Default Classic 1977 AMPS SX100 F1 build

I picked this retro F1 hull up,originally designed for inboard nitro with steerable drive,im told this could be the last remaining 1 so i feel very lucky to have it,gonna go pick up an new driver and plastic for the screen to finish the scale look and OB cowl
Iv decided to install a 7.5 ASP nitro engine (originally for the cat) and put it together but will have to use strut and rudder set up instead but thats no probs
will need to self mod the exhaust to fit and make some engine mounts but have everything here to do that only need to order some stuff which i can do this week could possibly have it built and ready to run by the following weekend
More modern looking was made for it but i prefer the retro look for it i think

Maybe I can find you a 'lenkstrut' from WD200. [link=http://www.wd200-modellbau.de/?Antriebe%2FDrives:Lenkstrut]L I N K [/link]

Or I can rebuild a K&B leg ... and I have an address for OB-cowls too.

Thanks Hendrick
the Lenkstrut looks ok
as for the K&B and OB cowl sounds good idea too
Hmmmm

as it is at the minute the setup is may require me to use the newer canopy for clearance so i might do some mods on it and trim it so it fits better
ill post some pics soon

Had a day to myself today while the workman in doing repairs hehe
Iv trimmed the canopy for better fitment and managed to lower it 1/2" so looks abit sleaker,got to use the modern canopy for now due to clearance issues 
Iv mounted the,strut & rudder and installed the cowl locks 
Next was to make up some engine mounts and risers to install it into the hull and also modded the exhaust manifold to get it to fit quite alot done in all 
Just waiting for deliveries over the next couple of days of radio box,fuel tank etc 
post more soon

That motormount is not one of your smartest idea's ;-)

Almost all engines 'sit' on the mount , and not hanging underneath it.

Would not surprise me if there are nuts used , instead of treaded into the mount.

So in short ... in no way a 'quick-release' type :-)

And if you want a real tuned-exhaust instead of that 'muffler' ,

I have a OPS .45/7,5 lying around.

Nice find Daz!! I would take up Hendrick on that offer of the pipe-it will smoke your current one for sure. You probably will find that changing the mount will save you some cursing down the track too. The nitros vibrate so much more than gas and they will find any slightly loose screws or nuts no worries. I watched one ob shake anything it could off the engine Sunday, even off shook itself of the lower. I dont think it wanted to get wet as it was pretty chilly and it won that battle.lol
Maybe you could replace the angle al on your mount for some square bar and drill and tap the mount holes and mount from the top so you can get the engine out easier for inspections and repairs. So are you going cmb for the cat now???mmmmmm.
All the best,
Dion.

Hey Hendrick
I did the mount like this to keep the rubbers in line with crank.read that its best this way and helps reduce the vibration from the engine
I have used nylock nuts under neath and will add some thread lock aswell ,the mounts on the engine are not threaded so did it this way instead
Im waiting for new rubbers with male + female threads so it will be easier to remove from the risers/hull
as for the exhaust,they did send the wrong 1,im waiting for them to sort it out now (not having much luck with exhausts at the minute LOL) thanks but my funds are on the limit now and still gotta order and sort the starting gear yet and some fuel + had to order some other stuff aswell to complete the build

Hey F1
Its a cool find for sure
understand what you saying about the exhaust but funds are running low now as iv spent a fortune over the last few weeks
As for the cat not 100% on what to throw in it,the CMB offered is 15cc the cat is only 38" so will be too much for it,but if i can sort the funds soon might have another idea for it instead hehe
Still alot to do and learn but ill get there soon and really busy at mo with new job aswell
But more than anything this is just a fun build and chance to learn the nitro route haha,also my boys will probably use it to learn to drive the F1's ready for next yr
More updates soon

Not sure how good the bearings are in those engines as I know nothing about them, but when you change them, change them to some swiss bearings. Best to do them before they do you!! Usually its the rear one that goes bad first. Stay away from any metal retainer bearings.
Might think of swapping that cable collet too!

Strange part about that .... I can buy the Swiss WIB bearings cheaper in Canada ,

as in where-ever in Europe. :-(

The engines ASP are used over here in the BMPRS racing and they are pretty,1 guy been racing the same engine for the last 18mths without any problems so thats why i thought id try 1 so will let you know once running
Sounds like a plan bud be good to see them together against each other LOL

Looking good Daz! Just curious about how the engine mount will work. Did you tap the angle aluminium as it will be tricky to get a tool under there if you still plan on using nylock nuts. The engine on top is better than underneath how it was. Your kids must really love you mate!! Great stuff!!
All the best,
Dion.

Hey F1

Im waiting for some new mounts male 1 end then female other end this will allow easy removal of the engine

bit more done 
arranged and fixed the servo mounts in and lipo placement,also installing the stuffing tube
Just gotta sort out now best way to secure radio box,also waiting on male/female rubber mounts to allow easier removal of engine should i need to
and trying to figure best way to mount the fuel tank aswell but not far off now
Tomorrow i will add a layer of carbon fibre and resin in the stuffing tube properly aswell add some floatation in the sponsons,got to add something to the front of cowl to lock it down so still a fair bit to do yet but going together well so far
