hi there, new to the forum. I'm after a 7 port. 21 go marine engine. I don't know if I'm late to the party, but can't seem to find a supplier that stocks them anywhere! I'm from the UK. I've contacted go through their Facebook page and their online contacts page on the website. I've even messaged the Europe distributor but nothing but radio silence! have they folded?

Any particular reason you're after that specific brand of engine?

I've heard good things about them and after blowing con road and totalling my previous engine I'm after something to have a play with and cheap. I've since bought an x-act .21 3 port motor which I plan to do a bit of work on. £65 for a high revving motor seems fairly promising. I will be saving up for a cmb. thanks for the reply. if anyone has any missing tips to try and squeeze a few more revs out of the motor would be gratefully received. currently running a Macs 1329 tuned pipe. is it worth taking a dremmel to the ports? cheers Olly

Degree the timing of the cylinder ports and crank port, measure the size of the carb throat, and measure the bore of the carburetor. With those numbers I could give you an idea of where to start.
If you're going to modify an engine, leave the Dremel put away except for the crank. For the liner and piston it's best to use diamond files and do it by hand. Rarely does it require much work to get a few extra degrees of timing.

ok great, I will take some measurements when I get the chance. thank you. 😁

unless your pretty clued up on how to exactly modify timings with port shapes etc etc on a glow engine your better off leaving it alone and just play with head clearance and high nitro plus a good tuned pipe with correct length. same goes for crankshaft intake work , dremmel out too much and bang goes the shaft at rpm,s.

Most of the limiting factors in how a glow plug engine performs has a lot to do with the crankshaft alone.

thanks for the advice crapshooter. unfortunately I'm limited to 25% nitro in the UK as the government has deemed it as an explosive. I can buy a licence (£40) but still only upto 30%. I've got a Macs 1329 tuned pipe that I'm going to run. was going to start off with a length of 250mm from the centre of the glow plug to the widest part of the pipe and go from there. Olly

Thats some weird rule your govt has on Nitro amounts to be used, you guys certainly won,t be breaking any speed records with 25% nitro in 21 size glow engines [ sneek in 50 to 60% ] ha ha. What about Lipo Batteries ? more chance of a lipo exploding than a tank of high nitro content.

Brexit doesn't have anything to do with the limit on the nitro as it's been that way for a long time. A lot of Europe runs on what we think is low percentage nitro, some even nitro-free. It's really expensive there also.
The Go-Engines (there is also Go Engines, no hyphen) are basically clones of other marine engines. Anyone remember the short-lived CS which were OS splashes but with really bad quality? Even their logo was stolen from OS.

think i still have one of those cs marine engines sitting around somewhere. they were a side exhaust , all silver alloy just like the first model o.s. engines like the FP / model etc. so it looks like you guys have no top fuel drag cars racing there as they run 100% pure nitro.

100% ----90% big deal. the nitro content is still way above what is allowed for r/c models in the u.k..
Incorrect. NHRA limits top fuel cars to 90% nitromethane. And they do have top fuel racing in the UK.

Like I said, you need to get out more - and try to make accurate statements in the forum. Wouldn't want you to lose any cred.....

Sorry Crapshooter, he's right. The NHRA dropped the maximum amount of nitro the fuel classes can use years ago.

so what am i supposed to do go to the drags ? my point in this conversation was regarding the very low nitro fuel percentages allowed for model r/c use , this is why i mentioned drag cars can run 100% even though its 90% wasn,t a bad guess from myself i might add. i am not giving false info unless were talking drag cars which where not are we. so why 25% nitro maximum for r/c use and 90% nitro for race car use ???
