Bergen R/C Helicopters > Description of all the G23, RC230-231, G-26

Can someone please give me a really good definitive description of all the motors available out there in the gasser department. I have heard all kinds of numbers being thrown out and everyone seems confused, even the experts.

G-23
G-26
RC230
RC231
B.H.Hanson
Bloise Engines
others?

I know the difference between the G-23 and G-26, but I would like to know what is equivilant here, are some the same engine with different names? I know they all fit the same mounts for the most part. Which are better? best? HP rating? etc.

Can someone give the final say on all these engines in a nice description?

I have heard of g231 puh, g231RC, both being used in heli's is a 231puh the same as 231rc or different.

Let me ask this. of all these engines, which would people rather use. Which gives the most power and torque of them all???

Interesting... thanks for the information.

I thought I heard of people running the 230RC's in helicopters? Bergens and X-Cells? could be wrong, maybe it was vario...

Tom,
Very good explanation!!

Some of the confusion about the G230RC engines may be my fault. Just over a year and a half ago, we put a cylinder head and piston from a G230RC engine on a G23 crankcase. We matched the porting, and filled in the two cylinder mount holes that were not used.

I then ran this engine all year, showing the increase in power available and let people know that this was a G230RC engine. I did sell a few of these, but with the advent of the G231 and G26, it's easier to go with the stock engines.

There is a hop up kit, that turns a G23 motor into a G26. But here again confusion may reign as it is called a 260RC hop up. And the kit only fits certain 23's.(disclaimer)(I'm not sure right this moment which one it is, so I wont try to cause more confusion)

As far as I know there is no G260RC engine, so I'm not sure why they chose to go with the "RC" designation.

I'm not entirely sure the G230RC is more powerful than the G26. At least in my case with the highly modified G230RC engine.

I think my father and Tom are the only ones able to keep all these engine designations straight.

Josh,
To make things a bit clearer here, the 230 RC engine's crank case is fairly large and heavy with a cooling fan and pull starter built in. This is why they will only fit in a heli built to carry them and why Chris did the modification to his and confused the croud .

I would have to agree with Chris on the power issue. I think the G 26 PU developes more power than the 230 RC at comparable RPMs. The way they get some of the high horse power ratings with these motors is to operate them at ungodly RPMs. Most of the time this isn't practicle with our flying machines. The vibrations become to much and the cooling system gets big and heavy. So I would have to go with displacement over RPM.

Glad to here this information... Yes I was confused and Yes, you have cleared most of that up for me.

So now the question is to how the modified group goes with the stock, group. How do Blois and Hanson motors compare with the G23 and G26 engines?

For example the G23 that hanson and the head for the G23 that blois have made in the past. How well do these modified G23's work agains say a new G26? I know my Hanson motor has the same size piston as the G23, so it must be porting and balancing modifications and I think they rate at around 3.3 HP.

Thanks chris fidman and malorie.

I have not been keeping up with the modified engines. I have a Hanson modified G23 on my Observer. That motor is a stock G23 that has had the ports enlarged and re-timed (as far as I know). I would imagine they are doing that sort of thing with the new engines also.

I called B. Hanson last week and he quoted me @ 5hp on his new 231 modded engine

Yep, he said the peak torque curve comes in from 8500 to 11,500 with peak hp at 11,200 however these figures are with his tuned pipe, gonna be lower by 6 - 800 rpm and .5 hp with a Bergen pipe - (his best guess, no dyno data with Bergen pipe)

Doh! - you got me! I was going off memory so I gut out my notes and it says "Optimum HP range - 9 -11,200" "Tourqe Curve 8800 - 10,200" "Peak HP at 11,500" Then there are some other notes about the factory reccomended rpm and his max rpm after his mods(16,000) but I don't see a need to spin it near that high unless the gear ratio's require it??? After considering the options I think I'm gonna take the 231 that comes with the heli and send it to him before I ever run it and have him work it over - $125 and he keeps the original jug and he will knock $20 off the pipe if you do it all at the same time.

I need to call them to, but do you know if they will take the original hanson g23 and modify it? I know he was saying around 150 a while ago for a modification, but I can't remember if it was to make it a G26 or a 231, or if that is even possible. Anybody know? will they touch an engine after it has been run like mine?

I'm pretty sure he will, when I was talking to him he asked if the motor would be new or run, I think it will be more due to needing to change out the Jug??

Blois cylinder works well.

For what its worth I recently installed a Blois cylinder, WT-603 carb and a Bergen pipe on a stock G23-PUH in a Bergen Observer. I don't have any data but WOW!!!! what a difference.

I originally wanted to run the X-Cell type exhaust as I had heard there were problems with the Bergen one. However, there was no way I could see to make it fit the Observer with out shorting the header which I heard burns out couplers too fast. So, I went with the Bergen and so far... no problems. Sounds cool.

With all the "Stuff" added they are wanting me to fly around the Observer is at around 24lbs. There were times with the stock motor that I didn't think it was going to stay in the air. Can you say "Miiiillllllk the landings". There was almost NO power to arrest any decent.

Now its a no brainer. It flies just like it did with the stock engine and unloaded up.

How can you tell it's a WT-603 carb, is there a P/N somewhere?

hey everyone, I am a goped enthusiast. we 'pedders use G230RC's a lot, cause its got 2.5 HP stock over the G2D's 2.0 hp , and the G23LH's 1.2 hp. when highly modified, some ORC's cause push out well over 7 hp at 14,000 rpm - 20,000 rpm, you just have to know what you are doing. personally, I run a LH/ORC hybrid motor ( G23LH case's, and crank with a G230RC topend), with ported cases to increase fuel transfer to the transfer ports, creating more torque off idle, and more peak RPM and H.P. my ped has been dyno'd at 3.9 HP at the rear wheel @ 13,900 rpm. well, try checking out some threads @ www.gopednation.com, if you stuck a motor like most pedders run onto one of your planes, who knows what it would do. well, just thought I would post. peace out!

ok. a g23 is a normal motor. the g23rc is the racing/high performance version of it. a g26 has the same crankcase as the 23, just a bigger head and pistion. i have a racing goped, it has a g26rc.....tuned pipe, k and n airfilter racing carb, racing spindle, cooling scoops, aluminum deck lots of fun.
