I tried out the 3d printed chase cam today. Came out very good but i will need to adjust the length of the rope and the angle of the gopro. The flight is very stable and the petg makes this design quite sturdy and affordable ( less than 10$). You can find the files here :https://www.thingiverse.com/thing:3427201

My first real engine out was pretty uneventful

Working towards improving my kiting skills. Filming myself helps to see what i'm doing wrong. Here at the end i brake the opposite side. the collapse was recoverable. Winds were 20-25kmh. I was recovering collapses later that day but i wasn't in frame sadly. I will continue to kite regularly as it seems to help my launches alot.

i have just moved from a ros125 to a moster classic. the ros 125 was much smoother than the moster  at mid range rpm.

I believe it's just the way the engines are built. Maybe look for a counter balanced engine. it will be heavier but smoother 

looking online it looks like it could be a bad carb adjustment too

Maiden flight!  It's awesome! 600 feet per minute trimmed out 1/3  is incredible.

Video is up! 

it really was ! one squirt with the bulb then bam fired right up

Parts arrived Friday so here's the reassembly. I left out some parts as it was the same as the dissassembly. I set the squish to 1.5mm using my thinest gasket and use loctite on pretty much every bolt.

Cleaned crank halves 

Heating crank halves to 220F

New Bearings for the crank

The bearings dropped right in (shown in video. Now putting the new crankshaft in.

Closed the crank halves. used permatex ultragrey to seal them. Torqued to 10 Nm and used loctite.

Installed carter support and crank back on the frame for easier reassembly. Carter support sealed with permatex ultra grey and torqued to 10nm with loctite. Seals pressed in (shown in video)

à

Installed flywheel, pinion pulley and big pulley. I replaced big pulley bearings following scout aviation tutorial. Flywheel torqued to 40nm

Carburetor  and reed valve back on.  Torqued reed valve to 10nm and carburetor not torqued only loctite .

Redid the whole fuel system with the custom primer bulb and blow tube

Work area in my parents basement

Reinstalled muffler,silencer and airbox

Installed prop and gave the engine its first pull, started right up.

Might get the parts next week. they ordered a crankshaft last week they had just changed one on another machine.

started to clean up the frame and redo the fuel lines. checked the carb and it looks like it was overhauled recently. I will reset the carb to factory settings because it was obviously not running right.

Throwback from this summer. That's why you don't stop running hehe

Not sure why but it seems that people are now buying gear based on the hype around it instead of actual quality and value

Part 1 is up

Its best to "inch" your way into getting bigger, that way if there are any errors you will likely only lose a wing tip.

 

indeed, only once so far i felt like my lines were close to being slack... but i don't know maybe its just that my wing is solid, i haven't even took a collapse yet. better not going into that territory. i must say i'm at 115kg on a 120kg max glider so that must help

engine  a bit dirty, exhaust welded twice 

broken end of crankshaft

Piston is melted, needs replacement

Thankfully cylinder is in good shape, very smooth

removed carb and airbox

Removed engine from frame and detached carter support. Then split the case

Finally removed the big pulley, i will replace the bearings

So far everything is good exept for the crankshaft and piston. I will replace all seals and bearings. I will use permatex ultra grey to seal the case back together. 

Will post videos eventually

picked up the engine yesterday. Teared it down today so now i am waiting on parts. Overall it's in better shape than anticipated. i think the previous owner heated the crankshaft  to pull the starter pulley assembly (not needed) which caused the faillure.

main features

2x new Carabiners

Apco universal seat in good shape 

15 liter gas tank 

solid double hoop frame 

3  pull starter assembly

brand new cylinder head 

gaskets for carb, exhaust and cylinder head

brand  new carbon prop 130cm and wood prop 125cm

pictures will follow

This summer i started doing small wingover. Concentrating on feeling the wing and getting muscle memory to keep some pressure on the outside. as some have stated i could go deeper in the brakes but i am not ready to go over the top yet. Just feeling everything out right now. The video is my third set of wingover ever so it's normal they are not good.

Launches are still getting better. 115 flights done so far confidence is growing but i gotta be carefull not to become complacent.

Will soon  rebuild a moster 185... it should give me the ability to do more wingover  with the better climb rate.

Some images and a writeup of you rebuild adventure would be cool.
Popular engine like that... It would be nice to get a closer look at its guts  

okay i will do that! Definitely will be a learning experience for me and probably others

Bought the engine after speaking with my instructor friend and Eric Sigier from AirProParamoteur.

My guess is that the rings and piston are good, the magnetic flywheel broke off so that would explain the drop in rpm. I'll start by tearing it down then just changing crankcase bearings, seals and crankshaft. Parts are in stock here

Anyone has experience with the moster 185 classic? 

Local guy is selling one with broken crankshaft very cheap. I'm trying to determine if it's worth fixing with around 800$ of parts or buying a moster silent for 4000$ and swapping it. The ask price is 1500 with sd2 frame, two propellers, seat, new cylinder head and few other parts. He says the engine has 120 hours and the pull starter rope wrapped around the flywheel and broke the crank shaft for some reason. He came down with reduced rpm and landed safely.

do propellers fits on new moster's?

is the mount pattern the same as the new moster's?

Is reliability an issue with old moster's?

i am currently flying a sd1 frame with a ros 125 which i quite like but lacks power. maybe the rings are done on my ros 125 i will be checking compression when i receive my tester.

Are you UK based?

I loved the frame...get in touch with your local dealer first though and make sure you're happy with how responsive they are and their availability of parts.
I got rid of mine in the end and changed brand. As much as I liked it, the ease of getting parts or getting hold of the dealer put me off the brand completely.

There is no dealer in Canada  and so far they responded to my email (though there is 6 hours difference between Italy and Montreal).

Maybe i could only buy the engine and install it on a kangook frame.

I'll see ...

Looking to buy the new sky 150. The price is very reasonable for direct import to Canada. Would want to hear some who flew these frames with the sky 1.1s . How's the quality? Are they good frames?

I notice you have both A and A' in your hand for launch. Try just having the A (the centre A lines) in you hand,the launch should be easier.

Split A's were developed for this reason.

I have tried both methods and prefer taking both, i have the impression that it gives me more feel but the difference is slim to none on this wing. What i have found works the best is to trim out 25% so the wing comes up faster and more easily.

 I am quite pleased with my takeoffs recently, i am progressing well.

First flight( well i did 5 launches in a row trying to adjust the seat). I like the high moving bar but i realised the seat is probably too small... it's a Large compared to my miniplane XL. So i decided to put the miniplane seat on the frame. As the saying goes '' the simpler the better'' and that is totally right with 5-6 adjustements instead of 12! Though i must admit it was easier to run with the apco seat.

This frame will suit me fine until i get my hands on a pap tinox low hangpoint.

flight #79 and #80

Saw a plane very close to me around 400-500' below my feet! definetly spooked me.

My landings are getting better now letting out 1/4 trim on my itv billy. I maybe should try making a 90 degree turn before landing to give it some energy. I should practice it when there at no people nearby tough

 i am also babystepping towards wingover, feeling the outside brake as i go at it

If you haven't already please replace those damaged lines, even if you suspect it is only the sheathing that is damaged.

i will as soon as i have the time to
