update glassed the wing with 25 grm cloth just need to do the ail and flaps,ive made the plugs for the wing pylons and flame dampers just need some more sanding prior to making the silicone moulds,also done the bomb bay doors.

Fuz now primed ready for the fitment of tailplane fin and tailcone.

ive sanded the fuz and its now got the glass on just waiting the flow coat then a final sand,ive moved onto the tailplane and fin as i want to get these items more or less done before i join them to the fuz, the fullsize is ply covered followed by doped fabric you can see the ribs and spar thru the covering bit like a starved horse appearance but not as severe,to obtain the illusion i first masked the area out then sprayed with undercoat removed the tape and rubbed down followed by another overcoat of primer and sanded backwhich leaves a very slight impression when sprayed in colour should give the desired effect.

started to sand the planking much the same as the full size.glass cloth covering 48 grm for the wing seat area and front and 25 grm aft of the wing

Done the machine guns and cannons another job ticked off.

HI Chris yes it has sprung oleos but they are a bit stiffer than i would do normally due to the fact there are 2 working in tandem if they were too soft i think the wheel might wander under load,ive got a single jeti 6200 radio battery in the nose reason being ive got 10 servos plus the retract actuators altho i may decide to run these off a seperate 2s battery the escs along with the 2 4s 6250 lipos in the nacelles as far forward as i can get them may go to 5s at a later date when i get round to testing

sorry last post has gone pear shaped big time ile re do it later

Hi chris cg has always been in my thoughts the radio is all in the bomb bay which is part of the wing the servos are all at the front with the receiver and switch just behind the only part not in the wing is the battery which sits in the machine gun bay at the front ime using the jeti 6200 power lon battery which is fairly heavy,dont know if i will have to put ballast in hope not wont know till iput it on the scales prior to flight. regarding the u/c it follows the geometry the same as only ive made mine from ali tube the ends are machined plugs which are glued and pinned in the tube and have either a slot or tongue machined in them there is a down lock where the arms break which is an over centre joint which locks the u/ down the actuator does the up lock. the legs are normal looking that i made with a machined bracket

Regarding the tyres, firstly a master is req this is turned from mdf and the treads are thick paper cut on a cutter to the correct design then given coats of sanding sealer sanded and painted,next a mould has to be made out of silicon this is made in a hinged box with clips on,the polyurethane foam is mixed and poured into both half of the mould then its clamped shut,you have to be quick because it starts to rise in about 40 seconds, i found after a few not very good trials that it was better to do in a warm room ,i did mine in the conservatory in summer and it was hot! leave for 30 then open mould i should say i dusted talc powder in the mould before pouring to aid removal,all thats left is trim and mount on a wheel i made mine from 2 1/4 ply discs with a sandwich of chemiwood to stop the tyre deforming when the two halves are screwed together could have made them from ali but didnt want the weight. originally i got 2 lazer 155s and they did go in the cowl with a prop extension by moving the bulkhead,i did make a custom fuel tank but didnt have enough room at the rear of the engine once the carb was on,there was no way round it maybe if i would have done a pr16 there wudnt have been a problem any how converted to electric 2x axi 5333 motors 8s 6250 batterys and hobbywing 100 amp controller.

1/5 p51 enlarged 25% from the bt plan powered by kolmn 50 4 stroke all balsa and ply as per bt design but with some mods to structure ,ive been waiting to maiden it for the last few months,it has modified robart retracts converted to electric and home made oleos.

u/c nearly done just req some more work on the door guards the axle cover will be fitted when final assembly occurs,next to receive attention were the moulds for the cowls and canopy,forgot to mention its a scaled up bt design with a 100"span giving it a scale of6.5:1,once i got the difficult bits done moved onto the airframe.fuz was done first with lots of planking built in 2 half shells then joined much like the full size the tailcone is a glass moulding unlike brians which is balsa,great care was took to build the tailplane and fin as light as possible due to cg concerns,wing is conventional construction with the addition of the nacelles.

started a build on a mossi so will show progress up to date,first i built the uc if i couldnt get this right it wasnt worth doing it because its such a big part of the character took prob about 2 months to complete hopefully the pictures tell the story also cast my own tyres which have a dia of 6.5 inch they are operated by a screw jack affair which i made.
