Thanks I'm debating buying the fastrax or going for a new drill as i need one around the house anyway!

Hi there, Just after some advice on buying a roto start, I've used pull starts for a while on my 7 without any issues but my ST came with a backplate for a roto start which i have now tried using a friends drill after my new pull start broke and it seems like a good option. what roto starts do you recommend or should i just buy the rod and use my drill? Any advice appreciated[emoji3]

Hi there, Just after some advice on maintenance, I'm gradually learning and at the moment i clean the buggy with a damp cloth and a little wd40, then give it a coating of GT85 other than brakes and clutch. Finally put a few drops of after run oil in the engine. Then every now and then wash the air filter sponge and re-oil. Now just after some advice on other bits i should be doing, do i need to grease bearings and how often? Also when to change oil in diffs and shocks? Any other bits? Thanks

The backplate was standard so it was a different one way bearing and axle, so ordered a hex axle from Marderboy and will try that first and then may have to get a new one way bearing. Do you know if i should clean or lube the old one way bearing before fitting a new axle and what should you use? Thanks

Took the roto start off and underneath it is a different shape to that on the Mach 28 pull start I have, does that mean the last owner changed the back of the engine?

That's great thanks I'll have a look then

Hi there, Just got a cheap 2nd hand hyper st and it has a roto start but want to swap this to a pull start. Do I only need a new pull start as on modelsport for

Hi there, Needed a new plastic servo horn for my savox 0254 on my hyper 7 so ordered some of ebay size 25t suits futaba. now ive got them they will not go on!! been told to stick with plastic as they protect the servo more, is that right or aluminum ok? Either way can you recommend a servo horn that will fit my savox 0254? Thanks

ok thanks

thanks, where do you ideally want torque and speed servos?

Hi there, Right currently have a hobao h101 servo on throttle and savox 0254 on steering but after thinking i may have damaged one (luckily i haven't it was just the horn) want to order a couple of spares. So what are good replacements for up to

just noticed your post, i was thinking of just making the hole bigger/higher in the splash guard so it may lift a little more, bit of a rubbish design on their part.

Hi there, After a decent look over my buggy i can see that the rear brake linkage clashes wth the bottom of the air filter. This is when screwed to the splash guard as they designed. Just wondered what everyone else was doing to get over this?

It seems to be the teeth in the plastic horn that have gone rather than servo so much better for my pocket![emoji3]

Haven't tried it moving since so I'll see if i can test tonight, steering trim is fine as i set it to neutral. one way it goes back to straight and the other way goes back past that point.

Hi there, had an issue with my steering, it was steering ok but then when turning it started going back further than straight. ive taken the steering horn off and the servo seems fine without so put the horn back on with the wheels straight and in neutral trim. also turned the st dr down a bit below 100%. Now the car steers fine when i hold it off the ground but when i put it on the ground it will hardly turn but also doesn't back to straight. does it sound like the servos knackered or something else? new to this but gradually getting there a problem at a time![emoji1]

i had overtightened the screws the linkage slides through and have now taken the whole thing of the servo and started from scratch with the trim in neutral . moved in the grub screws a bit and the brakes seem ok rolling it and with a bit more power through the rear![emoji106]

that does make the brake work but the i'm left with a big opening in the carb, i guess i need to play with adjusting all linkages.

My hyper 7 seems to apply brake when i take my finger of the throttle is that normal, rolling the car without the engine on it doesnt have any resistance when i have the throttle applied but when i take my finger off the throttle i can feel some resistance from the brakes. But the servo doesnt then move any further when i actually apply the brakes so no more added stopping power. However if i pull the brake linkage it does apply more so they are physically able too. Any help appreciated [emoji1]

Thanks just ordered the hpi after run oil and air filter oil, will give it a couple of drops after each run.

Hi there, Recently got a hyper 7 tq2 .28 and was just after general maintenance advice, what does everyone do? Is it just a case of cleaning it and checking for loose parts after each run, how often do i need to put after run in the engine? only just found this stuff and assume the hpi after run is ok from modelsport? Any help appreciated as I'm new to nitro![emoji1] thanks

Thanks for your help they are both ideal, may go with the cork then add the stopper when i next order from modelsport. I'm new so have only tried the exhaust option.

Hi there, After running out of fuel and trying to prime my hyper 7 with the finger over exhaust method, is there a stopper or plug available that people use when its too hot to touch? Can't seem to see one. Thanks

Been looking at these and the kyosho multi spike, both around the same price. thinking the nanda ones might last a bit longer!

Hi there, Going to order a new wheel/tyre set for my hyper 7 and wanted to know your recommendations up to
