spring loaded system that as soon as the wheel goes into the nacelle it pushes on a lever which closes the doors. when it comes out the spring pushes on the lever and opens the door.

Eflite Nieuport 6 months later

Sooo.... 6 months ago in april or so i order a Eflite 250 nieuport kit and eflite 250 motor off ebay from a place called atomic hobbies. no problems with the transaction. they send it along. but i never get the notice to collect. so i stomp into the post office. who knows me well from myhobby shop days. and i see its arrived. but they cant find it. lo and behold the morons sent it back 5 days after it arrived.
anyway i gave it up as lost.
but this morning i get an email from atomic hobbies saying theyve got the parcel back and they would like to resend it to me. wow. wish we had service like that all the time :)

so. anyone know of a large hall in which we can fly indoor helis and planes? its lotsa fun. just battling to get hold of a hall big enough. check out this little eflite nieuport 17. it even has a replica rotary motor(the entire motor spins) as per the original. very cute. cant get it locally yet. but when the local supplier catches a wakeup maybe we can buy it. until then. import.
no unfortunately the lady holding the model doesnt come with it

Monday, October 26, 2009

well i never went out to the field this sat. but if anyone has pics send them to me and ill pop them onto the site.
i did the wings on the mossie. just gotta sand the profile into them now. lotsa sanding involved with that.
i see the hitec aurora has still not been released. #@$@#$@#

so my next thought on a nice scale project is a b-17. electric of course. i dont think a 4 engined bomber with glow engines would be the most stable aircraft in the world. especially if 2 or more motors are out.
Tony Nijhuis has a 72" 1.8m wingspan model
the nice part is that you can get the vac formed parts like the windows. cowls. gun turrets etc from him directly. so you dont have to battle your gat off trying to make them. always been the biggest hassle with scale aircraft build from scratch.
i think 4 x 400 size brushless electric motors outrunners swinging 3 bladed props would do very nicely. now the next question is...how the heck do i stuff a model that size into my Mini?

Tuesday, October 20, 2009

so does anyone know where i can get dope from? not the stuff you smoke....the stuff you put over nylon covering or tissue paper to make it stretch tight. i want to cover the mosquito in tissue. then dope it on to make the surface smooth so i can spray it. way to many compound corners to cover it.

bugger. rain came in. we sat at the field for a while. so i went home and sulked.
so, i tried out for 4 sims last night. works perfectly. realflight was a bit tricky to install but it is the best sim there. reflex xtr also comes in chinese by default. but you just click on the menus and change the language to english.


woooohoooo gonna try it on my 22" screen soon

Got my Stuff! WOOHOOO

yay! got my hk450 heli. Tig 325mm Carbon Blades and Motor from Hobbyking. just need a radio for it now

Also got my 4 in 1 simulator from helibuy its awesome. cant wait to try it out

Retracts for my Mossie


so ive got a set of robart mechanical retracts at home that will fit the diminuative size of the mossie quite nicely. But mechanical retracts are a ballache, getting the links setup, getting the servo not to bind, collapse etc etc etc

so i was browsing Hobbyking and i came across this neat little set

Micro Pneumatic Retract Landing-gear set suitable for models up to 3.5lbs.
Specifications :
Low profile 0.472in (12mm) when retracted
Frames 6061-T6 & 7075 aviation grade aluminium
Auto down if air tank is empty.
Each Retract weight : 10g / all parts 88g
Suitable for EDF & Warbirds models up to 3.5lbs
$59.94 which is NOT BAD. if you compare it to an equivalent robart pnemautic system

I would only use the main gear though on the mossie. not the nose gear obviously.

EDF Vampire


so i found another Tony Nijhuis plan. for a .25 sized Vampire. So i got to thinking that with a 64mm EDF fan it should be fairly spritely.
specs are as follows

i would put an undercart on it though.

Wingspan
1016mm / 40"
IC Engine
.15-.25ci / 2.5-4.0cc
Electric Motor
4-Max Recommended
Radio
3 Function (mini)
AUW
1134g / 40oz

SEE! It does fly



Thanks to henry for the pics!

Monday, October 12, 2009


so, i started scratching around on the weekend looking for something new to build. and as usual im looking for the weird subjects. so i got a short list of a electric canard. a ducted van vampire and a small De Havilland Mosquito. I decided on the Mossie.

Its quite small only 47" wingspan. im going to power it with 2 turnigy brushless motors. and im going to fit retracts and possible flaps as well. always wanted to build a mossie.

