Electric to Four stroke glow !
« on: July 28, 2018, 09:45:14 AM »
Hi Guys.
There seems to be a growing trend in our club to convert electric artf's to IC power, one member has fitted an OS 40 Surpass in the 80% size wooden Wot 4, goes very well !

My contribution is a Mini Ultra Stick with a Saito FA 30 SH, have already flown it with an SC30FS but decided on the upgrade to Saito power !

Are we just a bit nuts or do other people find electric just has no soul ?

I'm converting to electric only, simply because it means I don't have to hump fuel, flight box, starters etc. out to the car, from the car to the pit area, back to the car then back to the shed.  All this saved effort leaves me more energy for flying and these days I have to ration my energy out through the day.
Less soul?  Yes, but then they do need a different skill set to get the best out of them so there is still a level of challenge in flying them.  I do still miss getting my hands dirty but I don't miss the mess and occasional utter frustration when an engine won't play ball.

How tricky is it to stiffen up the front end of an ARTF?

Well to achieve the CG I chopped about 4 inches of the front off and made a ply firewall, so the original mounting no longer exists!!

That would help!

How do you feel about the drop of in power and hence performance  :ev

Models designed originally for electric power are built much lighter. I don't know how long they will last structurally with a satanic vibrator on the front and fuel seeping in.

Hahah ! With The Saito 30 I am seeing 10600rpm on a 10x6 prop, just over .5hp or in elctricery terms about 400 watts.

The AUW is 1lb 14oz which is 2oz more than the 3s 2200 setup, static thrust on IC is 3.37lbs, so It should have enough poke !

 I convert electric model to IC, as they sound better, :co
 not just weeee as it goes past, :embarassed:

No taking the plane apart to change the battery
No 100€ battery's that loose 50% of their energy in a few flights
No waiting 1+ hour for a 3 minute flight
No changing the plugs on all of the wires because hk or some other company has changer theirs
No expensive chargers to invest in
No opening up the bonnet and taking apart the battery box to get to the car battery
No pushing the car to start after charging 4 battery's which have flattened it for 4 x  3 minutes flights
No ammunition box blowing up in my face or setting light to my garage ( already been their )
 Last but not least the excitement when the engine starts in a cloud of smoke, that's REAL FUN ! :nananana:

 Ok I will stop their,,,  :''

Well said Paul ! Glad to see a fellow glow head join in.

Have the same power when the tank is only quarter full
Have that instant connection with the throttle particularly with engine braking.

LeckyBB......"satanic vibrator" Love it ;D

You really need a Saito 82 for that, do they vibrate or what, loads of power but a bout of RSSI when you touch the needle.  :D

Battery hatch
Buy decent batteries instead of expensive ones
Charge enough up the night before - or with a quad charger charge them while you eat breakfast
5 minutes to swap a connector - takes longer than that to clean the goo off  before packing your glow model away
No expensive starter/pump/glowdrive etc
again, charge at home the night before
buy a decent car
no glow fuel or petrol storage problem - can't say about your lipo storage procedures that lead to immolation
That last one - no argument.

As I said, health issues leave me no choice.  I have nothing against ic engines, I used them myself for over 50 years from little DC diesels and Cox glows through to medium size petrol but the time has come to take the easy route if I want to get more than one flight in a day.
By the way, you forgot about 'live but static motors ready to chop your shins at the careless flick of a stick' and 'expensive esc and telemetry in addition to a receiver battery'.  Sure, there are drawbacks but the ones you list are  mainly just a half-hearted approach to a different power source.
Anyway, back to the storyline:
A mate was more than happy putting 4 stroke motors in Sebart models, mainly it involved some ply cladding around the motor box.  The results went very well.

 Wow I am getting all excited even thinking about the Saito running    ^-^
6 (? ) of them and another half a dozen 4 strokes you can't beat them. I have around .

One IMPORTANT thing I missed was safety, ok who hasn't been bitten by a prop when touching the needle valve  :ev

 But leccies are even worse I have seen some really bad  accidents when those electrons go haywire, starting with chopped fingers.

 Back to the subject,  :co usually they only need corners reinforced with some samba glued in with epoxy  and some fuel proofing in the nose, and a doubled up firewall with some DECENT plywood.

I have a couple of foam leccies and a converted balsa slope soarer but they are for the times when it's impracticable to fly my petrol powered models. I gave up on glow many years ago.

If we’d have had today’s high performing electric powertrains 40 years ago we’d now have a ton more flying sites closer to population centres.   And so, maybe, a lot more people taking up the hobby?