I cut out most of the formers last night and the pasts for the nacelles. this was before the knife rolled off my work bench and pegged into my fooot(EINA), blood snot and tranne everywhere! hahahahahahahaha

anyway. here is a pic of the model itself. its a tony nijhuis design. and came free in a 2005 edition of RCM&E

wow. the wind was howling yesterday. just a few peeps at the field. Fanie. Myself. Tony, Louie Henry and a couple of others. I had just finished repairing my autogyro. so i said what the hell i was going to try it. got it all set up. put it on the runway. powered it up and off it went. alhtough with a strange clicking noise. didnt quite figure out what it was. it struggled into the air. seemed a taf underpoweredf on the electric motor with the 11x5.5 electric prop. i think a 12x6e prop is more likely a better bet. anyway. i did one circuit. but we noticed the right hand side rotos were not spinning up as they should. which almost resulted in it spinning a few times. i managed to get it back. and lo and behold. the souce of the clicking sound was reveiled. The prop was catching the top of the rotor blades(DOH) and cutting them to pieces. i used a 9x6 on the rotary that i had on their previously. didnt realise the longer prop would hit. anyway easy to fix. and ill move the motor forward 20mm. it will also help with some of the balance issues.

Also few fanies HK450 again. nice heli.

Friday, October 9, 2009

well i see the weather is not boding well for tomorrow. but im a die hard. so ill be there with my newly electrified autogyro. cant wait!

Affordable helis(NOT the junk toys you buy from the flea market)


sooo. a while back fanie and i saw that www.hobbyking.com had a trex 450 clone called the hk450 on their site for $29.99.

sounded too good to be true. so fanie ordered one and put it together along with the suggested motor and htx900 servos and a telebee gyro. all recommended by the site. and what do you know. it flies. and it flies nicely. this could be a really good way to get into helis. I AM NOT STATING that they are BETTER than the Align helis. but they are damn close. and for the price its a good way to enter the world of heli flying.

Trex 450 parts fit it perfectly. they also make a HK500GT and HK250GT size heli. the HKT-500 heli i believe has problems. so i wouldnt go for that one. read the reviews.

Good Value For Money IC Motors

hey Boys and girls

a while ago i got to thinking about value for money Nitro(Glow) motors.
i think everyone agrees that OS max and Saito motors etc are lovely. but they are also a lovely price

soooo. using some musings i came to this conclusion
Decent value for money motors are:

ASP
Kyosho
Irvine
Super Tigre(some of them)
Thunder Tiger

anybody else have thoughts on value for money IC motors?

Scale Helis


So. im getting one of those cheapie 450 helis from hobbyking and im going to put one of these fuselages on it. gonna add a flybarless head as well.
i see www.heliartist.com also makes a unpainted version now in case you want to paint it yourself. would look nice with a nice sharks mouth up front like the P-40 Warhawk

ALSO I SEE THEY ARE BRINGING out an apache fuselage soon. wish they would make a comanche fuz.

Eflite Kits wanted

Im looking for eflite kits. anyone know where i can get? specifically the Elfite Nieuport 17 250 size

Internet Hobby Shops

Hey Fellow Flyers

As you know most(not all) south african hobby shops are a ripoff. so here are some sites which i feel offer good value for money and good service, some international. some local.

LOCAL
www.rcgear.co.za

If you guys know of other decent local shops post them here on the site for everyone to see. Dealers. Feel free to punt your stuff here as well if you like(within reason)

INTERNATIONAL
www.hobbyking.com (Fanie and i have tested the stuff from these guys. seems too cheap to be true. but so far the items have proved reliable)
www.flying-hobby.com (mainly helis)
www.infinity-hobby.com (helis, heli parts and upgrades)
www.towerhobbies.com (fairly expensive. but the discounts they give you make it worth while in some instances)

in many cases some guys at the club have dealer accounts with these dealers. so ask around. and it works out cheaper

Some of My planes




so ya. at the bottom is my A-10X turbine. havnt flown it for a year. mainly due to the runway being a wee bit too short. i plan to take the turbine out and mount it in something else with a shorter takeoff roll. then the pic of a airwolf similar to the one i had, this particular airwolf is turbine powered.....drool. then there is my little gyrace. half plane half autogyro. it was powered by an os wankel 30 at that point. before it got shot down due to inteference. motor got slightly damaged. so ive coverted it to electric power now. and of course the ME-262. Oneday itll be my masterpiece. but for now ill just sit and stare at pics of the real one.

Building the Field




so we had to move from the full size runway we were using. A nice farmer allowed us to use a nice spot of land on the edge of his property. We graded it. and put down a slurry runway ,taxiway and heli pad. we also did created a set of L shaped pits and a concrete longdrop.

I doubt if fanie wife will allow him to sit on the couch with those clothes

you can see how nice and wide the runway is. 7m wide. 102m long. just need to give it another coat of tar then itll be glass smooth!

Hi Guys

ok. so i decided to create a little unofficial website for RRF. chat here. post your pics. go wild.
